These data suggest that existing models do not adequately describe thermalization and capture of neutrons for hydrous rock samples.

Calculated Cl production rates integrated over the last ∼15,500 cal yr between latitudes of 46.5° and 51°N.

To control electron multiplier gain in the Th measurements the MOSS (Be Inhouse) standard is used and for gain calibration for U measurements we take the NIST U 050 standard.

U /Th-samples from the Tschirgant rockslide U /Th-samples from the Pfitsch rockslide 36Cl-surface exposure ages will be determined from samples taken from sliding planes at the scarp area and/or from huge rockslide boulders at the accumulation area.

U/Th-age-dating of cemented portions of rockslides by the U-Th method thus represents a new, hitherto unexploited source for proxy age determination of catastrophic mass failures.
