That's it?

Didn't you say that Li Dingan has been tossing and turning blindly?

The left hand is lanolin gangue, the right hand is basalt, and the left friend is looking back and forth.

But he only knows a little bit about geology, and he really can't see why.

"Lao Wan, Lao Bu, what do you think?"

"Theoretically possible!"

"Actually?"

"It's very difficult to operate!"

Perhaps thinking that such an answer was too perfunctory, Director Bu organized the wording: "It's like: a piece of gold-bearing ore was found in the mountain, and if you want to find the vein with it, you need a lot of investigation and exploration...... Anyway, it can't be done in a few months! ”

That's true.

But Zuo Peng found that if he was replaced by Li Dingan, many reasons didn't seem to work?

Anyway, he has been doing archaeology for so many years, and for the first time, he has been competing with a mountain in order to find the kiln site of a porcelain kiln.

The question is, did he really find his eyebrows?

He put down the stone, clapped his hands, and walked behind Li Ding'an.

Li Ding'an and Ma Xianming stood side by side, standing at the location where the mutton fat gangue was found:

"The salt base of lanolin gangue is low in leaching, and the leaching is also low, and there will be crystals stored on the surface, and then weathered, it will be converted into iron and aluminum clay, and further, it is red clay. But this thing has a relatively high degree of leaching and leaching, and it will not remain on the surface, but will disappear......"

"How did you disappear?"

"There are two ways: first, rainfall, which penetrates into the ground through water, and second, soil erosion, which shifts down the mountain again......"

"Where?"

"Here, here, and here!"

Li Ding'an pointed to the three depressions under the mountain, and then pointed to the gorge next to the depressions, "Part of it has been dug up, and the rest should have been washed away!" ”

"Scooped?" Ma Xianming suddenly realized: "These three depressions turned out to be porcelain clay pits? ”

"Nine times out of ten!"

"But why is it buried?"

"There are many reasons, but you can't escape geological disasters: earthquakes, mudslides, landslides, collapses, etc., all of them are possible!"

Li Dingan walked down, "Which one is it, just explore it!" ”

Ma Xianming hurriedly followed, and Zuo Peng was also about to follow, he raised his foot, but stopped again.

Director Bu scratched his ears and scratched his cheeks, bared his teeth and grinned.

"What's wrong with you, toothache?"

"It's not...... I feel that what Mr. Li said, the possibility is ...... Seems big? ”

Zuo Peng was stunned for a moment, not knowing what to say.

Who just said that the theory is feasible, but the operation is very difficult?

Did you have two minutes to finish?

He sighed and hurried down the mountain.

There are a lot of people around the mountain: the field group, the experimental group, and even the data group.

Whether you are busy for more than half a month or not, whether you can pack up and go home tomorrow depends on this.

So, I was very excited.

Li Ding'an stood in the middle and assigned tasks:

"The first group drilled at the top of the mountain, taking care to avoid the peaks and rock formations, looking for thick soil layers. The depth is temporarily 5 meters, with 50 centimeters as the boundary layer, and samples are taken layer by layer......

The second group took soil at the edge of the No. 1 depression at a depth of 10 meters and 50 centimeters per layer, paying attention to the integrity of the soil layer. The third vertical drilling rig was drilled at the centre of the No. 3 depression to a depth of 20 metres...... The experimental group did a good job of soil analysis...... Data group, do a good job of video recording ......"

The speed is very fast, copy the tool, copy the tool, load the drill rig, mount the camera, rack the camera.

The steel Luoyang shovel, the shovel head is 60 centimeters long, the rod is half a meter long, "dong dong" more than a dozen hammers, the shovel head is smashed into the ground, a twist and a lift, the soil layer is brought out.

The researcher poked up to analyze the soil layer, and the field team lifted the second shovel and continued to drill down.

Xing Feng led the team to install the drilling machine, and with a "buzz", the arm-thick drill bit cut into the butter like a red-hot knife, and drilled into it in the blink of an eye.

Luckily, I didn't touch the stones.

The machine stopped for a while, the drill pipe was connected in the field, and the experimental group took samples from the drill pipe as soon as possible.

Everything is in order.

With little effort, Yao Chuan and Cheng Yongquan carried a Luoyang shovel and ran to Li Ding'an: "Teacher Li, look! ”

Yao Chuan pointed to the end of the shovel, which is close to the surface, where the soil layer is brown. This is the reason for the presence of moisture in the soil, if it is dried, it will be loess, which is a common soil quality in the Tongliao Plain.

But it is not thick, it is only more than ten centimeters, and it is all sandy soil below.

Li Ding'an grabbed a little and twisted it carefully: silt sand, and dead clay?

"Where did you get the sample?"

"No. 2 Depression Center!"

Depression Center, shouldn't it?

If the pit is buried due to debris flows, landslides, or collapses, there will be no difference in the shallow soil quality, it will still be loess, not sand, and at most there will be no biotic layer.

