Granite Hydrolysis Weathering

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

Granite hydrolysis weathering.

Hydrolysis occurs for example when water comes in contact with granite. 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. 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 clay weakens the rock making it more likely to break.

The clay weakens the rock making it more likely to break. Feldspar crystals inside the granite react chemically forming clay minerals. Hydrolysis is the chemical breakdown of a substance when combined with water. 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.

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. Chemical weathering occurs when water dissolves minerals in a rock producing new compounds. This reaction is called hydrolysis. Hydrolysis is the chemical weathering of minerals by a mildly acidic water that forms when rains dissolves trace gases in the atmosphere.

This reaction is called hydrolysis. There are different types of chemical weathering. Feldspar crystals inside the granite react chemically forming clay minerals. Chemical weathering occurs when water dissolves minerals in a rock producing new compounds.
