It is called Leaching
CARBONATION process by which dissolved carbon dioxide in rainwater or moisture in surrounding air forms carbonic acid and reacts with the minerals in the rock. This process weakens the rock thus breaking it down in the process.e.g.: Calcium Carbonate + Water + Carbon Dioxide --->Calcium Carbonate (soluble)HYDROLYSISchemical reaction between the minerals in the rock and hydrogen in rain water. For example, during hydrolysis, the feldspar in granite changes to claymineral which crumbles easily, weakening the rock and causing it to break down.OXIDATION The process by which oxygen combine with water and minerals in the rock such as calcium and magnesium. When iron reacts with oxygen, reddish -brown iron oxide is formed. The iron-oxide crust crumbles easily and weakens the rock.e.g. : Iron + Oxygen --> Iron Oxide (crumbles)SOLUTIONprocess by which minerals in the rocks dissolve directly in water.HYDRATION process where minerals in the rock absorb water and expand, creating stress which causes the disintegration of rocks.
Fractional Crystallization
Fluorescence occurs when a substance has absorbed light and later emits that light. Quartz is a material that undergoes this process. Minerals and creatures can both exhibit fluorescence.
I believe the process is called firing, some clays require temperatures of close to 2500 degrees F, other clays it takes much less heat depending on the minerals in the clay.
Partial melting occurs in rocks because the different minerals that compose rocks have different melting points. For example, felsic minerals (e.g. quartz and feldspar) melt at around 700 degrees Celsius while mafic minerals (e.g. pyroxene and olivine) melt at around 1200 degrees Celsius. Therefore, felsic minerals will melt first leaving the mafic minerals solid.Fractional crystallization occurs when minerals from a magma cool and crystallize out of the magma. The first crystals to melt in partial melting will be the first minerals to crystallize out when the magma begins to cool. Therefore, mafic minerals will crystallize first, followed by felsic minerals.Both partial melting and fractional crystallisation tend to produce a more felsic magma than their source rocks.The difference is simply that they are the reverse of one another, heat it up, cool it down. Things that melt first solidify last and separate from one another.
