Green Granite
What is granite?
Granite is an igneous rock. It is formed as a result of the slow crystallisation of molten magma at depth in the earth's crust. Uplift and erosion has over millions of years resulted in this material outcropping at the surface. ...
What is marble?
Geologically this is a limestone that has re-crystallised through the action of heat and pressure (metamorphism) whilst still retaining certain properties of the original material (i.e.: it's chemistry and possibly it's relic sedimentary structures). ...
Natural stone geology
Stone has been used by man for construction purposes for many thousands of years. Geology, which seeks to describe and explain these materials, is a relatively new science, ...
What is limestone?
These materials were originally deposited as soft sediments being laid down as beds under water by a variety of chemical, biological and physical processes. Over millions of years the sediments were buried, ...
What is sandstone?
These sedimentary rocks originated as loose grains of rock materials, predominantly quartz but occasionally felspar or some other mineral. These materials, eroded from older rocks, ...
What is slate?
A slate originates as a sediment usually a fine grained mudstone. Through the action of burial, compression and heat a mudstone will develop progressively from a shale, to a slate; to a phyllite; and then with sufficient heat, to a schist and finally a gneiss. ...
