Evidence of the early stage weathering pedogenesis by carbonate rock

碳酸盐岩早期风化成土作用的证据

In the process of weathering and pedogenesis , there exists a phenomenon of differentiation by activation of special REE .

在风化和成土过程中，存在特殊稀土的活化分异现象。

The theory of corrosion - replacement pedogenesis of carbonate rock that has been put forward by authors was enriched further .

这一研究成果，进一步充实和完善了作者所提出的碳酸盐岩溶蚀&交代成土理论和学说。

Alternation of the pedogenesis on particle size is not significant . Coarse particles in the deposits can be used to indicate aeolian activity .

后期风化成壤作用对粒度改造作用不显著，剖面中粗颗粒含量变化可用来指示风沙活动历史。

The fine sands in the Onqin Daga Sandy Land may be in part caused by the pedogenesis occurring under the relatively humid conditions .

浑善达克沙地的沙粒较细在一定程度上也与该地区较湿润条件下的成土作用有关。
