He was ...In this first chemical investigation on the Lebanese carbonate sequence, new data has been used to delineate the main geochemical features of the various formations of this sequence. The Lebanese crustal segment is part of a much larger carbonate platform deposited at the northwestern margin of the Arabian plate. It is made up mainly of carbonate rocks of Jurassic-Cretaceous age. Petrographic ... The middle unit (209 m {690 ft} thick) is a light olive-gray to medium light gray, very thick-bedded to massive cherty limestone. It is primarily a silty and sandy pelsparite, pelmicrite, wackestone, and grainstone sequence which was deposited in restricted circulation in shelf, shelf lagoon with open circulation, and tidal flat environments.

Travertine is an anisotropic rock considered as one of the most popular stone materials in the building industry. Due to its bedding and lamination planes, the determination of rock strength ...The evaporite minerals in the Main Limestone rocks seem to be overwhelmingly early diagenetic in origin in the light of the following observations: (1) calcite or dolomite pseudomorphs after gypsum crystals associated with a fine pelmicrite matrix; (2)associa- tion of such pseudomorphs with oolitic pelsparite; and (3) evaporite solution breccia ...Micrite is lime mud, carbonate of mud grade. In the Folk classification micrite is a carbonate rock dominated by fine-grained calcite. Carbonate rocks that contain fine-grained calcite in addition to allochems are named intramicrite, oomicrite, biomicrite or pelmicrite under the Folk classification depending on the dominant allochem.

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'. Limestones which lack allochems, consisting only of ...
