Where is shale formed.

Shale formation usually contains cementing agents such as feldspar and carbonate minerals, which lithifies the deposition and binds the components together (Chilingarian and Wolf, 1988). Sun et al. (2016) explained the degradation of cementation due to long-term contact with CO 2 that led to changes in mechanical properties of rock.shale. « Back to Glossary Index.

Shales are usually deposited in slow-moving water, and their reserves are often found in lakes, lagoonal deposits, river deltas, floodplains, and offshore water resources below the wave base. The fine and small particles that compose shale remain suspended in the water body for a long, and the larger particles settle at the bottom.TAKORDI SHALE Next to the Takoradi Sandstone is the Takoradi Shale. The two formation possess a common characteristic and is obvious they belong to the same depositional phase. The Takoradi Shale is located at Poasi, Tanokrom, Effia Nkwanta and Essipong. The shale is dated to be from the upper Devonian to lower Carboniferous.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. Shale forms from the deposition and compaction of clay-sized minerals in a low-energy environment.

Some uses of this type of rock are provided below. Limestone is used to make cement. Limestone and sandstone are used for building stones. Quartz is a type of sedimentary rock which is used to make glass. Rock gypsum is used to make plaster. Natural gas, oil, coal, uranium, and other energy resources are formed in and come from sedimentary rocks.Most shales are formed in marine environments, with groundwater highly saline. Shale acts as a semipermeable membrane, allowing water to pass through and retaining dissolved stains. Some shales are rich in unoxidized carbon. These are known as black shales, and some of them may also contain heavy metals like uranium, vanadium, zinc, and molybdenum.

The Niobrara Shale is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming.
