What is Granite?
Granite is a natural crystalline ingenious rock composed mainly of feldspars and quartz with minor amounts of mica and amphibole minerals. Granite began as a hot, 1400 degrees Fahrenheit, mass of magma or molten rock. The magma rose upward and came to rest and solidified into granite. The granite has been pushed upward and as a result the granite deposits lie just beneath the earth’s surface where it can be easily quarried. Granite is widely distributed throughout the continental crust of the Earth and it is the most common igneous rock found at Earth’s surface.

What is marble?
Marble is simply limestone or dolomite rock that has been compressed and/or heated deep within the earth’s crust. Marble contains clay minerals, micas, quartz, pyrite, iron oxides, graphite, etc.
