"I've always heard about your deeds, Master Liu, and I never thought that I would be lucky enough to meet you today!"

"Yes, you've been my idol since I was a child!"

Facing the enthusiastic crowd around him, Liu Yiyan smiled and said, "Everyone is polite!

"Haha, Master Liu is humble!"

Hong Ying laughed on the side, squeezed his eyebrows at Chen Song and said, "Master Liu at the Taishan level, I came here specifically to ask you for help this time!"

"Looking for my help?"

Chen Song was stunned.

This Liu Yiyan is already the top Xiangyu master in the Xiangyu world, what can I do to help him? I don't understand anything!

Yang Hao saw Chen Song's doubts, and said happily: "Chen Song, isn't the small ore vein we are responsible for mining more and more good jade dug up recently? And you also dug up the jade rough of the dragon stone species before, so my master is very interested in this small ore vein where the jade rough of the dragon stone species appears, and wants to go in to see this small ore vein, and study its geology and rock formations by the way!"

Hong Ying also smiled on the side: "Yes, Chen Song, the dragon stone jade rough was discovered by your kid at that time, you have to tell Master Liu about what you found and excavated at that time!"

"Okay!"

Chen Song couldn't imagine that Liu, who was a master of Xiangyu, would find himself for such a trivial matter, and he readily agreed.

"Then there is Lao Xiaoyou!"

"Master Liu, you're polite!"

Because of Master Liu Yanyan's coming, the staff of the second class quickly finished the breakfast in their hands in order not to delay his time, and walked towards the pit while chatting.

Along the way, people constantly recognized Liu Yiyan and greeted him respectfully excitedly, and Liu Yiyan responded politely.

"The Dragonstone Seed Jade Rough Stone was dug up in this location, but now it's like this!"

Coming to the mining area in charge of the second class, Chen Song pointed to the entrance of the small ore vein and said a little embarrassed.

The place where the original excavated dragonstone planted the jadeite rough has become the entrance of the small ore vein at this time, and with the downward excavation, it continues to extend forward, and it has been dug into a channel.

"This ...... It's all about to dig into the road, how can you look at digging out the soil around the dragon stone jade rough!"

Hong Ying couldn't have imagined that in just a few days, this place would change a lot!

He completely underestimated everyone's enthusiasm for this vein, if it weren't for the restrictions of the mine rules, the second shift would not be able to mine at night, and it is estimated that this place has been dug up now!

"It's okay!"

Liu Yan squatted down, carefully looked at the soil pointed by Chen Song, reached out and grabbed a handful, and observed in his hand with a gleam in his eyes, this reddish-brown soil seemed to be some rare treasure to him.

Hong Ying looked at Liu Yiyan's movements, scratched his head in puzzlement, and muttered: "What can you see from this?

Yang Hao was next to Hong Ying, and when he heard his words, he couldn't help but smile and said, "Jadeite, as a rock, is a collection of many minerals, and common minerals are roughly divided into three categories: pyroxene minerals, amphibole minerals and feldspar minerals. In addition, other minerals, such as chlorite, serpentine, etc., are occasionally seen......"

"There are only two types of rocks that can form jadeite, granite and diorite. Both rocks contain quartz, feldspar, mica, hornblende, pyroxene, olivine, etc. These minerals are under the conditions of high temperature and high pressure or high temperature and low pressure, which can be continuously decomposed and metamorphosed, and finally combined into jadeite, which is also the basic cause of jadeite. ”

"Among them, the veins are divided into primary ore and secondary ore, among which the highland gravel layer jadeite placer, because of the considerable accumulation thickness, so the deposit is usually divided into three layers: the surface layer often has bright color but coarse texture of jadeite quality. In the middle layer, you can see jadeite varieties with good texture and color, and high-quality jadeite with green color, good water and dense structure can be found in the lower layer. ”

Hong Ying was even more foggy after listening to what Yang Hao said, what is this?! Anyway, he didn't understand a word!

But Chen Song's eyes lit up, and he asked, "Brother Yang, what is the difference between the primary ore and the secondary ore of this jadeite?"

Yang Hao thought for a while and said: "Primary ore refers to the mineral deposits that have never been moved by natural forces after jadeite is mineralized, that is, earthquakes, volcanic eruptions, wind and rain, river transportation, etc., but are covered by soil and rocks, and the ore has not been weathered or the degree of weathering is small. ”

"Secondary ore refers to jadeite mineralization after undergoing long-term weathering, and a variety of external stress to form a different shape, with the skin of jadeite raw materials, it is also known as placer ore, placer ore or exposed to be easy to be found, or covered by debris flow, must be excavated to find. ”

"Yang Hao, you're right, but you still missed one, that is, primary to secondary deposits!"

Yang Yanyan, who was looking at the sand in his hand, heard Yang Hao's words, and couldn't help but correct him.

"Primary to secondary deposits?"

The crowd was puzzled.

"Primary to secondary deposits, that is, primary deposits, are jadeite deposits that have not undergone strong enough weathering erosion or water flow impact and transportation, and are in a state of broken deposits. ”

Liu didn't raise his head at a glance, and continued: "Among the primary, secondary, and primary to secondary jadeite deposits, the probability of high-quality jadeite appearing in the secondary deposit is the most, and this is also the most valued vein!"

Liu Yan suddenly turned to look at the three of them, and asked playfully: "The jadeite produced by Yang Hao said just now is rough in texture, do you know why?"

"That, master, I really don't know!"

