作者高云峰（2019）在《南秦岭镇安西部典型钨矿区控矿构造特征与成矿模式》一文中研究指出：镇安西部钨矿集区位于秦岭中央复合造山带南秦岭构造带内,具体为南秦岭造山带印支期近东西向滑脱-推覆带与燕山期北北东向陆内造山带南秦岭石泉-汉阴牛山-小磨岭北东向构造岩浆带交汇的构造结合部位。镇安西部钨钼金多金属成矿带是近年来陕西省地勘基金项目资助下新发现和勘查评价获得的一个新区,成矿地质条件优越。近年来随着各地勘单位及矿业公司的持续深化调研分析,陆续发现了金盆、东阳、棋盘沟、杨沟、桂林沟、月河坪、核桃坪等一批大中型钨矿、钨钼矿、钼金矿。但前人对该地区找矿勘查成果梳理集成不够,缺乏整体、系统评价研究,尤其对该区钨钼金矿成矿时代、地质背景、控矿构造、与成矿有关的侵入岩体及成矿模式等研究较少,在一定程度上制约了该区钨钼矿深化研究和进一步找矿预测工作。因此,根据该区现有钨钼矿成特征及其与岩浆岩成矿关系,在现有勘查评价阶段,对该区钨钼矿控矿构造的研究尤为重要,其不仅可以为研究区找矿勘探提供科学依据,同时也为南秦岭成矿带构造-岩浆-成矿演化研究提供重要资料。本文主要通过对矿集区棋盘沟、核桃坪等典型钨矿床进行野外调查及室内研究,总结矿床特征、成矿规律、控矿构造样式、找矿预测标志,结合前人研究成果,提出该区控矿构造新认识、归纳总结该区成矿规律建立该区钨钼矿成矿模式,并取得以下认识:(1)矿集区内控矿构造为近东西向与北东-北北东向两组不同方向的构造裂隙。(2)根据该区构造背景知,矿集区内北东-北北东的构造裂隙是晚印支-燕山期构造活动形成,近东西向的构造裂隙则主要是印支期构造活动形成的,相对于燕山期钨钼成矿期近东西向断裂为成矿前构造,而北东-北北东向断裂裂隙属于成矿期构造。(3)矿集区内钨矿化类型主要以热液石英脉型及断控矽卡岩型为主,其中石英脉型主要受北东-北北东向断裂及节理裂隙控制,少量受近东西向断裂控制;断控矽卡岩型主要受近东西向断裂破碎带控制。(4)通过对矿集区棋盘沟钨矿区及东阳钨矿区含钨石英脉中流体包裹体的研究分析认为成矿热液顺北北东向构造裂隙上升形成石英脉白钨矿,在运移过程中温度不断降低,之后又沿近东西向构造裂隙灌入形成断控矽卡岩型白钨矿。(5)区内典型矿床辉钼矿Re-Os测年显示,成矿时代在196.3±3.3Ma~199.7±3.9Ma,属早侏罗世,成矿时代为燕山早期。
