摘要
红土型金矿是云南找金工作的主攻类型之一。云南新构造期运动是红土型金矿的主成矿期，地壳的快速抬升，古气候与古地貌的变化，表现出红土型风化壳剖面发育不全，成熟度低，厚度不大，对基岩含金性依存度高等特点。云南红土型金矿成矿作用为红土化作用的初、中期阶段，其金矿类型有岩控型、层控型和构控型三种。
Laterite gold deposits are the preferential type for gold exploration in Yunnan.The Neotectonic Period is the principal metallogenic period of laterite gold deposits in Yunnan. The rapid elevation of the crust and the changes of palaeoclimate and palaeogeomorph caused the incompletness,low maturity,small thickness and high dependence upon the gold bearing property of the bedrock etc of the laterite ptofile.The metallogenesis of laterite gold deposits took place at the initial or middle stages of laterization.Three types of deposit are devided:the rock controlled type,the strata bound type and the structure controlled type.
