Fig. 3: Detrital garnet EPMA compositional data for the beach sand samples MYB, PCB, PMB and PVB.
From: An Ediacaran orogeny in subglacial East Antarctica is uncovered by detrital garnet geochronology
a, b Detrital garnets are classified according to the interpreted composition and setting of their host rocks, respectively, using the scheme of Schönig et al.36. c Detrital garnets plotted on a ternary diagram by metamorphic facies grade, using the same classifier36 (cfr.20). d Combined triple ternary plot82, which displays the detrital garnets based on their end-member compositions. The detrital garnets are all grouped or colour-coded according to their interpreted source in South Australia (Palaeo-Mesoproterozoic Barossa Complex as green circles, Ediacaran as blue diamonds, Delamerian as red squares). The EPMA compositional data is provided in Supplementary Data 4. AM amphibolite facies grade, BS/GS blueschist/greenschist facies grade, EC/UHP eclogite/ultrahigh-pressure facies grade, GR granulite facies grade, Alm almandine, Gro grossular, Pyr pyrope, Spe spessartine.
