Fine-grained and lower porosity igneous rocks, such as basalt and diabase (dolerite) are generally higher in rock hardness than that of coarser grained igneous rocks, such as granite, diorite, and gabbro. As a result, the mineral grains of fine-grained igneous rocks are more tightly held together than that of coarse-grained igneous rocks.
