Abstract The solubility of N 2 in basaltic (MORB) and haplogranitic melts was studied at oxidizing conditions (oxygen fugacity about two log units above the Ni–NiO buffer). Under these conditions, is expected to be only significant nitrogen species present melt. Experiments were carried out from 0.1 GPa 1000–1450 ˚C using either an externally heated TZM pressure vessel, internally gas vessel or...

Intraplate volcanism initiated shortly after the cessation of Cenozoic seafloor spreading in the South China Sea (SCS) region, but the full extent of its influence on the Indochina block has not been well constrained. Here we present major and trace element data and Sr-Nd-Pb-Hf isotope ratios of late Cenozoic basaltic lavas from the Khorat plateau and some volcanic centers in the Paleozoic Sukh...

Mid-ocean ridge basalts (MORBs), produced at mid-ocean where the continents and subduction zones are distant, product of partial melting upper mantle their chemical composition can provide information about itself. The geochemical characteristics MORBs enable us to be more informed geological processes below ridge, assist in understanding heterogeneity geodynamic processes. In this paper, new d...

The behavior of chalcophile metals in volcanic environments is important for a variety of economic and environmental applications, and for understanding large-scale processes such as crustal recycling into the mantle. In order to better define the behavior of chalcophile metals in ocean island volcanoes, we measured the concentrations of Re, Cd, Bi, Cu, Pb, Zn, Pt, S, and a suite of major eleme...

Trace-element and Nd-Sr-Pb isotopic data for mafic lavas from the Mascarene island of Mauritius reveal that the shield-stage Older Series (with 143Nd/144Nd = 0.512827 to 0.512853, 87Sr/86Sr = 0.70412 to 0.70433, and 206Pb/204Pb = 18.771 to 19.024) is geochemically very similar to the shield-building lavas of the younger island of Réunion. The post-shield Intermediate and Younger Series lavas of...

The metamorphosed mafic-ultramafic sequences of the Eastern Andean Metamorphic Complex outcropping in Patagonian Andes are critical to disclose late Paleozoic tectonic evolution southwestern margin Gondwana. In study area, bodies thrusted onto polydeformed metasedimentary rocks and intruded by mid-Carboniferous composite Leones Pluton. metabasalts (mostly tremolite-chlorite schists amphibolites...
