| 摘 要： | 房圪垃湾铅矿床产于太古宇太华群由角闪斜长片麻岩、黑云斜长片麻岩等组成的一套中深程度的区域变质岩中.区内主要有F9-Ⅰ、F9-Ⅱ、F9-Ⅲ、F10-Ⅰ、F10-Ⅱ、F11-Ⅰ、Ⅰ号等7个矿体，均赋存于断裂破碎蚀变带内，并严格受其控制.矿体的形态、产状与含矿断裂带基本一致，矿体多呈薄脉状、透镜状或似层状，沿走向及倾向均具舒缓波状特征，膨缩及分支复合现象明显.通过研究地质特征，认为矿床类型为破碎带蚀变岩型矿床，属中低温热液成因，成矿作用为区域变质-混合岩化-岩脉侵入-中低温热液交代充填.

| Abstract: | The Fanggelawan lead deposit, occurring in the amphibolite plagioclase gneiss and biotite plagioclase gneiss of Archean Taihua group consists of seven ore bodies, which are hosted and strictly controlled in the fractured alteration zone. The morphology and attitude of the orebodies are basically in accord with those of the fault zone. The ore bodies are in veinlet, lenticular or stratoid, with obvious expansion, contraction, branching and merging. Study on its geological characteristics shows that the deposit is of fracture zone altered rock type, belonging to meso-epithermal fluid genesis. The metallogenic process experienced regional metamorphism-migmatization-dike intrusion-meso-epithermal fluid replacement and filling. |
