The Gondwana Plate margin in the Weddell Sea sector: Zircon geochronology of Upper Paleozoic (mainly Permian) strata from the Ellsworth Mountains and eastern Ellsworth Land, Antarctica

Elliot, D.H.; Fanning, Christopher; Laudon, Thomas S.

Description

Zircon geochronology has been applied to upper Paleozoic (mainly Permian) strata from the Ellsworth Mountains and from enigmatic outcrops in eastern Ellsworth Land to aid in constraining their locations in the Weddell Sea sector of the Gondwana plate margin. Detrital zircons from two Polarstar Formation (Ellsworth Mountains) sandstones yielded maximum depositional ages of ~ 270. Ma and ~ 260. Ma. Detrital zircons from Permian beds at Erehwon Nunatak and beds of uncertain age at FitzGerald...[Show more]
