Fig. 8.From: Single grain noble gas analysis of Antarctic micrometeorites by stepwise heating method with a newly constructed miniature furnace3He/4He versus 20Ne/22Ne for nine snow-AMMs. Data for ice-AMMs (Osawa and Nagao, 2002; Osawa et al., 2003a) are presented for comparison. Isotopic ratios for SW are 3He/4He = 0.000464 and 20Ne/22Ne = 13.78 (Heber et al., 2009). Errors are 1σ.Back to article page
