Abstract
[Extract] Siluro-Devonian tracts of the northern Tasmanides largely consist of accretionary complex rocks which formed outboard of forearc and arc elements. For the Broken River Province, the accretionary complex consists mostly of poly-deformed turbidites, extensively disrupted by melange, with minor components of MORB-type basalt and chert. However, Late Ordobician volcanics and marine strata form a distinctive terrane located on the inboard margin, the oldest part of the accretionary complex, faulted against pre-Silurian basement and subjacent to an extensive forearc assemblage.
