New evidence of Tasmanias tectonic history from a novel seismic experiment

Rawlinson, Nicholas; Houseman, Gregory Austin; Collins, C.D.N.; Drummond, B

Description

In March 1995, 44 land-based recorders were deployed throughout Tasmania, SE Australia, to record seismic energy from an encircling array of marine normal-incidence reflection shot lines. We invert refraction and wide-angle reflection traveltimes for crustal structure, with the principal outcome being a map of the Tasmanian Moho. Key tectonic inferences from this map include: (1) the Arthur Lineament metamorphic belt in NW Tasmania overlies a major change in crustal thickness (over 5 km) and...[Show more]
