(2006)New field, structural, petrologic, and age data show that tectonic styles and metamorphic histories in the West Alldays area of the Central Zone of the Limpopo Complex, southern Africa, can be linked to neo-Archean and ...
-
(2006)We use magnetic intensity data to determine the geometries of basalt-filled rifts of the West Siberian Basin. En echelon graben arrays suggest a component of right-lateral, north-south shear during east-west extension ...
-
(2006)Discontinuity and periodicity of tectonic processes, eustatic fluctuations of the ocean level, volcanic and metallogenic activity, and some other global processes in the Earth's history are indicative of the pulsatory ...
-
(2006)A technique has been developed for pH measurement in flow-through cells at temperatures from 175 to 350°C and pressures up to 350 bars in a nonisothermal cell consisting of a ZrO2(Y2 O3) ceramic electrode and a Ag/AgCl (2 ...

1.8 GA MAGMATISM IN THE FENNOSCANDIAN SHIELD; LATERAL VARIATIONS IN SUBCONTINENTAL MANTLE ENRICHMENT (2006)The ca. 1.8 Ga post-collisional magmatism in the southern part of the 2.1-1.86 Ga Svecofennian domain of the Fennoscandian Shield have been studied with particular reference to the character and sources of the mafic rocks ...
-
(2006)Results of the detailed study of Miocene volcanic ashes from Kerch and Taman peninsulas are presented. Based on the distribution of pyroclastics in the rocks under consideration, the Sarmatian and late Meotian stages of ...
-
(2006)Ontogenetic change in δ18O values of the investigated Nautilus pompilius Linne shell in the Philippines (Tagnan, Panglao Islands, Bohol Island area) confirms data, in which Nautilus in the wild shows a marked increase in ...
-
(2006)Bivalve mollusks are very important in the Permian biota of Northeast Asia. During the Permian the bivalves had different distribution patterns both in space and time, and their occurrence was governed by many factors ...
-
(2006)The Rb-Sr isochron age of igneous ankerite-calcite and siderite carbonatites in central Tuva is estimated at 118 ± 9 Ma. The following ranges of initial values of O, C, Sr, and sulfide and S isotopic compositions were ...
-
(2006)Authigenic carbonates sampled in a complex pockmark (G11) from the Nyegga area, south western Vøring Basin, reveal strikingly different morphologies. A comparative study of macro and micro features of these neighbouring ...
-
(2006)Azimuthal Resistivity Soundings (ARS), using the so-called "Arrow-type array" as proposed by Bolshakov et al. were carried out in Central Tunisia, together with azimuthal resistivity tomography, because of the known ...
-
(2006)We propose a method of surface and marine electrical prospecting using controlled-source excitation. The method is designed to detect hydrocarbon deposits at depths of a few kilometers and to map their boundaries. The ...
-
(2006)The Cretaceous period was generally characterized by greenhouse conditions. Nevertheless, our data on isotopic composition of biogenic carbonates from the Koryak Upland and Sakhalin (Russian Far East) show that during the ...
-
(2006)Vertical Electrical Sounding (VES) method, known from 1912, has changed greatly during the last 10 years, into a new technology named Resistivity Imaging (RI) with 2D data interpretation. Another possible development for ...
-
(2006)The West Siberian Basin is one of the largest intra-cratonic basins of the world and an important hydrocarbon province of Russia. Perhaps the most important geologic event in Siberia was the emplacement of basalts around ...
-
(2006)Pioneer results of the comprehensive analysis of nodules from the Upper Paleozoic coaliferous association and the underlying Middle Paleozoic sequence in the southern Tunguska Basin (Siberian Craton) suggest the following: ...
-
(2006)The paper presents new data on geology of the Curonian Spit based on results of the study of data on the engineering-geological transect compiled during the construction of gas pipe in the Russian sector of the spit. The ...
-
(2006)The Persian Gulf Basin is the richest region of the World in terms of hydrocarbon resources. According to different estimates, the basin contains 55-68% of recoverable oil reserves and more than 40% of gas reserves. The ...
-
(2006)A lithological and palaeomagnetic analysis of Late Weichselian glaciolacustrine deposits from two ancient periglacial lakes was carried out in the valley of the Shuja (S Karelia) and Ust-Pjalka (S-E Kola Peninsula) rivers, ...

GEOELECTRICAL CHARACTERIZATION OF A SITE WITH HYDROCARBON CONTAMINATION CAUSED BY PIPELINE LEAKAGE (2006)Vertical eletrical Sounding (VES) method is used extensively in environmental impact studies including hydrocarbon contamination. In this work, the results of the geoelectrical characterization of a contaminated site caused ...
