Shales | Clays and Minerals

Definition: The term shale is often used as a very general term for all kinds of clay rich sedimentary rocks.Shales are the most abundant kind of all sedimentary rocks accounting for around 60% of the stratigraphic column. As such, most of the time spent drilling oil wells is spent drilling through shales.

Clay vs Shale - What's the difference? | WikiDiff

As nouns the difference between clay and shale is that clay is a mineral substance made up of small crystals of silica and alumina, that is ductile when moist; the material of pre-fired ceramics while shale is a shell or husk; a cod or pod. As verbs the difference between clay and shale is that clay is to add clay to, to spread clay onto while shale is to take off the shell or coat of.

Shale

Illite tends to dominate in older (Paleozoic) shales because burial leads to the illitization process which converts smectite to illite. Mud is a mixture of water, clay and silt (sand). Therefore mudstones also contain various amounts of silt (grain size 2-63 micrometers) and sand in addition to clay minerals.

Shale Rock: Geology, Composition, Uses

Shale is the most common sedimentary rock, accounting for about 70 percent of the rock found in the Earth's crust.It is a fine-grained clastic sedimentary rock made of compacted mud consisting of clay and tiny particles of quartz, calcite, mica, pyrite, other minerals, and organic compounds.Shale is found all over the world in areas where water exists or once flowed.

Shale - Wikipedia

Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Shale is characterized by breaks along thin laminae or parallel layering or bedding less than one centimeter in thickness, called fissility . [1]

Oil shale - Wikipedia

Oil shale is an organic-rich fine-grained sedimentary rock containing kerogen (a solid mixture of organic chemical compounds) from which liquid hydrocarbons, called shale oil (not to be confused with tight oil—crude oil occurring naturally in shales), can be produced. Shale oil is a substitute for conventional crude oil; however, extracting shale oil from oil shale is more costly than the ...
