What Type Of Weathering Effects Granite

List the products of chemical weathering of each of the minerals in each of these rocks.

What type of weathering effects granite. Two of these are types of feldspar a group of silica compounds that constitute the most abundant mineral group on earth. Weathering processes on headstones and monuments alison tymon march 2012 weathering is defined as the breakdown of rock in situ that is without being moved. Granite is extremely resistant and sandstone a little less so due to the percentage of quartz that each rock type contains. Observe and measure the effects of chemical weathering and mechanical weathering in a humid climate on headstones of granite and marble each of different ages.

Granite is extremely hard and less affected by the freeze thaw cycle the forces of abrasion and the surface exfoliation processes that are all a part of physical weathering. Living organisms may contribute to mechanical weathering as well as chemical weathering see biological weathering below. Breakdown of rock to depths of many metres induced by the chemical alteration of rock minerals by groundwater. If surface erosion is limited then weathering over thousands and hundreds of thousands of years.

In granites potassium feldspar comes in two slightly different forms orthoclase feldspar and microcline feldspar. Headstones are subjected to weath. Spheroidal weathering spheroidal weathering is most common among coarse grained igneous rocks especially granite and similar rock types. For instance limestone is more prone to chemical erosion compared to granite.

Chemical weathering mostly depends on the rock type and temperature. Biological effects on mechanical weathering. It consists of four main mineral compounds. I know hydroylisis effects the weathering of granite but what temperaures do you need to make it occur.

Other types of rock such as limestone are easily weathered because they dissolve in weak acids. Weathering processes depend upon the pres ence of water the temperature the mineral composition of the rock and its chemical com position. Plagioclase feldspar is a compound of sodium and. Granite is an igneous rock that injects or intrudes as magma into earth s crust and then cools.

Different rock types weather at different rates. K spar color is generally the principal influence on the color of granite. K spar is typically pink to red or white. Chemical weathering is the breakdown of rock induced by reactions between rock minerals and groundwater.

Certain types of rock are very resistant to weathering. Igneous rocks especially intrusive igneous rocks such as granite weather slowly because it is hard for water to penetrate them. Honeycomb is a type of tafoni a class of cavernous rock weathering structures which likely develop in large part by chemical and physical salt weathering processes.
