-
(2000)The standard chemical potentials μso of aqueous solutes over a wide range of temperatures and pressures are needed to calculate phase and chemical equilibria in hydrothermal systems. The standard derivative thermodynamic ...

-
(PANGAEA, 2018-09-25)Here we quantify the abundance and distribution of three primary permafrost region disturbances (PRD; lakes and their dynamics, wildfires, retrogressive thaw slumps) using trend analysis of 30-m resolution Landsat imagery ...
-
(2000)We present a summary of the methodology for probabilistic fault displacement hazard and discuss the types of data needed for the analysis. The methodology is based on the widely used formulation for probabilistic assessment ...

-
(1997)A data processing and storage system for records of wave disturbances in the atmosphere generated by volcanic eruptions is described. The system was developed using acoustic signals recorded during eruptions of Kamchatkan ...

(PANGAEA, 1998-10-06)In this thesis it is shown that the cosmogenic radionuclide 10Be proved to be a sensitive stratigraphic tool for sediment cores from the Arctic Ocean with low or negligible content of biogenic carbonate, impeding a reliable ...
-
(2000)Alteration of submarine basalts compromises geochronology using conventional K/Ar and 40Ar/39Ar techniques. To help overcome these problems, we re-evaluated the potential of groundmass dating techniques. Incremental heating ...
-
(2003)The long-term rate of racemization for amino acids preserved in fossil ostracode shells was determined by using independently dated sediment cores from five deep lakes. The racemization rates for aspartic and glutamic acids ...
-
(2003)Dating of metamorphic processes is difficult due to genetic heterogeneity of metamorphic rock. Problem of dating is often connected with long and multistage proceeding of metamorphism. Time of process is determined by ...
-
(2004)This work is an attempt to determine the real time of formation of coastal-marine placers based on the modeling of placer-forming processes, present-day rates of lithodynamic processes, and recent parameters of placer ...
-
(2003)Garnet peridotites from the Kokchetav ultrahigh-pressure (UHP) massif contain abundant volatile and high field strength element (HFSE) bearing minerals, such as Ti-clinohumite and zircon. These characteristics are interpreted ...
-
(2001)Dating sediment burial over million-year time scales is crucial in many areas of the Earth sciences and archeology, but is often difficult using traditional techniques. Sediment burial can be dated by the radioactive decay ...
-
(1986)This paper is a review of well-documented geochronological and related isotopic evidence for the age and total crustal residence time of the oldest known terrestrial rocks, mainly using Rb/1bSr, Sm/1bNd and U/1bPb decay ...
-
(2003)Applications of luminescence dating of geological materials have undergone extensive development and refinement since 1974 when Wintle first attempted to date volcanic lava using thermoluminescence (TL). Today, luminescence ...
-
(1990)In 1985 for the first time in eastern Siberia, while studying the mineralogy and the geochemistry of the area around the Zharchikhinskoye molybdenum deposit in the central ore district, Buryat ASSR, we found and later ...
-
(2002)The Davydovskii ultramafic-gabbro massif in the eastern Central Urals (about 100 km east of the Platinum-bearing belt) has been studied in detail. The rock suite (dunite, clinopyroxenite, and gabbro) and chemical characteristics ...
