The fossils of the Burgess Shale, like the Burgess Shale itself, are fossils that formed around 505 million years ago in the mid-Cambrian period. They were discovered in Canada in 1886, and Charles Doolittle Walcott collected over 65,000 specimens in a series of field trips up to the alpine site from 1909 to 1924. After a period of neglect from ...The Niobrara Shale is a shale rock formation located in Northeast Colorado, Northwest Kansas, Southwest Nebraska, and Southeast Wyoming. Oil as well as natural gas can be found deep below the earth's surface at depths of 3,000 - 14,000 feet. Fracking is used to extract these natural resources. Apr 25, 2017 · Slate is one stage in the metamorphosis of shale, a sedimentary rock, to gneiss, a metamorphic rock. Slate can also form from volcanic rock. In slate, the heated and compacted minerals slowly flow and align themselves perpendicular to the axis of compression, to create "cleavage," which is the tendency of the rock to break along straight lines. Shale is a sedimentary rock formed from clay and silt, while slate is a metamorphic rock formed from shale or clay. Shale has a layered structure and is rich in organic matter, while slate has a fissile texture and is highly compressed and durable. Shale is softer and less durable than slate, which makes it more prone to weathering and erosion ...

According to the US Energy Information Administration (EIA) in 2011, the 1,750-square-mile (4,500 km 2) Monterey Shale Formation contained more than half of the United States's total estimated technically recoverable shale oil (tight oil contained in shale, as distinct from oil shale) resource, about 15.4 billion barrels (2.45 × 10 ^ 9 m 3).This vertical variability is associated with the diversity of the processes and conditions that are involved in shale rock formation. At the rock formation stage, organic matter content is controled on three processes: production, destruction and dispersion. The intensity of particular processes vary depending on the place of deposition.

Mudstone is a sedimentary rock made of very small particles of mud and clay – it is “fine-grained” and often called shale.

He considered that the organisms were buried in a thixotropic sediment that was injected into body cavities. The outlines were replicated as a result of gel stabilization; compression and cementation followed. The reflectivity is enhanced by the compression and orientation of clay minerals against the fossil.Shale gas is natural gas that is formed and trapped in bedrock consisting of shale.

The mudstones and siltstones of the Hermit Shale and Supai Group were laid down by a meandering system of rivers and streams in a semi-arid climate about 280 million years ago.Shale is part of mudstone and claystone but can be distinguished based on structure. Shales are fissile and laminated. The fine lamination is what makes it economically viable as it can store gas between the lattices in free form. Shale is observed in different colors like gray, black, green, brown, or even yellow.The amount of pyrite formed in shale is controlled by the amount and activity of organic matter that can be broken down by bacteria, the concentration of sulfate in the water column, and the amount of active iron (Berner, 1984; Boesen et al., 1988; Middelburg, 1991; Morse and Berner, 1995). Therefore, with the same organic carbon content, the C ...Detritus sedimentary rocks are formed when rock fragments, debris or sediments accumulate over time and can be either organic or inorganic in makeup. These detrital rocks come together under great pressure, usually over many years. The debris, or matter that form the rocks, can be either organic or inorganic. A chunk of coal.
