Abstract
Remote sensing has always played an indispensable guiding role in geological prospecting.From the relatively single low-resolution remote sensing interpretation in the early stage to the current changes in high-spectral,high-resolution,multi-technical means,and multi-spatial levels,remote sensing has provided more new ideas and methods in geology,making the application scope of remote sensing in geology wider and wider.This time,Landsat8 data will be used to extract remote sensing alteration in the Huajialing area of Tongwei County,Gansu Province,and the extracted results will be combined with the geological background,geochemical anomalies of water system sediments and aeromagnetic anomalies in the area to screen the remote sensing alteration anomaly area,and finally delineate the remote sensing anomaly area.After field investigation,the remote sensing anomaly area has obvious geological prospecting indication effect,and many tungsten ore bodies have been discovered,which have been identi.关键词
