| 摘 要： | 滇西兰坪－思茅盆地含铜（多金属）菱铁矿床产于中￣晚三叠世裂陷槽内，含矿地层岩性为大路边组（Ｔ３ｄ）或三合硐组（Ｔ３ｓ）含火山碎屑岩、凝灰岩的碳酸盐岩建造，成矿与海底中￣低温热水活动密切相关，受同生断裂和海底洼地控制。根据成矿地质背景、矿体产状、矿石组构、热水沉积岩、围岩蚀变及地球化学异常，论证了矿床的热水沉积成因。

| Abstract: | Copper(polymetal)-bearing siderite deposits in Lanping-Simao basin occured in middle late Triassic taphrogens.Their ore-bearing strata,which contained more or less pyroclastic rocks or tuffs,were carbonatite beds of Dalubiam(T3d)or Sanhedong(T3s)Formation in horizon.The mineralization related closely to activity of middle-low temperature submarine hot brine,and was controlled by contemporaneous faults and submarine depressions.This paper mainly discusses the hydrothermal sedimentary evidences of the deposits in the light of geological settings,ore occurence and fabrics,exhalites,wall-rock alteration and element geochemical characteristics. |
