The Apollo 16 regolith is dominated by anorthositic lithologies (the lightest-colored fragments in the image) and noritic impact-melt breccias (non-glassy gray). Breccia is composed of coarse rock fragments held together by cement or a fine-grained matrix. Like conglomerate, breccia contains at least 30 percent of gravel-sized particles (particles over 2mm in size), but it is distinguished from conglomerate because the rock fragments have sharp edges that have not been worn down. These indicate that the gravel was deposited very close to its sou…Coarse Clastics Conglomerates & Breccias > 2mm Sandstones consist of framework grains plus matrix (finer in size) Quartz Arenite - framework grains are ...

The diameter or width of a clastic sediment grain determines its grain size. Specific ranges of grain size have specific names. Gravel is an overall name for large sediment grain size, which includes boulder, cobble, and pebble. Sand includes sediment grains ranging in size from 2mm to 0.625 mm. Silt is the name of a sediment grain that range ...

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 correlate respectively to very coarse, coarse, medium, fine, and very fine granules.

Diatomite is a sedimentary rock with many uses. It is made up of the siliceous skeletal remains of diatoms, which are tiny single-celled algae. Diatomite is crushed into a powder known as "diatomaceous earth". It is lightweight, porous, relatively inert, and has a small particle size along with a large surface area.Lab Activity 6.3 - Clastic Sedimentary Rocks.

Breccia is a term generally used for an enigmatic rock group that consists of a variety of individual mineral grains or broken fragments of rocks, often very angular and cemented together by a fine grain matrix, and sometimes glassy matrix which may or may not be similar to the composition of rock fragments (Fisher, 1961, Schmid, 1981, Laznicka,...

You might think the only differences between whole wheat and white bread are superficial things, like texture and taste. But it’s also true that whole wheat bread gets touted as the healthier option.Breccia forms where broken, angular fragments of rock or mineral debris accumulate. One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.Instead we propose that fault breccia should be defined, as with sedimentary breccia, primarily by grain size: with at least 30% of its volume comprising clasts at least 2 mm in diameter. To subdivide fault breccias, we advocate the use of textural terms borrowed from the cave-collapse literature - crackle, mosaic and chaotic breccia - with ...It is very possible (and common) for clastic sedimentary rocks to contain more than one grain size. If there is a mix of grain sizes then it is ‘poorly-sorted’, and if all of the grains are uniform in size it is ‘well-sorted’. After grain size, it is important to look at the shape of the grains.
