山东招远一掖县地区采金历史悠久,金矿点星罗棋布,近年来不断发现新矿点,潜力很大。为了深入研究招—掖地区构造控矿因素,笔者利用美国陆地卫星彩色图像,局部利用1:1.6万彩红外航片,对该地区进行多层次遥感地质解译,综合对比地质、物、化探资料,圈定了穹窿构造和发育在穹窿构造两边缘的三个多边形构造。初步查明了金矿类型、分布规律与多边形构造的关系,建立了该区遥感影像找金标志,具有一定的实际意义。一、区域地质概况该区位于胶东古陆西北部,郯庐断裂以东、莱阳
Shandong Ziyuan Yedian County area has a long history of gold mining, gold dotted with points, in recent years continue to find new mine points, great potential. In order to further study the tectonic ore-controlling factors in Zhaoye-Yye region, the author utilizes the US terrestrial satellite color image and partially utilizes the 1: 1.6 million color infrared video to conduct multi-level remote sensing geologic interpretation in the area. The comprehensive comparison of geology, Information, delineated the dome structure and development in the dome two edges of the structure of three polygons. The relationship between the type and distribution of gold deposits and the polygon structure has been tentatively identified, and the gold sign for the remote sensing image has been established in this area, which has some practical significance. First, the regional geological overview The area is located in the northwestern Jiaodong ancient land, east of Tanlu fault, Laiyang
