From: H, C, and N isotopic compositions of Hayabusa category 3 organic samples
Scanning electron images of Hayabusa category 3 samples: (a) QD04-0047-02, (b) RA-QD02-0120, and (c) RB-QD04-0001. Regions outlined in (a) are areas of H isotopic measurements (RoI# 1, RoI# 2a and 2b in Table 2). Regions outlined in (b) are shown in Figure 3 (RoI#1) and Figure 4 (RoI#2), respectively. Regions outlined in (c ) are shown in Figure 5 (RoI#1) and Figure 6 (RoI#2), respectively.
