The rollover image highlights the development of what can be called a turbidite. The complex interbedding of the pebbly pelmicrite, mottled micrite, and the calcareous conglomerate, as well as the presence of rip-up clasts and pebble lenses in the pebbly pelmicrite facies, are ... 6 thg 3, 2013 ... Pelsparites are more common than pelmicrites, although both classes of rocks show well sorted texture, frequently with excellent cross-bedding.

Microfacies analyses of these bodies reveal multiple generations of carbonate cements, pyrite, and clotted pelmicrite. Scanning electron microscope (SEM) analysis performed on clotted micrite shows the presence of pyrite spheroids and micrometer-sized filamentous structures. Oxygen isotopes of micrite revealed slightly depleted values ranging ...

ABSTRACT. 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 ...

For example, a limestone comprising pellets in a mud matrix is called a ‘pelmicrite’, and a limestone comprising shell fragments with a sparry calcite cement is a ‘biosparite’. It is possible to combine the prefixes of several allochems where appropriate, e.g. ‘oobiosparite’.Rocas calcáreas o carbonatadas.

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.The original copyright holder is not, Sanuja Senanayake.
