magmane
Magmane is a geological term referring to a volcanic rock type. It is a dark-colored igneous rock that is rich in magnesium and iron. The composition of magmane is typically between basalt and andesite, meaning it has a moderate silica content. This classification places it within the intermediate group of volcanic rocks.
The texture of magmane can vary, but it is often fine-grained, indicating that it cooled relatively quickly
Magmane is often associated with volcanic activity in regions with convergent plate boundaries, such as island
