The contact between the latter two beds is very irregular, indicating an erosional and possibly karstified unconformity . This interval represents the uppermost part of the Bocaina Formation (Boggiani, 1998).The matrix is a wackestone-packstone with calpionellids. The CBZ-3/D subunit, about 8 m thick, is similar to the first one (CBZ-3/A) and presents a metric bedding with a quite homogeneous bioclastic packstone/grainstone texture (Fig. 3 H); quartz grains are scarce. As in CBZ-3/A, ferruginous intraclasts are abundant giving to this subunit its ...

A packstone is a rock with a grain-supported texture with the intergranular voids filled with a finer matrix. wackestone A lime wackestone is a matrix supported carbonate rock containing less than 75% mud-grade (<32 μm) calcite.Capillary pressure curves for a mudstone-wackestone and packstone illustrate approximate upper and lower limits for rocks from the Cheyenne Wells field. Permeable packstones exhibit sufficiently low entry pressure (and equivalent oil column height). These pressures are insufficient for low permeability mudstones, which are water saturated (Sw ...The Suwannee Limestone, originally named by Cooke and Mansfield (1936), consists of a white to cream, poorly to well indurated, fossiliferous, vuggy to moldic limestone (grainstone and packstone).

Bioclastic 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 ...

Grainstone, algal packstone, algal wackestone, and foraminifera wackestone are porous rock types, and echinoderm wackestone and mudstone are nonporous rock types. The types of pore structure in the study area can be divided into four types. Type I has midhigh porosity and medium-high permeability due to its large throat, while type II has a ...

The upper part of this formation is characterized by a 69-m-thick carbonate sequence ...Fenestral peloid packstone and intraclast packstone are commonly associated with each other; the former is much more common than the latter. Peloids mostly range between 0.2 and 0.7 mm in size and display an oval shape (Fig. 4 B). Some peloids may contain as much as 10% quartz silts based on visual estimation. Many peloids are composed of ...Formally defined, a stromatolite is an accretionary organosedimentary structure, commonly thinly layered, megascopic, and calcareous, produced by the activities of mat-building communities of mucilage-secreting microorganisms, filamentous and coccoid photoautotrophic prokaryotes such as cyanobacteria.

Depth to storm wave base by comparison with modern Persian Gulf would be 30-50 m (Purser and Seibold 1973 ).

The packstone microfacies suggest mid ramp setting. The fauna in the packstones microfacies indicates open shelf and normal marine (Wilson, 1975 ). The occurrence of micrite matrix in addition to plenty of typical open-marine skeletal fauna (flat and large Nummulites, echinoids, bryozoans) suggest open-marine environment and low-medium energy ...The packstone facies shows less thickness than the south reservoir (<20 m) and is always associated with ooids, which indicates the possibility of reworking grains by storm waves (Favoreto et al 2016).

An allochem is a carbonate particle that has been transported a short distance and deposited as sediment. Common Allochem TypesRock Type IIB is always a packstone and is usually found in the SO or BCGI lithofacies although it occurs in all lithofacies. The major difference between Type IIB and Type IIA is the absence of large (>0.3 mm) moldic pores in the Type IIB. The lack of large molds and the increase in muddy matrix in Type IIB results in a decrease in porosity as ...Best Selling Brand & Top Flower Awards.

Due to the poor physical properties intertidal channels, the relevant oil production is almost non-existent (Fig. 7).

At the thin-section scale, this facies encompasses a wide variety of microfacies types (Fig. 5), which can be categorized as very fine grainstone with a predominance of fragmented bioclasts, peloids or intraclasts, peloid wackestone, bioclast wackestone, washed intraclast packstone, bioclast and oncoid floatstone, and rarely …Embry and Klovan modification of the Dunham's (1962) biologic classification of organically bound rocks."Floatstone" replaces Dunham's "packstone"; the term "rudstone" replaces grain-supported biogenic limestones, and other organically bound rock are termed "bafflestone," "bindstone," or "framestone," depending on the character of the organic structures.Wackestone. Under the Dunham classification (Dunham, 1962 [1]) system of limestones, a wackestone is defined as a mud-supported carbonate rock that contains greater than 10% grains.
