Fracking is a type of drilling technique that involves fracturing rock deep underground in order to extract shale gas – a natural fuel that is trapped within shale formations. Energy firms will drill vertically down into the ground at between 6,000ft and 10,000ft, and then horizontally by more than a mile. Nettetsediment to form shale. Evidence that this shale was once schist might be found by analyzing the chemical composition of the shale and the composition of of the schist to see if there is a correlation. There may also be uncommon / rare minerals only present in the schist that are found as clasts in the shale. NettetShale forms when very fine-grained clay particles are deposited in water which settle at the bottom of water bodies.

Shale is characterized by its tendency to split into thin layers … Se mer Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable bedding planes. … Se mer Shales are typically gray in color and are composed of clay minerals and quartz grains. The addition of variable amounts of minor constituents alters the color of the rock. Red, brown and … Se mer Shale is the most common source rock for hydrocarbons (natural gas and petroleum). The lack of coarse sediments in most shale beds reflects the absence of strong currents in the waters of the depositional basin.
