Description

Supplementary data for the article titled "Source variations in volatile contents of Bransfield Strait back-arc and Phoenix/West Scotia mid-ocean ridge lavas, northern Antarctic Peninsula," by Anderson et al. (in press) submitted to Chemical Geology. The tables include major/trace/volatile element data and radiogenic isotope ratios for glassy submarine lavas from across the northern Antarctic Peninsula.

Steps to reproduce

Volatile element (H2O, CO2, Cl, F, and S) analyses were performed using the Cameca 6F ion probe at the Carnegie Institution for Science. Major element analyses for our glasses and olivine separates were performed on the Brown University Cameca SX-100 electron microprobe. Trace element concentrations of glasses and V contents of olivine separates were determined by 193 nm wavelength excimer Analyte G2 laser ablation system coupled to a Thermo Scientific X-Series II quadrupole ICP-MS at Brown University. The new isotope data reported here were collected on hand-picked glass chips that were leached with cold 2.5N HCl for 30 minutes, dissolved in a mixture of HF(3):HNO3(1), and then processed through ion exchange chromatography. Sr, Nd, Hf, and Pb isotopic compositions were measured on a Thermo Scientific Neptune Plus MC-ICP-MS at the Mass Spectrometer Analytical Facility, Brown University. Major and trace element contents for one basaltic sample from the Seal Nunataks, R3723.7, were measured on whole rock powder at the Peter Hooper GeoAnalytical Lab at Washington State University (see lab for details on long term precision and standards).
