从TM图像中直接提取金矿化信息

Extracting Gold Mineralized Information Directly from TM Image

以内蒙古撰山子试区为例，阐明了“微差信息处理”的主要观点，基于这种认识直接ＭＴＭ图像中提取到的金矿化蚀变信息为撰山子金矿区及其外围找矿提供了丰富准确的指示性信息，取得了显著的经济效益和良好的社会效益。

As an example,a new method using TM image to gold mineral exploration in Zhuan-ShanZi area of Inner Mongolia is presented in this paper. The general view of this methodnamed “Micro-different informaiton processing”,is clarified. Based on the method,we havesuccessfully extracted the gold mineralization(alteration)information directly from TM im-age,which has provided a useful information for gold-ore exploration in ZhuanShanZi golddeposit and it’s surrounding. According to this information, five target areas are deter-mined. Field work has confirmed that all of the abnormal information in the TM image isrelated to gold mineralization (alteration)and 49.6-ton-calculating reserves as well 4.5- ton-industry-controlled reserves of gold have been detected in this work.It thus has pro-vided us a very good economic and social result.
