The Brachina Formation shows a similar type of detrital mineral assemblage to the Enorama Shale, but with differing abundance and grain size. Detrital phases include quartz, K-feldspar, albite, mica, 2M 1 illite, chlorite, and a small quantity of rutile and apatite. The detrital grain size in this formation varies in each lamina (Fig. 6 a). The ...Sand includes sediment grains ranging in size from 2mm to 0.625 mm. Silt is the name of a sediment grain that range in size from 0.625 mm to 0.0039 mm. Mud is the smallest grain size and is also known as clay. It is important to distinguish the grain size called clay from the mineral called clay. Clay sized grains are too small to see ... Angular sand-sized grains are approximately 70% quartz, 20% lithic fragments, and 10% feldspar. Silt and clay make up ~20% of the rock. Clastic sediments are deposited in a wide range of environments, including from melting glaciers, slope failures, rivers (both fast and slow flowing), lakes, deltas, and ocean environments (both shallow and deep).

SANDSTONES account for about 20% of the Earth¹s sedimentary rocks CLAY and SILT sized grains are dominated by clay minerals All clay minerals have a good cleavage. If the cleavage planes are lined up parallel to each other the rock is said to be FISSILE - A SHALE is a fine grained clastic rock with fissility.

3) Shale: Fine-grained clastic sedimentary rock, silt and clay sized grains. Sediment deposited in lake bottoms, river deltas, floodplains, and on deep ocean floor. Fissile=Splits into thin layers. 4) Siltstone: Slightly coarser-grained than shales, non-fissile. 5) Claystone: Predominantly clay-sized grains, non-fissle

The Ta division of the Bouma sequence with normally graded bedding was formed mostly from clay- sized suspended grains with a small proportion of silt-grade saltating grains.As a glacier flows it picks up everything from clay-sized grains to large boulders. Glacial till is a heterogenous mixture of rocks sourced from anywhere the glacier may have moved. This often includes crystalized igneous and metamorphic rocks like gneisses and granites but can be any terrigenous rock within the glacier's conveyer belt.

Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials. This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.

Shale is a rock composed mainly of clay-size mineral grains. These tiny grains are usually clay minerals such as illite, kaolinite, and smectite. Shale usually contains other clay-size mineral particles such as quartz, chert, and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide ...

Shale is a fine-grained sedimentary rock composed primarily of clay minerals and other clay-sized particles of minerals like quartz and calcite. It is laminated and fissile, easily breaking along bedding planes. Shale forms from the deposition and compaction of clay-sized minerals in a low-energy environment.

Clay is so fine-grained it is rarely possible to see the individual mineral particles with the naked eye. The definition of clays describes rocks with particle sizes of less than 4 μm in diameter. Most sedimentary rocks are described using both mineral content and particle size. Silt is intermediate in size between the larger grains of sand and the smaller clay particles. To be classified as silt, the particles must be smaller than .06 millimeters in diameter, (.002 inches) and larger than clay-size particles, which are smaller than .004 millimeters in diameter (.0002 inches).The analysis of the grain size is a typical laboratory test carried out in the field of soil mechanics. The purpose of the analysis is to deduct the distribution of soil particle size. The analysis is carried out using two techniques.

They are intermediate in size between coarse clay on the small side and fine sand on the large side. In other words, a tiny silt grain requires a greater velocity to be eroded than a grain of sand that is 100 times larger! For clay-sized particles, the discrepancy is even greater.
