Black sand beaches are typically formed by volcanic activity, where volcanic rocks and minerals are broken down into sand-sized particles over time. The black color comes from minerals like basalt and lava that make up the volcanic material. These beaches are often found near active or dormant volcanoes.
The dark color of mafic igneous rocks is attributed to dark minerals like biotite mica, olivine, pyroxene, and iron and magnesium. Felsic igneous rocks are lighter in color.
