| Summary: | This dataset includes U-Pb, Lu-Hf, and O analyses of zircons from two igneous rocks: sample EHD0701A (79°57'47.43"S, 82°56'58.32"W) and sample EHD0305A (80°03'00.87"S, 82°59'07.91"W). EHD0701A is a foliated porphyritic hornblende micro-diorite, while EHD0305A is a basaltic andesite. Additionally, it contains Lu-Hf and O analyses of detrital zircon grains from ten meta-sedimentary samples: 13EG-01, 13EG-02, EHD2302A, EHD0801A, 13EG-05, EHD1705A, EA6, EAM1001B, 13EG-15, and 13EG-10. The coordinates for these samples and U-Pb data are published in Castillo et al. (2017). Zircon separation and analysis were conducted at the Australian National University in Canberra, Australia.
