地、物、化综合方法在豫西小河岩体南缘找矿中的应用
The application of the integrated geological, geophysical and geochemical methods to ore-prospecting at the southern edge of Xiaohe rock body in western Henan Province
摘要
Abstract
In order to study the ore-potential of the area around the Xiaohe rock body in southern Xiaoqinling,the authors chose 1 ∶50 000 8-Yi 3AgWBi stream sediment anomaly,Meso-Proterozoic Xiaohe rock body and F1 fault at the contact zone of Meso-Proterozoic Buandaokou Group to conduct geological,geophysical and geochemical integrated exploration.Soil survey led to the discovery of the Zhangjikou 1-Jia 3 Ag Au Sb Zn Pb As Co Cu Mo B composite anomaly characterized by relatively good element combination,large anomaly area and high intensity,in which the highest value of Ag is higher than 20× l0-6,with distinct three-grade concentration zoning and relatively strong concentration center;IP sounding predicted that F1 fault extends downward,surface trenching discovered a silver orebody at 1-Jia 3 anomaly in F1 structural alteration zone,and drilling revealed the existence of a thick and large Ag-Pb-Zn orebody.The discovery of this ore deposit has realized the ore-prospecting breakthrough at the southern edge of Xiaohe rock body,and also serves as a typical example of the application of the geological,geophysical and geochemical integrated exploration.关键词
