It is characterized by alternating beds of arkosic sandstone and mudstone . [1] [3] The Dawson Arkose contains plant remains [4] and other nonmarine fossils , and hosts aquifers that are important sources of water for the area.Above this, mixed arkose, conglomerate, and limestone of the Middle Pennsylvanian Minturn Formation are interpreted to record alternation between shallow marine and fan-delta environments (Figure 2; Hoy & Ridgway, 2002; Lamb et al., 2008; Myrow et al., 2008).Arkose conglomerate and mudstone of the lower Crystal Spring Formation were formed from muddy debris derived from stream erosion of these uplands. A warm shallow sea spread over the area as the Amargosa aulacogen slowly subsided; thick sequences of lime -rich ooze with abundant colonies of algae called stromatolites were then laid down.

The pebb 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.Arkose conglomerates are common in alluvial fan and braided river environments. Transportation in a braided river is very different from a debris flow. In a braided river gravel and sand particles roll and bounce along the bottom in such a way that two characteristic types of bedding called L-Bars (gravel beds) and T-Bars (large planar cross ... 1.
