Summary
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.
Keywords:
Alexander Island, Ar-Ar dating, U-Pb dating
