RB 2004/00025 Beryl in South Australia
Gem-quality varieties of beryl occur rarely in South Australia and exist in insufficient quantities to be of current economic interest. Non-gem grade beryl, by contrast, is a widespread accessory mineral in many pegmatites of South Australia, but, at...-

RB 2013/00016 A user's guide to migmatites.
Migmatites are complex, high-grade crystalline rocks that have formed by partial melting. They have been recognised within the crustal rock record across most of geological time, are seen to be developed in various tectonic settings, and can affect a...-

RB 2012/00019 Geochemistry of pre-1570 Ma mafic magmatism within southern Australia: implications for possible tectonic settings and timing of major mineralisation events in South Australia.
Geochemical and isotopic data from mantle-derived mafic rocks provide important constraints on our understanding of the composition and evolution of the lithosphere through time. Since the lithosphere is sensitive to tectonic processes such as...-
