莱州南部地区黄金资源遥感勘探

REMOTE SENSING FOR EXPLORATION OF GOLD RESOURCES IN THE SOUTH OF LAIZHOU CITY

用陆地卫星ＴＭ数据制作遥感影象图，在遥感影象图上识别旋扭构造．建立旋扭构造的数学模型，用已知金矿矿脉、岩脉、断裂、河流为控制点，用旋扭构造的数学模型绘制旋扭构造的旋回面（断裂破碎带），即预测的金矿矿脉．再用地质资料的钾化、绢英岩化、黄铁矿化等金矿围岩蚀现象和地面调查资料验证，为化探、槽探、钻探作准备．

emote sensing image was made using Landsat-5 TM data. The vortex structure was interpreted on the remote sensing image. The mathematics model of vortex structure was established. The vein of the gold ore,vein of rock,fault and river given by geological map, mineral map and geographic map were used as control points.The mathematics model of vortex structure was used to draw the vortical surfaces of vortex struture or faulting tectomoclastic rock belts. The geological data such as well rock alteration - reddening, silicification, sericitization, pyritization were used to verify the existance of the faulting belts and of the veins of gold ore, to prepare for chemical exploration,digging and drilling.
