摘要
云南省在喜马拉雅构造运动的影响下，新生代处于强烈而快速的抬升期，古气候、古地貌变化大，与之相关的红土型金矿的成矿条件和成矿作用呈现出许多特殊性，表现出风化剖面完整度差、成熟度低、厚度较薄以及对基岩含金建造依存度高等特点。云南红土型金矿分岩控、层控和构控三种类型，风化剖面多呈五层结构，矿床规模与风化壳规模呈正消长关系。
During Cenozoic era, affected by the Himalaya orogeny, Yunnan was elevated intensively and rapidly, and its paleoclimate and paleogeography have tremendously changed. However, the metallogenic conditions and mineralization of the related lateritic gold deposits emerge many particularities. Its weathering sections are characterized by thin thickness, bad integrity, low maturity and high dependant on the goldbearing formation of bedrock, and can be mainly divided into five layers. The lateritic gold deposits in Yunnan Province can be divided into three types: rock controlled, stratabound and structural contolled. The sizes between the deposits and the weathering crusts are positive correlation.
