河南省栾川县石瑶沟钼矿地质特征及找矿方向
Geological characteristics and ore-searching direction in Shiyaogou molybdenum deposit in Luanchuan county, Henan province
摘要
Abstract
The Shiyaogou deposit is a large molybdenum deposit newly discovered in the East Qinling molybdenum belt. In the mineralization area are developed Au, Pb, Mo, Ag anomalies and scheelite, bis-mutite and native gold heavy mineral anomalies in river sediments. Mo mineralization emplaces at intersection of the EW-trending Machaoying fault and the NE-trending Jiaoyuan fault. Granoporphyry and the host rock-Xionger group with Mo mineralization are all intersected to depth. In plan the Mo mineralization body is elliptical pods with length of 1 050 m, width of 450 m and thickness of 202~l 071 m. The grade is w(Mo)=0. 030%～1. 30%, averagely 0. 06%. Areal wallrock alteration occurs in zonation. Silicifica-tion and feldsparization are closely related to mineralization. Genetically, the Shiyaogou deposit is porphyry type Mo deposit. Further exploration should be targeted to intersections of EW-trending and NE-trending fault in the area.关键词
