WebIgneous rocks are classified based on texture and composition. Texture describes the physical characteristics of the minerals, such as grain size. This relates to the cooling … WebDec 6, 2024 · Basalt is extrusive. The magma from which it cools breaks through the crust of the earth and erupts on the surface. Because the magma comes out of the earth (and often into water) it cools very quickly, and the minerals have very little opportunity to grow. Is basalt cooled slowly? Why is basalt so hard?

The surface is much closer to the surface of the … Webbasalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium. Some basalts are quite glassy (tachylytes), …
WebExtrusive 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: …
Basalt is usually dark grey to black in colour, due to its high content of augite or other dark-coloured pyroxene minerals, [8] [9] [10] but can exhibit a wide range of shading. Some basalts are quite light-coloured due to a high content of plagioclase, and these are sometimes described as leucobasalts. See more Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. … See more The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene.
