鄂东南金属矿区立体地质填图中的物探工作

GEOPHYSICAL PROSPECTING WORK IN STEREOSCOPIC GEOLOGICAL MAPPING OF THE SOUTHEASTERN HUBEI METALLIC ORE DISTRICT

本文介绍了鄂东南金属矿区－阳新岩体西北段立体地质填图中的物探工作方法及其地质找矿成果。物探与地质密切配合，运用重力、磁测、电测深等综合方法，在研究岩体结构和形态，圈定控矿构造，成矿预测等方面取得了一系列新认识。立体地质图形象地显示了阳新岩体的空间地质特征。找矿靶区验证结果表明，物探在立体地质填图中应用效果好，成矿预测准确。

The present paper describes the geopbysical prospecting method used in stereoscopic geological mapping of the Southeastern Hubei metallic ore district (the northwestern part of the Yangxinrock mass) and the geological ore-prospecting achievements thus gained. Through close coordination of geophy-sical and geological work and using integrated methods including gravity survey, magnetic survey and electrical sounding, the author obtained a series of new understanding in such aspects as the study of the structure and scape of the rock mass, the delineation of the ore-control structure and shape of the rock mass, the delineation of the ore-control structure and the ore prognosis. The stereoscopic geological map vividly exhibits the spatial geological characteristics of the Yangxin rock mass.The test on the ore-prospecting target area has demonstrated that geophysical prospecting is quite effective in stereoscopic geological mapping and can lead to accurate metallogenic prognosis.
