When clay is deposited it becomes the rock shale; Calcite (CaCO3) is a mineral with rhombohedral cleavage that reacts with dilute hydrochloric acid. ... Clastic rocks (sandstones, shales, etc.) are classified on two criteria - texture (grain size), and composition (that is, QFL). Shale, of course, is both fine...

Diabase and gabbro have the same general mineral composition as basalt, but they have a larger grain size. Basalt: chemically, this is identical to diabase and gabbro, but is very fine-grained. Basalt is from a melt that cooled very rapidly- in other words, ... Shale is not the best kind of rock for mineral prospecting,

Like igneous rocks, they are classified according to their composition and grain size. Sedimentary rocks can be important host rocks for either mineral or petroleum deposits. ... Siltstone: Coarser-grained than shale in grain size, ranging from .00016 to .0025 inches. Also lacks the fissility. Similar to shale in composition,
