Application of the GRACE satellite mission for solving geological and geographic problems

In this paper we provide a literature review of the geological and geographic problems that were successfully solved via the application of the Gravity Recovery And Climate Experiment (GRACE) satellite mission data. GRACE is a gravitational satellite mission whose purpose is the precise mapping of variations of the Earth’s gravity field. The data have high resolution, which provides the opportunity to solve many geological and geographical problems.     

Instrumental Determination of the Earth’s South Magnetic Pole Position During the Round-the-World Antarctic Expedition on Board the Russian Navy ORV Admiral Vladimirsky

The Field of Attraction of a Polyhedron and Polygonal Plate with Linear Density

New representations of the elements of the fields of attraction (potential and its first derivatives) are presented for the important approximating models such as polyhedron and polygonal plates with the density varying by the linear law. It is shown that these elements are determined through the elements of the fields from the models with the known analytical representations (polyhedron, polygonal plate, and material segment with constant densities) and the additional integrals for which the explicit analytical expressions exist.     

The results of gravity surveys at geophysical grounds in the Kaluga region

The scientific educational practice on gravimetry for the second-year students of the geophysical specialty in 2012–2013 was executed in Central Russia (Kaluga region, the Village of Aleksandrovka). It allowed us to provide an educational process with modern high-precision gravimeters and to fully preserve the curricula and to add elements of topography and geodesic practice. Over these 2 years reliable facts and data were received, which illustrated the possibilities of high-precision gravity measurements in studying the sedimentary cover features of a geological structure.     

Peculiar features of ore composition of the Upper Kingash PGE-Co-Cu-Ni deposit (Krasnoyarsk Territory)

Copper-nickel deposits are abundant sources of cobalt and noble metal mineralization and there-fore attract great attention from both scientists and manufacturers. This investigation is concerned with the new Upper Kingash copper-nickel deposit. This article discusses the results of the examination of ore compositions and the interrelation of ore minerals and the distribution of platinum group elements, cobalt, and nickel in the ores of the Upper Kingash deposit.
