Summary

This report summarizes the cosmogenic beryllium-10 (10Be) geochronologic results from boulders deposited on moraines in the Stura Valley of the Maritime Alps, the southwestern most extent of the European Alpine mountain chain, northwestern Italy. Within this report are detailed the methodologies used to collect samples of whole rock, determine the concentrations of cosmogenic 10Be in purified quartz isolated from those samples, and use those nuclide concentrations to calculate surface exposure ages. This report should be used as supplementary material for any publication(s) that uses the nuclide concentrations and/or ages reported herein. This version supersedes all previous age estimates and reports.

Purpose

This report is for eleven samples of boulders on moraines deposited in the Stura Valley, Maritime Alps, northwestern Italy. Samples were collected 8-12 October, 2006 by Andrew Cyr (USGS, then at Purdue University, West Lafayette, IN USA), Adriano Ribolini (Department of Earth Sciences, University of Pisa, Italy), Matteo Spagnolo (Department of Geography & Environment, University of Aberdeen, UK, then at Department of Earth Science, University of Pisa, Italy), and Palo Federici (Department of Earth Sciences, University of Pisa, Italy, now retired). Sample preparation and measurement of 10Be ratios by accelerator mass spectrometry (AMS) were completed at the Purdue Rare Isotope Measurement (PRIME) Laboratory in West Lafayette, IN USA, following standard methods.
