Limestones are the commonest rocks that contain non-silicate minerals as primary components and, even if they represent only a fraction of all sedimentary rocks (about 20 – 25%), their study is fundamental to understand past environments, climate, and ...Description Biomicrite and reefal limestone .

The thin-section petrographic analysis of middel and lower Miocene reefal carbonate indicates that the predominant lithology is biomicrite of mixed packstone and wackestone with almost uniform distribution of the allochems and intergranular material and organic matter content the allochems are dominated by medium to fine calcarenite-sized ...packed biomicrite. views 3,507,324 updated. packed biomicrite See FOLK LIMESTONE CLASSIFICATION.

Source for information on packed biomicrite: A Dictionary of Earth Sciences dictionary.Micrite is lime mud, carbonate of mud grade. Micrite as a component of carbonate rocks can occur as a matrix, as micrite envelopes around allochems or as peloids. The origin of micrites is still a problem in carbonate sedimentology due to the non-uniqueness of the processes generating it. [3] Micrite can be generated through multiple processes ...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.

Its white to yellowish color, together with small (2 mm), densely packed and equally distributed bioclasts, are the main macroscopic characteristics of this stone. Microscopic analysis showed predominance of rudist fragments among bioclasts, and echinoid fragments ...
