Basalt is a finely granulated igneous rock, which is usually black or gray in color. Most basalt rocks are primarily composed of the minerals pyroxene and feldspar. These rocks are formed due to lava flow. It is a type of rock that is abundantly found in the crust of the Earth, and although now found very commonly on land, most ocean floor

Nov 17, 2012Left, from top: scoria, basalt, gabbro. Right, from top: obsidian, rhyolite, granite. Extrusive igneous rocks form when molten rock (magma) is cooled outside the ground, either in the air or underwater. Each rock''s properties depend on how fast it cools and how much silica is present. The faster it cools, the finer the grains within the rock.

Igneous rocks are formed from molten rock called magma. They are mostly crystalline (made up of interlocking crystals) and usually very hard to break. Basalt. Basalt is made of finegrained interlocking crystals (about 1mm in size). It is black or dark grey in colour, and often contains vesicles – bubbles of gas trapped as the lava cooled.