Yang Hao was bitter in his heart, he had always relied on himself to explore, and no one had taught and instructed him.

Chen Song and Hong Ying, as laymen, don't understand it even more!

Looking at the silent three, Liu Yiyan sighed and said: "There is a point of view in the geological and jewelry circles, that is, that water can raise jade, and if there is water, the jade has spirituality, and if there is water, it will be transparent! But the real reason is that the jadeite and jade of the secondary deposit have been soaked or alluvial by surface water or groundwater for a long time, and under the addition of trace elements in the water and other geological actions, a water-rock reaction has occurred, which promotes the benign development of the structure and structure of the jade, and at the same time will make the trace cracks in the jade material heal. And the dragon stone jadeite is born with the connotation of the dragon and water, which is the environment and conditions for the formation of the deposit!"

"This ...... Master Liu, I still don't understand what this has to do with looking at the soil!"

Regarding Hong Ying's sudden question, Liu Yiyan felt that he was really playing the piano to the cow!

Without saying a word, he turned around and continued to look at the sand in his hand.

Yang Hao looked at Hong Ying, who was still blind, and said a little funny: "Captain Hong, because of the different compositions and structures of different rocks, the jadeite they form in the end is also very different, so in the earliest days, Xiangyu masters usually judge the geological environment by observing the sand, and find the location of the ore vein according to the characteristics of the sand, and infer the size range of the ore vein and the quality of the jade material in the ore vein!"

Hong Ying understood it now, and also understood the specific use of the soil, so he couldn't help but give a thumbs up, and praised Liu Yiyan: "Sure enough, there is no void under the fame, Master Liu is worthy of being the Taishan Beidou in the jade world!"

Chen Song listened to Yang Hao's words with Master Liu Yiyan, and suddenly became enlightened, solving many questions in his heart, and at the same time secretly surprised in his heart.

I can't imagine that this jade identification is so not easy!

Even this clay contains so much learning!

If you let yourself look at it, you won't be able to see why.

To put it bluntly, now they rely on their vitality to identify the original stones, and they are all real kung fu and real skills!

Everyone was afraid of disturbing Liu, who was concentrating on studying the soil in his hand, and he stopped talking.

Master Liu Yanyan pinched up some dirt from time to time, rubbed it, and watched it carefully.

In the end, he took an iron pickaxe and dug it in place, looking at the exposed dirt, sometimes frowning, sometimes surprised, and finally showing such an expression.

It's half a ring.

Only then did he get up and praise Chen Song and said: "Xiaoyou is really a good jade relationship! This location is not the best in this small ore vein, and it can even be said that it is completely on the edge of the small ore vein! It stands to reason that there will be no dragon stone jade rough in this position, at most it is only ice type! But because of geological changes, the cave of the original ore deposit has found changes, and the dragon stone jade rough you found has been pushed to this position!"

"You said that the dragon stone jade rough was pushed to this edge position because the geology had changed?" Chen Song said in surprise.

"Yes!"

Liu Yiyan smiled and nodded.

Chen Song was shocked when he heard Master Liu Yanyan's words!

Remembering that the dark black stone that was dug up at that time was only two-thirds, and the remaining third could not be found when digging later, I couldn't help but say, "Yes...... The dragon stone seed jade rough I dug up is only two-thirds!"

"What!"

Yang Hao and Hong Ying looked at Chen Song in surprise.

They hadn't seen the rough stone up close, but they remembered that it was dark black and the edges and corners were smooth, and they thought it was a whole piece!

In addition, I was completely attracted by the exposed green, and there was still that change later, and I didn't notice that the dragon stone jade rough was not complete!

Chen Song thought about it for a moment and said, "There are only two-thirds of the stones! It turned out to be stuck in a pile of stones and pulled out by me, and I haven't found the broken one-third yet!"

"Xiaoyou's words have solved the old question, I have also seen the dragon stone jade rough you dug up, which is also the reason why I came here this time!"

Liu Yan said with a little excitement: "The soil layer here is obviously a combination of three layers, and there are not many mineral elements produced by jadeite, so it can basically be concluded that the cave collapse of the ore deposit caused by debris flow or other reasons, just washed the dragonstone jadeite here." The rough stone broke in the middle of the process, which is the main reason why you dig it out and find that it is not complete!"

"And where's the remaining third?"

Hearing Liu Yiyan's confident answer, the three of them all asked in unison in a little anxious.

"This still needs to be further identified! However, there are two possibilities for the decay to guess, one is that it was caught in the stone flow at that time and was pushed down to a certain place! The other is that it was directly broken by the impulse at the place where it was generated, that is, it was still producing the location of the deposit where the source of the dragonstone jadeite was generated!"

"Then let's hurry up and find it! Master Liu, you say, what do you need us to do!"

"You don't have to do anything, just keep checking the soil and rocks along the small veins!"

When everyone heard this, they were extremely excited, and even Hong Ying pulled an iron pickaxe and followed.

Every time Liu Yiyan walked a section, he dug up the soil, held the soil in his hand to identify it, and the more he looked at it, the happier he became.

Slowly, everyone entered the passage, that is, the latest place where the small ore vein was dug in.

Looking at the narrow advance, I can't help but make a difficulty!

The passage itself was dug out from the vertical side of the large slope, and the bottom of the passage was so high from the top of the large slope that the excavator had been slowly digging down from the large slope to the bottom of the passage.

To look at it now, you have to dig this passage quickly into the distance that I don't know how long.

How do you dig this?!
