The paper discusses integrated sequence-cyclostratigraphic analysis of Upper Cretaceous sediments based on 9 sections in the Russian Plate (the Voronezh Anteclise and the Ulyanovsk-Saratov Basin). Tracts (transgressive and highstand) were for the first time recognized in sections of this region and compared with member-by-member subdivision, bed rh...

Geological and geochemical data on Neoproterozoic and Early Paleozoic metamorphic and igneous complexes of East Antarctica are considered. Sedimentation and formation of mafic dikes in the Neoproterozoic point to dominant extension through most of the Antarctic Shield, although no indications of advanced rifting and opening of deep basins have been...

The problems of epignostic analysis of groundwater intake well operation are considered. The disturbance of interaction conditions between underground and surface waters in connection with damage caused to river runoff were revealed according to the data of monitoring observations during long-term operation of a riverain water intake well. The hydr...

The paper discusses new data resulting from petrographic examination of the composition and structure of Cenozoic sediments penetrated by Well 10 to a depth of 2350 m in the Upper Telekai oil-and-gas field within the Anadyr Basin. An alluvial-deltaic sedimentation environment of tuffaceous-sedimentary and terrigenous producing Lower Miocene rocks w...

An attempt has been undertaken to examine time series of volcanic and seismic events in a multidimensional reference system related to the parameters of the Earth’s orbital motion. Volcanic eruptions and strong (M > 5) earthquakes (a sample from the USGS/NEIC seismological database: Significant Worldwide Earthquakes) [18] were analyzed within the f...

The basin of Bohai Bay is formed by numerous large and small blocks of the earth’s crust submerged to different depths along large faults. Depressions occur along submerged limbs of the largest blocks, which are depocenters of sediment accumulation, mainly for deep water sediments. Eighty depressions are located in this territory, which measures 20...

The Chin Shan porphyry copper-gold deposit is located in the south of China in Fujian province. This is a large deposit containing more than 1000 t industrial reserves of gold and more than 0.5 mln. t of copper. It is related to a very complex polygenic and polychronic type of porphyritic plutonogenic hydrothermal deposits formed during the final s...
