Nick Bo Hekou County Of Yunnan Copper Nickel Polymetallic Mineralization And Geological Prospecting Targets Background Preferred

The ming area is locate in the zone of Yaoshan township where is belong to the Hekou in Yunnan province. It is close to Socialist Republic of Vietnam. The Regional structure is handover parts of Tethyan-Himalayan tectonic domain and circum-Pacific tectonic domain. It is on the honghe sutures of The Yangtze plate and the qinghai-tibet plate transfer parts, And it Across two first-order tectonic units that is the Yangtze paraplatform and the south China fold system. This study through that the system of field geological surveying, the research for petrology, supplemented by geophysical and geochemical data to research copper-nickel polymetallic metallogenic of Nibo geological background mining area. And combined with the integrated geophysical-geochemical data to prediction prospecting target area and target optimum. To solve the ore deposit location,metallogenic regularity and ore-controlling factors of Cu-Ni-PGE sulfide deposits, and provide information for the further exploration and development of the mining area.Using the geological background, Geophysics and geochemistry to omprehensive forecast analysis of mining area. Division in the zone of magnetic anomaly area and geochemical element anomaly area. And combined with geological background delineated prospecting target and target optimum.By this research, we can get some important cognitions as follows:1. Complex structure of the position of mine. There are to with fault structure and ductile shear belt of regional structure in the Mining area, and it development many different age of fault and fault structure, and many shear bands of Cenozoic or fault what is break to Amputation that is put first in suture zone. The research shows that the Cu-Ni-PGE sulfide deposits is be in the mine mainly originated from basic-ultrabasic rock, and it is product from molten magma in the deep of earth what is injection the surface. Molten magma is Along the formation and fracture penetration that have been controlled by structure. The main activities is from hercynian to Indosinian. In the later, the dynamic metamorphism of Yanshanian and Himalayan period impact on it for transformation.2. All the rock is containing ore in ore body Because of the rock is all most mineralization pyroxenite in mining area. Mineralization is inhomogeneity that due to a lack of uniformity in ore grade differences and different areas. It show that magma of ore and pulp from the formation phase separation in order to magmatic injection by the ways of pulse into mineralization. It be called Deep magmatic liquation injection pulse type deposit.3. Based on the results of magnetic survey, that magnetostratigraphy is obviously in mining area, And in different periods and lithology are corresponding to the different magnetic field. Basic rock has the highest magnetic field intensity in the region. Magnetic anomaly is strip distribution on both sides of Alonggu-longshan fracture. It is due to the Permian basalt which is weak magnetism and he sporadic exposed basic rock. It instructions that Permian basalt (P1-2β) have weak (magnetic) contains iron and titanium. Sporadic exposed the basic rock body (vein) have higher iron and titanium. Overall, iron ore is weak zone (magnetic) with titanium, iron and show the relationship between iron and titanium were positively correlated.4. According to the measured results of soil secondary halos. The of element background "Cu, Fe, Ti, Co, Ni, Cr, V" is higher in Mining area. It Mainly distributed in Permian basalt, the second paragraph of Yaoshan group, the fourth paragraph of Yaoshan group, the fifth paragraph of Yaoshan group, and the Gonggukou-Basa fault zone. The element background of "Au、As、S、Hg" is low, so the " Au" may come from deep source, and the distribution and reaction is like to elements of basic-ultrabasic rock; The As and Hg are what is mainly distributed in the fourth paragraph offYaoshan group, the fifth paragraph of Yaoshan group and Lgukou-Ba fault zone is high element background.4. On the superposition the information of geological, geophysical and geochemical exploration achievements to estimate that the level1prospecting target area is2:Cu-Ni ore prospecting target area In Shuicao village,and magnetite prospecting target area of Tiantou village. And the level2prospecting target area is3: Cu-Ni ore prospecting target area of Nibo village. Cu-Ni ore prospecting target area of east of the Nibo village, magnetite prospecting target area of east of the Tiantou village.
