Geochonrology indicates that the region experienced medium to low pressure granulite facies metamorphism during the Early Paleozoic (~515-530 Ma). Although the paragneiss sequences record no evidence of earlier metamorphism, relics of a previous metamorphic event at ~1000-950 Ma are preserved in the Søstrene Orthogneiss. Within the Larsemann Hills region, the Early Paleozoic event is characterised by peak metamorphism of ~7 kbar at ~800-850°C, with the post-peak evolution characterised by decompression, with some cooling, to 4 kbars at 750°C, then to 2-3 kbar at 600-650°C during final stages of orogenesis, with exhumation largely driven by crustal extension. The Larsemann Hills are unique for the variety of phosphorous and boron minerals, some of which are found in spectacular specimens, and others of which are not found elsewhere in the world. Three of the nine phosphate minerals found are new to science: stornesite-(yytrium), tassieite and chopinite. For this dataset release the stratigraphic units from the 2007 map have been named to conform to stratigraphic nomenclature and reserved in the Australian Stratigraphic Units Database.Fieldwork supported by Australian Antarctic Science Program Project 2350 and U.S. National Science Foundation OPP-0228842 EPSG:4283 EPSG:4326 CRS:84 EPSG:3857 EPSG:28348 EPSG:28349 EPSG:28350 EPSG:28351 EPSG:28352 EPSG:28353 EPSG:28354 EPSG:28355 EPSG:28356 EPSG:28357 EPSG:28358 EPSG:32748 EPSG:32749 EPSG:32750 EPSG:32751 EPSG:32752 EPSG:32753 EPSG:32754 EPSG:32755 EPSG:32756 EPSG:32757 EPSG:32758 EPSG:3031 EPSG:3032 EPSG:102100 75.978443 76.510868 -69.475945 -69.342401 text/html Framework_Larsemann_Hills35262 The Geology of the Larsemann Hills, Princess Elizabeth Land, Antarctica GIS dataset contains the spatial data of the basement geology of the Larsemann Hills, along with field site observations.
