Pelmicrite

Laminated, thin-bedded pelmicrite The bed shown below appears on a fresh-cut surface to be a very fine-grained calcilutite, but displays complex textural properties as well as a coarser-grained lithology. The rollover image highlights the development of what can be called a turbidite.

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 ...The Smoky Hill Member of the Niobrara Chalk is composed primarily of olive-gray, well-laminated to nonlaminated impure chalk, which is mostly foraminiferal pelmicrite with packstone or wackestone texture. The rock is characterized by well-stratified grain fabric.Expert Answer.
