5.2 Chemical Weathering | Physical Geology

The hydrolysis of feldspar can be written like this: CaAl 2 Si 2 O 8 + H 2 CO 3 + ½O 2 —-> Al 2 Si 2 O 5 (OH) 4 + Ca 2+ + CO 3 2-plagioclase + carbonic acid —-> kaolinite + dissolved calcium + carbonate ions. This reaction shows calcium plagioclase feldspar, but similar reactions could also be written for sodium or potassium feldspars.

5.3: Sedimentary Rocks

 · This biochemical extraction and secretion is the main process for forming limestone, the most commonly occurring, non-clastic sedimentary rock. Limestone is mostly made of calcite (CaCO 3) and sometimes includes dolomite (CaMgCO 3), a close relative. Solid calcite reacts with hydrochloric acid by effervescing or fizzing.

Sandstones comprise about 20% of all sedimentary rocks and are formed in a variety of different environments including fluvial (rivers), marine, coastal (oceans and beaches), aeolian (wind blown), and glacial (ice).

Weathering

Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.Weathering occurs in situ (on site, with little or no movement), and should not be confused with erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity.

What Hornfels Is and How It Forms

 · Carbonate hornfels is often banded, sometimes with pelitic (biotite) hornfels. Carbonate hornfels is stronger and tougher than limestone. Mafic hornfels: Mafic hornfels result from heating of igneous rocks, such as basalt, andesite, and diabase. These rocks exhibit varied compositions, but consist mainly of feldspar, hornblende, and pyroxene.

It does not matter by what process you metamorphose quartz sandstone and limestone, their composition does not change, and they produce the same kind of metamorphic rock.

The release of K from feldspars through weathering reactions is an important process in replenishing the labile pool of soil K.

Reading: Characteristics of Sedimentary Rocks | Geology

Although feldspar is a fairly hard mineral, it does cleave (split apart) and is chemically reactive, especially in the presence of water. The most abundant product of chemical reaction of feldspar and water is clay minerals. During the erosion-to-deposition process, clastic sediments lose feldspar and gain a larger proportion of clay.
