Fig. 3. Active driftsand at Bedafse Bergen. The 180 cm deep profile pit (author inside pit shown for scale) was located on the western foot slope (a). The Mormoder was sampled at the crest of the ridge marked by vegetation in (a). The BET-BAY 002 profile (b) is characterized by a polycyclic soil sequence consisting of an Arenosol in driftsand deposits overlying a Podzol in coversands.Figure optionsDownload full-size imageDownload as PowerPoint slide

Fig. 5. Ternary plot of the separates high-density minerals from both field sites. Marker colors denote the different separation protocols used for selecting the studied samples; blue for heavy liquid mineral separation, and gray for a more elaborate selection based on the characteristics of micrometeorites. The gray areas enclose the compositional field commonly used for identifying micrometeorites, due to their different elemental composition as a result of the decay of radionuclide 26Al to 26Mg in un-metamorphosed materials from space. The conservative compositional field (dark gray) is from Taylor et al. (2000) and Sauvet et al. (2009), while the broader field (light gray) was used by Genge et al. (2005).Figure optionsDownload full-size imageDownload as PowerPoint slide
