What are veins of extremely coarse-grained igneous rocks called?
Veins of extremely coarse-grained igneous rocks are called pegmatites. These veins form from the crystallization of mineral-rich magma, resulting in very large crystals due to slow cooling and high water content. Pegmatites are commonly found in association with granitic rocks.
What is the size of crystals in an igneous rock called?
The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).
