A Comparative Study of the Properties of Mica in Rhizosphere and Bulk Soil Under Different Plant Covering. [PDF]
Results of x-ray diffractions for Bulk soil, represented by the horizontal distance 50H, show the presence of low-crystalline chlorite, smectite and regular interstratified chlorite- smectite in soil under Citrus aurantium trees.

K-Ar dating by smectite extracted from bentonite formations [PDF]
We attempt to apply K-Ar dating to extracted smectite from bentonite formations collected by different age formations from Japan, China, and America. The results show that the K-Ar ages of smectite are younger than the expected geological age estimated ...

T-2 toxin adsorption by hectorite [PDF]
The adsorption of T-2 toxin by the natural smectite mineral-hectorite at pH 3.0, 7.0 and 9.0 was investigated. The results of T-2 toxin adsorption on hectorite showed that the T-2 adsorption capacity decreased with increasing concentration of adsorbent ...
