(a) Fe-Si-Mg plot showing compositions of scoriaceious particles (n = 107) in the present collection compared with the matrix compositions of different groups/sub-groups of chondritic meteorites. Data for different groups/sub-groups of chondritic meteorites are from: CM chondrite data^37,38,39; CV chondrite data^{38,39,40,41,42,43}; CO chondrite data^39,40,44; CI chondrite data^{38,39,45,46,47,48,49,50}; CR chondrite data^38,39; EH chondrite data³⁹; LL chondrite data^43,44,51; L chondrite data⁵¹; H chondrite data^44,51; UOC chondrite data^52,53. (b) Triangular plot showing the compositions of glassy, hardened particles (n = 12) in comparison with the matrices of different groups/sub-groups of chondritic meteorites. Data for different groups/sub-groups of chondritic meteorites are from: CM chondrite data^37,38,39; CV chondrite data^{38,39,40,41,42,43}; CO chondrite data^39,40,44; CI chondrite data^{38,39,45,46,47,48,49,50}; CR chondrite data^38,39; EH chondrite data³⁹; LL chondrite data^43,44,51; L chondrite data⁵¹; H chondrite data^44,51; UOC chondrite data^52,53.
