Abstract:
Samples collected in 2018 by Paul Asimow, Joseph Biasi, and Forrest Horton on Paallavvik (Padloping Island), Aggijat (Durban Island), and the Cumberland Peninsula on the mainland of Baffin Island. Overall dataset for these samples includes electron microprobe analyses of pillow rim glasses, melt inclusions, and phenocrysts; whole-glassy-rim analyses by XRF (major oxides) and ICP-MS (trace elements); Fe-Xanes analyses of olivine-hosted melt inclusions; SIMS analyses of volatiles in olivine-hosted melt inclusions; and FTIR analyses of glasses.
