Sediments of the Lower Devonian continental red-terrigenous formation of the Dniester series of the Lviv Paleozoic troughwere formed in the alluvial facies environment mainly in the oxidizing medium (they have a red color), and some of them are inthe restorative (gray color of the sediments). In the process of formation and existence, sedimentary formations of the LowerDevonian continental red-terrigenous formation underwent a number of successive stages of lithogenesis: sedimentary, diaand catagenesis and were significantly influenced by glazing processes at the stage of diagenesis. The authors investigatedthe catagenetic transformations of sandstones, siltstones, argillites, rocks of mixed composition of different facies (channel,riparian and floodplain facies conditions) taking into account geochemical (both oxidative and reductive) conditions of formation.A high degree of catagenetic transformations (up to the stage of late catagenesis) of rocks has been established. It was foundthat the nature and intensity of catagenetic transformations not only of different petrotypes, but also of the same type of rocksof different facial affiliation differ significantly, even if they are at the same stratigraphic level. It is established that the degreeof catagenetic transformations of sediments depends on their structural and textural features, material composition and facialaffiliation

Four stages of development of the late Carboniferous vegetation cover have been established that correspond to the time intervals of four regional subdivisions of the Donets Basin − the Toretsian and Kalynovian Regional Stages, the Luganskian and Vyskrivskian Horizons of the Myronivskian Regional Stage. The analysis of phytostratigraphic and paleophytocenological data showed that the stages of vegetation development are characterized by the dominant plant communities in rank of orders of widespread landscapes. Сhanges from one stage to another are considered as the paleophytocenotic events, which are expressed by the changes of dominant communities of certain landscape types. The levels of paleophytocenotic events coincid with the bases of regional subdivisions The bases of the Toretsian and Kalynovian correspond to the levels of paleophytocenotic events, which were manifested by the formation of new communities types as a result of the evolutionary renewal of composition of wetland calamitean-fern and fern-pteridosperm forests of coastal lowlands as well as lycopsid and calamitean-fern forests of deltaic plains. The base of the Myronivskian (Luganskian Horizon) corresponds to the level of the paleophytocenotic event that was expressed by, firstly, the appearance of new communities types of seasonally dry pteridosperm woodlands of river valleys as a result of the evolutionary renewal of their composition, secondly, the appearance of new communities types of wetland calamitean-fern woodlands of coastal lowlands and calamitean-fern and pteridosperm woodlands of deltaic plains, the formation of which were due to the reduction of species compositions and the changes of dominants. The lower boundary of the Vyskrivskian Horizon corresponds to the level of the paleophytocenotic event that was expressed by the appearance of new communities types of wetland calamitean-fern and fern-pteridosperm woodlands of coastal lowlands and seasonally dry fern-pteridosperm woodlands of lacustrine-lagoon plains, the formation of which were associated with plant migrations and the appearance of new dominants. The considered paleophytocenotic events are manifestations of phytocoenogenetic processes, which led to paleophytocenotic changes, and mark main palaeoecosystem transformations in view of vegetation development stages.

Detailed new data on paleontology and stratigraphy were obtained in the process of fulfilling the tasks of the International Carboniferous Subcommission on definition of the scopes of the Moscovian and Kasimovian global stages and the precise position of the boundary between them. The analysis of these data has shown that the position of this boundary in the type area and in the other regions needs the revision. Recently the investigation of the conodonts from the Moscovian–Kasimovian boundary deposits in the Donets Basin revealed that the boundary between the Moscovian and Kasimovian stages in the official Ukrainian Carboniferous Stratigraphic Scheme does not correspond to this boundary in the type area of these stages in the Moscow Basin. To correct this situation the lower boundary of the Kasimovian in the Ukrainian Scheme must be downgraded by two conodont zones — Swadelina subexcelsa and Sw. makhlinae. To update this boundary in the type area to fulfill the task of the Carboniferous Subcommission four conodont species were proposed as potential index-species for the definition of the boundary between the Moscovian and Kasimovian global stages. These conodont species are as follows Sw. subexcelsa, Idiognathodus sagittalis, I. turbatus and I. heckeli. One of these species, which is selected, will be used as a marker of the studied boundary. None of these species is officially selected as a marker. If Sw. subexcelsa will be selected, the position of the Moscovian–Kasimovian boundary will remain at the present position. In this case this boundary in the Donets Basin has to be downgraded by two conodont zones. If one of three Idiognathodus will be selected, this boundary in the type area will be upgraded by one and a half regional substage. In the Donets Basin it will be upgraded by less than a cycle. Keywords: Carboniferous, stratigraphy, conodonts, extinction event, index-species.

