Secondary dispersion halos as a prospecting indicator of platinum metal mineralization on the example of the Kamenushinsky massif (Middle Urals)
- Authors:
- A. M. Minibaev
The paper discusses the results of bulk rock geochemical sampling of the Kamenushinsky massif eluvial-deluvial deposits and the massifs bedrocks spectral analysis data. Evaluation of secondary dispersion halos using two-dimensional modeling and multivariate statistic processing of the results have allowed establishing the spatial collocation of platinum and chromium anomalies and high correlation between these elements. These facts confirm the considerable contribution of chromite-platinum mineralization to the primary ores of the entire Kamenushinsky massif. The geological observations and rocks chemical composition analysis has revealed that uranium and barium anomalies are associated with the areas of gabbro and granitoids dike bodies. The insignificant overlapping of uranium and barium anomalies with platinum and chromium ones, as well as the negative correlation between these two groups of elements, is inconsistent with earlier conclusions on the spatial association of platinum mineralization with gabbro and granitoids dikes and a possible connection between these dikes and platinum metal mineralization zones.

G.V.Bogomolov and his role in development of national hydrogeology
- Authors:
- D. L. Ustyugov
- L. P. Norova
In March 2015 the scientific community celebrated the 110th anniversary of the birth of one of the founders of the hydrogeological and engineering-geological school, an honouree of State Award of the USSR and the Byelorussian SSR, Academician Gerasim Vasilyevich Bogomolov. The article is devoted to several important stages of the development of Russian hydrogeology, which are primarily associated with the research conducted by G.V.Bogomolov. His role in the development of hydrogeology in Belarus, i.e. theory and practice of the use of groundwater, is emphasized. This article is about the man who was a brilliant geologist, scholar, lecturer and an outstanding research manager. G.V.Bogomolov founded a school of disciples and followers who continued to develop and put into practice the academician’s ideas in various branches of geological theory and practice.
