Isotopic dating and petrography of rock samples collected from central Alexander Island, 2005-2006
GB/NERC/BAS/PDC/00598
Abstract:
Datasets related to istopic dating of mylonites and detrital grains from central Alexander Island. Argon-argon dating of mylonites and detrital grains, as well as uranium-lead dating of detrital zircons has been completed. Rock samples were collected from the northern LeMay Range, southern Douglas Range and the Lully Foothills.
