  31. <meta content="Surface-wave tomography for the Australian region, using data mostly from portable seismic recorders,
  32. reveals a very strong contrast in seismic shear-wave speed beneath central and western Australia
  33. and the east of the continent. Shear-wave speeds faster than the continental average extend to at
  34. least 200 km depth in the cratonic zone to the west of 140 degrees E. Along an approximately north-south line
  35. there is then an eastward step to thinner lithosphere (~150 km thick) but still with fast shear-wave
  36. speeds. A further more irregular transition to the east marks the transition to lowered shear-wave
  37. speeds. The eastern transition at 75 km depth is in close agreement with the original Tasman Line,
  38. whereas the two more westerly transitions do not bear a simple relation to the more recent group of
  39. Tasman Lines defined from crustal information (outcrop and inferred geophysical trends). The westward
  40. transition to the thickest coherent lithosphere (near 140 degrees E) may well mark the edge of the ancient
  41. core of the continent, but the current mantle structures must bear the scars of the breakups and reassembly
  42. that have created the current Australian continent." name="eprints.abstract" />

  229. reveals a very strong contrast in seismic shear-wave speed beneath central and western Australia&#13;
  230. and the east of the continent. Shear-wave speeds faster than the continental average extend to at&#13;
  231. least 200 km depth in the cratonic zone to the west of 140 degrees E. Along an approximately north-south line&#13;
  232. there is then an eastward step to thinner lithosphere (~150 km thick) but still with fast shear-wave&#13;
  233. speeds. A further more irregular transition to the east marks the transition to lowered shear-wave&#13;
  234. speeds. The eastern transition at 75 km depth is in close agreement with the original Tasman Line,&#13;
  235. whereas the two more westerly transitions do not bear a simple relation to the more recent group of&#13;
  236. Tasman Lines defined from crustal information (outcrop and inferred geophysical trends). The westward&#13;
  237. transition to the thickest coherent lithosphere (near 140 degrees E) may well mark the edge of the ancient&#13;
  238. core of the continent, but the current mantle structures must bear the scars of the breakups and reassembly&#13;
  239. that have created the current Australian continent.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">craton, lithosphere, seismology, Tasman Line.</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/260100.html">260000 Earth Sciences &gt; 260100 Geology</a></td></tr><tr><th valign="top" class="ep_row">Collections:</th><td valign="top" class="ep_row">UNSPECIFIED</td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1587</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Mrs Katrina Keep</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">13 Aug 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">30 Jan 2008 15:32</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1587;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=1587">item control page</a></p>
