Discussion: A recent paper (Ex on and Johnson, 1986) in this journal concluded that activity attributed in the past to the Cook submarine volcano, in the forearc region of the... -
A new nannofossil zone based on the Santonian Gingin Chalk, Perth Basin,...
Studies of the Gingin Chalk have indicated that it is Santonian in age; these studies did not deal with calcareous nannofossils. Santonian biostratigraphy in terms of... -

A Proterozoic rift zone at Mount Isa, Queensland, and implications for mineralisation
The Leichhardt River Fault Trough (LRFT) near Mount Isa is thought to be an ensialic or continental margin rift structure formed about 1800-1650 m.y. ago. Extension in old... -
Metasomatic zoning in sapphirine-bearing granulites from Antarctica
Highly magnesian (mg about 98) granulites, containing sapphirine, enstatite, spinel, phlogopite, and cordierite, occur as xenoliths in Precambrian orthopyroxene-bearing granitic... -

Petrology and geochemistry of Proterozoic dolerites from the Mount Isa Inlier
The Precambrian Mount Isa Inlier in northwest Queensland is extensively cut by numerous dolerite intrusions. At least two distinct episodes of dolerite intrusion have been... -
Whole-rock regional oxygen-isotope depletion patterns as a guide to...
The recognition of regional oxygen-isotope depletion patterns in high-level igneous rocks provides a means to discriminate areas potentially prospective for low sulphidation... -
