南秦岭东段下寒武统黑色岩系钒矿成矿地质背景浅析
Mineral Characteristics and Exploration Prospect of Vanadium Deposit of Lower Cambrian Black Rock Series in South Qinling East Segment
摘要
Abstract
The black rock series of Lower Cambrian in south Qinling are found in passive continental margin rift and depression basin of north Yangtze block, charactered by thick silicalite, carbonate-containing silicalite, claystone mingled with carbonatite and barite sheet. Vanadic mineral-bearing hydrothermal fluid migrating with control-basin growth fault is absorbed by claystone and provenance layers are formed. Owing to the consequent slipping thrust nappe from north to south in Indosinian to Yanshannian, ductile shear belt between basement and capping formation made metallogenic element of provenance layer actively migrate to accumulate mineralization. Basement uplift vinicities of Niushan, Fen-ghuangshan and Pingli are the most favorable points to prospect vanadium mine.关键词
