Types of chemical weathering reactions. 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. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Geological origin of clay clay is a mineral stew that is the result of the erosion of the earth s crust over vast spans of time.

Mineralogical and porosity data collected from the granite using a mineralogical map after chemical staining and scanning electron microscopy images combined with autoradiographs indicate that 1 the ferromagnesian rock forming minerals biotite and magnesiohornblende act as the main porosity source in the unaltered granite and 2 the nature of the clay minerals replacing rock. 3 at copperhead creek shooting club 7030 rr 1431 east in marble falls.
