Weathering & Clay Minerals
Types of Chemical Weathering Reactions. Hydrolysis H + or OH-replaces an ion in the mineral. Example: Leaching ions are removed by dissolution into water. In the example above we say that the K + ion was leached.; Oxidation Since free oxygen (O 2) is more common near the Earth's surface, it may react with minerals to change the oxidation state of an ion.Онлайн-запрос

Feldspar, any of a group of aluminosilicate minerals that contain calcium, sodium, or potassium.Feldspars make up more than half of Earth’s crust, and professional literature about them constitutes a large percentage of the literature of mineralogy.. Of the more than 3,000 known mineral species, less than 0.1 percent make up the bulk of Earth’s crust and mantle.Онлайн-запрос

FORMATION AND OCCURRENCE OF CLAY MINERALS
process may be close: the last of the fluids and vapors of the magma may react with wall rock to form clay-mineral masses. This is probably the extreme of high-temperature, hypogene clay-mineral formation. Between this and the low temperature limit the transition is grad ual, the minerals formed falling into gradational groups.

2. The composition of clay materials | Geological Society
Clay materials are composed of solid, liquid and vapour phases. The solid phases are of mineral and organic phases that make up the framework of the clay materials. The mineralogy can be broadly subdivided into the clay and non-clay minerals, including poorly crystalline, so-called ‘amorphous’ inorganic phases. By definition, minerals are crystalline solids with well-ordered crystalОнлайн-запрос

On the one hand, some minerals become altered to other minerals. For example, feldspar is altered — by hydrolysis — to clay minerals. On the other hand, some minerals dissolve completely, and their components go into solution. For example, calcite (CaCO 3) is soluble in acidic solutions.
