15 صفحه اولClay mineralogy and surface charge characteristics of basaltic soils from Western Samoa
The clay mineralogy and surface charge characteristics of four basaltic soils from Western Samoa have been studied. The soils contained subordinate to dominant amounts of poorly ordered allophanic material in addition to varying amounts of crystalline free iron oxide minerals. Infrared studies revealed the presence of trace to subordinate amounts of kaolin minerals in all the soils. The surface...
متن کاملclay mineralogy of soils on quaternary sediment in northeast of urmia
introduction: minerals are one of the main components of soils which play different roles in the soils. minerals make up about 50% of the volume of most soils. they provide physical support for plants, and create the water- and air-filled pores that make plant growth possible. mineral weathering releases plant nutrients which are retained by other minerals through adsorption, cation exchange, a...
