Abstract

[Abstract] The post-congress field trip will depart Cairns and travel through the Paleozoic Hodgkinson Province to Chillagoe, which is near the province-bounding Tasman Line, a major north–south structure that extends through eastern Australia, and separates largely Paleozoic rocks from the Paleoproterozoic to Mesoproterozoic rocks to the west. The excursion then visits sites of some of Australia's youngest volcanism, part of an intraplate alkali basalt assemblage, before examining rocks of the Paleoproterozoic to Mesoproterozoic Etheridge Province. The excursion will then cross back over the Tasman Line, visiting Paleozoic sediments and early Paleozoic metamorphic rocks and granitoids of the Greenvale, Broken River and Charters Towers Provinces before ending in Townsville. Much of the excursion route follows deep seismic traverse lines shot in 2007, interpretation of which provides a perspective of deep crustal structure in relation to surface rock assemblages.
