U–Th–Pb detrital zircon geochronology from the southern Prince Charles Mountains, East Antarctica—Defining the Archaean to Neoproterozoic Ruker Province
Laser ablation inductively coupled mass spectrometry (LA-ICPMS) dating of detrital zircon has been employed to tighten geochronological constraints from the southern Prince Charles Mountains, East Antarctica.

Laser ablation inductively coupled mass spectrometry (LA-ICPMS) dating of detrital zircon has been employed to tighten geochronological constraints from the southern Prince Charles Mountains, East Antarctica. The grains of detrital zircon are from extensive metasedimentary units that define different stratigraphic levels. Provenance information from this study has identified three lithostratigraphic units that range in age from Archaean to Neoproterozoic times. The newly defined Tingey Complex contains the oldest known strata, and consists of an Archaean felsic basement overlain by three stratigraphic layers, distinguished by ca. 3200 Ma, ca. 2800 Ma and ca. 2500 Ma detrital zircon grains. The Lambert Complex consists of a metasedimentary package, characterised by ca. 2100 Ma, ca. 1900–1800 Ma and ca. 2600 Ma detrital zircon grains that possibly overlies late Palaeoproterozoic orthogneiss.
