Minerals hydrous mineral

Bound in minerals such as uraninite, pitchblende, coffinite, etc. fixed as a replacement ion for Y, Ce, Zr, Th, Ca, and Ba in other, particularly accessory minerals and adsorbed as ion on clay minerals, hydrous iron oxides, etc.

Landsat imagery was downloaded from the GloVis viewer (http //glovis.usgs.gov/). The data were atmospherically and geometrically corrected. Band ratios were used to map the presence of iron oxides, hydroxides, and hydrous minerals, possibly associated with porphyry-style hydrothermally altered and mineralized rocks.

Ion microprobe analyses of hydrous minerals in Martian meteorites reveal two different sources of hydrogen. One is interpreted as magmatic water, with 5D = 900 permil, and thought to reflect the mantle composition the other is thought to reflect the atmospheric composition, with 5D =4000 permil (Leshin, 2000). The incorporation of atmospheric water into these meteorites suggests some kind of cycling of water between the atmosphere and lithosphere on Mars. 

Only a fraction of the total metal content of soils and sediments tends to be available for uptake by plants or biota. This fraction is generally associated with the colloidal material (i.e., clay minerals, hydrous oxides and organic matter), but views differ on the relative effects of the individual components.

Isomorphic substitution is especially significant in the case of clay minerals (hydrous aluminum silicates), which are formed by the weathering of the primary silicates of igneous rocks. Most of the clay minerals belong to the phyllosilicates, but there are some that are of fibrous and amorphous structure. 

Thermodynamic analysis of mineral equilibria was first made by us (Mel nik and Siroshtan, 1973) on the basis of the new system of thermodynamic constants of minerals that is consistent with experiments (Mel nik, 1972b), which also includes important hydrous minerals like grunerite and minnesotaite. These data were subsequently amended (Mel nik and Radchuk, 1977b), and supplemented by the thermodynamic constants of greenalite and of some diagenetic iron and magnesium minerals (see Appendix).
