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. Shales are often found with layers of sandstone or limestone.
Limestone Sedimentary Rock Mini Me Geology
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. Shale is characterized by breaks along parallel layering or bedding less than one centimeter in thickness, called fissility. It is the most common sedimentary rock.

Shale is a fine-grained, sedimentary rock composed primarily of clay and silt-sized particles. It is characterized by its thin layers or bedding planes, often making it easily fissile and enabling.

In this paper, therefore, we present major and trace element geochemical data of the fine-grained sedimentary rocks (i.e., siltstones and shales) from the Ikorongo basin. The purpose of the study is to constrain source(s) of the Ikorongo clastic sedimentary rocks and to understand the weathering conditions in the source region(s). 2.

are very-fine-grained sedimentary rocks. Slate is the low-grade metamorphic equivalent of these rocks. The main constituents are clay minerals and quartz, and they have grain sizes of less than 0.032 mm (<32 µm) (Appendix 4). In this report the BGS size division 32 µm between very-fine sand and silt has been used (Hallsworth & Knox, 1999).
Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, which.

Fine-grained sediments and sedimentary rocks ("Mudrocks") Mud is a general term lumping together sediments consisting of a mix of clay, silt, and may contain sand. Mud is usually an unsorted mix of fine grain materials. Mud accumulates in quiet water settings separated from where coarser materials have settled out elsewhere (Figure 6.46).

Classifications of fine-grained sediments and sedimentary rocks are based on combinations of several criteria. These include: (1) texture, (2) fissility, (3) tectonic association or environment of deposition, (4) mineral composition, (5) color, (6) chemical composition and (7) degree of metamorphism.

What is Shale? Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.

The lithofacies classification of fine-grained sedimentary rocks is an important basis for the study of hydrocarbon source rocks, shale oil and gas and tight oil reservoirs.

This is especially important.

Chert is a fine-grained sedimentary rock composed of quartz (SiO2) that is microcrystalline or cryptocrystalline quartz. It is usually organic rock but also occur inorganically as a chemical precipitate or a diagenetic replacement. It occurs as nodules, concretionary masses, and as layered deposits.

Despite their abundance, fine-grained sedimentary rocks, to date, have not been satisfactorily classified. Perhaps this is because they are not well exposed in the field compared to their coarser.

Chert ( / ˈtʃɜːrt /) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, [1] the mineral form of silicon dioxide (SiO 2 ). [2] Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood. [3]
