Introduction
Supplementary Table S1 is one .xlsx file that includes two spreadsheets. This table
provides U-Pb and Hf isotope analyses of zircons from the Gympie terrane.
Supplementary Figure S1 is a pdf file illustrating photos and photomicrographs of
analyzed samples in this study. (a) A poorly sorted feldspathic greywacke from the
Rammutt Formation (GY1312) with sub-rounded to sub-angular quartz (Q) and feldspar
(F) clasts in a clay-rich matrix. A slaty cleavage is defined by dissolution seams (narrow
black lines) in this sample. (b) A well-bedded tuffaceous sandstone from the Rammutt
Formation (GY1317). (c) An interstratified tuff layer (GY1302) within the South Curra
Limestone. (d) A fine-grained feldspathic arenite of the Tamaree Formation (GY1307)
with sub-angular quartz (Q) and feldspar (F), as well as minor mica flakes. (e) A fine to
medium-grained poorly sorted lithic arenite of the Tamaree Formation (GY1311),
containing sub-angular quartz (Q), feldspar (F) and sedimentary/volcanic lithic (L)
1
fragments and minor mica flakes. (f) A matrix-supported conglomerate from the Keefton
Formation (GY1331) with rounded to sub-angular quartz and sedimentary lithic clasts, as
well as minor volcanic/plutonic fragments. (g-h) Two phyllite samples from the Kin Kin
beds (GY1310 and GY1334) with penetrative slaty cleavages defined by the preferred
alignment of micas and lenticular clasts.
Supplementary Figure S2 is a pdf file presenting concordia diagrams for zircon U–Pb
analyses with the sample number indicated in the figure. Ellipses with gray color were
excluded for the weighted mean age calculation of volcanic rocks (Figure S2c).
