Características mineralógicas de la fracción inferior A 2$ en vitrandepts (IV)
The mineralogical composition of the clay fraction ($2u) of four soil profiles from Zahagu, Tajanara, Chio. Chinyero, have been studied by X-ray diffraction and I. R. absorption techniques. This clay fraction contains a great amount of amorphous gels and some kaolin-type minerals (hallosyte and disordered kaolinite, probably in a transformation stage), they also contain allophane and illite. Primary minerals present in the clay fraction of the four profiles are felspars and piroxenes. Quartz and a-crystohallite are also founds in the clay fraction in some soil horizons.

| Summary: | The mineralogical composition of the clay fraction ($2u) of four soil profiles from Zahagu, Tajanara, Chio. Chinyero, have been studied by X-ray diffraction and I. R. absorption techniques. This clay fraction contains a great amount of amorphous gels and some kaolin-type minerals (hallosyte and disordered kaolinite, probably in a transformation stage), they also contain allophane and illite.
Primary minerals present in the clay fraction of the four profiles are felspars and piroxenes.
Quartz and a-crystohallite are also founds in the clay fraction in some soil horizons. |
