Abstract:
Fossil benthonic photosynthetic algae capable of calcification contributed to the formation of Indian Cretaceous-Tertiary carbonate deposits. A comparative assessment of different marine calcareous algal assemblages known from various sedimentary basins and their ecological requirements have been highlighted. A comprehensive synthesis and retrospect of research on calcareous algae demonstrate extensive growth of green and red algae during Cretaceous-Tertiary times in India. The calcareous blue-green algae are feebly represented in the Cretaceous deposits and not recorded from the Tertiary depo

The article presents the study results of carbonaceous rocks and taxonomic diversity of the Upper Ordovician calcareous algae of the Tachalov section left half, located on the left side of the same-name creek in the central district of the Charysh-Inya structure-facies zone of Gorny Altai. Six microfacies are distinguished in rocks: algal-bacterial boundstones, crinoid mudstones, crinoid-algal wackestones, polybioclastic wackestones, crinoid-algal packstone-wackestones and crinoid-algal packstones. Calcareous algae of the following genera were recorded in limestones: Proaulopora Volgdin, 1934

Abstract:
Despite the crucial role of epibenthic primary producers (cyanobacteria, green and red algae), no diversity curves for calcimicrobes and calcareous algae are available to assess the pyramiding paleoecology characterizing the Ordovician biodiversification episode. A total of 24 taxa of calcimicrobes and calcareous algae are identified from a Dapingian to lower Katian succession of carbonate sedimentary rocks exposed at the Leyayilitag ridge, Bachu Uplift, Tarim Basin, northwest China. Calcimicrobes (14 taxa), Dasycladales (seven taxa), Bryopsidales (one taxon), and Cyclocrinales (two taxa) cont

The carbonate rocks of the Shella Formation (Middle Eocene) belonging to the Jaintia Group in the Jaintia Hills of Meghalaya are represented by two sandstone units in alternation with three limestone units, viz. Lakadong Limestone, Umlatdoh Limestone and Prang Limestone respectively in chronological order. Umlatdoh Limestone, the middle limestone unit of Shella Formation is conformably underlain by the Lakadong Sandstone and overlain by Narpuh Sandstone. Samples from the Umlatdoh Limestone were collected from the outcrop on the Jowai-Badarpur Road, about 1 km southwest of Lumshnong. Calcareous

The paper presents the results of the study of the remains of cyanobacteria and calcareous algae of the Lower Permian organogenic buildups from the “Pisanyi Kamen’” section at the Un’ya River (Northern Urals). The microscopic study allowed extending taxonomic composition of Early Permian cyanobacteria and algae in the buildups: 3 genera of cyanobacteria, 12 genera of green algae, 2 genera of red algae and 4 genera of unclear systematic position were identified. It was revealed that representatives of green algae of the families Dasycladaceae and Cyclocrinaecae mainly participated in the format

 As a result of the study of the core material of 540 thin sections from the boreholes of the northern marginal part and the paraxial part of the Dnieper-Donetsk Depression (DDD), a complex of fossil red calcareous algae including 14 species of 7 genera, as well as 2 species belonging to 2 genera identified for the first time for the Visean deposits of the DDD has been discovered. The studied carbonate deposits represent the Hlybokynskyi, Sukhynskyi, Stylskyi, Donetskyi and lower part of Mezhivskyi horizons of the Don-Dnipro Rift (DDR). It has been found that the greatest d

Abstract:
Reef profiles are remarkably consistent in general design because they are essentially biological constructions responding to environmental factors. All have reef flats, a horizontal expanse at low tide level that develops when the reef can no longer build upwards and extends horizontally. This is commonly the largest expanse and is the only part that early naturalists could examine until the advent of scuba diving relatively recently. However, it is always relatively depauperate because of the extremes of heat, salinity, and light that affect it. To seaward is the reef crest, commonly constru

The Llucmajor platform on southern Mallorca Island (Spain) is one of the best-exposed Miocene shallow-water carbonate platforms known in the world. Up to 90 m vertical sea cliffs provide a clean, continuous and detailed 3D view of the facies architecture and continuous cores from fifty-two water wells, affording information to interpret the 3D architecture of this 20 km-wide and only slightly deformed carbonate platform. Forty years of research on the Llucmajor platform provided insights into how the mutual interaction of biological and physical processes control the type of carbonate producti
