Notes: All values are averages of the BHVO-2 and K-1919 reductions of each run. Only the K-1919 reduction was used for Site 1183 samples. Certified vanadium values are unavailable for K-1919. BHVO-2, BCR-2, and BIR-1 are USGS-certified basalt standards. K-1919 is a noncertified laboratory standard from the University of Massachusetts. * = total Fe expressed as Fe2O3. BD = below detection limit.
