The chemical and isotopic composition of fumarolic gases emitted from Nisyros Volcano, Greece, and of a single gas sample from Vesuvio, Italy, was investigated in order to determine the origin of methane (CH4) within two ...
High precision in situ oxygen isotope analyses of quartz using an ArF laser are described. The high precision is documented by comparing in situ ArF laser data with CO2 laser and conventional analyses of silica and quartz. ...
