Packstone.

The reservoir intervals are divided into seven zones, based on porosity, permeability and major diagenetic events, representing high and tight porosity. The best reservoir intervals are consistently found in most of the regressive cycles, which composed of skeletal lime packstone, coarse coral fragments with touching vugs.Fossiliferous wackestone, Packstone, Marly limestone, Sandy limestone, Reefal limestone, Brecciated wackestone/packstone and Chalky limestone.

Three depositional cycles included within Yamama Formation, top cycle comprises inner ramp facies (oolitic grainstone), middle-ramp (packstone, wackestone), and the third bases cycle outer ramp (chalky micrite and gray shale) (Sadooni 1993).The sedimentary texture in these intervals varies from packstone to rudstone and floatstone. In the MF, dominant pore types are interparticle, intercrystalline, intraparticle and mouldic. In the LF, in addition to all abovementioned pore types, dissolution moulds and vugs are frequently recorded that resulted in porosity and permeability enhancement …

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 ...

Most parasequences in the lower, ~35-m-thick upper Toarcian part of the section have a basal dark gray oncoid-peloid wackestone-packstone that grades up into fine peloid packstone and grainstone (rare; Fig. 9 O), which is in turn capped by thick dark gray to orange-brown oncoid-peloid packstone, grainstone to rudstone and/or ooid-peloid ...Bioclastic packstone. The main components of this microfacies are represented by fragments of bivalves, green algae, coral, benthic foraminifers, especially fragments of orbitolinids, echinoids, and spicules of sponge (Fig. 5f). Some pores of bioclasts are filled with a micritic matrix. Miliolids-bearing packstonePackstone.—Grain-supported muddy carbon­ ate rocks are termed packstone (PI. VI). Grain-support is generally a property of rocks deposited in agitated water, and muddiness is generally a property of rocks deposited in quiet water. A rock exhibiting both properties is peculiar, and it is well to have it isolated for further study.This facies is characterized by packstone texture of poorly rounded grain-supported type. The appearance of foraminifera with perforate walls such as Neorotalia and Miogypsinoides, as well as an association of red algae fragments with sparry calcite cement, indicates deposition in a low to moderate energy environment of a middle part of a ...

The substrate is composed of grey thick-bedded wackestone and packstone. Peloids, microbial mat debris and bioclasts constitute most of the volume of the lower part (Fig. 3a). Diverse bioclasts, including bryozoans, small brachiopod shells, a few gastropods, ostracods, crinoids, and foraminifera, are recognized although they are not very abundant.

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 ...

Conclusion. Due to the proprietary nature of many geoscience data, the data size is limited to what was provided in the SEG ML contest, which is a relatively small data set compared to what treasure troves the AI pioneers in the tech sector can dispose of.

The boundary between the echinoderm packstone and the green algae packstone mostly developed as stylolites. There are four types of stylolite on the cores. Type A is the wave-like stylolite ...Member 1 is a medium-bedded, dark-grey, partly dolomitic nodular packstone containing abundant dasycladacean algae, debris of Halimeda, and foraminifera. Member 2 is a dark-grey to blackish, thickly bedded limestone sequence comprised of intercalated thick, dark-coloured wackestone and packstone beds. All beds are separated by …Further, the depositional realm of packstone facies was restricted to shelf lagoons when skeletal debris was derived from nearly shoal areas or reefs to the shallow environment (Harris 2009). The presence of broken skeletal component and planner stratifications reflect high-intensity tidal flows and wave activities in the present case.The pre-evaluation work showed that the lithology of the upper Sar-3 was tight micrite/wackstone, and the lower part is the rudist bearing grain/packstone with good oiliness and property. Sar-4, 5 and 6 zones are the foraminifer and plankton pack/wackstone of high heterogeneity, weak oiliness and property ( Fig. 2 ).Packstone. b) Grainstone adalah batuan termasuk kedalam jenis Allothonous yang matriksnya tidak terikat selama pengendapa,karena batuan mengandung butir/fragmen (>10% grain) dan grain supported.

Dunham published his classification system for limestone in 1962. The original Dunham classification system was developed in order to provide convenient depositional-texture based class names that focus attention on the textural properties that are most significant for interpreting the depositional environment of the rocks. The three criteria used to define the original Dunham classes were: The matrix is micritic, but now partially dolomitized. Oolitic packstone can be found in the bank interior on the flanks of ooid shoals in modern Bahamas (Harris 1983) and similar environments in geological record, e.g., Permian Grayburg Formation, Midland Basin of USA (Barnaby and Ward 2007).Packstone, which contains mud; Mud-supported textures are referred to as: Wackestone, which contains more than 10% grains; Mudstone, which contains less than …

These facies are similar to the MF1 and MF2 described in this study. Lime mudstone, peloidal packstone, mud-lean packstone, and burrowed mud-rich peloidal packstone were described in the subsurface equivalent of D4 (Faridah reservoir), as products of lagoon intrashelf basin (Tang et al. 2018).

Packstone contains lime mud in crude laminae or burrow mottles within dominantly grainy sediment or as mud infiltrated into intergranular porosity (Figure 7C). Isopachous-bladed cement and poikilotopic calcite spar on skeletal grains is followed by equant calcite spar infilling interparticle porosity (Figure 7C,E). Skeletal grains are commonly ...Ooids are spherical or subspherical carbonate grains characterized by an internal concentric structure and average dimensions ranging mainly from 0.25 to 1.00 mm. In Recent, unaltered ooids it is possible to distinguish a variable nucleus (mud aggregate, bioclastic grains, quartz grains, etc.) and an external cortex formed by concentric ...1. Introduction. Young (1989, p. ix) proposed the term ironstone "as a petrological term and as an informal lithostratigraphic term" following original definition by Kimberley (1978) that ironstone is a rock of any age having an iron content > 15 wt%. Ironstones and iron-rich limestones regularly occur as components of recurrent time-specific facies in the terminal Paleoproterozoic (Lin et ...4.1.1. Pengertian Batuan Karbonat.
