<sup>10</sup>Be variation in surficial sediments of the Central Indian Basin
2007, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :While the reactivation of tectonic activity along the fracture zones occurs with geological time, presence of volcanogenic hydrothermal material in the vicinity of seamounts and fracture zones in the Basin [17] suggests that the triggering of volcanic and hydrothermal processes is possible. 10Be concentrations in hydrothermal solutions from sediment hosted environments such as the Guayamas Basin and Escanaba Trough are enriched over ambient seawater and at least an order of magnitude higher than that measured in the hydrothermal fluids from sediment starved East Pacific Rise [19]. Accordingly, ascending hydrothermal fluids will deplete 10Be from the sediments and apparently such a process may have occurred in a sediment section with significant metalliferous/hydrothermal component from a flank of a seamount in the Central Indian Basin (Nath et al. unpublished data) which shows 10Be concentrations comparable to the low values reported here (Fig. 2).
Beryllium geochemistry constraints on the hydraulic behavior of mud volcanoes: The Trinidad Island case
2002, Earth and Planetary Science LettersCitation Excerpt :Leaching of the TD11 Digity mud sample extracts 71% of the total 10Be. This isotopic distribution is similar to that obtained by extraction of the authigenic phase from unaltered deep-sea sediments, surficial sediments in both open ocean and coastal environments [20,31] which typically release ∼75% of the total 10Be but only ∼25% of the total 9Be. By contrast, leaching of TD5, TD16, TD20 and TD21 mud samples only extracts 35±5% of the total 10Be.
