Helium - Wikipedia

Helium (from Greek: ἥλιος, translit. Helios, lit. 'Sun') is a stone element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas, the first in the noble gas group in the periodic table.

Extraterrestrial Helium in Seafloor Sediments ...

Extraterrestrial He is carried to the seafloor by the finest fraction of interplanetary dust and is retained in at least some sediments for hundreds of millions of years. Helium isotope systematics uniquely identify the extraterrestrial component, which is apparently hosted within magnetite and silicate grains.

Impact Event at the Permian-Triassic Boundary: Evidence ...

2001-02-23 · The ET signature of the helium provides strong evidence that the PTB fullerenes were delivered intact to Earth in a bolide (asteroidal or cometary) at the PTB. To confirm that the increase in the fullerene component at the PTB results from an impact and not from a change in the sedimentation rate at the boundary, we examined the 3 He concentration in the bulk Sasayama sediments at several ...

The use of helium-3 as a constant-flux proxy of sedimentation rate implies deposition of the K-T boundary clay in (10 ± 2) × 10^3 years, precluding the possibility of a long hiatus at the boundary and requiring extremely rapid faunal turnover.

Is "Primordial" Helium Really Extraterrestrial? K. A. Farley . Among the isotope systems exploited by mantle eeochemists to deduce the stone " evolution of the Earth, those of the rare gases are unique because they record the migration of volatile species from the mantle to the atmosphere. The isotopic composition of helium in mantle-derived rocks is now rea- sonably well known, and it ...
