Igneous Rocks

The top 20–25 km of the Earth's crust consists of approximately 95% igneous rocks or their metamorphic equivalents, 4% shale, 0.75% sandstone, and 0.25% limestone. The average chemical composition of common rocks is given in Table 1. It is evident that SiO 2 and Al 2 O 3 account for >70% weight fraction of the lithosphere.

Limestone

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant …

Igneous Rocks | Pictures of Intrusive and Extrusive Rock Types

Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff ...
