摘要
利用已有资料,进行遥感图像数字图像处理,将遥感图像与化探数据进行融合,再结合地质资料,经过将遥感、化探与地质信息的综合分析,总结出保山—耿马成矿带东段矿体,是赋存在三叠系顶部与上第三系底部的沉积不整合接触带上或赋存在变砂岩地层的层间破碎带中,锡矿化体的分布明显受该区北西向的区域构造控制,矿化与花岗岩体关系密切,在岩体与地层接触带上具有矿化强烈的成矿地质特征,从而缩小了探矿靶区。经野外踏勘,圈定了成矿有利地段。
The authors make full use of the past data and has the data coordinated and synthesized before field work. First, the digital image processing for the remote sensing data is done and remote sensing data is combined with geochemical surveying data, and then with the geological data. Through the synthetic analyses of the three, the creating states and geological characters of the mineral of Baoshan-Gengma mineral zone is summarized. The ore bodies are contained in the unconformable contacted zone of upper Triassic and lower Tertiary or the rubble zone between the stratums of metamorphosed sandstone. They are obviously controlled by the Northwest structures of the area and have a close connection with granite because the mineralization becomes stronger between the contacted zone of granite and stratum. Through field work, the ore exploration targets were ascertained and a good result is obtained.
