Skeletal packstone

In oil and gas industry, classifying carbonate rocks is a major step in core and thin section description. Two classification systems have been widely used in the industry: Folk (1959,1962) Classification. Dunham (1962) Classification. Both classifications provide an indication of depositional energy setting and reservoir quality..

Organelles of a skeletal muscle cell contain the same organelles as other animal cells, with the addition of myofibrils. Muscle fibers within the skeletal cell are known as myofibers. These organelles allow skeletal muscle cells to contract...Nov 1, 2016 · The MFS is at the base of the non-fossiliferous lime mudstone containing abundant wispy kerogenous laminae in more basin-central positions. Locally, this mudstone rests on thin skeletal packstone sheet or thicker skeletal wackestone-floatstone. Updip, the MFS is at the base of laminated dolomite that occurs on top of a thin skeletal packstone. are Skeletal Packstone, Red Algae Packstone, Foram Packstone, and Boundstone with diagenetic environment Mixing Zone, Fresh Water Phreatic, and Meteoric Vadose.
