Wednesday, March 06, 2013. Pellets are the excreta of various marine organisms.These grains collect in protected lagoons and shallow intertidal ponds, environments of somewhat lower energy than those where grapestone and botryoidal grains form. pellets commonly are not preserved but disaggregate into micrite during the dewatering and compaction ... The Upper Cretaceous exposures in east central Sinai are represented by carbonate-dominated successions interbedding few sandstone, chert, shale and marl horizons.

Depositional Energy Setting and Reservoir Quality Indications. Generally, Family I rocks are formed in high-energy settings and show good reservoir quality, especially if they are partially cemented. Oosparite is considered to be the best reservoir quality rock.Micrite is lime mud, carbonate of mud grade. Micrite as a component of carbonate rocks can occur as a matrix, as micrite envelopes around allochems or as peloids. The origin of micrites is still a problem in carbonate sedimentology due to the non-uniqueness of the processes generating it. [3] Micrite can be generated through multiple processes ...The dominating biogenic compounds are: (i) calcite as < 5 m[micro] micrite forming the groundmass mudstone, and both micrite of the matrix and > 5 m[micro] to 1 mm grains--skeletal particles (shells and their broken fragments) in wackestone, (ii) silica as < 5 m[micro] particles belonging to the groundmass of mudstone and wackestone matrix, (iii) …It relates more closely to facies 10 and 11 than in the underlying units, where algal-microbial mat levels are well developed.

Allochems: term introduced by Folk (1965) for carbonate particles that have formed by chemical or biochemical precipitation. The main groupsare fossil fragments, ooids, pellets, intraclasts. Allochthonous: refers to carbonate particles that formed outside the basin of deposition (implies substantial transport).

Lacustrine facies record cooler temperatures than the palustrine pebbly pelmicrite and mottled micrite, indicating that water depth played an important role in formation temperatures. δ 18 O water values calculated from Δ 47 values show 18 O-enrichment in the mottled micrite relative to the pelmicrite facies, implying that evaporative periods ...Find 358 researchers and browse 13 departments, publications, full-texts, contact details and general information related to Nevada State College | Henderson, United States |1.Facies 1-Hummocky sequence, find sand with bundles of intersecting low angle cross Lamination, capped by linguid ripples followed by silt.
