Introduction

The Pine Creek Orogen forms the northern margin of the North Australian Craton (Plumb, 1979). Broadly, it comprises sequences of carbonaceous, clastic, and volcanogenic sediments deposited upon rifted Archaean crystalline basement, which were subsequently deformed, metamorphosed, and intruded by syn- to post-orogenic granitoids and mafic bodies. The Pine Creek Orogen can be divided into three distinct domains, reflecting different deformational, metamorphic, and stratigraphic attributes (Worden et al., in review). These are, from west to east, the Litchfield Domain, the Central Domain, and the Nimbuwah Domain.
