5. Look for the dew point
"I have a somewhat different opinion."
Xu Xin suddenly stood up and walked to the side of the engineering layout drawing.
Everyone's eyes were all focused on Xu Xin.
What does this young man with a childish face have to say?
For the first time in the past half a day, a young man took the initiative to speak.
He Xi put down the teacup, looked at Xu Xin with interest, and said with a smile: "Speak freely, don't be restrained." ”
"I don't think our exploration work is far from over, and we shouldn't have been in the field so soon."
"Oh? It seems that you have a different opinion on the decision of our expert group. ”
He Xi smiled in a joking tone, and did not mean to blame.
Several other experts laughed too.
"You introduce yourself first, and let a few of us old guys get to know each other." Yan Peng reminded with a smile.
"My name is Xu Xin, and I am currently a junior at Three Towns University, and I intern here during the summer."
Xu Xin was not stage frightened, and said calmly.
"Dean Yan, your alumni are all top students!"
"The students who come out of key universities are all talents."
The other four experts all laughed and joked with Yan Peng.
Yan Peng was also overjoyed, and said with a smile: "It turned out to be a junior brother, I am from the Institute of Water Resources and Hydropower, what about you?" ”
"Geophysics Major, School of Surveying and Mapping."
"The School of Surveying and Mapping of our school is one of the best in the world!"
Yan Peng didn't forget to praise his alma mater, "Tell me, if you have any ideas, speak out boldly." ”
He Xi nodded and agreed, "Young people nowadays are very thoughtful, but most of them dare not express them. ”
"Ahem, ahem, ahem......"
Xu Hengqiang coughed constantly, looking as if he had choked on drinking water.
Before Xu Xin spoke, he reminded in a low voice: "The expert group has made a decision, Xu Xin, if you have any suggestions, just tell me after the meeting." ”
The five experts here are involved in geology, geophysical prospecting, hydrology, environment and other aspects, and each of them is a highly respected senior.
Each of them has achieved a high level of achievement in their respective fields.
They are either professors, researchers, or senior engineers, experienced and well-informed.
You, an intern student, what kind of stinky fart can you promote?
He thought that Xu Xin was young and vigorous, and he didn't know the importance of it, and he stood up for them at this kind of meeting.
If you really want to do that, you're not going to help.
Jiang Yehu hurriedly pulled the corner of Xu Xin's clothes.
Xu Xin insisted on going his own way, bent down and pulled the project layout in front of him, and clicked on an area above, "I think we can try to drill a few holes here, it doesn't need to be deep, about two hundred meters." ”
When several experts heard this, they stood up one after another, gathered around Xu Xin, and looked at the direction of his finger.
They didn't despise Xu Xin's words because he was young, and they all looked at him seriously.
He Xi looked for the nearby stratum code, and said suspiciously: "This is the south of the fault, and the outcropping lithology is dolomite, which is already the bottom plate of the ore layer, and there is no basis for drilling." ”
"No," Xu Xin picked up a pencil and drew a line about a kilometer south of the red line representing the fault, "There is still a fault here, go south, the ore layer has not weathered, it is still well preserved." ”
Upon hearing this, several experts looked even more serious.
Obviously, Xu Xin's words have a certain amount of truth, and they are not nonsense.
"Did you find the dew over there?" Questions were raised.
Xu Xin didn't see any dew points.
Otherwise, with the conscientious attitude of geologists over the years, it is impossible not to see it.
Instead, he nodded in the affirmative.
It is impossible to say that he has superpowers, he can see through the stratum and directly see the ore layer one or two hundred meters underground.
"I went to shit just now, and I was holding a trace element analyzer in my hand, and I accidentally measured the dew point with a high molybdenum ore content!"
Xu Xin said it vigorously, and it seemed that there was really such a thing.
"Let's go, take us to see that bubble of!"
He Xi'an couldn't help but be excited, picked up the teacup and walked out.
No matter which geological person it is, when I see minerals, I am always excited and full of a sense of achievement.
The dew point is impossible to find.
Xu Xin was difficult to ride a tiger, and he couldn't find a better explanation for a while.
I had to take the team of experts, follow the path, and go south again.
From the project department to the dew point in his mouth, there is a mountain road of nearly two kilometers.
All of them were elated.
Xu Xin took twenty people and walked around the mountain for most of the day, but he couldn't find the so-called dew point.
According to him, the dew point was only the size of a fist, and it was pitch black and soft.
This statement is very similar to the weathering characteristics of carbonaceous mudstone.
It's getting dark.
Several experts are all old, except for Yan Peng, who is in his forties, the other four are all sixty or seventy years old, and they can't stand the toss.
When he stopped to rest, He Xi suddenly beckoned to Xu Xin, "Xiao Xu, you hand me the geological hammer." ”
When he got his hands on the hammer, he tapped it on the stone under his buttocks, picked up a peeling stone, and examined it carefully.
"The floating soil here is heavily covered, and the rocks are less exposed, so if you don't look carefully, you really miss it."
Hearing him say this, several other experts also picked up the stones scattered on the ground and looked at them carefully.
"Lad, give me nitrates."
Hearing the greeting of the leader of the expert group, Jiang Yehu hurriedly took out a bottle of low-concentration nitrate from his bag.
He couldn't help but secretly luck in his heart, fortunately he brought nitrate, otherwise he couldn't take it out at this time, and it would be a low-level mistake for geological work.
Nitrate drips on the fresh stone face.
Zizizi......
The liquid bubbles on the stone, and the reaction is violent.
The five experts glanced at each other, and they all saw a look of shock in each other's eyes.
Xu Hengqiang and the geological staff under his hands also looked incredible.
They all thought it was all Dolomites.
As a result, they were all wrong.
The fault is empiricism.
I took a large-scale zoning map, and after zooming in, I used it directly, and I didn't do detailed surface work in this area.
"It's limestone!"
Even if everyone saw it, He Xi couldn't help the surprise in his heart and exclaimed softly.
It is a conclusive conclusion that the coffin is conclusive.
What does this mean?
This formation is not the floor of the ore layer!
It's a layer that is younger than the age of the mine!
"How did I forget!"
Xu Xin patted his head, and then remembered that when he first discovered a new fault, he found a difference in the outcropping lithology of the surface.
My mind is full of ore seams, and I forget the simplest and most direct evidence.
I wandered around in the mountains for a long time.
"Good!"
He Xi looked at Xu Xin's eyes full of affection, and said approvingly: "Xiao Xu, you, you have taught us old guys a lesson!" ”
Xu Xin looked confused.
Xu Hengqiang also realized the negligence of the geological work on his side, and quickly stood up and spoke: "Starting tomorrow, we will carry out surface work in this area again, and we must find out the geological situation here!" ”
"Okay, we must check it out!"
He Xi didn't blame Xu Hengqiang, and couldn't hide the excitement on his face, "If the ore layer can be found here, then this project is not just as simple as a small deposit, and it may even be a medium-sized deposit, or even a large deposit!" ”
"It's getting dark, and the mountain road is difficult to walk, why don't we go back?"
"Let's get here today, and we'll come back when your investigation results are available."
When we walked back, everyone's steps were much lighter.
Jiang Yehu pulled Xu Xin and said suspiciously: "Did you really run a kilometer away to?" ”
