Recent experimental studies on unlithified sediments suggest that the compaction is in part viscous. At the basin scale and on a geological time scale, processes such as pressure solution can be approached by creep ...

Global variations of the radionuclide 10Be that are almost simultaneous provide a powerful tool to synchronize 10Be records from different locations. We compared the 10Be record of the Akademii Nauk (AN) ice core (Russian ...

In the previous chapters we have argued that cohesive sediment contains various materials, such as sand, organic residue of plants, and sometimes contaminants. The organic matter is degraded under aerobic (top ~ ...

More than 200 000 ring-width measurements from 384 trees were obtained for 20 individual sites ranging from the lower to upper local timber-lines in the Northwest Karakorum of Pakistan and the Southern Tien Shan of Kirghizia. ...

133Cs MAS NMR of Cs-exchanged illite, kaolinite, boehmite, and silica gel is shown to be a powerful tool to investigate the adsorption sites and atomic dynamics of Cs on mineral surfaces. Cesium is adsorbed on these mineral ...

13C-enriched glasses of albite, nepheline, and sodamelilite compositions were quenched from melts at 1350–1625°C and 10–35 kb, and studied using 13C and 27A1 MAS NMR. Distinct resonances for molecular CO2 and carbonate ...

Now-extinct 146Sm (t1 = 103 Ma) was present in the early solar system, and lunar basalts might be expected to have inherited small anomalies in 142Nd abundances from mantle sources with variable Sm/Nd ratios established ...

Prompted by the finding that the eucrite Piplia Kalan could have retained Pu fission Xe earlier than the eucrites so far studied and hence be very ancient, we have measured a precise internal 147Sm-143Nd isochron for this ...

Kamchatkan Volcanic Eruption Response Team (KVERT), created in 1993 through a cooperative effort of Russian and U.S.A. scientists, analyses the data of monitoring of Kamchatkan and Northern Kurile volcanoes to provide ...
