  31. <meta content="Pumiceous peperite is associated with a rhyolitic sill that intruded wet, unconsolidated, submarine stratified
  32. pumice breccia in the Cambrian Mount Read Volcanics, Australia. Other examples of pumiceous peperite described in
  33. this paper occur at the pumiceous base of a rhyolitic lava and the margins of a rhyolitic cryptodome complex in the
  34. Miocene Green Tuff Belt, Japan. Intervals of pumiceous peperite are thin (less than 15 m), laterally discontinuous, massive, poorly sorted and the clast-to-matrix ratio varies significantly over short distances. They are composed of feldsparphyric tube pumice clasts and domains of clastic sediment that include stratified pumice breccia, pumiceous siltstone and bioturbated mudstone. The sediment domains may be massive or may display relic depositional structures.
  35. Sediment adjacent to pumice clasts is silicified, possibly reflecting induration on contact with hot pumice. Pumiceous
  36. peperite has gradational contacts with in situ and clast-rotated pumiceous hyaloclastite and coherent pumiceous
  37. rhyolite. Gradational relationships between pumiceous peperite and coherent pumiceous rhyolite, pumice clasts with
  38. chilled margins and curviplanar surfaces, and abundant jigsaw-fit texture imply that quench fragmentation and
  39. autobrecciation were the dominant mechanisms of clast formation. The formation of pumiceous peperite is favoured
  40. by a combination of low confining pressure and delayed quenching allowing vesiculation. Pumiceous peperite may
  41. easily be misinterpreted or overlooked as it resembles other pumice-rich facies that are common in submarine volcanic successions. The correct identification of pumiceous peperite can provide evidence to constrain the timing of intrusive episodes in volcanic successions." name="eprints.abstract" />

  316. pumice breccia in the Cambrian Mount Read Volcanics, Australia. Other examples of pumiceous peperite described in&#13;
  317. this paper occur at the pumiceous base of a rhyolitic lava and the margins of a rhyolitic cryptodome complex in the&#13;
  318. Miocene Green Tuff Belt, Japan. Intervals of pumiceous peperite are thin (less than 15 m), laterally discontinuous, massive, poorly sorted and the clast-to-matrix ratio varies significantly over short distances. They are composed of feldsparphyric tube pumice clasts and domains of clastic sediment that include stratified pumice breccia, pumiceous siltstone and bioturbated mudstone. The sediment domains may be massive or may display relic depositional structures.&#13;
  319. Sediment adjacent to pumice clasts is silicified, possibly reflecting induration on contact with hot pumice. Pumiceous&#13;
  320. peperite has gradational contacts with in situ and clast-rotated pumiceous hyaloclastite and coherent pumiceous&#13;
  321. rhyolite. Gradational relationships between pumiceous peperite and coherent pumiceous rhyolite, pumice clasts with&#13;
  322. chilled margins and curviplanar surfaces, and abundant jigsaw-fit texture imply that quench fragmentation and&#13;
  323. autobrecciation were the dominant mechanisms of clast formation. The formation of pumiceous peperite is favoured&#13;
  324. by a combination of low confining pressure and delayed quenching allowing vesiculation. Pumiceous peperite may&#13;
  325. easily be misinterpreted or overlooked as it resembles other pumice-rich facies that are common in submarine volcanic successions. The correct identification of pumiceous peperite can provide evidence to constrain the timing of intrusive episodes in volcanic successions.</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">Additional Information:</th><td valign="top" class="ep_row">The definitive version is available online at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">pumiceous peperite; pumice breccia; rhyolite; submarine volcanic succession; Mount Read Volcanics; Green Tuff Belt</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/260103.html">260000 Earth Sciences &gt; 260100 Geology &gt; 260103 Vulcanology</a><br /><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">1820</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 Sep 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">30 Jan 2008 15:17</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=1820;">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=1820">item control page</a></p>
