Skeletal packstone

Skeletal-peloidal wackestone, wacke-packstone, and packstone facies characterize this environment succession. A low-diversity fauna of benthic foraminifera, including miliolids, thin-shelled bivalves, and rare fragmental rudists and green algae characterize the lagoonal environment ( Schlager, 2005 ) with a low-to-moderate energy regime.

Jul 16, 2015 · Carbonate reservoir geology. Carbonate sediments are commonly formed in shallow, warm oceans either by direct precipitation out of seawater or by biological extraction of calcium carbonate from seawater to form skeletal material. The result is sediment composed of particles with a wide range of sizes and shapes mixed together to form a ... Abstract. In the Lower Cambrian of southwest Sardinia, a carbonate platform developed, showing clearly different stages of evolution: (1) a homoclinal ramp containing algal-archaeocyathan mounds (consisting mainly of Epiphyton and Renalcis boundstone) in the west, clastic tidal flats in the east; (2) an ooid-pellet barrier ramp with ooid-shoals, prograding toward the west.Packstone. A Packstone: grain supported by small grains (width of picture is 7mm) Under the Dunham classification (Dunham, 1962 [1]) system of limestones, a packstone is defined as a grain-supported carbonate rock that contains 1% or more mud-grade fraction. This definition has been clarified by Lokier and Al Junaibi (2016) [2] as a carbonate ... It is composed of regularly occurring scoured skeletal wackestone–packstone sheets (LF10) (Fig. 7b) and intervening mudstones (LF3). Skeletal sheets are characterized by fining-up sequences of molluscs, crinoids, brachiopods gastropods, forams and intraclasts that lay above a scoured sole (Fig. 7c). Large crinoids and lithoclasts often fill ...