Шарувата будова осадових товщ є найбільш помітною і поширеною літологічною властивістю. В узагальнюючій геологічній літературі часто трапляється лише констатація її наявності і глобальності розповсюдження, але відсутнє будь‐яке пояснення її виникнення або ж воно істотно відрізняється. При аналізі попередніх досліджень з’ясовано, що в її утворенні задіяна велика кількість чинників. Показано, що такі фізичні чинники, як сила тяжіння і динаміка середовища перенесення осаду, мають більш глобальний характер і проявляються в усіх обстановках седиментації, на відміну від решти геологічних чинників. Вони також відіграють значну роль в утворенні шаруватості, як і взагалі седиментогенезу, але мають підпорядковане значення і проявляються не завжди. При вивченні літогенезу спостерігається певна неузгодженість, коли при описі седиментогенезу використовуються переважно загальногеологічні чинники, а діагенезу і катагенезу — тільки фізичні та хімічні. Ще однією неузгодженістю є те, що при теоретичних і практичних геологічних дослідженнях значно більше уваги приділяється кількісному вивченню потужностей осадів, а не площ їх поширення. Поза увагою залишається вивчення залежностей між цими геометричними величинами, що кількісно характеризують осадовий шар. Показано, що такі залежності присутні, щонайменше, в осадовій товщі, яка покриває північну частину Українського щита. Вивчення таких залежностей на всіляких територіях може сприяти кількісній оцінці чинників впливу на седиментогенез, а також мати істотне практичне значення.

content of microelements, such as zinc, manganese, molybdenum, copper, cobalt, boron, which stimulate growth and ensure the healthy functioning of plants. Therefore, the most widespread and promising may be the use of glauconite in agriculture, primarily as potash fertilizer and ameliorant. It is one of the most common minerals of the pre- Cenozoic sedimentary stratum of the Dnieper- Donets depression. There are no significant concentrations of glauconite in the Paleozoic sediments. In Mesozoic sediments, the mineral is present in the formations of all three systems. Among sediments of the Jurassic system, high concentrations of the mineral are observed in the Kimmeridgian layer. Among the sediments of the Cretaceous system, significant concentrations of glauconite are present in the formations of the Albian and Cenomanian layers. On the Erathem scale, an increase in the content and mass of glauconite from the Paleozoic to the Mesozoic is observed. On the scale of the systems, an increase in the bulk mass of glauconite is observed in the direction of the Perm → Triassic → Jurassic → Cretaceous. At the lithological level, the most promising types of rocks of all layers are sands, less commonly silts, clays, and sandstones. At the stratigraphic level, the Cenomanian sediments are the most promising. In the horizontal plane, the most promising are the pit edge parts of the depression. In general, the wide distribution of promising layers of the Mesozoic indicates the unlimited mineralogenic potential of the depression on the glauconite raw materials. But the extraction from these sediments in the near future makes it difficult to deeply occur, insufficient capacity for such depths, location mainly under arable land or settlements. With the improvement of depth mining technologies, the use of this resource in the more distant future cannot be ruled out. This primarily concerns the joint manifestations of phosphorites and glauconite in the Mesozoic sediments.

For reliable operation of engineering objects during designing it is proposed to take into account not only faults in their density within the unit of area but also within the block structures to allocate zones with microgeodynamic processes, where there are sharp changes in humidity, mechanical, thermal and electrical energy.

113 ВВЕДЕНИЕ Количественный рентгеновский микроанализ длинноволновых линий (Кα-линий) легких элементов (Be, B, C, N, O и F) связан со значительными трудностями, которые вызваны тем, что при измерении длинноволнового низкоэнергетического (≥12Å и ≤1 кэв) рентгеновского излучения велико поглощение первичного излучения и общепринятые модели поправок для анализа легких элементов могут не работать. Такое низкоэнергетическое излучение регистрируется кристалл-дифракционными (волновыми) спектрометрами с использованием кристаллов с большим межплоскостным расстоянием d, в то время как для энергодисперсионных спектрометров анализ легких элементов осложняется наличием в спектре линий более тяжелых элементов и необходимостью учитывать наложение рентгеновских линий, а также смещение линий за счет химической связи (Гоулдстейн и др., 1984). На результаты количественного анализа оказывает также влияние загрязнение образца углеродной пленкой, полимеризующейся на поверхности образца из остаточных масляных паров в камере образца под воздействием электронного пучка, а также используемые при проведении количественного анализа эталоны. Рентгеновские эмиссионные спектры для легких элементов состоят из одной полосы, определяемой переходом валентного электрона на вакансию в К-оболочке.
