Granite Hydrolysis Weathering

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.

Granite hydrolysis weathering.

There are different types of chemical weathering. What happens when granite is weathered. From the site of pamela gore georgia perimeter college first unweathered granite contains these minerals. The clay weakens the rock making it more likely to break.

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. This reaction is called hydrolysis. Hydrolysis occurs for example when water comes in contact with granite.

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. Hydrolysis is the chemical breakdown of a substance when combined with water. Hydrolysis occurs for example when water comes in contact with granite.

The most common example of hydrolysis is feldspar in granite rocks. 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.
