Ternary diagrams of the chemical compositions (Si –Mg–Fe on the right and S–Mg–Fe on the left) of amorphous silicates analyzed by STEM–EDS. The experiments were divided into three groups according to their relative Fe abundance; Group1 (Rad–100, Tan–100, Tan–95), Group 2 (Tan–75, Rad– 75L, DCP–75, Tan–50), and Group 3 (Tan–85, Rad–75H, Rad–50). The chemical composition of GEMS-like material (Leroux et al. 2015; Matsumoto et al. 2019) and GEMS in CP-IDPs (Bradley 1988, 1994a,b; Keller & Messenger 2011) and micrometeorites (Noguchi et al. 2015) were plotted in (a) and (b), respectively, according to their resemblance in mineral phase and texture to the experimental products. Also, the data from the numbered square in Fig. 5c (middle) of Rad-75L are plotted in a separate ternary diagram (b) (left) to show the relationship between texture and chemical composition. Each plot is a composition extracted from a STEM-EDS mapping of the condensate. Nano-inclusions were avoided. The shaded area in the Mg–Si–Fe diagram is the two-liquid region calculated from the diagram of Levin et al. (1964).
