摘要
大卧龙地区位于夏日哈-什多龙铁-铅-锌-银-锡-钼-硅灰石-白云岩成矿亚带,是青海省铁多金属矿的主要成矿带之一。前人在矿床成因、控矿因素和找矿标志等方面研究较薄弱,如何在新一轮找矿中突破已成为目前矿床研究的关键问题。笔者在讨论成矿地质构造背景基础上,结合以往地质勘查成果资料,对矿(床)点地质特征进行了研究,分析成矿规律和控矿地质因素及矿区的找矿前景,认为在矿区热液型矿产找矿条件有利,受构造控制的(岩浆)热液型矿床为今后的找矿重点。
The Dawolong area is located in the Xiariha-Shiduolong Fe-Pb-Zn-Ag-Sn-Mo-wollastonite-dolomite metallogenic subzone,which is one of the main metallogenic belts of the iron polymetallic ore deposits in Qinghai Province.Less previous researches are focused on the genesis,ore-controlling factors and prospecting signs of these deposits.How to make breakthrough a new round of prospecting has become a key issue in current deposit research.Based on the discussion of the ore-forming geological structure background,the data of previous geological exploration has been systematically collected and studied,the geological characteristics of the mineral deposits(occurrences)have been studied,and the metallogenic regularity and ore-controlling geological factors and prospecting prospects of the mining area have been analyzed in this paper.It is considered that the prospecting conditions of the hydrothermal minerals in this mining area are favorable,and the structurally controlled(magma)hydrothermal deposits are the focus of future prospecting.
