Archaean crust in the Rayner Complex of east Antarctica: Oygarden Group of islands, Kemp Land

Abstract: Archaean zircon grains from the Oygarden Group of islands in Kemp Land, east Antarctica, record evidence for multiple episodes of recrystallisation, dissolution and growth from the Early to Middle Archaean to the Neoproterozoic. Zircon grains in layered felsic orthogneiss have an age of ∼3650 Ma, a minimum protolith age for this rock. These zircon grains were subsequently affected by a ∼3470 Ma Pb-loss event. Homogeneous felsic orthogneiss that cuts S1, but contains an intense S2 foliation, has disturbed ∼2780… Show more

“…In addition, the age peaks at 3654,3524,3129,3070,3018,2873,2782,2684,2581, and 2491 Ma have not previously been reported in the Rayner Complex of western Enderby Land. In the Rayner Complex, similar ages can be found in limited locations such as the Øygarden Group (~3650 and~2750 Ma, UPb zircon: Kelly, 2001;Kelly et al, 2004), Edward VIII Gulf (~3100 and~2500 Ma, Rb-Sr whole rock isochron: Sheraton and Black, 1983), Fold Island (3080 ± 170 Ma, U-Pb zircon: Clarke, 1987), and Stillwell Hills (2692 ± 48 Ma, Rb-Sr whole rock isochron: Clarke, 1987) in Kemp Land. The Condon Hills area is therefore unusual in that Archean detritus remains.…”

“…6). The Eoarchean signatures are only reported from Øygarden Group in Kemp Land (~3650 Ma, U-Pb zircon: Kelly, 2001;Kelly et al, 2004;Halpin et al, 2005), and the zircon inheritance of 3850 Ma is the first report of middle Eoarchean signature in the Rayner Complex. In addition, the age peaks at 3654,3524,3129,3070,3018,2873,2782,2684,2581, and 2491 Ma have not previously been reported in the Rayner Complex of western Enderby Land.…”
