The trace element signature of Earth's continental crust resembles that of arc lavas, but the
continents may have formed during ancient igneous pulses that are hard to reconcile with …

Abstract The Tasmanides of eastern Australia record the break-up of Rodinia, followed by
the growth of orogenic belts along the eastern margin of Gondwana. Spatially, the …

In the late Silurian, the Lachlan Orogen of southeastern Australia had a varied
paleogeography with deep-marine, shallow-marine, subaerial environments and …

Abstract The classical S–I–A-type granites from the Lachlan Orogen, SE Australia, formed as
a tectonic end-member of the accretionary orogenic spectrum, the Paleozoic Tasmanides …

The well-known southwest-to-northeast younging of stratigraphy over a present-day cross
strike distance of> 1500 km in the southern Tasmanides of eastern Australia has been used …

The Lachlan Orogen, like many other orogenic belts, has undergone paradigm shifts from
geosynclinal to plate-tectonic theory of evolution over the past 40 years. Initial plate-tectonic …

Ordovician rocks of the Lachlan Orogen consist of two major associations, mafic to
intermediate volcanic and volcaniclastic rocks (Macquarie Arc), which aerially comprise …

The Macquarie Arc is a long-lived volcanic arc terrane which began in the latest Cambrian
and continued until the early Silurian. Early Silurian high-K suites associated with Cu–Au …

The Benambran Orogeny reflects the accretion of the intra-oceanic Macquarie Arc to the
Gondwana Plate. The ultimate cause was the northwards strike-slip transport of the …

Some published tectonic reconstructions of the eastern Lachlan Orogen in New South
Wales have shown Ordovician volcanic and volcaniclastic rocks of the Macquarie Arc …
