285 oxygen isotope analyses of grain separates of quartz, biotite, muscovite, aegirine, actinolite, olivine and chromite were carried out by laser fluorination using BrF5. Two of the eleven samples analyzed are oxygen ...

We describe a laser fluorination technique specifically for quartz that allows both high-accuracy and high-precision determination of oxygen isotope ratios, regardless of grain size. The rapid heating, defocused beam ...
