| 摘 要： | 我国南方自新第三纪以来出现炎热潮湿的气候,此时是地洼余动期,地壳活动性渐趋减弱,在某些相对稳定又缓慢上升的块断区中,当基岩为中性和基性的火成岩、正长岩、灰岩以及某些花岗岩类时,有可能形成三水型铝土矿。有利的找矿区域是东南沿海和云贵高原南部。

| Abstract: | In some block-fault regions of South China, where crustal movement weakened
gradually and stabilized relatively and terrene ascended slowly during diwa
residual-mobility period, intermediate and basic igneous rock, alkaline rock, limestone
and some granitic rock can be weathered and transformed probably into gibbsitic
deposits since Neogene period when the climate is scorching hot and damp. The
favourable zones for looking for the deposits are the southeast coastal provinces;
and the southern part of Yunnanguizhou Plateau, |
