This paper describes the fluids circulating in the extensive thrust-related quartz-bearing vein systems developed within the low-grade turbidite-dominated Early Paleozoic Robertson Bay Terrane of north Victoria Land, Antarctica. It provides a well-preserved example of fossil accretionary complex, developed during the Paleozoic subdution-related accretionary process at the paleo-Pacifica margin of Gondwana. Fluid inclusions are analysed in quartz crystals hosted within distinct generations of veins, which are interpreted to record the incremental deformation history during shortening and accretionary complex formation. Our data provides clues to the tectono-thermal history associated with orogenic complex formation, also providing inferences on the fluid storage and recycling through time.

Abstract

This paper describes the fluids circulating in the extensive thrust-related quartz-bearing vein systems developed within the low-grade turbidite-dominated Early Paleozoic Robertson Bay Terrane of north Victoria Land, Antarctica. It provides a well-preserved example of fossil accretionary complex, developed during the Paleozoic subdution-related accretionary process at the paleo-Pacifica margin of Gondwana. Fluid inclusions are analysed in quartz crystals hosted within distinct generations of veins, which are interpreted to record the incremental deformation history during shortening and accretionary complex formation. Our data provides clues to the tectono-thermal history associated with orogenic complex formation, also providing inferences on the fluid storage and recycling through time.