The point is, whether it is silt or dead clay, it is formed at the bottom of the water, how can it run up the hillside?

If it was formed in ancient times, it would only exist below the earth's surface, at least three meters deep......

After thinking about it for a while, Li Ding'an suddenly realized: "This should be the sand gushing caused by the earthquake, and the water that washed up from under the sedimentary layer saturated the sand layer...... Data group, check the largest earthquake in Naiman after Daoguang......"

There was no need to check at all, Director Bu blurted out: "In 1940, there was an earthquake in Baxian Tube Township, with a magnitude of 6.5 and a intensity of 9!" ”

"Distance!"

"Ninety kilometers in a straight line!"

That's enough.

The Jishishan earthquake was 6.2 with an intensity of 8, and there was also a sand surge in Minhe, more than 100 kilometers away, burying two entire villages.

There are only three pits here, and they are easily buried......

Wan Chengbiao recalled vigorously: "The earthquake in 1940, why didn't you have an impression? ”

"At that time, it was the Japanese pseudo-period, there were no special geological and disaster research institutions, and there were no deaths, so there were a few yurt houses, so there was no record in the old county records...... When I visited the Yan Great Wall a few years ago, I found it from the Kailu County Chronicles......"

"It didn't have it in the original information?"

Director Bu was choked: Who said no, Kailu County Chronicles are not information?

It was when he retrieved the information that he didn't associate it with it at all......

Suddenly, another person rushed in the distance, as if it was Wei Zili, the leader of the experimental group.

Laughing as he ran, his back molars grinned.

As soon as he arrived in front of Li Ding'an, he slammed his two hands forward.

It is a handful of soil, and at first glance, it is no different from the shallow soil dug out by the previous Luoyang shovel: yellow loam.

But when I looked closely, there were a few mud balls in the middle, very wet, smooth, and dark brown in color, exactly like soaked bricks.

"Where is the sample taken?"

"The interval between the No. 1 depression and the No. 3 depression!"

"How deep?"

"Between two and five to three meters!"

"Has the pH been done?"

"PH test value 5.8!"

"Silicon-aluminum rate?"

“3.2！”

Li Ding'an nodded: "It is larger than illite, smaller than montmorillonite, and it is strongly acidic...... That's right, iron brick red soil ......"

Zuo Peng leaned back, and behind him were Wan Team and Director Bu, and the two were speechless.

Do you dare to say now: theoretically feasible, but very difficult to operate?

Big fart, people just drilled a few casually......

"Mr. Li, there is another question: the porcelain kiln is not like a mine, it must be built on the surface, even if it is buried due to geological disasters, there should be a certain amount of physical remains on the surface......

This is indeed a question: not to mention the porcelain pieces, how many kiln bricks and tiles should there be?

Unless half a mountain falls......

"I'll think about ...... again"

Li Ding'an groaned, "You guys also look for it again to see if you can find the remaining porcelain clay layer, and in addition, send a group of people back to the villa to measure the percentage of porcelain clay in the soil!" ”

"Teacher Li, this also needs to be tested?"

"I suspect that the reserves of porcelain clay here are not high, so the porcelain kiln has not existed here for a long time, so there is no record in the historical materials......"

Wei Zili patted his head: "I understand!" ”

The percentage does not need to be too high, below 20 percent, there is no value in mining, and the kiln will of course have to be relocated.

Looking at the three depressions again, and inferring from the nearby soil quality, the depth will not exceed 30 meters, otherwise there is a risk of collapse at any time.

Then calculate the volume...... Even if it is a family workshop of about ten people, it can last for thirty or forty years at most......

Wei Zili turned around, and Ma Xianming came over again: "Is there such a possibility: the porcelain kiln was not buried, but washed away, for example, after the earthquake, there was a large mudslide?" ”

"How far can you go?"

Ma Xianming was stunned for a moment and stopped talking.

The problem came back again: no matter what it was, there were at least relics left around it.

The problem is that no trace has been found now......

After thinking about it, the walkie-talkie on Li Dingan's shoulder rang twice: "Teacher Li, I'm Xing Feng...... I drilled three places at 20-metre intervals on the top of the mountain, and the soil structure was basically the same: stone chips, montmorillonite and mica, lanolin gangue and metahalloysite, bauxite ......"

Zuo Peng only knew a little bit about it, and asked Director Bu in a low voice: "What are these types?" ”

Director Bu sighed: "The four material states before the basalt developed into brick-red loam clay represent the four weathering stages at the same time......"

Doesn't that mean it's all right?

There is basalt on the top of the mountain, the product of various weathering processes, and the final form of iron brick red soil has been found at the bottom of the mountain......

as well as ravines in the mountains, depressions under the mountains, layers of sand that were originally under sedimentary layers, and seismic data......

Suddenly, Zuo Peng thought of the conversation with Li Dingan in the morning:

"Teacher Li, you've almost turned over Qinglong Mountain, where is the kiln site?"

