Abstract The samples of terrigenous rocks of the Sakhalin were selected for geomechanical studies: the rocks of the Nevelskaya and Kholmskaya Formations from the Petropavlovsk quarry; ones of the Kholmskaya Formation on the west coast of the south of Sakhalin, rocks of the Junonskaya Formation on the east coast. The Kholmskaya Formation N1hl is represented by siltstones and interlayers of fine-grained sandstone. The Nevelskaya Formation N1nv is represented by siltstones with inclusions of tufogenic material. The Junonskaya Formation T2-Jun is represented by variegated greyish-green jaspers. Their static and dynamic parameters (strength limits, static Young’s modulus and Poisson’s ratio, cohesion and angle of internal friction) were determined. The obtained results are characterized by a significant spread of values, which is likely explained by the significant fracturing of the initial samples and the effect of anisotropy.

In the paper the material composition of volcanic-sedimentary Triassic and Permian-Triassic sediments of Severo-Sosvinsky and Sherkalinsky grabens is considered. The scheme of distribution of Triassic and Permian-Triassic sediments of the western territory of Khanty-Mansiysk Autonomous Okrug - Ugra is presented. The sections of the wells, that have revealed the sediments, specific for grabenlike depressions, are described. The oil and gas content of volcanic-sedimentary sediments of Permian-Triassic age in the west of Khanty-Mansiysk Autonomous Okrug - Ugra was analyzed.

This paper is based on a series of experiments on saline soil which is sampled from the west of Jilin province. Through analysis of the properties of material composition, we reveals the inner connection between the dispersivity of saline soil and the soil’s practical environment and material composition, which has theoretical and practical significance in engineering practice and study of saline soil’s dispersivity in this area .This paper will help us fully understand the characteristics of dispersive saline soil and the way it behaviors in engineering for taking the feasible engineering countermeasures to cope with saline soil and engineering accidents caused by the dispersivity of saline soils. The results of this paper will bring engineering applications of dispersive saline soil to a new level.

This paper presents a fresh reading of a significant early medieval recumbent stone monument from West Kirby, Merseyside (formerly Cheshire). Rather than being a single-phased hogback, later subject to damage, it is argued that West Kirby 4 might have been carved in successive phases, possibly by different hands. It is suggested that the carvers had different abilities and/or adapted their work in response to the time pressures of a funeral or a shift in the location or function of the stone. While a single explanation for the character of the West Kirby monument remains elusive, the article proposes that, rather than ‘clumsy and illogical’, the stone was more likely a coherent but experimental, distinctive and asymmetrical, multi-phased and/or multi-authored creation. Through a review of the monument’s historiography and a reappraisal of the details and parallels of its form, ornament and material composition, the paper reconsiders the commemorative significance of this recumbent stone monument for the locality, region and understanding of Viking Age sculpture across the British Isles. As a result, West Kirby’s importance as an ecclesiastical locale in the Viking Age is reappraised.

AbstractA new geological map, mostly subcrop, of the Brabant Massif is presented, based on a revised lithostratigraphy of the outcrop area and on recently acquired palaeontological and lithological data from boreholes in the concealed area. New interpretations of magnetic and gravity data are used to extend the lithostratigraphical units into areas with few or no boreholes. A structural model of the western, northern and southern parts of the Brabant Massif is presented. The main anticlinal axis plunges towards the west-northwest, its core comprising Upper Precambrian (?) to Lower Cambrian terrigenous rocks which outcrop in the southeast. To the north of the main axis, younger rocks appear in regular succession, but to the southwest this picture is complicated by the occurrence of a second anticlinal structure and by a subparallel magmatic arc.

The stratigraphic scheme of the Early Precambrian of the Ukrainian Shield bears a number of differences from the traditional regional stratigraphic schemes: 1) along with stratified subdivisions it includes intrusive and ultrametamorphic complexes that are not accounted for in the “Stratigraphic Code of Ukraine”; 2) The leading role in creating the regional stratigraphic scheme was played by isotopic dating results; 3) The Stratigraphic Scheme does not include the taxon “complex”, as it is described in the “Stratigraphic Code of Ukraine”. According to “Stratigraphic Code of Ukraine”, “Complex” is the largest regional stratigraphic unit that corresponds to a large geo-historical period. Due to the absence of the taxon of “complex” in the regional Precambrian stratigraphic scheme, the main stages of geological development of the region in the Precambrian have not been identified for the Ukrainian Shield. The first article of the cycle is devoted to the feasibility of introducing the taxon of “complex” in the regional stratigraphic scheme on the materials of the Ukrainian Shield. It notes that most of the series in the current stratigraphic scheme correspond to complexes by their level of study and their historical and geological content. Such units are Konkska, Kryvorizka, Teterivska, Ingulo-Inguletska and some other series. Each of them can be separated into several series. The Dniestrovsko-Bugska and Bugska series, the West-Priazovska and Central-Priazovska series of granulite-gneiss complexes are artificially separated and shown as different age subdivisions in the current stratigraphic scheme. These series should be included in the Bug Area and Azov Area complexes, but their volumes and names need clarification. Amphibolite-gneiss complexes can be included in the stratigraphic scheme without dismemberment into series, since they correspond to a large geohistoric stage marked by the peculiarities of their material composition and structural-tectonic position.

In the West Siberia the structural-facies zoning of pre-Jurassic rocks is based on 2 factors: structural and tectonic structure and formation composition of rocks. The central areas of the Uvat district are located within the boundaries of the Tuisko-Barabinskiy facies region, where there are two main points of view on the age of the formations underlying sedimentary cover. Some experts believe that these are rocks of Lower-Middle Paleozoic formations (Caledonides), others believe that these are rocks of Upper Paleozoic-Lower Mesozoic formations (Hercynides). The data obtained from the results of drilling over the past 15 years on the territory of Uvat district on the material composition and the age of pre-Jurassic rocks made it possible to clarify the typical section of these sediments in the Tuisko-Barabinskiy region of facies.
