“…Specifically, the Eyre Creek Melange is essentially a broken formation of gabbro, basaltic lavas and chert. This is interpreted as emplaced oceanic crust that could be significantly older than the presumed age of the melange, based on a possible Carboniferous conodont occurrence (Pound et al 2014).…”

The Western Province is a fragment of the c. 500 Ma SE Gondwana active continental margin. The Eastern Province is a terrane assemblage, which is partly stitched by the Median Batholith. Fragments of the batholith are preserved in the adjacent Drumduan and Brook Street terranes. Permian arc magmatism of the Brook Street Terrane involved both oceanic and continental margin settings. The Permian (c. 285-275 Ma) supra-subduction zone Dun Mountain ophiolite records subduction initiation and subsequent oceanic-arc magmatism. The Permian Patuki and Croisilles melanges represent detachment of the ophiolitic forearc and trench-seamount accretion. The Murihiku Terrane, a proximal continental margin forearc basin, received detritus from the Median Batholith (or equivalent). The south coast, Early-Late Triassic Willsher Group is another proximal forearc basin unit. The sediments of the Dun Mountain-Maitai Terrane (Maitai basin) represent a distal segment of a continental margin forearc basin. The Caples Terrane is a mainly Triassic trench accretionary complex, dominantly sourced from a continental margin arc, similar to the Median Batholith. The outboard (older) Torlesse and Waipapa terranes are composite subduction complexes. Successively more outboard terranes may restore farther north along the SE Gondwana continental margin. Subduction and terrane assembly were terminated by collision (at c. 100 Ma), followed by rifting of the Tasman Sea Basin.

“…South of the Alpine Fault, a potential correlative of the Croisilles Melange is the (thinner) Greenstone Melange, which crops out within the Caples Terrane to the east of the Livingstone Fault. Farther east, the Caples Terrane includes additional narrow melange belts, of which the best known is the Eyre Creek Melange (Pound et al 2014).…”
