Electrical conductivity in a partially molten crust from measurements on metasedimentary enclaves

The complex electrical impedance of a garnet-biotite-sillimanite residual enclave in the Neogene dacite of El Hoyazo (SE Spain) has been determined up to 978. °C at 200-300. MPa. This well studied material represents a direct sampling of the Alborán Domain ...

Distribution of platinum-group elements and Os isotopes in chromite ores from Mayari-Baracoa Ophiolitic Belt (eastern Cuba)

Anders Meibom, Reto Frei

The Mayari-Baracoa ophiolitic belt in eastern Cuba hosts abundant chromite deposits of historical economic importance. Among these deposits, the chemistry of chromite ore is very variable, ranging from high Al (Cr#=0.43-0.55) to high Cr (Cr#=0.60-0.83) com ...

The statistical upper mantle assemblage

Anders Meibom

A fundamental challenge in modern mantle geochemistry is to link geochemical data with geological and geophysical observations. Most of the early geochemical models involved a layered mantle and the concept of geochemical reservoirs. Indeed, the two layer ...

Are high He-3/He-4 ratios in oceanic basalts an indicator of deep-mantle plume components?

Anders Meibom, Reto Frei

The existence of a primordial, undegassed lower mantle reservoir characterized by high concentration of He-3 and high He-3/He-4 ratios is a cornerstone assumption in modern geochemistry. It has become standard practice to interpret high He-3/He-4 ratios in ...

A Study Of Sio2 Glass And Supercooled Liquid To 1950 K Via High-Temperature Raman-Spectroscopy

Philippe Gillet

We have measured in situ Raman spectra of SiO2 glass between room temperature through the glass transformation range to the supercooled liquid at 1950 K, using a new wire loop heating technique. These results provide valuable insights into the structural a ...
