Limestones are divisible into eleven basic types, which are relatively easy to recognize both in the laboratory and in the field. These rocks are made up of three constituents: (1) allochems, evidently transported or otherwise differentiated carbonate bodies; (2) 1–4-micron microcrystalline calcite ooze matrix, and (3) coarser and ...Family I includes respectively intrasparite, oosparite, biosparite, and pelsparite; family II includes intramicrite and oomicrite (both rare), biomicrite, and pelmicrite. Family III includes homogeneous ooze (micrite), and disturbed ooze with irregular openings filled with …There may be 20-50 of these cou- plets sandwiched between a thicker (0.5-2 cm) bed which is strongly graded from micrite to me- dium-sized sand. The stromatolitic facies also contains beds of a calcareous pelmicrite with nu- merous birds-eyes and is generally thought to have originated from the intertidal realm.Micrite is lime mud, carbonate of mud grade.

• Pelmicrite: consists of pellets with microcrystalline matrix (Figure 10). Depositional Energy Setting and Reservoir Quality Indications. Generally, Family I rocks are formed in high-energy settings and show good reservoir quality, especially if they are partially cemented. Oosparite is considered to be the best reservoir quality rock.Access study documents, get answers to your study questions, and connect with real tutors for PHY CH 234567 at Karachi Institute Of Technology And Entrepreneurship.I need help identifying these carbonate thin sections. We have a bunch of pics and have the options of: oomicrite, oosparite, pelmicrite, pelsparite, biosparite, biolithite, and biomicrite. I can't figure out these three.

The carbonate lithologies include micrite, pelmicrite, thrombolite and biomicrite. Chemoherms and crusts are mainly cemented by aragonite.

Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.
