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.Shale Formation. A shale formation is a sedimentary rock composed of fine-grained detrital mineral (silt-size particles of quartz and calcite) and flakes of clay and it is characterised by the presence of about 1% to over 20% of Total Organic Carbon content (TOC). From: Journal of Natural Gas Science and Engineering, 2012. Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering include the ...shale gas, natural gas obtained from sheetlike formations of shale, frequently at depths exceeding 1,500 metres (5,000 feet).
