vermiculation

The authors studied the characteristics of element geochemistry , mineral assemblage and microtexture of the white reticulate clay in the quaternary laterite of the dongting basin with some experimental analysis methods , such as chemical analysis , x - ray diffraction analysis , ir and sem analysis . the genesis of the vermiculate reticulate clay and the rhizomatic reticulate clay in the quaternary laterite of the dongting basin are discussed . the formation of crannies or holes in the soil and the transference of soil elements are absolutely necessary conditions to form the white reticulate clay in laterite 在野外考察的基礎上,運用化學全量分析x射線衍射分析紅外光譜分析和掃描電鏡微形貌分析等實驗方法和手段,對洞庭盆地第四系紅土地層中網紋的元素地球化學礦物組合特征和微形貌特征進行了系統研究,對洞庭盆地紅土地層中2種主要的網紋類型蠕蟲狀網紋和根狀網紋的成因進行了探討。

The formation of crannies of the vermiculate reticulate clay results from the stratigraphical pressure and the seasonal fluctuating of the groundwater level . the formation of holes of the rhizomatic reticulate clay results from the decomposition of the botanic roots 蠕蟲狀網紋孔隙空間的產生是由于地層靜壓力和地下水位季節性變化造成的,而根狀網紋的孔隙空間則是植物根系腐爛分解后提供的。
