Breccia Fig. 6.8Limestone can contain various types of fossils, ranging from microfossils to macrofossils, depending on the depositional environment and age of the rock. Microfossils found in limestone can include foraminifera, coccoliths, and diatoms, while macrofossils can include shells of marine invertebrates such as mollusks, bryozoans, and corals.Packstones indicate a range of depositional properties. Mud suggests lower-energy processes, whereas the abundance of grains suggests higher-energy processes. Dunham (1962) provided several scenarios for the origin of packstones: (1) they may be a product of compacted wackestones, (2) they may result from early or late mud infiltration of ...

There are three primary facies associated with deep marine sedimentary deposition: mud limestone, which is primarily composed of calcareous ooze from calcareous planktic organisms; chert ...Introduction. A depositional environment is a specific environment in which sediments are deposited. They are sometimes called sedimentary environments. The layers of sediment that accumulate in each type of depositional environment have distinctive characteristics that provide important information regarding the geologic history of an area.For example, in the Grand Canyon, rock strata of the same geologic age include many different depositional environments: beach sand, tidal flat silt, offshore mud, and farther offshore limestone. In other words, each sedimentary or stratigraphic facies presents recognizable characteristics that reflect specific, and different, depositional ... …

Transitional sandstone environments include deltas beaches, lagoons, tidal flats, salt marshes, and barrier islands. Delta is a sandstone marine depositional environment located at the mouth of a river. Possible cross-beds and ripple marks characterize it. 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. event recording The sediment preservation potential is very high in these environments because deposition often occurs on the continental shelf and underwater.
