The possible use of carbonate rocks from some Karelian deposits for the production of correcting additives to raw cement blend from cement occurrences in the Leningrad and Novgorod districts (exemplified by the Babino occurrence) with insufficient standards for unaided exploitation are discussed.

Abstract In the area of carbonate or karst Dinarides, besides the dominant carbonate rocks and subordinate clastics, in more places more significant mass of chemical sediments can be found, represented by gypsum and anhydrite. As chemical sediments are specifically lighter than overlying rocks, they have been, during the long geological history, trying to achieve isostatic equilibrium, or get out on the ground surface. In recent times, in areas with chemical sediments, a larger tectonic activity is noted than in the wider environment. This is certainly reflected in increased vertical and tangential displacements along major faults in relation to the surrounding area, which are built mainly of carbonate deposits. Determining the amount of movement of diapiric bodies, as absolute and relative, using the most modern surveying methods, precisely would assist the understanding of the tectonic movements and recent structural relations in a wider area

While the characteristics and origin of drusy calcite cement in carbonate deposits is well constrained in the literature, little attention is paid to drusy dolomite cement. Petrographic observations, stable isotopes, and fluid-inclusion microthermometry suggest that drusy dolomite cement in Permo-Triassic conglomerate/breccia dolostone beds in northern United Arab Emirates has precipitated as cement and not by dolomitization of drusy calcite cement. The low 18OVPDB (−9.4‰ to −6.2‰) and high homogenization temperatures of fluid inclusions in drusy dolomite (Th = 73–233 °C) suggest that dolomitization was caused by hot basinal brines (salinity = 23.4 wt% NaCl eq.). The 13CVPDB values (+0.18‰ to +1.6‰) and 87Sr/86Sr ratio (0.708106 to 0.708147) indicate that carbon and strontium were derived from the host marine Permo-Triassic carbonates. Following this dolomitization event, blocky calcite (Th = 148 °C; salinity = 20.8 wt% NaCl eq.) precipitated from the hot basinal brines. Unravelling the origin of drusy dolomite cement has important implications for accurate construction of paragenetic sequences in carbonate rocks and decipher the origin and chemistry of diagenetic waters in sedimentary basins.

The article considers the wells that have penetrated the carbonate sediments with the geological and paleontological information. By the late Devonian epoch paleogeographic scheme they are located in certain megazones with their inherent characteristics of sedimentation. Examples of lateral relations of carbonate or shalecarbonate rocks with subordinate volcanic rocks on Lovinsky and Khanty-Mansi areas are given. A variety of types of carbonate rocks is associated with structural features of basins in which there was sedimentation, as well as various secondary processes. Based on new geological information, obtained in recent years on Galyanovsk, South Galyanovsk, Khanty-Mansi and other areas, the areas of distribution of carbonate deposits within the Frolovskaya megadepression are clarified. Their petroleum potential is associated with reef structures is mostly confined to near rim parts of the deep depressions of the basement, a reliable mapping of which is possible with more detailed geophysical work.
