摘要
月亮坝砂金矿属小型冲积砂金矿床。该矿床的区域地质地貌控制矿床的空间分布位置、矿床规模及成因类型,微地貌控制矿体的产出形态及富集部位,除物质来源因素外,二者复合控矿作用是形成砂金矿床的主要条件。
Yueliangba gold deposit is a small scale alluvial gold deposit. Its spacial distribution, scale and genetic type are controlled by regional geology and geomorphology while the shape of the orebodies and the localition of concentration are controlled by local geomorphology or microrelief. Regional geomorphology and micro-relief play a composite role in ore-controlling processes in addition to the material sources, therefor both of them are preconditions of forming placer gold deposit.
