| 摘 要： | 文章将蚀变遥感异常作为矿产资源综合评价与定位预测的主要参数，对在东天山戈壁地区的石英滩至赤湖地区3．3万余平方千米的范围内开展的ETM^ (TM)遥感勘察结果进行了蚀变异常提取，并依此进行了矿产资源快速评价与定位预测，还对部分异常点进行了实地查证。研究区内已知矿床、矿(化)点122个，遥感异常与其中105个互洽，吻合率86％，与已知矿床的吻合率为100％。经首批地面查证扩大了一处已知金矿点的找矿范围。 |

| Abstract: | With the remote sensing alteration anomalies as the major independent anomalies in evaluating mineral resources, this paper has discussed the ore-forming geological setting, described the information extraction technique from remote sensing alteration anomalies, evaluated and predicted mineral resources, and demonstrated the achievements made in identifying part of the remote alteration anomalies in a 33,000 km 2 area (from Shiyingtan to Chihu) of East Tianshan Mountains. 122 ore deposits and ore (mineralized) spots have been discovered in this area, of which 105 are coincident with the remote sensing alteration anomalies. The coincidence rate is 86%. It is especially prominent that the coincidence rate between the known ore deposits and the remote sensing alteration anomalies is 100%. The identification of the remote sensing alteration anomalies has led to the expansion of a mineralized area. |
