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. It is the most common sedimentary rock.

Shale Rock | History | Origin - Compare Nature
Shale is a fine-grained sedimentary rock which is formed by the compaction of silt and clay-size mineral particles. Shale is available in black, brown, buff, green, grey, red, yellow colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Shale is white. Get to know more about ...
Shale: Sedimentary Rock - Pictures, Definition & …
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.
Shale Rock: Geology, Composition, Uses
Shale forms via compaction, typically from particles in slow or quiet water, such as river deltas, lakes, swamps, or the ocean floor. Heavier particles sink, ultimately forming sandstone and limestone, while clay and fine silt remain suspended in water.Over time, these fine particles settle and build upon each other, forming rock.
Mohs scale of mineral hardness - Wikipedia
The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
Mohs Hardness Scale: Testing the Resistance to …
10-9-2017 · Mohs hardness test: When conducting the test, place the unknown specimen on a table top and firmly hold it in place with one hand. Then place a point of the reference specimen against a flat, unmarked surface of the unknown specimen. Press the reference specimen firmly against the unknown, and deliberately drag it across the flat surface while pressing firmly.

Hardness Definition. A measure of the ease with which a smooth surface of a mineral can be scratched, or of its resistance to abrasion. In 1822 the Austrian mineralogist Friedrich Mohs devised a scale based on one minerals ability to scratch another.

CLASSIFICATION // CHARACTERIZATION OF SOME ROCK FEATURES
purpose of rock mass classification, the use of the well -known point load strength index can be useful as the index can be determined in the field on rock core retrieved from borings and the core does not require any specimen preparation. Knowing the rock type and rock material hardness, it is possible for the experienced engineer or
