What metamorphic rock is formed from shale? What type of rock is limestone? What minerals are found in extrusive igneous rocks? What is feldspar made out of? What is the mineralogy of basalt? What type of composition does an igneous rock have?
With respect to the productivity of gas shales, in petroleum science the mechanical behavior of shales is often classified into rock types of high and low 'brittleness', sometimes also referred to as 'fraccability'. The term brittleness is not well defined and different definitions exist, associat...
Shale oil is a high-qualitycrude oilthat lies between layers of shale rock, impermeable mudstone, or siltstone. Oil companies produce shale oil by fracturing the rock formations that contain the layers of oil in a process known as "fracking." ...
Andalusite is an aluminosilicate mineral with a chemical composition of Al2SiO5. It forms at low to medium metamorphic temperatures and pressures where argillaceous rocks (such as shale) are exposed to regional and contact metamorphism. Andalusite is a rock-forming mineral most commonly found in sch...
Variety of Igneous Rocks: There are many different types of igneous rocks based on where they formed and what minerals they contain. They can be extrusive or intrusive, depending on whether they form below the ground or on the surface. They can also be mafic or felsic, depending on their ...

A stone is a small, hard, solid substance typically found on the ground, while a rock is a larger, consolidated mass of minerals.
Financial reports have long lumped shale acreage like cuts of meat,with tier l for the best reservoir rock,and tiers 2 and 3 ranked as lower quality.Tier 1 is rated superior to the lower tiers based on a handful of geological measures related to the oil in the ground and the ability to...
