The Research Of Romote Sensing Abnormity Extraction And Copper Mul-metal Mine Prediction In Tuwu And Huang Shan Region Of Xin Jiang

On the basis of systematic summary of mineral prospecting work in the Eastern Tianshan Mountain, aiming at a breakthrough of mineral prospecting in Tuwu-Huangshan metallogenic belt in Hami area, remote sensing technology is taken to use to carry out the remote sensing mineral prospecting potential assessment in the area of Easten Tianshan Mountain, provides the exploration target area for geological prospecting and offers the decision-making support for geological exploration deployment in the area.This research is to start with the modern metallogenic system theory, considering the Porphyry Copper Deposit and Magmatic Cu- Ni Deposit as the main direction, to dominantly apply multispectral remote sensing technology to perform the research on quick assessment modeling of mineral resource by the multi-information ( geological, geophysical, geochemical and remote sensing information) comprehensive analysis.After summarizing and analyzing the regional metallogenic geological characteristics, deeply analyze and study typical deposit; making use of the ETM data to carry out the regional remote sensing geological interpretation and information extraction. This research is about to conduct the large area remote sensing anomalies extraction and capture the alteration anomalies that relevant to regional metallogenic effect and the information of mineral distribution rule.By the hyperspectral remote sensing mineral mapping research using ASTER and HYMAP data, conduct the alteration mineral mapping and extract the alteration remote sensing anomalies aiming at the dominant alteration mineral combinations in Porphyry Copper Deposit and Magmatic Cu- Ni Deposit. Considering the copper deposit remote sensing mineral prospecting information extracted from ASTER and HYMAP data as the standard, carry out the large area alteration remote sensing anomalies extraction and filtration by ETM data.By multi-resource geological information comprehensive analysis, integrating and studying the geological, geophysical, geochemical and aeromagnetic gravity data, analyze the ore-controlling factor and relativity rule of remote sensing anomalies of Copper Deposit and Cu- Ni Deposit in the study area, circle the remote sensing mineral prospecting target area and commend and predict remote sensing anomalies area, to carry out the remote sensing mineral prospecting potential assessment and choose some of the target area to make the field check. This method achieved a good application effect.Firstly experiment to do a large area remote sensing application research in Easten Tianshan Montain area, this research provide remote sensing documents for mineral resource investigation and evaluation and promote the reasonable and orderly deployment of Copper prospecting in Tuwu-Huangshan metallogenic belt in Easten Tianshan Montain, with the expectation that achieve the new breakthrough of cooper prospecting in this metallogenic belt and further promote the mineral prospecting work in Easten Tianshan Montain area, even the whole Tianshan Montain area.
