Pictures and Descriptions of Igneous Rock Types

Jun 03, 2019· Andrew Alden/Flickr. Basalt is an extrusive or intrusive rock that makes up most of the world''s oceanic crust. This specimen erupted from Kilauea volcano in 1960. Basalt is fine grained so the individual minerals are not visible, but they include pyroxene, plagioclase feldspar, and olivine.These minerals are visible in the coarse-grained, plutonic version of basalt called gabbro.

Recent Advances in Understanding the Geology of Diamonds ...

The kimberlite eruptions that transport diamonds to the surface also carry samples of lithospheric mantle rocks called xenoliths. From these samples, we know much about the mantle keel beneath the continents, such as the fact that it also contains about 5% of the high-pressure form of basalt known as eclogite. The mantle keel hosts nearly all ...
