Vanadium in peridotites as a proxy for paleo-�O 2 during partial melting: Prospects, limitations, and implications
The compatibility of vanadium (V) during mantle melting is a function of oxygen fugacity (fO2): At high fO2's, V becomes more incompatible. The prospects and limitations of using the V content of peridotites as a proxy for paleo- fO2 at the time of melt extraction were investigated here by assessing the uncertainties in V measurements and the sensitivity of V as a function of degree of melt extracted and fO2. V-MgO and V-Al2O3 systematics were found to be sensitive to fO2 variations, but...[Show more]
