kaolinization मीनिंग इन हिंदी

The mineral deposits are found within heavily altered breccias and porphyries in the case of Cerro Choquelimpie, with kaolinization and silification predominant.
They are powerful agents in attacking the minerals of the rocks which they traverse, and instances of their operation are found in the kaolinization of granites, ore deposits.
A large number of the finer quartz-porphyries are also in some degree silicified of impregnated by quartz, chalcedony and opal, derived from the silica set free by decomposition ( kaolinization ) of the original feldspar.
