Because the oil and gas are trapped in tight rock formations, these resources are sometimes referred to as tight oil and tight gas, names that would certainly help alleviate confusion if they were used …

Exercise 7.2 Naming metamorphic rocks; Media Attributions; There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface …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 ...Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). Generally, shale occurs in thin layers or beds and represent low-energy environments such as: offshore deposits of mud in ancient seas, in ...

Each type of rock consists of sediment deposited at different depths in a sea or freshwater resource. Shale forms from muddy deposits that settle out in slow moving water, such as in deltas or along continental shelves. Sandstone forms from sandy deposits and limestone forms from deeper deposits.Shale oil is a high-quality crude oil that lies between layers of shale rock, impermeable mudstone, or siltstone.

Chert is a fine-grained hard sedimentary rock composed of microscopic silica grains, and has a flat fracture. Flint is a variety of chert (mostly of upper Cretaceous age) that has a conchoidal fracture. Marl is a calcareous mudstone.

This group of fossils takes its name from the Burgess Shale rock formation, named by Walcott after nearby Mount Burgess in the Canadian Rockies. The Smithsonian's National Museum of Natural History currently houses over 65,000 specimens. The museum also has a permanent exhibit of the Burgess Shale fauna near the Dinosaur Hall.

Formation and composition of oil shales Geologic origins. Oil shale was formed from sediments laid down in ancient lakes, seas, and small terrestrial water bodies such as bogs and lagoons. Oil shales deposited in large lake basins, particularly those of tectonic origin, are commonly of considerable thickness in parts.

The Marcellus Shale is a thick “blanket” formation that covers 95,000 square miles (61 million acres) across the Appalachian Basin.

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.Shale formations are ubiquitous in sedimentary basins and, as a result, the main organic-rich shale formations have already been identified in most regions of the world. The depths vary from near surface to several 1000 feet underground, whereas the thickness varies from tens of feet to several hundred feet.Formation and composition of oil shales Geologic origins.
