福建平和植被覆盖区遥感地质构造异常信息提取及找矿预测

Extraction of remote sensing anomaly of geological structure and ore prediction in vegetation coverage in Fujian

福建平和地区构造发育强烈,植被覆盖率高,拥有良好的成矿地质背景。通过建立福建平和矾山地区三维遥感影像线环构造解译标志以及线环构造与成矿关系的分析,对研究区内典型线环构造进行了三维遥感解译,并总结了三维遥感线环构造解译标志,提高了线环解译的精度及准确性。在三维遥感线环构造解译的基础上,针对线环构造的特点进行了线性构造密度分析和线环交点密度的分析,实现遥感地质构造异常信息的提取与找矿应用。

Pinghe area in Fujian Province was characteristic of strong structure development, high vegetation coverage rate, fine oreforming geological backgrounds. Through establishment of 3D linear ring structure interpretation signs of remote sensing images for Pinghe in Fujian Province, and the analysis of relationship of the linear ring structure with mineralization, the authors established 3D remote sensing interpretation, summarized interpretation signs of 3D remote sensing, improved the precision and accuracy of linear ring interpretation in the research area. Based on the above interpretations, in terms of characteristics of linear ring structures, the density analyses of linear ring structures and node density of linear ring structures, the authors realized the extraction of remote sensing geological anomaly information and its application in ore prospecting.
