Table 1 Guideline for sampling for 10Be and 26Al

From: Post-depositional impacts on ‘Findlinge’ (erratic boulders) and their implications for surface-exposure dating

Step (after the selection of sample)
 Determine the geographical position and altitude
 Take photographs of the boulder
 Measure the dimension of the boulder
 Measure the strike and dip of the top surface
 Measure topographical shielding
 Measure local shielding
 Describe vegetation
 Describe the potential sample with its surrounding (e.g. lithology, weathering, and differential movements)
 Take photographs of the potential surface
 Take the sample (up to the required weight)
 Take the pictures of the sample and boulder after sampling
