| 摘 要： | 老营坪岩金矿床位于老营坪断层次级层间破碎带内,赋矿地层为泥盆系危关群中部岩组;矿体呈似层状;矿石分为氧化和原生矿石;围岩蚀变有褐铁矿化、黄铁矿化、毒砂化、碳酸盐化、硅化、绢云母化等。成矿热液类型为地下热卤水型;老营坪断层次级层间破碎带为主要控矿构造。矿床系浅成低温热液微细浸染型金矿床;成矿模式:地表水、地下水受热源影响形成热液循环,运移过程中萃取矿质形成成矿热液,在有利构造部位沉淀成矿。

| Abstract: | The Laoyingping Au deposit is confined to the middle of the Devonian Weiguan Group.The stratoid orebodies occur in secondary intraformational ruptured zone of the Laoyingping fault.The wallrock alteration are limonitization, pyritization, arsinopyritization, carbonation, silicification and sericitization.The ore fluids were a hot brine.The Au deposit is an epithermal fine-disseminated one.The deposit was formed by cycle of the hot brine with extracting ore material and discharge in favorable structural site... |
