GEOLOGICAL AND GEOCHEMICAL COMPARISON OF SOUTHERN URALS AND SOUTH INDIAN CRYPTOCRYSTALLINE MAGNESITE (2004)South Indian and Southern Urals cryptocrystalline magnesites, deposited in similar geological milieu, are broadly comparable in mineralogy and geochemistry. Magnesite mineralisation in South India is mostly associated with ...

GEOLOGICAL AND GEOCHEMICAL CONTROLS ON THE SILVER CONTENT (FINENESS) OF GOLD IN GOLD-SILVER DEPOSITS (1991)A compilation of microprobe fineness data and a re-evaluation of bullion production fineness data suggest that the gold fineness model of Fisher (1945) can be updated and applied to a wide range of gold-mineralised ...
-
(2003)Specific porphyraceous biotite-amphibole granites considered rapakivi-like according to texture and rock and mineral compositions have been distinguished among granitoids in the eastern Hovsgol region. The granites are ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2019)Major accidents at OJSC Uralkali raised the question of the need for a detailed study of the geological structure of the Verkhnekamskoye potassium salt deposit, the identification of anomalous complex zones in the oversalt ...
-
(2002)This paper describes the Late Precambrian geologic complexes from the southern margin of the Siberian Craton, associated with the extension epochs. Analysis of the data available suggests that there were two episodes of ...
-
(1996)A classification of geological engineering structures is presented. The hierarchy of such structures is as follows: geological engineering superstructure; megastructure; macrostructure; mesostructure. The taxonomic division ...
-
(2003)The central Pamirs (CP) as an element of the Alpine Afghanistan-Central Pamir-Tashkurgan Fold System (Fig. 1) is characterized by diverse and multistage sedimentation, magmatism, and metamorphism spanning a wide ...
-
(1999)A currently emerging sulfur isotope record for Phanerozoic seawater, based on structurally substituted sulfate in stratigraphically well constrained biogenic carbonates, allows the detailed assessment of secular variations ...

(Днепропетровский национальный университет им. Олеся Гончара, 2018)The geological position of the riebeckite metasomatites at the Pervomayskoye, Annovskoye, Gleyevatskoye, Valyavkinskoye, Inguletskoye, Petrovskoye and Artemovskoye deposits of the Krivbas is controlled by faults serving ...
-
(2004)Geological information can be used to solve many practical and theoretical problems, both within and outside of the discipline of geology. These include analysis of ground stability, predicting subsurface water or hydrocarbon ...
-
(2001)Some specific features of the geological structure and ore mineralogy of the Khakandzha silver and gold deposit are discussed. The main ore masses are accumulated in complex, gently inclined, veined metasomatic zones. The ...
