Research On The Information Of Extraction From Remote Sensing Data And The Application In The East Of Zalma-Sawuer Metallogenic Belt Copper Mine

The advantages of remote sensing technology are short-term and high-efficiency,which are increasingly highlight in geological work, especially gaining agreementfrom more and more geologists in the application of extraction prospectinginformation from remote sensing data. Remote sensing prospecting informationextracted mainly includes three aspacts: special lithology extraction、 structuralinformation extraction and mineralization alteration information extraction. Remotesensing prospecting information extraction can provide the basis and guidingsignificance for the bad environment and larger areas.This article mainly study the Zalma-Sawuer metallogenic belt copper mine withthe eastern section of the southern margin of Altay in Xinjiang regional area.RegardKalatongke the magma melt from copper and porphyry copper Halasu two copperdeposits as key research objects, combining with the geological data of the twodeposits, application of ASTER data remote sensing prospecting informationextraction study of these two deposits comparatively. ASTER data pre-processing andimage enhancement, seek more accurate reflection of the image enhancement of avariety of information processing method for the extraction of two special depositlithology, geological structure and mineralization and alteration. Special lithologicalinformation, measured by the HR-1024spectrometer spectral curve of the ore samplestaken in the field, the analysis curve corresponds to the ASTER data band featureextraction two ore-deposit lithology; geological structure information extractionhigher accuracy convolution filtering and texture information enhancement methodsand visual interpretation combined extraction; alteration Information extraction,alteration and mineralization of the two deposits contain the type of alterationminerals, USGS spectral library of the United States, there are the standard spectralcurve corresponding bands of ASTER data feature extraction. Extracte lithology,structure and alteration of the information to establish the remote sensing prospecting indicators of each of these two deposits, and the use of remote sensing prospectingflag to the entire study area delineated mineralization target.
