Modal composition and detrital clinopyroxene geochemistry of lithic sandstones from the New England fold belt (East Australia); a Paleozoic forearc terrane

The fold belt is divided by the Peel Fault into two time-equivalent zones, inferred to represent a western magmatic arc-frontal arc succession and an eastern subduction complex assemblage. The dominantly volcanogenic provenance of sandstone from east of the fault and the low Ti content of most detrital clinopyroxene grains indicate that the volcanic chain that lay to the west of the Peel Fault was the most likely source for the major portion of the clastic debris in the eastern rocks.--Modified journal abstract.
