In-situ U-Pb geochronology and Hf isotope analyses of the Rayner Complex, east Antarctica
In-situ zircon UPb and Hf isotopic analysisvia laser ablation microprobe-inductively coupled plasmamass spectrometer (LAM-ICPMS) of samples fromKemp and MacRobertson Lands, east Antarctica suggeststhat the Kemp Land terrane evolved separatelyfrom the rest of the Rayner Complex prior to the ca.940 Ma...
