erraneChron is GEMOC’s unique methodology for studying crustal evolution and evaluating the metallogenic potential of terranes. It is based on the integrated in situ analysis of zircons for U-Pb age, Hf-isotopic composition and trace-element composition using GEMOC’s laser-ablation-microprobe (LAM) ICPMS, LAM-Multi-Collector (MC) ICPMS and electron microprobe (EMP). The method can be applied t...

The Euganean Hills (NE Italy) magmatic district represents the final volcanic activity of Veneto Volcanic Province. Alkaline to subalkaline suite dominated by intermediate felsic rocks characterises latest Hills. Magmatic (intrusive and volcanic) enclaves are common in trachytes. We used ability clinopyroxene record variations P, T, fO2 reconstruct geological history trachytic host. Despite sim...

High concentrations of acid were found to arise from the interaction between molten rock and seawater at the shoreline of Kilauea Volcano, Hawaii. A series of field samplings and experiments show that the acid was derived from two sources: the release of magmatic volatiles and water–rock reactions. Although the bulk of the magmatic volatiles (CO2, H2O, and SO2) are vented at Puu Oo cinder cone ...

[1] We report some of the first noble gas data for in situ lower oceanic crust and shallow mantle. From a suite of gabbros and peridotites recovered from the Atlantis Bank oceanic core complex on the Southwest Indian Ridge, we measured He, Ne, Ar, Kr and Xe concentrations as well as He/He and Ar/Ar ratios, there by documenting the noble gas content and signature of oceanic lithosphere. Except f...

Introduction: High chlorine abundances have been reported on the Martian surface, suggesting that Cl is widespread on Mars. GRS elemental mapping has shown that Cl is not composition-ally uniform across the surface of Mars and has a range from 0.2-1 wt% [1]. The MER rovers have confirmed the high Cl concentrations with soil analysis up to 1 wt% Cl [2]. The SNC meteorites also contain numerous a...

Compared to the Earth, its Moon is strongly depleted in volatiles, and its interior is generally treated as anhydrous. The internal volatile content of the Moon remains a critical control on its petrogenesis, and can be re-assessed in light of current interest in the Moon. One tool in this assessment is chemical (and isotopic) analysis of minerals that could contain volatile elements. One volat...

Antimony (Sb) is identified as a critical metal in many countries. The source of hydrothermal Sb-bearing deposits currently debated two opposing models (magmatic fluids or country rocks). Some systems host abundant cadmium (Cd). Due to the close association Cd and Sb distinct isotopic signatures between magmatic sedimentary rocks, isotopes have potential trace origin deposits. Here, we conducte...
