摘　　要：针对东黑刺沟矿区,详细介绍了基于TM数据定量提取蚀变信息的方法、内容及实施步骤,指出此方法应用时需要注意的问题。该方法包括数据检查评价、干扰去除(或称掩膜)、遥感异常的圈定及分级3部分。通过对遥感异常信息进行数理统计,定量化分析,增强了矿化蚀变异常,指出了有用遥感异常找矿区段。结合实际地质概况及矿化信息,验证了本次工作的可靠性。Aiming at eastern Heicigou mining area, the quantitative extraction method of alteration information based on TM data and its practical steps are introduced in detail. Some problems which should be paid attendtion to are pointed out as well. The method includes three steps, namely, data-inspection-evaluation, interference deletion （ or masking technique） , the delineation and grading of remote sensing anomaly. The method enhances the anomaly of mineralization alteration by mathematical statistics and quantitative analysis. And the ore-prospecting areas are indicated. The reliability of this method has been verified by the combination of the geological outline and mineralization information.
