Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g., kaolin, Al 2 Si 2 O 5 4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. [1]

Shale: Shale breaks into thin pieces with sharp edges. It occurs in a wide range of colors that include red, brown, green, gray, and black. It is the most common sedimentary rock and is found in sedimentary basins worldwide. What is Shale?

Shale, any of a group of fine-grained, laminated sedimentary rocks consisting of silt- and clay-sized particles. Shale is the most abundant of the sedimentary rocks, accounting for roughly 70 percent of this rock type in the crust of the Earth.

Aug 21, 2023 · Shale is a laminated or fissile clastic sedimentary rock that composed of predominance of silt and clay other minerals, especially quartz and calcite. Characteristic properties of shale is breaks along thin laminae or parallel layering or bedding called fissility. It is most abundant sedimentary rock.

Aug 2, 2020 · 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.

Jan 8, 2024 · Shale is a fine-grained sedimentary rock, composed mostly of clay particles and other minerals such as quartz and calcite. It is formed of many thim mineral layers and is typically...

Shale is a fine-grained clastic sedimentary rock characterized by its fissility, shale readily cleaves into thin, typically less than 1 centimeter thick, laminae. Shale primarily composed of clay minerals, along with minor constituents like quartz and calcite.

What is the Eagle Ford Shale? The Eagle Ford Shale is a hydrocarbon-producing geological formation of significant importance due to its capability of producing both natural gas and also more oil than other traditional shale plays.

The Eagle Ford Group (also called the Eagle Ford Shale) is a sedimentary rock formation deposited during the Cenomanian and Turonian ages of the Late Cretaceous over much of the modern-day state of Texas.

Apr 24, 2017 · When shale is buried deeper, for a longer time, and heated by the Earth's crust, it forms slate. The qualities of shale and slate vary with the makeup of the original sediments, the degree of compaction, the amount of heat and the length of time involved.
