a sedimentary rock formed by the deposition of successive layers of clay
Rock that is often impervious to water (will not allow water to move through it) but rather soft, brittle, and easily eroded Shale is the result of compaction of silt or mud Much of the Permian and Pennsylvanian strata in Kansas consists of various shales, often brightly colored
{i} sedimentary rock composed of extremely thin layers of silt and clay
A fine-grained detrital sedimentary rock, formed by the consolidation, especially compression of clay, silt or mud

A fine- grained sedimentary rock of a thin, laminated, and often friable, structure
A fine-grained sedimentary rock formed by the compaction of clay or mud
A type of rock that splits easilyalong the plane in which it has been laid down
A fine-grained sedimentary rock, formed by the consolidation of clay, silt, or mud It is characterized by finely laminated structure and is sufficiently indurated so that it will not fall apart on wetting
What they'll do if New Haven ends up underwater
A sedimentary rock that forms when mud or clay turns to stone
A fine-grained sedimentary rock formed by the consolidation of clay, silt, or mud It is characterized by finely laminated structure which imparts fissures parallel to the bedding along which the rock may easily break It may be red, brown, black or grey in colour
A mineral made up of thin sheets of clay Kimmeridge shale from Purbeck, Dorset was used in making bracelets, buttons, beads, cups and pulley-rings
a very fine-grained, thinly layered sedimentary rock composed of clay and/or mud grains less than 1/256 mm in size Shales break easily along their layering, especially along weathered surfaces They feel smooth to the touch, not gritty
Fissile sedimentary rock formed from mud (silt and clay) Where organic compounds are abundant, the shale is black whereas lower organic content results in lighter colors
The rock forms and then turns into hard clay More info - http: //www ivyhall district96 k12 il us/4th/kkhp/RocksandMinerals/shale1 html
A fine grained sedimentary rock composed of clay particles that splits easily into thin layers
A soft type of rock that often breaks into big flat pieces Shale is formed when mud is pressed into rock over millions of years
To take off the shell or coat of; to shell
A fine-grained detrital sedimentary rock, formed by the compaction of clay, silt, or mud
Shale is smooth soft rock that breaks easily into thin layers. a smooth soft rock which breaks easily into thin flat pieces. Any of a group of fine-grained, laminated sedimentary rocks consisting of silt-and clay-sized particles. Shale constitutes roughly 60% of the sedimentary rock in the Earth's crust. Shales are commercially important, particularly in the ceramics industry. They are a valuable raw material for tile, brick, and pottery and constitute a major source of alumina for portland cement. In addition, advances in recovery methods may one day make oil shale a practical source for liquid petroleum. Burgess Shale oil shale shale oil kerogen shales
A fissile rock that is formed by the consolidation of clay, mud, or silt, has a finely stratified or laminated structure, and is composed of minerals essentially unaltered since deposition
shale gas
Natural gas extracted from shale
shale oil
a crude oil, containing hydrocarbons, obtained by the distillation of oil shale
shale gas
Shale gas is natural gas formed from being trapped within shale formations
shale shaker
A vibrating screen used in oil and gas drilling to remove drill cuttings from the circulating drilling mud that is passed through it
shale oil
crude oil from oil shale derived by heating
shale oil
oil extracted from oil shale by heating
shale oil
A crude oil that is obtained from oil shale by heating and distillation. Synthetic crude oil that is extracted from oil shale by pyrolysis, or destructive distillation. The oil obtained from oil shale cannot be refined by the methods that have been developed for crude oil, however, because shale oil is low in hydrogen and contains large amounts of nitrogen and sulfur compounds. To be made usable, shale oil must be hydrogenated and then chemically treated to remove the nitrogen and sulfur, a process too expensive to make shale oil commercially competitive with crude oil. See also kerogen, petroleum
Burgess Shale
A rock formation in the Canadian Rockies that contains very many fossils from the Cambrian period
black shale
A dark, muddy rock, rich in sulfides and organic material
oil shale
a dark-brown or black shale, from which petroleum-like hydrocarbons can be produced by distillation
Burgess Shale
A rock formation in the western Canadian Rockies containing a wealth of fossilized invertebrates of the early Cambrian Period that were buried by an underwater avalanche of fine silt, preserving many details of their soft parts and providing valuable information about the evolution of early life. Fossil formation containing remarkably detailed traces of soft-bodied marine organisms of the middle of the Cambrian Epoch (520-512 million years ago). Collected from a fossil bed in the Burgess Pass of the Canadian Rockies, the Burgess Shale is one of the best preserved and most important fossil formations in the world. Since it was discovered in 1909, over 60,000 specimens have been retrieved from the bed
alum shale
A variety of shale or clay slate, containing iron pyrites, the decomposition of which leads to the formation of alum, which often effloresces on the rock
humic shale
shale that is rich in humic acids
oil shale
shale from which oil can be obtained by heating
oil shale
Shale that is rich in hydrocarbon derivatives, In the United States, a significant oil shale is the Green River Formation, in the Rocky Mountain region
oil shale
A fine-grained, sedimentary rock that contains kerogen, a partially formed oil Kerogen can be extracted by heating the shale, but at a very high cost
oil shale
A black or dark brown shale containing hydrocarbons that yield petroleum by distillation. Any fine-grained sedimentary rock that contains solid organic matter (kerogen) and yields significant quantities of oil when heated. This shale oil is a potentially valuable fossil fuel, but the present methods of mining and refining it are expensive, damage the land, pollute the water, and produce carcinogenic wastes. Thus, oil shale will probably not be exploited on a wide scale until other petroleum resources have been nearly depleted. Estonia, China, and Brazil have facilities for producing relatively limited quantities, and the U.S. government operates an experimental plant in Colorado
oil shale
sedimentary rock containing solid organic material that can be converted to crude oil which is called shale oil
oil shale
A sedimentary rock containing kerogen, a solid organic material
oil shale
A dark-grey or black shale that contains organic substances that yield hydrocarbons, but does not contain free petroleum
oil shale
A brown or black clastic source rock containing kerogen
shaly
Resembling shale in structure

    Pronunciation

    /ˈsʜāl/ /ˈʃeɪl/

    Etymology

    [ 'shA(&)l ] (noun.) 1747. Middle English schale 'shell, husk; scale', from Old English scealu 'shell, husk, pod', from Proto-Germanic *skalō (cf. West Frisian skaal 'dish', Dutch schaal 'shell', German Schale 'husk, pod'), from Proto-Indo-European *(s)kelo- 'split, cleaved' (cf. Lithuanian skalà 'splinter' Old Church Slavonic skala 'rock, stone', Albanian halë 'fish bone, splinter', Sanskrit kalá 'small part'), from *(s)kel- 'to split, cleave' (cf. Hittite iškalla 'to tear apart, slit open', Lithuanian skélti 'to split', Ancient Greek skállein 'to hoe, harrow').
