chemical weathering

基本解釋

The results show that the soils have, in varying degree inherited some properties of purple sedimentary rocks for their very weak chemical weathering.
結果顯示，紫色沉積巖發(fā)育的土壤，在一定程度上繼承了母巖的特點，化學風化作用微弱。
The variation of frequency curve's mode peak content with the increasing of depth, shows not only the trend of chemical weathering but also variation gradient of weathering extent.
頻率曲線眾數(shù)峰含量隨深度的變化，不但指示了化學風化趨勢，而且反映了風化程度的變化梯度。
And, in the maritime Antarctica, various modern periglacial processes play an important role in weathering, material transportation and soil formation. Besides, chemical weathering processes, incl…
闡述了本區(qū)內(nèi)化學風化的主要過程、機制與產(chǎn)物，同時指出生物因素在本區(qū)的巖石風化與原始土壤形成過程具有重要意義。

化學風化
We suggest that the felsic component rocks were dominant in the source area which has undergone middling chemical weathering. These sedimentary rocks were deposited in active continental margins.
它們具有巖石地球化學相似性,其源區(qū)物質(zhì)以長英質(zhì)巖石為主,中等化學風化程度,原巖沉積于活動大陸邊緣構造背景。

化學風化
We study the chemical weathering and its rate in the drainage basin,CO_2 consumption rate(volume) caused by chemical weathering of rocks,and the transport characteristics of inorganic carbon. Preliminary conclusions are presented as follow:1.
本文通過2007年6月和7月對黃河流域的水文地球化學特征以及干流河水中無機碳進行考察和研究,探討了黃河流域發(fā)生的主要化學風化反應、流域盆地的化學風化率、巖石化學風化的大氣CO_2消耗率(量),和無機碳的輸運特征。
