“…[], Poreda and Cerling [], and Fenton et al . [], and assuming 1 mm kyr −1 erosion, yields an uncertainty‐weighted mean 3 He date of 17.5 ± 1.8 ka (1σ) and a 21 Ne date of 19.7 ± 2.5 ka (1σ), which are indistinguishable from the 36 Cl date of 17.1 ± 1.4 ka (1σ) for an accretionary lava ball on the same flow unit (Table , Figure ). Hence, three independent methods for dating the duration of exposure since eruption yield concordant results for the Armstrong Canyon flow.…”

The Big Pine volcanic field is one of several Quaternary volcanic fields that poses a potential volcanic hazard along the tectonically active Owens Valley of east-central California, and whose lavas are interbedded with deposits from Pleistocene glaciations in the Sierra Nevada Range. Previous geochronology indicates an 1.2 Ma history of volcanism, but the eruption ages and distribution of volcanic products associated with the most-recent eruptions have been poorly resolved. To delimit the timing and products of the youngest volcanism, we combine field mapping and cosmogenic 36 Cl dating of basaltic lava flows in the area where lavas with youthful morphology and well-preserved flow structures are concentrated. Field mapping and petrology reveal approximately 15 vents and 6 principal flow units with variable geochemical composition and mineralogy. Cosmogenic 36 Cl exposure ages for lava flow units from the top, middle, and bottom of the volcanic stratigraphy indicate eruptions at 17, 27, and 40 ka, revealing several different and previously unrecognized episodes of late Pleistocene volcanism. Olivine to plagioclase-pyroxene phyric basalt erupted from several vents during the most recent episode of volcanism at 17 ka, and produced a lava flow field covering 35 km 2 . The late Pleistocene 36 Cl exposure ages indicate that moraine and pluvial shoreline deposits that overlie or modify the youngest Big Pine lavas reflect Tioga stage glaciation in the Sierra Nevada and the shore of paleo-Owens Lake during the last glacial cycle.

“…However, despite the recent report of well-constrained calibration sites, a non negligible variability of the worldwide production rates remains, after scaling to sea level and high latitude (Blard et al, 2013;Fenton et al, 2013;Goehring et al, 2010). Although both geological scatter and scaling model inaccuracies may explain a part of this dispersion, analytical variability may also be involved.…”

“…Fifth, helium isotopes can be measured with commercial noble gas mass spectrometers, such as VG-5400, MAP or Helix-SFT instruments, and do not require complicated chemical pre-treatments. Sixth, the knowledge of its production rate has recently improved, thanks to the discovery of well-constrained calibration sites (Blard et al, 2013;Fenton et al, 2013;Goehring et al, 2010).…”

Calculation of surface exposure ages, using in situ cosmogenic nuclides, requires accurate knowledge of local production rates. Here, we report the first attempt to calibrate cosmogenic 3 He production in the south-west Pacific region. We present a new radiocarbon chronology that precisely dates the emplacement of the Murimotu Formation, a large debris avalanche deposit in central North Island, New Zealand (ca. 830 m asl; 39˚S), which occurred 10.4-10.6 cal ka BP. Measurements of cosmogenic 3 He in pyroxene separated from large andesitic blocks exposed during this event yield a sea-level high-latitude production rate of 120 AE 12 atoms g À1 a À1 ('Lm' scaling). This is consistent with a recent global compilation, comprised predominantly of calibration sites located in the Northern Hemisphere. Thus, we conclude that the globally compiled cosmogenic 3 He production rate is valid in the south-west Pacific. Using independent, proximal calibrations of cosmogenic isotopes
