Structure-chemical formulae not only show the relative proportions of the various atoms in the composition of a mineral but also give information concerning its crystal structure. Many systems of notation have been devised, giving greater or lesser structural detail, including those by Hey (1950),...
Mineral - Crystal Structures, Chemical Compounds: The external morphology of a mineral is an expression of the fundamental internal architecture of a crystalline substance—i.e., its crystal structure. The crystal structure is the three-dimensional, regu
Many inorganic non-metallic materials consist of a variety of mineral compositions. Minerals aremonomersand compounds with a certain chemical components and structures. The mineral compositions are the key factors for the properties of somebuilding materials(such asnatural stone, inorganic gel and other...
Physical properties of minerals are the characteristics that can be observed or measured without changing the mineral’s chemical composition. These properties are based on the physical arrangement of atoms, the crystal structure, and the forces that hold the structure together. They help identify and...
One of the essential chemical properties of clay minerals is their cation exchange capacity (CEC). CEC specifies their ability to absorb positively charged ions or cations. The cation exchange capacity of clay minerals is dependent on the size of their crystal structure, the prevailing pH, the pr...

(i.e. Cu-Kα radiation). X-ray beams were directed to hit the sample such that process scatters the atoms in their path. Post scattering, structural characteristics of the sample were detected by applying Bragg’s law58. The presence of minerals in each sample was identified with the ...
This descriptive CMS classification is a binary system, addressing the ore body and the ore composition.The ore body is subdivided into the type of pegmatites (pseudopegmatite, metapegmatite, pegmatoid, pegmatite, and plutonic pegmatite), the shape and the structure of pegmatites, while the ...
