Biostratigraphy of the Middle Paleozoic of Guinea
- Authors:
- F. Conde
Middle Paleozoic sediments are widespread in the territory of the People's Revolutionary Republic of Guinea and form the West Guinea Syneclise, or Bove Syneclise. The first data on the distribution of Middle Paleozoic sediments in this part of the African continent were obtained by J. Sinclair, J. Lecointeur and P. Lemoine, and generalized in the works of R. Furon, E. Sheetel and other French geologists ...

Representatives of the genera Saumella and Obisafitella (Ostracoda) from the Lower Devonian of the South Tien Shan
- Authors:
- E. D. Mikhailova
In the Devonian sections of the Southern Tien Shan, a group of ostracods was found, the shells of which have characteristic trapezoidal outlines and a significantly expanded and flattened ventral side. The study of the structure of the free edge of these shells allowed us to distinguish among them two groups, differing from each other primarily by the presence or absence of the internal calcified lamina ...

Materials to the stratigraphy of the Artinskian Stage of the Middle and Southern Urals
- Authors:

We studied the deposits of the Artinskian Stage in two regions of the Urals: in the Middle Urals in the basins of the Yuryuzan, Ufa, Sylva, Kosva and Usva pp.; in the South Urals in the zone of the advanced folds of the Aktobe, Orenburg and South Bashkir Urals

New data on stratigraphy of the Middle Triassic deposits of the Northern Verkhoyanyan area
- Authors:
- V. V. Arkadyev
The Middle Triassic sediments of the Northern Verkhoyanye have repeatedly attracted the attention of researchers. The presence of Anisian sediments in the Kharaulakh Mountains was first established by L. D. Kiparisova on the basis of fauna brought from this area by geologists I. G. Nikolaev and A. I. Gusev ...

New species of colonial Devonian rugosas of Novaya Zemlya
- Authors:
- G. V. Lakhov
The fauna of quadrangular corals from Devonian sediments of Novaya Zemlya is rich and diverse. However, it is described extremely insufficiently and unevenly, both stratigraphically and geographically by A.G. Kravtsov and E. 3. Bulvanker studied mainly solitary forms belonging to the families Tryplasma- tidae, DigonophYllidae, CYstiphyllidae, Zonophyllidae, Heliophyllidae, Stringophyllidae, and to a lesser extent colonial corals of the families Spongophyllidae, Billingsastraeidae, XYstriphyllidae from the Early and Middle Devonian sediments of the South Island ...

New data on the Upper Jurassic foraminifera of Franz Josef Land
- Authors:
- A. R. Sokolov
The Franz Josef Land archipelago is one of the least studied in geological terms areas of the USSR territory. As a consequence, the stratigraphic basis is insufficiently developed, in particular, the study of foraminifera - the main group for determining the age of sediments during drilling. The drilling of boreholes on the archipelago, which has begun in recent years, urgently requires to fill this shortcoming ...

Stages of Early Devonian transgression and dissection of the Lower Devonian of southern Novaya Zemlya.
- Authors:
- R. A. Shchekoldin
The Lower Devonian sediments are widespread in the south of Novaya Zemlya and are well represented in sections of different facies marine strata; this has caused close attention to them by stratigraphers. Over the last quarter of a century, thematic lithologic-stratigraphic studies have been repeatedly undertaken in the south of Novaya Zemlya, in the course of which a unified regional scheme of the Lower and Middle Devonian stratigraphy has been developed and continues to be refined

History of geologic development of the Belbek-Kachinsky interfluve of the mountainous Crimea in the late Valanginian-Albian ages of the Early Cretaceous
- Authors:
- E. F. Dorofeeva
The complexity of the geological development of the Earth's crust within the Mountain Crimea during the Jurassic and Cretaceous periods has been repeatedly noted in the geological literature. In the Belbek-Kachinsky interfluve, the Early Cretaceous history is quite clearly traceable to the end of the Valanginian; the geologic events of the end of the Early Cretaceous are less clearly delineated because of the incompleteness of the stratigraphic section ...

Paleofaunal characterization of Upper Cretaceous deposits of southwestern Crimea
- Authors:
- V. G. Klikushin
The Upper Cretaceous sediments of southwestern Crimea are of considerable interest because in many sections they are well exposed and fully characterized by a variety of fossil fauna. One such section is located in the Belbek River valley. In recent years, extensive material has been collected in this area, allowing not only to detail the dissection of Upper Cretaceous sediments, but also to draw some conclusions about the conditions of their formation and the conditions of existence of Late Cretaceous fauna ...
