-
(2001)Isotopic composition of zirconium from eight zircon and two baddeleyite samples including meteoritic zircon have been measured using a laser ablation-multiple collector-inductively coupled plasma mass spectrometer ...
-
(2003)We interpret the shear environments that produced bubble textures in obsidian samples using the results of theoretical, numerical and experimental studies on the deformation of bubbles in shear flows. In particular, we use ...
-
(1995)Glass inclusions in quartz microphenocrysts were analyzed for major and minor elements by electron microprobe and H, Li, Be, B, Rb, Sr, Y, Nb, Mo, Sn, Cs, Ce, Th, and U by ion microprobe. The phenocrysts and inclusions ...
-
(2002)High-frequency (=<2 hz) rayleigh wave phase velocities can be inverted to shear (s)-wave for a layered earth model up 30 m below the ground surface in many settings. given s-wave velocity (vS), compressional (P)-wave ...
-
(1997)In the optical dating of sediments it is usually assumed that the optically stimulated luminescence (OSL) signal has been completely reset by light exposure prior to burial; this assumption is often not valid. One approach ...
-
(2002)The length of day and the geomagnetic field are clearly correlated over decadal periods (10–100 yr). Provided the electrical conductivity of the lower mantle is sufficiently high, a considerable part of this correlation ...
-
(1998)A quantitative thermodynamic model for detonation of metastable accumulations of heavy hydrocarbons ascending from the upper mantle is considered. The Chapman-Jouguet detonation parameters were determined by minimizing the ...
-
(2003)It is well known that vertical head gradients exist in natural aquifer systems, and borehole flowmeter data have shown that such gradients commonly set up spontaneous vertical flows in monitoring wells, often called ambient ...
-
(2014)We report detrital zircon ages for Precambrian and early Palaeozoic metasediments from the Tianshan orogen in Kyrgyzstan, an important component of the Central Asian Orogenic Belt and compare these with published ages from ...
-
(2005)Illite crystals in siliciclastic sediments are heterogeneous assemblages of detrital material coming from various source rocks and, at paleotemperatures > 70 degrees C, of superimposed diagenetic modification in the parent ...
-
(1998)Detrital sediment is carried from land to the sea by three agents, rivers, glaciers, and winds. The shoreline is an arbitrary boundary within the detrital sediment transport system, which extends from a site of origin ...

(Федеральное государственное бюджетное учреждение науки Институт земной коры Сибирского отделения Российской академии наук, 2017)
-
(2003)The composition of “heavy,” or accessory, detrital minerals in sediments and sedimentary rocks has been a topic of quantitative study for at least the last seventy years, beginning with the first issue of the Journal of ...
-
(2001)Soil erosion is commonly measured as the quantity of sediment leaving a plot or watershed. The techniques for measuring soil erosion patterns and sediment redistribution within plots or watersheds by direct monitoring are ...
-
(2005)To ensure the long-time stability of the terrestrial reference system with an accuracy of 10-9 in the global and continental scale, the interactions between different time-dependent influences of the system Earth to the ...
-
(2002)A novel flow-through method for cleaning and dissolving foraminiferal shells is presented. Using automated chromatographic equipment, the system chemically removes contaminant phases from the shells. The cleaned calcite ...
-
(PANGAEA, 2012-04-20)
-
(2001)To better manage aquatic and riparian ecosystems, knowledge of streamflow return intervals is essential. This leads hydrologists and planners to often question how many years of record are necessary to adequately estimate ...
-
(1995)In order to further improve understanding of the behavior of phosphorus in sediments and in the global exogenic cycle, a standardized technique for the determination of phosphorus and associated elements in sediments is ...
-
(2001)One of the most pronounced environmental changes during the Holocene Baltic Sea history was the transition from the freshwater Ancylus Lake to the brackish water Litorina Sea. The establishment of brackish conditions during ...
