Yunnan Province The Longling Mengxing Lead-zinc Deposit Genesis And Prospecting Flag

At present, China is in an important period of the geological development of the subject, genesis and exploration studies in the increased difficulty with Prospecting and geological development of academic disciplines and a variety of earth science application of new technologies has become an important subject. This paper based on the Kunming University of Science on "lead-zinc deposit in Yunnan Meng Xing stereotactic deep and peripheral projections and increase reserves of scientific research projects, through deep exploration of mineral resources in this forecast as an opportunity, and find the relevant genesis mine's Earth Science data collection, analysis and research. To ease the crisis and the edge of the mine and ore resources by deep storage, application and analysis of focus-forming factors and metallogenic model theory, research for the mining of ore-related basis. In June 1958, lead-zinc deposit in Yunnan Longling Meng Xing Built in Baoshan, Yunnan Longling, after decades of mining, lead-zinc deposit in Yunnan Longling Meng Xing is found in southwestern Yunnan relatively larger sulphides deposits. However, declining mine reserves. The paper work to genesis, forming the law theory, forming elements extracted information, establishment of genesis and Metallogenesis research system, to determine the prospecting criteria. The following are the main study of this understanding:1, Meng Xing lead-zinc ore fluid migration and activation to SN faults may be controlled significantly by the layer containing the control and structural control of the seam under certain geological environment enriched mineralization. The earliest development of a more stable layer in the lower Paleozoic carbonate sedimentary cycles in a continuous deposition of ore body position. Main ore occurrence carbonate clastic sedimentary layer at the bottom of the folder, sub folder ore occurrence clastic sedimentary rocks of the carbonate layer at the top, biological limestone or pure limestone (marl) are mineralized layer. China stratabound Pb-Zn deposits of carbonate occurrence and law of the eastern region of the sedimentary characteristics of this layer line. Deposit types are carbonate - transform-type deposits;2, According ray analysis, metallic minerals to generate the sequence from the late early for the flash of zinc a galena pyrite;3, Longling Meng Fu Xing zinc mine is sedimentary - transform-type deposits (quasi-situ transformation of sedimentary deposits), occurrence of carbonate rocks. Mineralization effects, secondary enrichment, the role of supergene weathering wet, layer the tectonic fracture zones and the role of diagenetic deposition of epigenetic landscape of mines basic prerequisite factors4, forming the law through the analysis of ore genesis and exploration to determine the sign. Silurian strata and containing laminated limestone, bioclastic limestone limestone formations, is a major enabling seam-bit; Showing dark brown color, red brown, yellow net vein, powder, gel, and hull shape is the lead-zinc gossans layer of prospecting criteria; Limonite deposits found in barite veins and carbonate veins are also prospecting criteria.
