Chemical weathering mostly depends on the rock type and temperature.
Weathering of granite rock.
If surface erosion is limited then weathering over thousands and hundreds of thousands of years reduces solid rock to a thick mantle of disintegrated rotten rock.
Various researchers engineers and geologists 4 6 12 16 26 32 have tried to do.
Chemical weathering is the breakdown of rock induced by reactions between rock minerals and groundwater.
Breakdown of rock to depths of many metres induced by the chemical alteration of rock minerals by groundwater.
For instance limestone is more prone to chemical erosion compared to granite.
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.
Hence from the engineering point of view it becomes very important to classify the weathering state of a rock mass.
Description of weathering in rocks due to the effect of weathering there occurs an overall change in the engineering properties of rock mass.
Hydrolysis is the chemical weathering of minerals by a mildly acidic water that forms when rains dissolves trace gases in the atmosphere.
Weathering of granitic rocks in east antarctica is controlled mainly by oxidation.
