摘要
红土型金矿床是含金原岩在地表条件下经风化剥蚀、淋滤，基岩中的金产生活化迁移，在介质条件发生变化时金沉淀富集而形成的一类表生金矿床，其主要成矿条件有三个：①地理及气候条件；②大地构造条件；③源岩条件。
The Au deposit of laterite type is an epigenetic Au deposit formed by the precipitation and concentration in changed media of activated and removed Au of the Au-bearing original rock because of the weathering denudation and leaching under the surface condition. The main metallogenetic conditions of this type of Au deposit are: 1. geography and climate; 2.geotectonics; 3. original rocks.
