NG：沉积岩容矿Cu-Pb-Zn矿床受控于克拉通边缘稳定性（图）
NG 沉积岩 Cu-Pb-Zn矿 稳定性
2020/8/26
贱金属是指除了金、银、铂等贵金属之外其它的所有金属，如铁、铜、铅、锌、镍、铝、锡和钨等。沉积岩容矿贱金属矿床由于储量大（相对于火山块状硫化物矿床）、品位高（相对于斑岩铜矿），并且开采过程中环境污染小，适应社会可持续发展和向清洁能源经济过渡的需求，但现有矿产资源的开采速度已经超过了新矿床发现的资源量。为了扭转这种态势，必须大幅度提高矿床勘查的成功率，尤其是找寻那些埋藏在沉积物或冰层等浅覆盖物之下的矿...
内蒙古霍各乞大型Cu-Pb-Zn矿床地处内蒙西部狼山地区，为狼山-渣尔泰山成矿带的典型矿床。前人依据该矿裂谷沉积赋矿、岩性控矿、具有层状矿体等宏观特征判断其为裂谷环境下形成的热水沉积矿床，但也有部分学者提出其为受构造控制的后生热液矿床。本次研究以岩矿相学观察为基础，结合热力学模拟，提出该矿为受剪切带控制的变质热液矿床。矿区内赋矿围岩普遍经历角闪岩相区域变质作用及韧性剪切变形。宏观上，矿体与矿区内剪...
