摘要
栾川白庙沟钼矿位于东秦岭钼成矿带东部,主要赋存于白庙沟岩体(γ53-4)及其接触带中。矿床具明显的面状矿化蚀变分带特征;矿化类型自下而上为斑点状、浸染状、细脉状;从下往上蚀变为钾化-黄铁绢云岩化-泥化-青磐岩化。本文通过对以往资料的分析整理,结合近期在该矿床详细地质编录的基础上,系统总结了成矿地质特征,建立了找矿模型,对比典型钼矿(东沟钼矿),白庙沟钼矿属于斑岩型钼矿床,本区成矿条件良好,具有形成中-大型斑岩型钼矿的潜力。
Baimiaogou molybdenum deposit in Luanchuan is located in the east of East Qinling molybdenum metallogenic belt.It is hosted mainly in Baimiaogou granite(γ53-4)and its contact zone of the later intrusive Heyu granite.The ore deposit has obvious plane mineralization alteration zoning features;the mineralization types include veinlet,disseminated and spotted from top to bottom;the alteration from the bottom to the top is successive albitization zone,pyrite-sericite zone,argillic alteration zone,and propylitic zone.By analyzing the previous studies,and considering recent detailed geological records of the deposit,the geological characteristics of mineralization are summarized systematically,the prospecting model is established.Baimiaogou molybdenum is a porphyry type molybdenum deposit when compared with the typical molybdenum deposit(Donggou molybdenum deposit).It is concluded that the ore-forming conditions in this area are good,and it has the potential to form medium-large scale porphyry molybdenum deposit.
