本文主要研究内容
作者尹大胜,方维萱,郭玉乾（2019）在《云南东川铜矿田面山—四棵树成矿带裂隙构造控矿规律》一文中研究指出：云南东川铜矿田位于扬子板块西缘川滇铜多金属成矿带。东川铜矿区内面山—四棵树成矿带裂隙构造叠加成矿-控矿作用明显,但对其研究较薄弱。在对面山—四棵树成矿带坑道进行构造岩相学综合编录的基础上,结合区域地质背景,对典型中段的铜矿体进行裂隙要素测量,制作玫瑰花图进行分析并对岩相进行分带。研究表明:①面山—四棵树成矿带碱性铁质基性岩浆沿大角度切层断层侵入落雪组,由于岩浆的侵入挤压作用,侵入岩体与地层的接触带由内向外根据岩石变形程度可分为片理化相带→热液角砾岩相带→碎裂岩相带,其中,碎裂岩相带根据岩石碎裂程度由内向外可划分为强碎裂岩相带→碎裂岩相带→弱碎裂岩相带,铜矿品位也随之由高变低;②裂隙岩相学研究揭示主要存在3组含矿裂隙,走向分别为近EW向、近SN向和NEE向,其中近EW向裂隙(与地层产状基本一致)为最主要的含矿裂隙;③多期次的构造活动使岩石中裂隙发育程度高且交切关系复杂,以岩浆侵入改造成矿期为依据可将裂隙分为成矿前裂隙、成矿期裂隙和成矿后裂隙。通过对岩浆侵入-裂隙构造系统特征与成矿-控矿规律的研究,认为面山—四棵树成矿带侵入岩体附近的铜矿体受岩浆-裂隙构造系统改造富集作用明显,基性岩体附近碎裂岩相带为形成较高品位"裂隙矿"的有利靶区。
