  28. <meta content="Miocene submarine basanite pillows, lava lobes, megapillows and sheet lavas in the Stanley Peninsula,
  29. northwestern Tasmania, Australia, are well-preserved in three dimensions. The pillows have ropy wrinkles, transverse
  30. wrinkles, symmetrical wrinkles, contraction cracks and three types of spreading cracks on their surfaces, and
  31. concentric and radial joints in the interior. The lava lobes have ropy wrinkles and contraction cracks on their surfaces.
  32. The megapillows are cylindrical with a smoothly curved upper surface and steep sides, and are characterized by
  33. distinct radial columnar joints in the interior. They are connected to pillows that propagate radially from its basal
  34. margin. The sheet lavas are tabular and have vertical columnar joints in the interior. The largest sheet lava shows a
  35. remarkable gradation from a lower 5-m-thick pillow facies to an upper massive facies. The pillows, lava lobes,
  36. megapillows and sheet lavas are inferred to have been emplaced completely below sea level but in a shallow marine
  37. environment. Their morphological features suggest that the pillows grew by episodic rupture of a near-solid crust and
  38. emergence of hot lava, whereas the lava lobes propagated by continuous stretching of the outer skin at the flow front.
  39. The megapillows and sheet lavas were master feeder channels by which molten lava was conveyed to the advancing
  40. pillows. The sheet lavas propagated by repeated processes of pillow formation and overriding by an upper massive
  41. part. Alternating pillow and massive facies commonly found in ocean-floor drill cores and exposed in cross-section in
  42. many subaqueous volcanic successions may have formed by propagation of pillows from the basal margins of
  43. advancing sheet lavas." name="eprints.abstract" />

  291. northwestern Tasmania, Australia, are well-preserved in three dimensions. The pillows have ropy wrinkles, transverse&#13;
  292. wrinkles, symmetrical wrinkles, contraction cracks and three types of spreading cracks on their surfaces, and&#13;
  293. concentric and radial joints in the interior. The lava lobes have ropy wrinkles and contraction cracks on their surfaces.&#13;
  294. The megapillows are cylindrical with a smoothly curved upper surface and steep sides, and are characterized by&#13;
  295. distinct radial columnar joints in the interior. They are connected to pillows that propagate radially from its basal&#13;
  296. margin. The sheet lavas are tabular and have vertical columnar joints in the interior. The largest sheet lava shows a&#13;
  297. remarkable gradation from a lower 5-m-thick pillow facies to an upper massive facies. The pillows, lava lobes,&#13;
  298. megapillows and sheet lavas are inferred to have been emplaced completely below sea level but in a shallow marine&#13;
  299. environment. Their morphological features suggest that the pillows grew by episodic rupture of a near-solid crust and&#13;
  300. emergence of hot lava, whereas the lava lobes propagated by continuous stretching of the outer skin at the flow front.&#13;
  301. The megapillows and sheet lavas were master feeder channels by which molten lava was conveyed to the advancing&#13;
  302. pillows. The sheet lavas propagated by repeated processes of pillow formation and overriding by an upper massive&#13;
  303. part. Alternating pillow and massive facies commonly found in ocean-floor drill cores and exposed in cross-section in&#13;
  304. many subaqueous volcanic successions may have formed by propagation of pillows from the basal margins of&#13;
  305. advancing sheet lavas.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><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">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">lava morphology; submarine; pillow; propagation style; basanite</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">ID Code:</th><td valign="top" class="ep_row">2044</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">04 Oct 2007 16:46</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</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=2044;">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=2044">item control page</a></p>
