Packstone

Lime-sand packstone, orange, crossbedded, with ab

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. InterpretationThe confusion over the packstone stems partly from the lack of proper petrographic documentations in the literature of the origin of their mud matrix. We documented here that mud matrix is commonly incorporated into grainstones via bioturbation or mechanical deformation of peloids converting them into packstones. The process latter is common in ...

This microfacies has a grainstone to packstone texture primarily composed of foraminifera other than fusulinids along with few fusulinids, brachiopods, bivalves and micritized grains (Fig. 4 B). The diversified assemblage of foraminifera and low matrix content indicate a moderate-energy open-marine environment.

Fasies boundstone dapat dibagi menjadi 2 subfasies yaitu subfasies ...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.Boundstone. 1. Framestone.

The ...Sedimentary rock - Limestones, Dolomites, Calcite: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of …Mudstone. Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3]Induration refers to the thickening and hardening of soft tissues of the body, specifically the skin, and is the result of an inflammatory process caused by various triggering factors. Indurated areas commonly appear on the hands and face but can also be found on the chest, back, abdomen, breasts, or buttocks.Mudstone. Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from shale by its lack of fissility (parallel layering). [1] [2] The term mudstone is also used to describe carbonate rocks ( limestone or dolomite) that are composed predominantly of carbonate mud. [3]The debris occurs commonly in bioclastic wackestone to packstone and mudstone within the interstitial spaces of the sessile reef constituents. The wackestone to packstone and mudstone each constitute approximately one fifth of the reefs (22% and 21%, respectively) (Figs. 5 C, 6 A; Table 2).Packstone. 较细粒的含石灰泥, 且呈颗粒支持方式沉积的生物碎屑石灰岩。 57. 悬粒灰岩.
