    No evidence of extraterrestrial noble metal and helium 01-03-2016· High concentrations of extraterrestrial iridium have been reported in terminal Sturtian and Marinoan glacial marine sediments and are used to argue for long (likely 3-12 Myr) durations of these Cryogenian glaciations.No evidence of extraterrestrial noble metal and ,2016-3-1 · Extraterrestrial matter is enriched in Ir ∼10 000-fold compared to average eolian dust, upper continental (Kurat et al., 1994, Peucker-Ehrenbrink and Jahn, 2001) and oceanic (Peucker-Ehrenbrink et al., 2003, Peucker-Ehrenbrink et al., 2012) crusts. Iridium therefore serves as one of the most sensitive refractory tracers for the presence of ET matter in sediments.

    This is conclusive evidence for a five Rayleigh value at night. This is conclusive evidence for extraterrestrial helium emission. For 304 A radiation, the intensity decreases from a maximum in the daytime near the magnetic equator toward both poles, dropping sharply near 55 degrees magnetic latitude and reappearing at that latitude.

    2016-3-1 · New platinum group element concentrations, and 187 Os/ 188 Os and 3 He/ 4 He signatures are consistent with crustal origin and minimal extraterrestrial contributions. The discrepancy is likely caused by different sample masses used in the two studies, with this study being based on much larger samples that better capture the stochastic distribution of extraterrestrial particles in marine sediments.Extraterrestrial Helium in Seafloor Sediments,Helium isotope systematics uniquely identify the extraterrestrial component, which is apparently hosted within magnetite and silicate grains. In some sediments 3 He is completely derived from this source, in others the extraterrestrial fraction can be computed from the measured 3 He/ 4 He ratio.
