(yellow cut = good oil) API and fluorescence relationship. 15 -25 API = dark yellow/ orange brown. 25-35 API = yellow. 35-45 API = Blue white. >45 API = gas condensate white to blue white. Caliper Log.Mf4: Bioclast miliolid wackestone/packstone. This microfacies is characterized by more wackestone and low packstone texture and contains dasycladacean algae, echinoderm fragments, gastropods, as well as other fossil debris (10–15%), micritic bioclast (5–8%), and small benthic miliolids foraminifera (20%).The overlying Bryozoan Limestone, dominated by packstone and planar laminated rudstone with bryozoans, gastropods, echinoderms/echinoid spines, and molluscs, indicates deposition within the lower intertidal environment with moderately high-energy conditions. Abundant meniscus cement and biomolds suggest meteoric vadose diagenetic modification ...Limestones show packstone textures delivering benthic foraminifera (15%), bivalves (10%), gastropods (10%), nummulithoclasts (5%) and radiolarians (5%). The upper limit of this sequence corresponds to an abrupt passage from marls rich in benthic foraminifera, bivalves and ostracods to coquina limestones exhibiting a gullied base.The Packstone-biomicrite facies is shown by samples ZC1, ZC6, and ZC9 (Figure 6a-c; Table 2). Petrographic analysis of the C1, ZC6, and ZC9 samples shows that bioclasts make up more than half of the material, with micrite and spar coming in second and third in order.Enos (1983) defines the low-energy platform-interior environment in the modern as restricted shelf, bay, or lagoon, but notes that in the ancient these terms are used loosely for any low-energy, shallow-water carbonates, if there can be shown a barrier seaward. The sediments are dominated by burrowed skeletal muds and muddy sands with peloids ...Under the Dunham classification (Dunham, 1962) system of limestones, a packstone is defined as a grain-supported carbonate rock that contains 1% or more mud-grade fraction. What is a rudstone? A rudstone is a grain-supported carbonate rock containing grains larger than 2 mm. It is the coarse-grained version of a packstone or grainstone. The term rudstonePACKSTONE . Cement filling the interparticle pore space and/or open interparticle porosity; no carbonate mud matrix. GRAINSTONE; Original components not organically bound during deposition. Reworked and transported skeletal and non skeletal grains of which more than 10% grains > 2 mm (Embry and Klovan, 1971)open-marine conglomerates - clasts composed of peloid packstone, bioclast floatstone-wackestone, and lime mudstone, with all lithological types being sometimes mixed in one conglomerate bed with micritic, peloidal and/or skeletal matrix (Fig. 8 A, B). The skeletal component aligned horizontally, with a convex-up or concave-up orientation.The upper contact of the ooid grainstone/packstone facies is either abrupt or somewhat gradational. Many oolites are overlain by skeletal packstone/wackestone, and rarely by quartzose grainstone and peloid grainstone/packstone (fig. 6). Oolitic grainstone or packstone is most abundant in the upper Stevens Member. InterpretationOverall similar to the chaotic breccia (F6), but clasts have more regular shapes resembling nodules, lenses, and thin beds (Fig. 4 A, G-I), are mostly horizontally aligned, and are composed of light brown spicule packstone-grainstone (Fig. 4 J) that is mainly homogeneous, with sporadic examples exhibiting primary parallel lamination or ...Sample L is: a. rock gypsum b. chert c. mudstone/shale d. quartz sandstone e. skeletal packstone/coquina f. conglomerate.

GlacialIf the carbonate is grain supported but contains a small percentage of mud, then it is known as a packstone. If the sediment is mud supported but contains more than 10 percent grains, then it is known as a wackestone, and if it contains less than 10 percent grains and is mud supported, it is known as a mudstone. We analyzed the Member I of the QJM Formation at the Liujiachang section (See supplementary material for detail), which is composed of variably dolomitized subtidal ooid grainstone, intertidal wackestone to packstone with algal fabric, and supratidal dolomicrite with gypsum pseudomorphs (Fig S3).Packstone and wackestone fabrics are compatible with deposition in a low-medium energy open marine environment on the deeper ramp slope between the normal wave base and storm wave base. Depth to storm wave base by comparison with modern Persian Gulf would be 30-50 m (Purser and Seibold 1973 ).25 ივლ. 2022 ... ... packstone.

Unlike locks and keys, access control can offer you more functionality integrating with other systems like CCTV, fire and intruder alarms for a complete solution.Packstone: Packstone limestone facie occur and is essentially dominated by both skeletal and non-skeletal grains (i.e. the bioclasts; fragment of a larger foraminifera, unidentifiable bioclast as well as peloids). The bioclasts and the peloids occur in equal proportion. The micritic mud is the dominating matrix.Porosity is best established in phylloid algal packstone such asmore » Locally, porosity is also associated with fractures and stylolitization. Petrographic observations suggest that formation of moldic and vuggy porosity in this sample was controlled by multiple episodes of dissolution and infill of blocky calcite.This packstone facies is much more grain rich than the matrix in the megabreccia facies. Fossil fragments are the dominant grain type in lower parts of this facies (Fig. 7a).

Well log-derived pore volume mapping demonstrates that the higher energy facies are related to shore-perpendicular porosity, zones suggestive of tidal channels. ...Packstone layers mostly consist of comminuted bioclasts, while floatstone layers are usually characterized by coarse-grained bioclasts with an imbricated fabric (Fig. 12 N). The skeletal assemblage is dominated by LBF associated with small benthic foraminifera, echinoderms, mollusks, and solitary corals, Ditrupa , ostracods, and …Petrographic and geochemical studies were carried out on the Paleocene–Eocene carbonates of the Kolosh Formation in the High Folded Zone to infer the environment of deposition, diagenetic overprints, and their origin. The petrographic study revealed five main microfacies; packstone, wackestone, mudstone, grainstone, and …Packstone a grain-supported fabric containing 1% or more mud-grade fraction Grainstone a grain-supported carbonate rock with <1% mud. Recognising that these classes did not encompass all carbonate lithologies, Dunham defined two additional classes within his scheme: BoundstoneBioclastic packstone lamination passes laterally to the rudist rudstones lenses (SP2) within marly units. Interpretation. These facies correspond principally to tempestite accumulations. The benthic and planktic fauna, similar to those of facies HP, express an environment on the distal part of a reef slope, in a water depth probably greater ...If it is mud supported with greater than 10% grains it is called a wackstone. If the rock is grain supported, it is called a packstone, if the grains have shapes that allow for small amounts of mud to occur in the interstices, and a grainstone if there is no mud between the grains.The interior of the tidal channel is mainly composed of grainstone and packstone, with coarse grain size and permeability generally greater than 100 mD, which is high-quality reservoir with high production. Due to the poor physical properties intertidal channels, the relevant oil production is almost non-existent (Fig. 7).The bioclastic wacke- to packstone facies is interpreted to have developed in a photic, low- to moderate-energy shallow-water environment such as a lagoon or an open subtidal environment, based on the diverse fossil assemblages embedded within wacke- to packstone matrix as well as oncoids (Semeniuk, 1973; Grimwood et al., 1999; Holland and ...An extensive development of massive lime mudstone to packstone occupying the lighthouse area of the penin¬ sula also contains rare undulose Porites corals and may represent coral patches in a lagoonal setting.