"Probably buried!"

"Where's the burial?"

"Looking!"

"Then why did you run to the top of the mountain again, and the kiln site was buried on the top of the mountain?"

"Of course, the kiln site is not on the top of the mountain, but there are stones on the top of the mountain...... If you find the stone, you will find the china clay, if you find the china clay, you will find the pit, and if you find the pit, you will find the kiln site......"

At that time, I felt very nonsense, and I thought that Li Ding'an's way of thinking was different from ordinary people?

Others follow the clues and follow the traces, but Li Dingan first assumes a result, and then works backwards.

What if the result doesn't hold up?

But now......

To be honest, Zuo Peng also has a bit of a toothache.

Suddenly, there was the sound of a car starting in his ears, and Zuo Peng suddenly raised his head.

It was Xing Feng's pickup truck that pulled tools, at this time Li Dingan was sitting in the driver's seat, Ma Xianming was sitting in the co-pilot, and Shu Jinghao and Fang Zhijie were sitting behind.

"Teacher Li, where are you going?"

"Let's take a look over there!"

"Wait, take me...... You don't have to get down, I'll just sit in the back! ”

Fang Zhijie moved in, and Zuo Peng squeezed into the back row.

Li Dingan kicked the accelerator, and the pickup truck emitted a puff of black smoke and drove away.

Wan Chengbiao and Bu Zhimin were stunned for a moment, jumped on the cross-country with a "whoosh", and were just about to start, Yao Chuan chased after him again: "Wait for me...... I've found the kiln site soon, why don't I have to take a look? ”

The two looked at each other: staring.

Starting the car, Bu Zhimin let out a long sigh: "Team Leader Yao, I have opened my eyes this time!" ”

"What are the eyes?"

"I'm talking about Mr. Li, and his method, and...... Well, the way of thinking! ”

It is no exaggeration, when Xing Feng said that he was going to go to Laodao Mountain and drill rock formations, he really wanted to scold his mother: We are an archaeological team, not a geological exploration team.

Is there a chicken feather relationship between rock formations and porcelain kilns?

Look, is it related?

Yao Chuan nodded subconsciously, and his heart was empty: Who said it wasn't?

Not to mention Wan Chengbiao, even if it is the project team, even this morning, there are still many people who doubt: looking for a kiln site from the top of the mountain...... Mr. Li's brain hole is getting bigger and bigger, and his ideas are getting weirder and weirder?

Now, is it strange?

When I think about it, I feel that my face is hot......

After thinking about it, the car drove down the foot of the mountain and drove to the edge of the ravine.

Not far, less than five hundred meters from the nearest depression.

It is very wide, more than 20 meters by sight, but not deep, only five or six meters.

The bottom of the ditch is gravel and gravel, and the two banks are loess, which is a typical trough-shaped valley formed by floods and storms.

There are many such trenches in the area of Qinglong Mountain, because the soil is loose and the vegetation is too little, and it will collapse at every turn. Even now, it is not uncommon for houses and farmland to be buried.

Finding a gentle slope, Li Dingan went down to the bottom of the ditch and looked along the side close to the mountain.

The soil layer of the ditch wall is very uniform, mostly loess, occasionally interspersed with one or two layers of gravel and fine sand.

This hierarchical environment has a lot to do with the geological structure of the mountain: what happens to heavy rains and floods that wash down the mountain, this layer is what it is.

As he walked, Li Ding'an stopped.

Zuo Peng came up and took a look: "Why is it different here?" ”

It's really different: everywhere else is loess, but this is sand?

Is it also a sand surge?

Not exactly, it seems to be mixed with some black soil.

Tongliao is located in the northeast, and it is normal to have black soil, so I don't feel strange?

Just as he was suspicious, Li Dingan grabbed a handful of soil and shook it gently.

After a while, the black soil-like material was sifted to the surface.

He twisted it with his hand: "I see! ”

"What?"

"The way to take the porcelain clay is a combination of open mining and cave mining, and the kiln mouth is built on top of the mine, and when an earthquake occurs, it causes the goaf to collapse, and the uproar is ...... It's all sunk, so I can't find any traces? ”

Li Ding'an pointed to the black substance in his palm again: "This is not soil, but ash: the residue of calcining coal and charcoal...... After the earthquake, there was a sand surge and it was squeezed out...... Old horse, shout excavator ......"

Ha, the porcelain kiln is down here?

Ma Xianming stared at the ditch bank in a daze, and the scene in the morning came to mind:

"Teacher Li, after digging the top of the mountain, do you still have to dig cliffs and valleys?"

"Don't say it, it's possible."

"Don't ...... I beg you to ......"

"Okay, after exploring the top of the mountain, I'll go home......"

Suddenly, he broke out in a cold sweat: If it weren't for Li Ding'an's insistence, let alone next year, he might not be able to find it for another ten years.

But who would have thought that the kiln site would be buried beneath the valley?
