Diabase (Dolerite) OoCities
As presented in Table 2 of the section on Rock Properties a typical diabase has an unconfined compressive strength that can be considerably higher than that of a typical granite or other coarse-grained igneous rock. This means that a solid diabase sphere is usually more durable than that of a granite block, and when pounded against granite, the granite will mechanically
