川西可尔因矿集区稀有金属矿床成矿规律与找矿方向
|
摘要
为了解可尔因矿集区地质特征和成矿规律,查明矿集区地质找矿方向,对矿集区内成矿地质条件进行了系统分析和总结。研究表明稀有金属成矿主要与印支晚期—燕山早期的中-酸性花岗岩有关,岩浆侵位与成矿伟晶岩脉之间具有结晶分异演化关系。含矿岩浆不均一的结晶分异作用,导致了稀有金属矿化多分布在可尔因岩体东部和南部。在过铝质高挥发分的钙碱性-高钾钙碱性岩浆侵位和结晶分异演化过程中,在岩体与地层的接触带构造发育地段,形成了伟晶岩型稀有金属矿体,具有"岩浆岩-地层-构造"控制成矿的特征。据此提出了矿集区内的找矿标志和岩体与地层接触部位为今后找矿重点区域。
In order to understand the geological characteristics and metallogenic regularity of the Keeryin ore deposit,the authors determined the geological prospecting direction of the ore concentrating area, and systematically analyzed and summarized the metallogenic geological conditions. It is believed that the rare metal mineralization mainly occurred in the late Indosinian-Yanshanian period. The relationship between magmatic emplacement and mineralized pegmatite dykes is characterized by crystal differentiation and evolution. The inhomogeneous crystallization differentiation of ore-bearing magma resulted in the distribution of rare metal mineralization in the eastern and southern Koln intrusion. In the process of emplacement and crystallization differentiation of calc-alkaline-high potassium calc-alkaline magma with high volatility, a pegmatite-type rare metal orebody was formed in the contact zone between the rock mass and the strata. It has the characteristics of"magmatic rockstratigraphy-structure"to control mineralization. Based on the above research, the authors put forward the oreprospecting indicators and pointed out that the contact zone between rock mass and strata is the key ore-prospecting area in the future.
