WebMay 6, 2010 · As a result, basaltic lava flows can form crusts that are thick enough to walk on in 10-15 minutes but the flow itself can take several months to cool! Because of the insulating properties of lava, it cools slower and slower over time. Thick stacks of lava flows (30 m or 100 ft thick) can take years to cool completely. WebThe time required for the liquid rock to cool will determine the texture. On the other hand, the basalt is an extrusive magmatic rock. The surface is much closer to the surface of the … flag regulation 600-8-2Basalt 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.
