GENERAL GEOLOGY

Detailed explanation-1: -Origin. Granite is an igneous rock and is formed from magma. Granite magma has many potential origins but it must intrude other rocks. Most granite intrusions are emplaced at depth within the crust, usually greater than 1.5 km and up to 50 km depth within thick continental crust.

Detailed explanation-2: -Granite is also used for ornamental statues and monuments. Granite is mined throughout SC, and SC’s state stone is Winnsboro blue granite. Because granite takes millions of years to form, it is considered a non-renewable natural resource.

Detailed explanation-3: -Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite. A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter. Common rocks include granite, basalt, limestone, and sandstone.

Detailed explanation-4: -Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas. It consists of coarse grains of quartz (10-50%), potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock.
