The Characteristics Of Tectonic Ore-control And Prognosis Of Concealed Ore Body In The Nasitai Lead-zinc Deposit, Chifeng Area

With the rapid development of economy, China needs to increase the mineral resources, and many minerals have been identified for declining reserves and supply capacity, commodity prices became significantly higher, resource bottlenecks highlighted and there have urgent need for significant exploration of new breakthrough. The Nasitai lead-zinc deposit in Chifeng is located in the South of Daxinganling, which is a south part of the Huang Gang - Kanjur Temple of Tin, Lead and Zinc (Copper) polymetallic ore belt. Study area mainly developed late Paleozoic Carboniferous - Permian and Mesozoic and Cenozoic; Mesozoic magmatic activity frequently; Magmatic rock band NE to the distribution.the area of tin, copper, lead and zinc metal mineral wealth. To carry out that Chifeng Nasitai lead-zinc deposit this feature of structural control and lead-zinc ore body buried prediction and evaluation of research projects to guide the deployment of prospecting has important practical significance.Mining field survey carried out geological studies, summarized the law mineralization and prospecting, prospecting primary section to guide the rational deployment of geophysical exploration engineering Ore bodies in the NE, NW and NEE to the fault fracture zone, NE layer to the fracture zone and skarn control to the main NE. Among them, the fold of rock layers and sub-detachment folds with near side of the collapse transition ore output with a favorable position.Using very low frequency geophysical techniques and methods of prospecting section on systematic exploration, delineation of shallow mineralization zone (body) of the spatial distribution characteristics, preferred target for exploration. EH4 and other geophysical techniques used for optimization of ore mineralization zone to zone (body) growth characteristics of deep exploration, combined with features of mineralized comprehensive spatial analysis to guide the deployment of prospecting works.Further use of EH4 and other geophysical techniques, exploration of the optimal section for mineralized zone ( physical) characteristics of deep exploration and development to guide the deployment of prospecting works.
