Ppt Historical Geology Lecture 2 Sedimentary Environments And Historical geology lecture 2. sedimentary environments and paleogeography sedimentary rocks, much more so than igneous or metamorphic, provide a geologic history of a region. ancient environmental conditions lithologic and biologic characteristics of sedimentary rock slideshow 474337 by dex. 5 harry williams, historical geology5 texture (size). particle size in clastic sedimentary rocks reflects the energy of the depositional environment. e.g. (above) nearshore waves crashing on beaches > fairly high energy > coarse textured deposits (pebbles sand); offshore > progressively lower energy environments > progressively finer textured deposits medium sand fine sand silt.

Warm shallow marine environments are also ideal for coral reefs, where the sediment consists mainly of the calcareous skeletons of larger organisms. figure above: more sedimentary environments are depicted. first, there is a gentle, meandering river. second a river delta, third is a lake, and fourth is wetlands. meandering river. 2. introduction the sedimentary environment is the specific depositional setting of a particular sedimentary rock and is unique in terms of physical, chemical, and biological characteristics. the physical features of a sedimentary environment include water depth and the velocity and persistence of water. chemical characteristics of an environment include the salinity (proportion of dissolved. Sedimentary structures form in response to the processes that were taking place during deposition. understanding sedimentary structures allows us to reconstruct those processes and interpret the environment (s) in which they formed. 4.1: stratification. 4.2: structures formed by unidirectional currents.

Figure 7.78 show some of the many different places where sediments are deposited. sedimentologists divide all of them into smaller categories that produce distinctive sediments and sedimentary rocks. most sedimentary environments vary laterally. large basins, for example, are not the same everywhere. so different kinds of sediment can be. 2. landscapes form and constantly change due to weathering and sedimentation. the area where sediment accumulates and is later buried by other sediment is known as its depositional environment. depositional environments are often separated into three general types, or settings: terrestrial (on land), marginal marine (coastal), and marine (open ocean).
