Western Puxiong Old Lead-zinc Polymetallic Ore Concentration Area Of ​​integrated Information Metallogenic Prediction

Deep prospecting has become the trend of this stage geological prospecting has developed the practical application from the simple prospecting methods to multi-source information fusion prospecting theory. Multi-source information fusion prospecting refers to overlay analysis of the information depend on the qualitative and quantitative predictions way. The information including geology, geophysical exploration, geochemical exploration and remote sensing, etc.To form a complete information theory of mineralization, it can provide a reliable scientific basis for the prospecting of the peripheral, deep and concealed ore-bodies of the existing mine.The study area of Puxiong lead-zinc mineralization concentration in the west Gejiu under the southeastern Yunnan (Gejiu-Bozhushan-Laojunshan,) tin metallogenic belt.It is an important part of China's top ten Tin metallogenic belt. The geological strata exposed combine with the acidic granites and alkaline rocks.So,the mineralization is in good condition, because the strata similar to the Gejiu Eastern. The study theroy expected to achieve a breakthrough in the metallogenic prediction of mineral resources base on the area.Based on the research project of the lead-zinc resources analysis on potential evaluation and prospecting law in the Yunnan,Guizhou and Sichuan province bordering areas, and platformed with a geographical information system, the article superimposed and analyzed the multi-source geo-spatial information such as geology, geophysical exploration, geochemical exploration and remote sensing, etc, to determine the comprehensive information prospecting model, and used the theory of integrated metallogenic information prediction to delineation of favorable ore-forming region in the study area. The knowledge and the results obtained are as follows:1.Based on the national research project of the lead-zinc resources analysis on potential evaluation and prospecting law in the Yunnan,Guizhou and Sichuan province bordering areas, we systematically collected the study area's geological, geochemical, geophysical and other relevant metallogenic information, and supplement remote sensing metallogenic information, etc.Based on fusion and analysis of different bands'ETM remote sensing image, primary nature of the fault and the spatial distribution. The article analysis mineralization relationship about fracture, fold structure, and magmatic rocks in the area of Gejiu western-Jianshui-Shiping.We can select a representative of a typical deposit of ore concentration area:Jiutou mountain and Baixiang mountain containing silver, lead-zinc deposits lead to anatomical studies, preparation of typical metallogenic factor maps, the region some of the representative has been developed to deposit prospecting forecastthe elements of re-integration of elements of the preparation of a typical deposit forecast map and forecast model diagram.Measured by three representative geological, geophysical, geochemical profiles, we can build a iverse geospatial database while it combine geological, geochemical, geophysical and remote data.It can systematic summary of the mine pool, Lead-Zincmineralization, and identify the forecast area. Mine pool all deposits (points) occur in the strata of the Triassic carbonate rocks, by the apparent control of the stratigraphy, lithology, magmatic rocks.Using Metallic Mineral Resources Analysis System MORPAS software to calculate the weight of the prospecting factor, we could build the prediction model and generate a comprehensive weight of anomaly contour map. Results, we circled the three prospect area:Luoshuidong-Panshan(A3),Yanfengdong(A2),and Laoyingwo-Zhichang-Pujiashan(Al), to provide a sustainable basis for regional mineral exploration.
