Basalt Meaning and Spiritual Properties

Basalt is a stone that underlies more of the Earth's surface than any other rock type. It is a dark, volcanic rock that is caused by the rapid cooling of basaltic lava. Basalt also underlines the Earth's ocean basins. Basalt is lava rock formed when the fires deep in the earth's core meet the surface.

Basalt - Wikipedia

Basalt is an aphanitic 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. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoe

Basalt is the most widely distributed basic extrusive rock, with a SiO 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. Pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needle-like nondirectional arrangement.
