化探数据K－L变换图像分析及其在金矿成矿规律研究中的应用

KL TRANSFORM IMAGE PROCESSING OF GEOCHEMICAL EXPLORATION DATA AND ITS APPLICATION IN THE STUDY OF METALLOGENIC REGULARITY OF GOLD DEPOSIT

Ｋ－Ｌ变换是遥感数字图像处理中常用的方法之一。文中用Ｋ－Ｌ变换图像分析的方法对冀北区域化探数据进行再分析，提取出张家口—赤城金矿化集中区金矿成矿期次的信息，并用数字图像复合分析的方法探讨了各成矿期在空间上的发育情况。

KL transform image processing ,which is one of the general methods used in remotely sensed digital image processing, has been used to restudy regional geochemical exploration data in ZhangjiakouChicheng region,northern Hebei. The informations about mineralization epoch of gold deposit and its development in the region have been got
