Basalt - Wikipedia
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. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbr… See more
- Red basalt is a type of volcanic rock that has a dark color and a high content of iron oxides123. It can form by eruption from a volcano as a molten blob and cooling in the air1, or by eruption underwater and reacting with seawater3. The iron oxides are responsible for the reddish purple color of the basalt23.Learn more:✕This summary was generated using AI based on multiple online sources.

It is typically dark in color (brown, black or purplish-red), and basaltic or andesitic in composition.en.wikipedia.org/wiki/ScoriaThe most common type of rock that contributes to red soil is called basalt. The process of weathering breaks down the basalt into smaller pieces, and then the smaller pieces are broken down further into silt and clay. The iron oxides in the rocks are what give the soil its reddish colour.www.vedantu.com/geography/red-soilBasalt erupting underwater can react with seawater to modify or replace minerals in the basalt. When iron is released from alteration of minerals it may become oxidised to form hematite giving the basalt its reddish purple colour.en.wikipedia.org/wiki/Pariwhero_/_Red_Rocks
