We interpret these limestones as storm deposits (tempestites), which accumulated when storm-generated currents transported sediment from a shallower shelf setting into deeper water between fair weather and storm wave base.The Smackover is a regionally extensive Late Jurassic carbonate unit. Three distinct lithofacies are recognized: a thin lower laminated carbonate mudstone and peloidal and oncolitic wackestone and packstone; a thick middle carbonate mudstone interbedded with peloidal and skeletal wackestone and packstone; and a thick upper oolitic, oncolitic, and peloidal grainstone and packstone interbedded ...

They are chiefly composed of carbonate microfacies. The carbonate rocks comprise limestones with an intercalation of dolostones arranged vertically in shallowing upward cycles. These microfacies include sandy lime-mudstones, dolosparites, peloidal oolitic packstones, and coralline bioclastic wackestone to packstone. 5.2.1. Sandy lime …H. Chowdhury R.

They range from skeletal grainstone to wackestone but are predominantly poorly sorted skeletal packstone (Fig. 4a, b). The bulk of the skeletal grains are sand size; larger skeletal fragments and whole individuals make up only a small part of the rock; the matrix ranges from lime- to volcanogenic mud.The upper facies is a white, poorly to well indurated, poorly sorted, very fossiliferous limestone (grainstone, packstone and wackestone). Silicified limestone (chert) is common in the upper facies. Fossils present in the Ocala Limestone include abundant large and smaller foraminifers, echinoids, bryozoans and mollusks. The large foraminifera ...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. It passes up transitionally into more typical lagoonal wakestone-packstone facies. This lies on more massive reef facies

Flint, chert, and jasper are names commonly used by geologists and by the general public for opaque specimens of microcrystalline quartz. The same hand specimen might be called "chert" by one person, "flint" by another, and "jasper" by a third. The name used can be influenced by the educational background of the person, the physical properties ...

skeletal wackestone to packstone. Oolitic shoal sands (up to 8 meters thick) contain minor intraparticle porosity related to preferential dolomitization of ooids and intergranular (interooid) porosities of 10%. Measured permeability ranges between 0.52 to 0.88 md with 20% oil saturation (Lutz and Allison, 1992; Allison et al., 1993).

Rudist rudstone and grainstone are particle-supported lacking lime mud, which contain bioclastic of bivalve, rudist, etc; mud-lean packstone and packstone are particle supported with lime mud matrix, and the content of lime mud in mud-lean packstone is relatively low than packstone, which contains bioclastic of benthic foraminifera, gastropod ...Mud-dominated packstone: fabric that is grain supported with intergrain volume filled with lime mud.

摘要：. Three textural features seem especially useful in classifying those carbonate rocks that retain their depositional texture (1) Presence or absence of carbonate mud, which differentiates muddy carbonate from grainstone; (2) abundance of grains, which allows muddy carbonates to be subdivided into mudstone, wackestone, and packstone ...3.

According to the composition and mineralogy of the grains that support the carbonate rocks, the following types are identified: (a) dolomitic, oolitic, foraminiferal packstone and (b) sandy, dolomitic, intraclastic, foraminiferal packstone (Fig. 2a, b). The following sections are descriptions of both types.Atlas of sedimetary rocks. khaled magdy. The study of rock s using thin sect ions and a petrographic microscope was initiated by llcnry Clifton Sorby in the middle of the nineteenth century and the first rocks he described were silicified limestones from the Jurassic in Yorkshire. This work was published in 1851.

The orthophragminids packstone facies is occurred in the outer ramp setting (Babazadeh and Alavi 2013). Microfacies B: milliolids - Lockhartia wackstone facies This facies is recognized in Laki Formation limestone, and the association fauna of these microfacies is milliolids and Lockhartia species (Fig. 5 ).This packstone, collected stratigraphically near the bottom of the bench in 1972, is well indurated (Fig. 7 C). Although mollusks are uncommon in the articulated crinoid layers, they are common in the packstone layers, are unabraded, and include delicate taxa such as weakly hinged articulated bivalves and thin-shelled gastropods (e.g ...

In the grainstone-packstone middle interval (MGP), the internal lamination does not correspond to the planar lamination of the Tb Bouma division or to the parallel-lamination of the silty Td division; it consists of parallel lamination marked by recurrent changes in the size of the grains and in the proportion of the mud-rich matrix (Fig. 14 C).
