Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes
noble gases solubility degassing silicate melts
2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
Stable and noble gas isotopic study of thermal and groundwaters in northwestern Hokkaido, Japan and the occurrence of geopressured fluids
geopressured fluid hydrogen isotope oxygen isotope helium isotope Hokkaido
2017/8/9
Thermal and groundwaters are distributed along the west coast and in the inland region of Northwestern Hokkaido, Japan. The waters in the latter group have relatively high temperatures. Stable (D, O) ...
Noble gas mass spectrometry with a compressor driven recycling system for improved sensitivity
noble gas geochemistry compressor turbo molecular pump
2017/8/9
In order to increase the sensitivity of static-mode noble gas mass spectroscopic analysis, we have developed and tested a gas re-circulation system, which uses a commercially available turbo molecular...
Noble gas signature of the late heavy bombardment in the Earth's atmosphere
Noble gas signature late heavy bombardment Earth's atmosphere
2009/10/22
The Lunar cratering record is consistent with the occurrence of a late heavy bombardment (LHB), which marked the end of terrestrial planet accretion 3.8 billion years ago. However, clear evidence of a...
Iridium concentration and noble gas composition of Cretaceous-Tertiary boundary clay from Stevns Klint, Denmark
K-T boundary, iridium, noble gas
2017/8/10
The Cretaceous-Tertiary (K-T) boundary about 65 million years ago records a mass extinction event caused by a bolide impact. K-T boundary clay collected from Stevns Klint, Denmark was investigated in ...
On the degassing state and the chemical structure of the Earth's interior inferred from noble gas isotopes—Past and recent views
Earth's interior degassing state noble gas isotopes undegassed reservoir non-convective mantle
2017/8/10
The degassing state of the Earth's interior is one of the main issues in relation to the evolution of the Earth and has been discussed by many investigators over several decades. I outline some trials...
