Granite Hydrolysis Weathering

This reaction is called hydrolysis.

Granite hydrolysis weathering.

Hydrolysis occurs for example when water comes in contact with granite. From the site of pamela gore georgia perimeter college first unweathered granite contains these minerals. O na plagioclase feldspar o k feldspar o quartz o lesser amounts of biotite amphibole or muscovite the feldspars will undergo hydrolysis to form kaolinite clay and na and k ions the na and k ions will be removed through leaching. Chemical weathering occurs when water dissolves minerals in a rock producing new compounds.

Hydrolysis is the chemical weathering of minerals by a mildly acidic water that forms when rains dissolves trace gases in the atmosphere. The most common example of hydrolysis is feldspar in granite rocks. Feldspar crystals inside the granite react chemically forming clay minerals. Hydrolysis occurs for example when water comes in contact with granite.

There are different types of chemical weathering. Chemical weathering occurs when water dissolves minerals in a rock producing new compounds. Feldspar crystals inside the granite react chemically forming clay minerals. 14 15 as demonstrated in the following reaction this causes potassium feldspar to form kaolinite with potassium ions bicarbonate and silica in solution as byproducts.

The reaction of feldspar minerals in granite with rainwater produces kaolinite white clay known as china clay used in the production of porcelain paper and glass. This reaction is called hydrolysis. What happens when granite is weathered. Chemical weathering of granite occurs when dilute carbonic acid and other acids present in rain and soil waters alter feldspar in a process called hydrolysis.
