Piroxienitiä
Piroxienitiä is a rare intrusive igneous rock that is primarily composed of pyroxene minerals. Typically, it is a dark-colored rock, often appearing black or very dark green, due to the abundance of pyroxene. The texture of piroxienitiä is usually coarse-grained, meaning the individual mineral crystals are large enough to be seen with the naked eye. These crystals are commonly euhedral or subhedral, indicating they had space to grow as they formed.
The formation of piroxienitiä occurs deep within the Earth's crust or upper mantle under conditions of high
Piroxienitiä is often found in association with other ultramafic rocks, like peridotites, and can occur as
