摘要
综述了近年来网纹红土研究的事实成果,结果表明:网纹红土的强酸、富铝化特征明显;其形成是百万年以来的事,发育盛期在中更新世;其形成过程是先红土化,再网纹化,成因有风成和水成的说法;关于对网纹化机制、红土化是否仍在进行、网纹红土对古气候事件的指示意义等问题仍存在争议。
The studies of vermiculated red soil in recent years are summarized,The results show that the strong acid and laterized characteristics of vermiculated red soil are obvious; its formed time is in millions years, and the main period is in Middle Pleistocene; its formation includes laterite weathering and reticulation fon＇ning, and the causes of formation are considered of wind-cause and water- cause; but the questions such as the mechanism of reticulation forming, latcrization in present-day and the indication of vermiculated red soil for ancient environmental are on the debate.
