Web22 nov. 2024 · These basalts spread over a spatial distance of ∼260 km across the “Great Gradient Line” (GGL; Niu, 2005 ), a steep gradient in gravity, elevation, topography, … When tectonic forces cause hot mantle rock to creep upwards, the decrease of the pressure on the ascending rock can cause its melting point to drop enough for the rock to partially melt. This produces basaltic magma. Decompression melting can occur in a variety of tectonic settings. Meer weergeven 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. … Meer weergeven The mineralogy of basalt is characterized by a preponderance of calcic plagioclase feldspar and pyroxene.
