Structural and metamorphic evolution of the Arthur Lineament, northwestern Tasmania, Australia

TL;DRAbstract

The aim ofthis project is to investigate the origin and deformational history ofthe Arthur Lineament, using amulti-disciplinary approach. The field-based research concentrated on the structural deformation ofthe study area. Laboratory-based research included microstructural investigations, whole-rock geochemistry to investigate the mafic igneous rocks in the study area, and metamorphic petrology and geochronology to characterise the timing and nature ofthe metamorphic events that affected the lineament and surrounding region. TheArthur Lineament is a Cambrian age, high strain metamorphic belt located innorthwest Tasmania, Australia. It is east-dipping, NE-trending, 5to 10 km wide and approximately 110 km long. The lineament consists ofphyllitic to schistose lithologies that have been subject to medium- to high strain, and variably metamorphosed to blueschist, or greenschist grade. The high strain belt comprises several different units. The major lithological unit in the southern Arthur
