Conglomerate Composition. Conglomerate is a type of sedimentary rock that is composed primarily of rounded or water-worn pebbles, cobbles, and boulders, which are known as clasts. These clasts are typically cemented together by a matrix of finer-grained sedimentary material, such as sand, silt, or clay.

Arkose is commonly a current-deposited sandstone of continental origin, occurring as a thick, wedge-shaped mass of limited geographic extent (as in a fault trough or a rapidly subsiding basin); it may be strongly cross-bedded and associated with coarse granite-bearing conglomerate, and it may denote an environment of high relief and vigorous ... Aug 20, 2009 · Overheads shown in Lab. SEDIMENTARY ROCK: Made from sediments consolidated at the earth's surface. The sediments are deposited at the earth's surface by water, wind, glacial ice, or bio-chemical processes. Typically the sediments are deposited in layers under COOL conditions [thereby distinguishing it from a layered volcanic rock (TUFF)]. The characteristics and distinguishing features of clastic sedimentary rocks are summarized in Table 6.2. Mudrock is composed of at least 75% silt- and clay-sized fragments. If it is dominated by clay, it is called claystone. If it shows evidence of bedding or fine laminations, it is shale; otherwise it is mudstone.Question: Modern Depositional Environments – Death Valley NP, CA.

Examples include: breccia, conglomerate, sandstone, siltstone, and shale. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Examples include: chert, some dolomites, flint, iron ore, limestones, and rock salt. Organic sedimentary rocks form from the accumulation of plant or animal debris.
