(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)Results of magnetotelluric tests, carried out in Siberian kimberlite province, are examined from the viewpoint of structural control over location of kimberlite fields and bunches of kimberlite pipes. It is demonstrated ...
-
(1996)The results of deep electromagnetic soundings for the active transition ocean-continent zone at Sakhalin Island are presented. After an averaging procedure of the magnetotelluric response functions, the period range was ...
-
(2002)An eccentric loading approach was applied to quantify confinement effects and examine the energy balance in a slab under buckling load. It was indicated that confining pressure provided by fill or broken rock material can ...
-
(1997)The stoichiometry of pyrite dissolution by Fe(II) ions was studied in chloride media around pH 2. Pyrite was found to dissolve nonstoichiometrically during the initial tens of hours and a S-rich layer was formed on the ...
-
(2001)In-solution atomic-force microscopy was used to characterize molecular dimensions and aggregate structures of natural organic matter (NOM) sorbed to the basal-plane surfaces of muscovite and hematite as a function of pH ...
-
(2003)Mineral dissolution rates have been rationalized in the literature by surface complexation models (SCM) and morphological and geometric models (GM), and reconciliation of these conceptually different yet separately highly ...
-
(2004)Biostratigraphical study of the early to mid-Ordovician conodont fauna from ribbon-banded radiolarian cherts of the middle Burubaital Formation in Central Kazakhstan reveals an almost complete succession of conodont biozones ...
-
(2002)This study is to clarify the geologic time of the Dumugol Formation in the Tanyang area on the basis of conodonts. A total of 245 identifiable conodonts were recovered from 56 samples. They are classified ...
-
(2001)The task of this paper is to discuss the Frasnian Stratigraphy of the central region of the Russian Platform; to analyse the distribution of the most abundantly occurring platform conodonts: to revise the zonal schemes ...
-
CONODONTS IN XENOLITHS OF SEDIMENTARY ROCKS FROM KIMBERLITE PIPES OF THE DALDYN-ALAKIT AREA (SAKHA) (2003)Diverse conodont assemblages discovered in xenoliths of sedimentary rocks from kimberlite pipes are analyzed and correlated with zonal stratigraphic scales. Based on the original and published data, a Paleozoic rock sequence ...
-
(2001)A numerical cladistic analysis of the conodont family Palmatolepidae has been undertaken to determine the applicability of the technique to group-wide systematic revision. Results suggest a new hypothesis of relationships ...
-
(1988)Fields of granitic pegmatites containing rare metals in industrially important Precambrian zones are accompanied by regional zones of hydrothermally-altered rocks containing high concentrations of hydromagmatophilic elements ...
-
(2002)Magmas erupted at mid-ocean ridges (MORB) result from decompression melting of upwelling mantle. However, the mechanism of melt transport from the source region to the surface is poorly understood. It is debated whether ...
-
(Общество с ограниченной ответственностью «Георесурсы», 2018)The article is devoted to the study of replenishment of oil reserves in long-developed fields and contains a substantiation of the need for its monitoring and control. This will allow for a new approach to modeling the ...
-
CONSIDERATION ON THE OCCURRENCE OF THE AL13 POLYCATION IN NATURAL SOIL SOLUTIONS AND SURFACE WATERS (2001)Equilibrium speciation calculations were performed (1) for soil solutions and streamwaters collected in central and eastern France and (2) for simulated waters at 0 and 25°C, to assess the highest concentration of Al13 ...
-
(2001)This paper considers the factors that influence ground CO2 fluxes as measured by the chamber method. New data and published results are used to illustrate the effects of various factors on CO2 emissions from the ground. ...
-
(1990)A "double dipole" model with a zero moment was first used to describe faults in an earthquake focus by Honda and Vvedenskaya [l]. But until recently, publications dealing with alternative models continued to appear [2]. ...
-
(1990)The existence of anomalously high heat flows near the surface would make it fundamentally impossible to solve the inverse problem of geothermometry, i.e., the determination on the basis of the heat flow, of the temperatures ...
-
(2004)A disadvantage of fully non-linear methods of inversion, through exploitation of the properties of model space, is the absence of a well-developed framework for error assessment. To rectify this problem an auxiliary weighting ...
