SOIL MINERALOGY

1995
Recent studies of proto-imogolite, imogolite, allophanes with Si:Al molar ratios 1:2 and 1:1, proto-halloysite and hydrous feldspathoid and poorly crystalline aluminosilicates on weathered primary minerals were reviewed to contribute to understanding of poorly crystalline aluminosilicate clay minerals in soils and weathering products.

Soil Mineralogy and Elemental Composition

2011
Mineralogical analysis tells us what the soil is made of and charts the course of soil evolution through the processes of clay formation, accumulation, translocation and the destruction of minerals by weathering. We may consider the evolution of the varieties of chernozem, from the Calcareous to the Podzolized, as a sequence of weathering and leaching –

Geochemistry and Mineralogy of Manganese in Soils

1988
Manganese is about the tenth most abundant element in the earth’s upper continental crust with an average abundance of 650 mg kg-1 Mn. More than 250 minerals contain Mn as an essential constituent and several thousand minerals contain Mn as a minor substituent for essential structural ions such as Fe2+ and Mg2+.

Clay Mineralogy and Soil Structure

2015
Most civil engineering projects are built on soil or rock and are constructed solely or partly of these materials. This chapter provides engineers with a good knowledge of the type and characteristics of the terrain on which such projects are to be constructed in order to achieve optimum safety and economic performance.
