“…The Lower Permian organic buildups of the Northern Urals western slope are part of a large Visean-Sakmarian carbonate shelf complex. This complex was formed during active regional tectonic movements against the background of the Gondwana continental glaciations (Antoshkina, 2003;Antoshkina & Ponomarenko, 2014;Wahlman, 2002).…”

“…Further, Webb (1996, p. 949) described the biocementstone framework as "…consisting of delicate, small and/or poorly calcified organisms contained within abundant, localized, biologically induced cement". The discovery of organic matter in the Lower Permian cement crusts of the Urals and the study of these crusts by electron spin resonance spectroscopy allowed them to be identified as a result of the synsedimentary calcification associated with microbial activity (Antoshkina & Ponomarenko, 2014). Thus, biocement frameworks are defined here as structures formed by small or thin skeletal or non-skeletal organisms covered by microbial films/crust which induced precipitation of synsedimentary carbonate cements.…”

“…Thus, biocement frameworks are defined here as structures formed by small or thin skeletal or non-skeletal organisms covered by microbial films/crust which induced precipitation of synsedimentary carbonate cements. According to Antoshkina and Ponomarenko (2014), the framework of these biohermal rocks was formed only due to rapid synsedimentary biologically induced cementation, since these small, fragile, sessile organisms alone could not build the framework.…”

“…The hard sea floor was subsequently inhabited by fenestellid bryozoans. After death, colonies were covered with microbial films inducing rapid cementation (Antoshkina & Ponomarenko, 2014). In terms of ecological succession, this interval characterises the pioneer colonisation stage.…”

“…Верхнемиоценовые постройки обрамляют брахиантиклиналь, представляющую собой криптодиапировую складку с ядром нагнетания из сильно перемятых, раздробленных и перетертых глин майкопской серии [12]. Мшанковые биогермы формировались на склонах диапировой складки как пригидротермальные оазисы в мелководном бассейне с газофлюидным высачиванием из грифонов древнего грязевого вулкана [36]. Голоцен-верхнеплейстоценовые глубоководные органогенно-карбонатные постройки размером, редко превышающим 15-20 см в длину, формировались на Срединном Атлантическом хребте (САХ) на глубинах около 3 км, во внеосевой зоне рифтовой долины с активным вулканизмом.…”

The isotopic composition of carbon and oxygen of 165 samples of carbonate rocks of genetically different organogenic structures: the Upper Ordovician Bol'shaya Kos'yu reef, the Upper Devonian Shar'yu microbial mound, the Kozhym skeletal mound, the Upper Miocene Kazantip bioherm complex and deep-water organogenic-carbonate structures of the north of the Mid-Atlantic Ridge was studied. The reef and microbial mound are characterized by δ 13СPDB values within the limits close to normal-sedimentary marine carbonates (–0.33—3.13 ‰) and (0.8—3.0 ‰), but with significant variations in δ 18ОSMOW — (22.24—30.0 ‰) and (20.4—26.3 ‰), respectively. The most isotopically-heavy carbon composition (5.1—7.3 ‰) in combination with varying δ 18ОSMOWvalues (22.4— 30.0 ‰) is characteristic of limestones and brachiopods of the skeletal mound. Fluctuations of δ 13СPDB and δ 18ОSMOW values in carbonate rocks of the Kazantip bioherm complex are the most expressive (–2.76—7.17 ‰) and (24.20—33.1 ‰), respectively. Deepwater organogenic structures from the bottom of the axial zone with active volcanism, in contrast to others, showed stable δ 13СPDB values (–0.98—0.83 ‰) within the area of normal-sedimentary marine carbonates, whereas for oxygen the values are istopic-heavy (32.27—39.75 ‰). As a result, the specificity of the development of the objects under study, established by lithological-paleoecological and chemical-physical methods, found its substantiation in isotopic values, paleosalinity and paleotemperatures caused by paleogeographic and climatic conditions.

ЛИТОФАЦИАЛЬНЫЕ ОСОБЕННОСТИ ИЗВЕСТНЯКОВ НИЖНЕЙ ПЕРМИ СТЕРЛИТАМАКСКИХ ШИХАНОВ (LITHOFACIAL FEATURES OF THE LOWER PERMIAN LIMESTONES OF THE STERLITAMAK SHIKHANS)

The article deals with the lithofacial features of the Asselian and Sakmarian limestone of the Cisuralian Series of the Permian System, composing the particular mountains Yuraktau, Kushtau and Tratau on the right bank of the Belaya River near the city of Sterlitamak in the Bashkir PreUrals. Biohermic and bioclastic (detrital) lithofacies are distinguished in the limestone composition. Biohermic types are represented by bryozoans and coral framestones and rudstones, tubiphytes packstones, palaeoaplisyna boundstones and rudstones. Granular or bioclastic lithofacies are represented by fusulinid, crinoid-fusulinid grainstones, bryozoans and bryozoans-tubiphytes packstones, crinoid and polybioclastic packstones and wackstones. Polybioclastic packstones and crinoid-fusulinid grainstones predominate in the section of the Lower Permian limestones. In the Asselian part of the section, at the base of the shikhans, there are bryozoans and bryozoans-tubiphytes lithofacies. These limestones make up the shihan Toratau. Coral lithofacies are common in the section of shikhan Yuraktau in the upper part. On the Mount Kushtau, according to drilling data, coral types are confined to the upper part of section, to the Sakmaian stage. The top of Mount Kushtau is composed of palaeoaplisyna limestones composing stratified bioherms with a thickness of up to 40 m. The distribution of limestone lithotypes by section shows the change of the bryozoans-tubiphytes association in Asselian time by coral- palaeoaplisyna bioherms in the Sakmarian time.
