Yunnan Mine Tour (Anyibo Mine, Mouding County)
Go to Anyibo Mine and drive from Mouding County to Anle Township;
From Anle Township to Anyi Village:
On that day, our goal was to cross the whole mining area. Anyi platinum mine is square, with a length of 1673m, a width of 1382m, an area of 2.312/km2, and its geographical coordinates are: east longitude 1020 19' 38 ". This area belongs to Jinsha River system, and Anyi River flows from southwest to northeast through the western end of the mining area, joins Longchuan River and joins Jinsha River. The mining area belongs to Zhongshan landform with deep cutting. The highest altitude is 2008m at Liangzi Mountain in Daping, and the lowest is Anyi River Valley in the north1600m, with a relative height difference of 408m. There is a small ditch flowing from east to west in the south. The mining area is covered with vegetation, mostly barren hills, and miscellaneous forests can be seen in the depression.
Someone asked a friend who was climbing a mine why he was climbing a mine-everyone knows that climbing a mine is bitter and tiring, and there is no practical benefit. He replied, "Because the mine is there." I like this answer because it contains a sense of humor-it is obvious that I want to climb the mine, but saying that the mine is there makes him itch.
Anyibo mining area is located at the junction of the southern tip of Yanbian-Yuanshantai uplift and the central Yunnan fault basin, and three basic-ultrabasic rock complexes have been found in this area. The mafic rocks in the west of the Aoxi River intrude into the purple shale and limestone of the Sinian Dengying Formation related to the Fulongji-Aoxi fault, and intrude into the southern extension of the platinum-based ultramafic complex belt in the schist of the Kunyang Group along the fault. More than 20 rock masses have been found in this area, which are produced as rock walls or basins. Ertaipo pluton and Anyi pluton intruded into the chlorite schist of the Upper Kunyang Group, distributed in the east of Xintian Fault, produced in the basin and controlled by the secondary structure of Xintian Fault.
In Yuanshantai uplift, the basic-ultrabasic platinum-bearing rock mass is distributed in a nearly north-south belt, which is controlled by a secondary fault parallel to Yuanshantai fault. The eastern part is platinum-bearing rocks such as Zhubu and Hot Water Pond, the western part is platinum-bearing rocks of Xiushui River and Aoxi River, and the central part is platinum-bearing rocks of Anyi and Ertaipo.
The mineralization characteristics of ore types, shapes, occurrences and scales of rock bodies and orebodies in Anyi rock body are different from those in the eastern and western belts. It belongs to iron ultrabasic rock with large basin-shaped rock mass and poor mineralization of platinum and palladium.
At noon, I finally saw the ore body. Climbing mines makes people want to conquer; Upward motivation; Courage to overcome difficulties; The sense of joy and accomplishment of success. Whenever you climb the mine, you can see the geological characteristics of the deposit at your feet in an unobstructed view and have a panoramic view of the beautiful scenery. At this time, you can enjoy this beauty to the fullest. It brings you not only a refreshing feeling, but also a kind of joy and enjoyment gained after going through hardships.
Anyi pluton is exposed along the conglomerate denudation surface of variegated mudstone section in the upper part of Hongdihe Formation of Upper Cretaceous. In the northwest, the chlorite schist, Yingshi and Kunyang Groups are in fault contact with the rock mass. The southeast end is covered by Cretaceous variegated mudstone, and the new and old strata are in angular unconformity contact.
Rock mass has obvious zoning phenomenon. From footwall to footwall, olivine pyroxene, olivine pyroxene, magnetite gabbro and gabbro are the transition from ultrabasic rock to neutral, that is, from basic to vertical. All the belts gradually contact each other without mutual penetration.
The facies belts and dikes of rock mass belong to the normal series of basic → ultrabasic rocks, forming a continuous differentiation series. MgFe ratio contains olivine pyroxenite 0.94, magnetite pyroxenite 0.859, gabbro 0.76 and monzonite 0.22, belonging to iron ultrabasic rocks.
The particle size of platinum group minerals in the ore body is so fine that it can't be identified by naked eyes. According to the electron probe analysis of Guilin Institute of Gold Geology, platinum and palladium minerals were found in two types of ore bodies in this area, and it was confirmed that the platinum and palladium mineral content was consistent with that of the original ore. Platinum and palladium elements mainly occur in the form of single minerals, and platinum and palladium minerals in vein ore bodies are most closely related to sulfides. As-Pt ore, As-Sb-Pt-Pd ore and chalcopyrite are found in the timely carbonate feldspar vein ore body, which are distributed in the gangue in the form of irregular particles.
Anyi Pt-Pd deposit occurs in basic-ultrabasic rocks of Variscan stage, which is strictly controlled by lithofacies, and the ore body is layered along the lithofacies fracture zone. At present, 26,702,544 tons of Pt-Pd ore and 4.623 tons of Pt-Pd metal/kloc-0 have been obtained from the ore bodies found in the mining area. * * * The proved platinum and palladium ore amount in the mining area is (332+333) 10004659 tons, and the metal amount is 5.456 tons. The average grade is 0.54 g/t. The amount of magnetite ore is 397.68 million tons, the amount of metal is 66710.7 million tons, and the grade of magnetite 16.69%.
Anyi platinum palladium mine completed.
It's easier to go up than down. At this time, our physical strength is almost exhausted. I slipped on the soles of my feet several times and almost fell down. My friend Z keeps reminding me to grab the branches by the roadside. At the foot of the mountain, my legs were weak and exhausted, and every muscle in my body ached faintly. Z suddenly asked me, let's go for a walk by the river now. He is obviously still wanting more, so I can only grit my teeth and say "yes" with a smile.
Five hours away, the so-called "heart in heaven, body in hell" is what I feel at the moment. Although the whole body aches, but all the way over the mountains and mountains, the stream jingles. Z told me that the river in the valley would flood in summer, when there were wild flowers everywhere, which was more beautiful than now. There are many villagers working in the mountains, many of whom take their families out to work, and the family is happy. No matter who it is, everyone will take the initiative to say hello to the people coming across, and it feels particularly cordial. Later, we came to a dry valley, which was covered with grotesque and colorful pebbles. As if we were back to childhood, we "treasure hunt" here, looking for a unique stone.
I spent a day in Anyi platinum mine, but this day was far from enough to know about this mine, and time was limited. We plan to come again this year. After resting in the village, I drove back to Mouding County. From a farmland to a forest, there are mountains on both sides of the road, and the world is empty. In the distance, you can see shepherds driving their cattle and sheep home, but there is no "wind and grass". I am far away from worldly troubles, and suddenly I think of Tao Yuanming's "picking chrysanthemums under the east fence and seeing Nanshan leisurely", which is probably the scene.
