Lead and zinc mine is located in northwest Guizhou into the Yangtze in the southwest edge of a small river, Shizong - Maitreya, Yadu - Ziyun three deep faults are confined in the region, is Sichuan - Yunnan - Guizhou important lead-zinc mineralization domains part of Guizhou Province, is also an important lead and zinc origin. District lead-zinc deposit (point), geophysical and geochemical anomalies in groups and with distribution, favorable geological conditions, exploration prospects, with looking in the potential for large deposits. Lead and zinc mine in northwest Guizhou into a regional structure distribution, lead-zinc distribution with obvious zonal distribution characteristics. According to this thesis, Academician Chen YC, Pei Rongfu academicians about China metallogenic belt division plan, lead and zinc mine area in northwest Guizhou combined structure and mineralization characteristics, divided into four tectonic belt, three mineralization subzones, a more detailed description of the regional tectonic evolution, the tectonic zone, subzone metallogenic geological characteristics and metallogenic characteristics, geophysical and geochemical anomalies and the relationship between lead and zinc mineralization. Lead and zinc ore mineralization factors that lead-zinc mineralization in this area by strata (S1-2hj-P2m), lithology (carbonate), igneous rocks (diabase flanking basalt layers below), facies (on clay (page) facies carbonate facies stacked next combination), depositional environment (underwater ridges inside, closed - semi-enclosed lagoon reducing depositional environment) control. Ore than lithologic horizons, regional main ore-bearing horizon from west to east, from north to south on the spatial distribution of gradually rising, the time evolution gradually become a new, Sinian-based Southwest to Northeast Yunnan in order to shock → Once the Department, the Lower Cambrian to Carboniferous mainly dominated → Northwestern. Deposit portfolio consists of Cu-Pb-Zn → Pb-Zn-V → Pb-Zn (Ag), which shows the low level of erosion in Northwest Guizhou, ore-bearing horizon preserved, deep prospecting potential. Faults is the most important ore-controlling factors, structural characteristics of ore grading obvious that rift basin edge control belt tight folds of its distribution → longitudinal fault core developmental control ore field distribution within the main fault and mine → intersections of secondary faults, anticlines and ore deposits tilt-side control output. Regional faults subprime squeeze off interlayer fracture zone (inter-layer sliding surface, traction prostration space) is a good supporting structural control and guidance system, polyethylene, ore storage system. Region Pb, S, C, O isotopes, REE characteristics typical deposits of ore and rock Pb / Zn ratio characteristics, regional geochemical background field characteristics show a mineral with multi-source, multi-stage mineralization with sex. Ore-forming elements Pb, Zn, Ag mainly from the underlying old strata, and Lower Cambrian rocks, pre-Sinian basement volcanic rocks, but also with the Emeishan basalts and diabase intrusion earlier phase Bit successful student contact. Ore-forming fluids S, 0 from marine sulfate, C derived from marine carbonate ore-forming fluid water mainly from deep strata metamorphic water, mixed with a small amount of precipitation. Mineral inclusions show the nature of ore-forming fluid is low, high salinity, strong reducing conditions, weak reduction - a weak acid, high salinity of Ca2-Na-Cl-(SO42-) type hydrothermal. Genesis types with the world's MVT (MVT) lead-zinc deposits, compared with similar, but superficial vein minerals out steep obvious characteristics, is not a typical MVT deposit. Combined with regional tectonic evolution, geological characteristics, ore-controlling factors and metallogenic comprehensive law, the establishment of the area into multiple sources of minerals, multi-stage mineralization MVT mineralization patterns and to faults as the main controlling factor for looking Mine mode. The metallogenic belt typical deposit (area) prospecting potential and metallogenic prediction that deep prospecting in Northwest Guizhou has great potential, with large deposits looking for in the conditions. Important prospecting targets for the hezhang MAOMAOCHANG - virgin child deep mines area, Yadu - python cave fault zone Yadu, Shau Kei Wan deep mines and periphery; Watertown Castle and the peripheral deep mines, mining deep cedar forest; Granville Ning silver factory slope mine deep. Superficial vein to find the steep main type fracture, deep second ore space (greater than 500M) to find stratoid dominated interlaminar fracture type, indicating the direction of the area in the future and the main types of ore.
