Assessment of the Influence of Astronomical Cyclicity on Sedimentation Processes in the Eastern Paratethys Based on Paleomagnetic Measurements Using Discrete Mathematical Analysis

The introduction of modern methods for the mathematical processing of geological data is one of the promising areas of study and development in the field of geosciences. For example, today mathematical geology makes it possible to reliably identify astronomical cycles by measuring the scalar magnetic parameters of rocks (magnetic susceptibility). The main aim of this study is to develop a mathematical tool for identifying stable oscillation cycles (periods) in the dataset of the magnetic susceptibility of rocks in a geological section. The author’s method (algorithm) is based on the concept of discrete mathematical analysis—an innovative mathematical approach to the analysis of discrete geological and geophysical data. Its reliability is also demonstrated, by comparison with the results obtained by classical methods: Fourier analysis, Lomb periodogram, and REDFIT. The proposed algorithm was applied by the authors to analyze the material of field geological studies of the Zhelezny Rog section (Taman Peninsula). As a result, stable cycles were determined for the Pontian and Lower Maeotian sedimentary strata of the Black Sea Basin (Paratethys).

Genesis and structure of the iron ore deposit of the Cape Iron Horn

Статья посвящена железорудному месторождению, представляющему собой пласт оолитовых (бурожелезняковых) руд железа, который выходит на дневную поверхность на мысе Железный Рог на берегу Таманского полуострова. Мыс имеет протяженность 1,3 км с запада на восток и высоту 55 м над уровнем моря. Склон мыса разбит многочисленными трещинами из-за эрозионного воздействия ветра и морской воды, по которым происходит откалывание оползневых тел. Актуальность работы. Железорудное месторождение на мысе Железный Рог Таманского полуострова известно с конца 19 века, в настоящее время (с 1984 года) ему присвоен статус памятника природы, из-за чего добыча сырья запрещена на всей охраняемой территории, составляющей 19 га. Однако минералогия, палеонтология и особенности геологии данного месторождения изучены недостаточно. Таким образом, представленная статья призвана в какой-то степени восполнить этот пробел. Целью проведенных исследований является выявление особенностей геологического строения, минерагении и генезиса железорудного месторождения на мысе Железный Рог Таманского полуострова. Методы работы. Основу работы составляют образцы, отобранные авторами во время полевых работ на мысе Железный Рог с июня по июль 2021 года. При выполнении работы были описаны 15 образцов, а также идентифицированы палеонтологические находки и определен их примерный возраст. Результаты работ. Установлено, что бурые железняки залегают в толще серых глин железнорогской свиты (N1-2žr) и совпадают с ними по возрасту, что подтверждается палеонтологическими находками. В разрезе были найдены только те минералы, в состав которых входит железо: борнит, вивианит, лимонит, халькопирит. В работе проанализированы структурно-текстурные особенности пласта и вмещающих его пород, а также ассоциации найденных минералов, на основании чего сделаны выводы, что данный пласт железных руд относится к хемогенному осадочному типу месторождений, образованному из коллоидных растворов The article is devoted to an iron ore deposit, which is a layer of oolitic (brown limestone) iron ores, which comes to the surface during the day at Cape Iron Horn on the shore of the Taman Peninsula. The cape has a length of 1.3 km from west to east and a height of 55 m above sea level. The slope of the cape is broken by numerous cracks due to the erosive effects of wind and sea water, along which landslide bodies are chipping away. Relevance.The iron ore deposit at Cape Iron Horn of the Taman Peninsula has been known since the end of the 19th century, currently (since 1984) it has been given the status of a natural monument, which is why the extraction of raw materials is prohibited in the entire protected area of 19 hectares. However, mineralogy, paleontology and features of the geology of this deposit have not been studied enough. Thus, the presented article is intended to fill this gap to some extent. The Aim of the research is to identify the features of the geological structure, mineralogy and genesis of the iron ore deposit at Cape Iron Horn of the Taman Peninsula. Methods. The work is based on samples selected by the authors during field work at Cape Iron Horn from June to July 2021. During the work, 15 samples were described, as well as paleontological finds were identified and their approximate age was determined. Results.It has been established that brown ironstones lie in the thickness of gray clays of the Zheleznogorskaya formation (N1-2žr) and coincide with them in age, which is confirmed by paleontological findings. Only those minerals containing iron were found in the section: bornite, vivianite, limonite, chalcopyrite. The paper analyzes the structural and textural features of the formation and its host rocks, as well as the associations of the minerals found, on the basis of which it is concluded that this iron ore formation belongs to the chemogenic sedimentary type of deposits formed from colloidal solutions

Steppe communities within the coast of the Taman Peninsula

The article presents the results of field research in 2019–2020 of plant communities of the abrasive coast of the Taman Peninsula. The biomorphological structure of populations is dominated by annual species, which indicates a high dynamism associated with exogenous processes. Ecologically, the dominant species are xerophytes and xeromesophytes, as well as species with a wide eco-amplitude. The process of unification of the studied flora is low and amounted to 17 %. The generalized floristic list includes 231 plant species from 48 families. In the study area, 7 species of Red Book plants were found, of which 2 species were included in the Red Book of the Russian Federation.

