They host polymetallic deposits which have been mined for Cu, Ni, Zn, Mn, P, Mo, V, U, Au and PGE (platinum group elements). Even sub-economic occurrences provide potential risk of acid rock drainage when exposed to oxic surface environment.One of the key principles of sedimentary geology is that the ability of a moving medium (air or water) to move sedimentary particles—and keep them moving—is dependent on the velocity of flow. The faster the …4.2.3.1 Sedimentary Environment. The sedimentary environment plays a key role in controlling the distribution of oil shale. The Tongchuan oil shale was formed in a deep–semi-deep lacustrine facies sedimentary environment in the Triassic period. This oil shale is lacustrine black oil shale and represents the peak period of lake basin development.

Shale is a rock that has been formed from the compression of mud over time. Some black shale contains organic compounds that can be converted to oil or natural gas. Other colors of shale are crushed and mixed with water to create clay.Oil shale - Pollution, Mining, Energy: The production of oil from shales has a potentially serious impact on the environment.

By integrating cores, thin sections, X-ray diffraction analysis, trace elements, organic geochemical indexes, and paleontological data, this work studies sedimentary environment elements and sedimentary model of shale in ...Shale is a lithified mud — a sedimentary rock composed mostly of clay- and silt-sized grains. There are several ways to define shale. Some definitions are rather narrow. Glossary of Geology published by the American Geological Institute defines shale as a laminated, indurated rock with >67% clay-sized minerals 1. Responsible development of America's shale gas resources offers important economic, energy security, and environmental benefits. We work with states and other key stakeholders to help ensure that the economic prosperity from unconventional oil and natural gas extraction does not come at the expense of public health and the environment.Shale is a fine-grained sedimentary rock composed primarily of clay minerals and other clay-sized particles of minerals like quartz and calcite. It is laminated and fissile, easily breaking along bedding planes.
