甘肃省肃北蒙古族自治县七角井钒矿矿床地质特征及找矿方向

Geological characteristics and prospecting direction of Qijiaojing vanadium deposit in Subei Mongolian Autonomous County,Gansu Province

七角井钒矿矿体赋存在寒武系西双鹰山组的碳质板岩中,矿区碳质板岩是主要的含矿岩。钒矿床是形成于陆缘湾(海)盆-浅海环境的沉积变质型钒矿床,形成于陆缘海湾(海盆)-浅海环境。矿石结构以晶粒结构、碎裂结构和交代结构为主,矿石构造以浸染状、脉状和条带状构造为主。本文重点讨论该矿床的地质特征、矿床成因、找矿标志及找矿方向。

The Qijiaojing vanadium orebody occurs in the carbonaceous slate of the Cambrian Xishuangyingshan formation,and the carbonaceous slate in the mining area is the main ore-bearing rock.The vanadium deposit is a sedimentary metamorphic vanadium deposit formed in the continental margin bay(sea)basin-shallow sea environment and formed in the continental margin bay(sea basin)-shallow sea environment.The ore structure is mainly grain structure,cataclastic structure and metasomatism structure,and the ore structure is mainly disseminated,vein and banded structure.This paper focuses on the geological characteristics,genesis,prospecting criteria and prospecting direction of the deposit.
