-
(2004)The paper attempts to identify ionospheric parameters in association with earthquake at anomaly crest station through VHF Radio Beacon data and ground based ionosonde measurements while the Total Electron Content(TEC) ...
-
(2003)Citric acid is found along with uranyl in the subsurface of former nuclear facilities because of its use as a decontamination agent in the nuclear industry. Citrate's metal chelating properties affect the mobility of uranyl ...
-
(1999)The speciation and molal formation quotients for the complexation of aluminum with sulphate were measured based on potentiometric and solubility experiments. Potentiometric titrations, utilizing a hydrogen-electrode ...
-
(1989)Peri-fault metasomatites of the associational types discussed differ in chemical bias or specialization (Table 1). The subalkalic feldspathic metasomatites containing lepidomelane tend to concentrate Be, Nb, Ta and the ...
-
(1987)This article describes Cenozoic basaltic rocks in the Sea of Japan. Analysis of a large body of data leads to a division of them into natural associations of volcanic rocks and specific geochemical types. Their classification ...
-
(2004)The platinum-group minerals (PGM) and chromite composition of the Zolotaya River gold placer, in the Russian Far East, indicate a genetic relationship to poorly exposed Late Permian dunite - hornblendite - gabbro intrusions ...
-
(1989)Current theories on ore associations are based on mineralogical and geological features of ore deposits, and also on the sets of elements present in specific ores. The classification of deposits in terms of the trace ...
-
(2008)An explosive eruption occurred at Bezymianny Volcano (Kamchatka Peninsula, Russia) on 24 December 2006 at 09:17 (UTC). Seismicity increased three weeks prior to the large eruption, which produced a 12–15 km above sea ...
-
(1988)In this article, by asthenosphere we mean a relatively low-viscosity layer, formed in the upper mantle because the temperature there approches the solidus temperature of rocks at those depths. If the mantle temperature ...
-
(1999)Essentials of Milankovitch theory are considered in order to reveal its consistency with paleoclimatic and astronomical data obtained during the last 30 years. Numerical data calculated by Milankovitch are shown to be ...
-
(2004)A new superorder of Paleozoic ectochochlian cephalopods, Astrovioidea superordo nov., is designated. A distinctive feature of this superorder is that the soft cameral tissue enters the siphon cavity and secrets calcareous ...
-
(2014)Avacha group includes two active and potentially dangerous volcanoes, Avachinsky and Koryaksky, located close to Petropavlovsk-Kamchatsky, the main city of Kamchatka. We present the results of two independent seismic studies ...
-
(2003)The Eocene to middle/late Miocene tectonic evolution of the Kuril arc and backarc region has been simulated with analogue experiments. The experiments simulate asymmetric deformation in the overriding plate due to anticlockwise ...
-
(1997)The geomagnetic reversal chronology shows a decreasing reversal rate, λ, from about 160 Ma to about 118 Ma, a cessation in the reversal process (the Cretaceous Normal Polarity Superchron) until about 83 Ma, and then an ...
-
(2002)Asymptotic bias in large quantiles and moments for four parameter estimation methods, including the maximum likelihood method (MLM), method of moments (MOM), method of L-moments (LMM), and least squares method (LSM), is ...
-
(2002)Satellite laser ranging (SLR) and lunar laser ranging (LLR) systems are single-ended instruments, i.e. they measure the roundtrip transit time of a laser pulse to a passive optical reflector. Since such single-ended systems ...
-
(2002)Existing flow resistance relationships for mountain rivers may be in error by typically 30%. In part this is because flow resistance is a complex phenomenon, not easy to quantify with the available data. However, a further ...

(PANGAEA, 2006-03-17)
-
(2003)The mineral zircon is extremely variable both in terms of external morphology and internal textures. These features reflect the geologic history of the mineral, especially the relevant episode(s) of magmatic or metamorphic ...
