摘要
澳大利亚伊尔冈地块内红土型金矿化形成的古气候条件为季节性潮湿热带气候、干旱气候和持续干旱气候．Ａｕ在不同的气候条件下发生了活化—沉淀—再活化—再沉淀作用．表生金矿化可见于红土化剖面的红土带、腐泥土带中和运积盖层之下．
Lateritic type gold deposit,with its unique genesis and important economic significance,has interested geologists and metallurgists The paper presents the climate condition for lateritic gold mineralization,the mechanism of gold remobilization and the implication for exploration in Yilgarn Block of Western Australia
