520 3# ‡aConsiders tectonic implication of distinctive B- and P-rich units such as tourmaline metaquartzite and variety of biotite gneisses that contain high-temperature borosilicate minerals grandidierite and prismatine within basin paragneiss sequence exposed in Larsemann Hills, and compares this suite of rocks with similar suites reported from East Gondwana, including tourmaline-rich rocks associated with Pb-Zn-Ag deposits in Broken Hill district, Australia; and prismatine-bearing rocks in Windmill Islands, Antarctica. Enrichment in boron and phosphorus is attributed to premetamorphic hydrothermal alteration, either in rifted, most likely marine basin or in mud volcanic system located inboard of continental arc active along leading edge of Indo-Antarctic craton. This margin developed before collision with Australo-Antarctic craton merged these rocks in Gondwana and sutured them into present position in Antarctica. Rocks lithologically similar to those in Larsemann Hills include prismatine-bearing gneisses and apatitic iron formation in Willyama Supergroup, Broken Hill.