COINS FROM THE BOSPORAN NECROPOLIS OF VOLNA 1 ON THE TAMAN PENINSULA

В статье публикуются нумизматические материалы из раскопок боспорского некрополя античного времени Волна 1 в 2014-2018 гг. Монеты являются важными хронологическими индикаторами как для датировки погребений, так и для периодизации истории некрополя в целом. За исключением единственного серебряного пантикапейского диобола (ок. 425-400 гг. до н. э.), все найденные монеты медные. Из 119 монет 117 отчеканены в Пантикапее, одна - в Фанагории, еще одна принадлежит чекану Левкона II. Позднейшая монета относится к митридатовскому времени и отчеканена после 95 г. до н. э. Все монеты использованы в качестве оболов Харона или дара, брошенного в могилу при засыпке участниками церемонии (нет ни одной, представляющей монисто), и являются важным свидетельством как погребального обряда, так и денежного обращения эпохи. The article publishes coins from the excavations of the Bosporan necropolis of «Volna 1» in 2014-2018. Coins are important chronological indicators for both the dating of burials and the periodization of the Volna 1 Necropolis' history as a whole. Except from a single silver Panticapaeum diobol of ca. 425-400 BC, all the remain coins are copper. Of the 119 coins, 117 were minted in Panticapaeum, one in Phanagoria, and another is the Leukon II's striking. The later coin belongs to the Mithradatic period and was minted after 95 BC. All coins were used as «obols of Charon» and provide an important evidence of both the funeral rite and the currency of the epoch.

THE POTTERY ANT HOUSEWARE OF THE VOLNA 12 SETTLEMENT FROM EXCAVATIONS 2013-2015

The settlement of Volna 12 was excavated in 2013– 2015, on the Taman Peninsula. The settlement is located on the south-western coast of the Taman Peninsula, 5.8 km north-west of the outskirts of the Volna village and 1.8 km north of Cape Panagia. The period of the settlement's existence falls on the late 17th (possibly the beginning of the 18th) – early 19th centuries. The settlement with an area of ​​31 hectares has been fully explored, so we have the opportunity to work with its materials in full. The previously unpublished ceramic material of the settlement - dishes and ceramic household items – is considered in the article by groups and categories. Particular attention is paid to non-glazed ceramics, which for a long time remained outside the interests of researchers. The article considers such categories of ceramic vessels as Aquarius, jugs, bowls, household vessels, braziers. The settlement did not exist for a very long period of time (about 100– 150 years), therefore, chronological differences in the ceramic material cannot be found. Obviously, it mainly comes from one or several centres of the South-Eastern Crimea, but the question of the centre of production of these vessels remains unresolved.

A Pliocene Mioproteus (Urodela: Proteidae) from the Taman Peninsula (Russia)

A material of Mioproteus wezei is described from the Plevaka locality of Taman Peninsula in Russia. It represents the most abundant material on the species to date that facilitates the discussion on its taxonomic status. The record of M. wezei from the Taman Peninsula apparently suggests a wide geographic range of the species in Europe during the Pliocene.

COMPOSITION AND STRUCTURE OF PLANKTONIC COMMUNITIES IN THE COASTAL ZONE OF THE TAMAN PENINSULA (KERCH STRAIT, SEPTEMBER, 2018)

The qualitative and quantitative composition of planktonic societies in the southern part of the Kerch Strait in the coastal zone of the Taman Peninsula in September 2018 was studied. The phytoplankton consisted of 84 species, the average values of its abundance and biomass were 106 ± 22 million cells/m3 and 227 ± 32 mg/m3 respectively. The leading role in its composition was played by Nitzschia tenuirostris (by number) and Proboscia alata (by biomass). Zooplankton was represented by 24 species and taxa, its quantitative indicators were 32.5 ± 3.3 thousand individuals/m3 and 0.24 ± 0.02 g/m3 respectively. The copepod Oithona davisae dominated in terms of numbers, Oithona davisae, Parasagitta setosa, Decapoda and Cirripedia larvae dominated in biomass. An analysis of the composition and structure of planktonic communities showed their low structural diversity and evenness, as well as a stress state due to natural and anthropogenic factors. A close trophic relationship was revealed between the quantitative indicators of copepods and phytoplankton, excluding the dominant microalgae, the shape and size of which prevent them from being grazed.
