WebThe difference between the two rock types is their grain size. Basalts are extrusive igneous rocks that cool quickly and have fine-grained crystals. Gabbros are intrusive igneous rocks that cool slowly and have coarse … WebThe grain size of diabase is on the smaller side. Diabase and gabbro have the same general mineral composition as basalt, but they have a larger grain size. Basalt is identical to diabase and gabbro, but is very fine-grained. Basalt is from a melt that cooled very rapidly- in other words, on the surface of the earth or in the ocean.

WebThe grain size of basalt is very fine (usually <1 mm), a result of rapid cooling. Like some terrestrial basalts, some lunar lavas have small, bubble-like holes in them (vesicles), indicating that the magmas contained gas during eruption.
