(Appendix A) Helium isotope concentrations and ratios for leached replicates ...
To maximize the size of the samples analyzed, aliquots of 2 to 3 g were leached in 10% acetic acid for 6 h to remove CaCO3. This resulted in residues of about 250 mg of... -

(Table 1) Helium and Thorium 230 excess concentrations in sediment cores B18 ...
At four sites in the central equatorial Pacific Ocean the flux of extraterrestrial 3He, determined using the excess 230Th profiling method, is 8 * 10-13 cm3 STP/cm**2/ka. This... -
(Table 1) Helium isotope ratios of sediment core TT013_114
We present a helium isotope record for core TT013-114PC from the central equatorial Pacific (140°W, 4°N, 4432 m water depth) spanning a period of 1 million years. We focus on... -

Studies on He isotope ratios of gas and rock samples in various parts of the world have shown a close relation between the 3He/4He ratio and geotectonic features of the sampling... -
(Table 1) Helium isotope ratio of ODP Site 198-1209 sediments
We attempt to constrain the variability of the flux of extraterrestrial 3He in the Paleocene by studying sediments from Shatsky Rise (Ocean Drilling Program, ODP Leg 198) that... -
Isotopic-geochemical features of spontaneous gases from mud volcanoes in East...
Isotopic-geochemical study revealed presence of mantle He (3He/4He up to 223x10**-8) in gases from mud volcanoes of Eastern Georgia. This fact confirms that the Middle Kura... -
(Table 1) Helium concentration and flux in DSDP Hole 94-607 samples
Most of the helium-3 in oceanic sediments conies from interplanetary dust particles (IDPs), and can therefore be used to infer the accretion rate of dust to the Earth through... -
