40Ar-39Ar ages of ice-rafted sand-sized hornblende and mica deposited in Iceberg Alley (NERC Grant NE/T006609/1)
40Ar/39Ar ages of 37 mica and 21 hornblende from the sand-sized fraction of an iceberg-rafted debris-rich layer deposited in the Scotia Sea at IODP Site U1538 ~1.2 million years ago during the early Pleistocene.

Hornblende, mica and standards were irradiated at the Cd-lined in-core facility at the Oregon State reactor. 40Ar/39Ar ages were obtained using single-step CO2 laser fusion at the Lamont Doherty Earth Observatory argon geochronology lab (Argon Geochronology for the Earth Sciences) to release argon, followed by cleanup with Zr-Ar getters heated at 2-amps. Extracted and cleaned gases were measured on a VG5400 noble gas mass spectrometer in peak hopping mode on an analogue multiplier, using the program Massspec. Nuclear interference corrections used values for OSU from Renne et al. (1998), and data were also corrected for background and mass discrimination using measured blanks and air pipettes. J values used to calculate ages were based on co-irradiated Fish Canyon sanidine standard (28.201 ± 0.046 Ma; Kuiper et al. (2008), with decay constants from Min et al. (2000)).
