(1981)The relationship between recent crustal movements and evidence of seismicity on the active Turanian plate has been inferred by the author in 1966 from the results of integrated seismological and strain-metering investigations. ...
-
(2003)The slip instability of an earthquake and its abrupt energy release depend primarily on the intensity of strength drop during accelerated fault slip. This process is typically attributed to changes of frictional resistance ...
-
(1995)Four density fractions of interstellar graphite were analyzed for isotopically anomalous noble gases by stepped heating. As in SiC, the dominant components show the signature of the s-process and apparently come from AGB- ...
-
(1998)Ion probe determinations of water concentrations and D/H ratios have been performed on different phases (pyroxene, olivine, and mesostasis) of chondrules from the Bishunpur and Semarkona LL3 chondrites. Mean water ...
-
(2004)Small amounts of interstellar grains which survived processes in the protoplanetary nebula were identified in carbonaceous and unequilibrated chondrites. The stellar origin of the diamond, graphite, SiC, and corundum grains ...
-
(1995)D/H ratios of two meteorites (Renazzo CR and Semarkona LL3), which are known to exhibit the largest departures from the terrestrial hydrogen isotopic ratios, have been determined with the CRPG Nancy ion microprobe. ...
-
(2000)The inflow of 137Cs, 90Sr, 239,240Pu, and 241Am to interstitial solutions was studied in organic and mineral soils that are abundant in the region of Belarus subjected to the consequences of the Chernobyl accident. The ...
-
(2001)This paper presents a test of a very simple model for predicting beach slope changes. The model assumes that these changes are a function of both the incident wave conditions and the beach slope itself. Following other ...
-
(2002)During the evolution of continents, compressive tectonic phases can leave certain tectonic patterns in the lithosphere to be observed by reflection seismology. Also, in the area of the trans-European suture zone (TESZ) in ...
-
(2001)We measure the factors that determine growth rate (temperature, drip rate, calcium ion concentration) for 31 waters that feed stalagmites within six cave systems throughout Europe. Water samples were collected at a frequency ...

-
(2003)Intra-oceanic arcs are the simplest type of subduction,systems in that they occur where overridding plates of subduction zones consist of oceanic rocks, contrasting with arcs built on continental margins. They comprise,some,40% ...
-
(1989)As is well known, intracontinental seas with oceanic-type crust, such as the Caspian, Black, and Mediterranean seas located within the Alpine-Himalayan fold belt, are among the most enigmatic of geological formations. A ...
-
(1996)Thermal dehydroxylation and partial fluorination techniques were used to measure intracrystalline fractionation of oxygen isotopes between hydroxyl and non-hydroxyl sites in kaolinite. Several aliquots of a well characterized, ...
-
(1996)Intracrystalline REE distributions in fluorapatite have been studied using cathodoluminescence and synchrotron X-ray fluorescence microanalysis (SXRFMA). In the apatite samples studied the {1010} face grows by the spiral ...
-
(2003)Intragranular microshear zones within a greenschist facies calcite marble were studied to try to constrain better the processes of dynamic recrystallization as well as the deformation processes that occur within newly ...
-
(1989)A whole series of observations indicates that intramineralization transformations have an important effect on ore emplacement, but suitable methods of identifying them and estimating their scale have not yet been adequately ...
-
(1999)The main features of the geology and petrology of anorthosite-rapakivi granite complexes (ARGC) are discussed, using the Proterozoic (1.76-1.5 Ga) granite massifs of the Baltic and Ukrainian shields as the examples. According ...
-
(2004)Synthesis of petrological, geochemical, and isotopic data on volcanic rocks and a related suite of xenoliths in the De Long Islands in the eastern sector of the Arctic basin is presented with the aim of reproducing the ...
