  30. <meta content="The Filakopi Pumice Breccia (FPB) is a very
  31. well exposed, Pliocene volcaniclastic unit on Milos,
  32. Greece, and has a minimum bulk volume of 1 km3. It
  33. consists of three main units: (A) basal lithic breccia (4–
  34. 8 m) mainly composed of angular to subangular, andesitic
  35. and dacitic clasts up to 2.6 m in diameter; (B) very thickly
  36. bedded, poorly sorted pumice breccia (16–17 m); and (C)
  37. very thick, reversely graded, grain-supported, coarse
  38. pumice breccia (6.5–20 m), at the top. The depositional
  39. setting is well constrained as shallow marine (up to a few
  40. hundred metres) by overlying fossiliferous and bioturbated
  41. mudstone. This large volume of fine pumice clasts is
  42. interpreted to be the product of an explosive eruption
  43. from a submarine vent because: (1) pumice clasts are the
  44. dominant component; (2) the coarse pumice clasts
  45. (>64 mm) have complete quenched margins; (3) very
  46. large (>1 m) pumice clasts are common; (4) overall, the
  47. formation shows good hydraulic sorting; and (5) a
  48. significant volume of ash was deposited together with
  49. the coarsest pyroclasts.
  50. The bed forms in units A and B suggest deposition
  51. from lithic-rich and pumiceous, respectively, submarine
  52. gravity currents. In unit C, the coarse (up to 6.5 m)
  53. pumice clasts are set in matrix that grades upwards from
  54. diffusely stratified, fine (1–2 cm) pumice clasts at the
  55. base to laminated shard rich mud at the top. The coarse
  56. pumice clasts in unit C were settled from suspension and
  57. the framework was progressively infilled by fine pumice
  58. clasts from waning traction currents and then by watersettled ash. The FPB displays important features of the
  59. products of submarine explosive eruptions that result
  60. from the ambient fluid being seawater, rather than volcanic gas or air. In particular, submarine pyroclastic
  61. deposits are characterised by the presence of very coarse
  62. juvenile pumice clasts, pumice clasts with complete
  63. quenched rims, and good hydraulic sorting." name="eprints.abstract" />

  378. well exposed, Pliocene volcaniclastic unit on Milos,&#13;
  379. Greece, and has a minimum bulk volume of 1 km3. It&#13;
  380. consists of three main units: (A) basal lithic breccia (4–&#13;
  381. 8 m) mainly composed of angular to subangular, andesitic&#13;
  382. and dacitic clasts up to 2.6 m in diameter; (B) very thickly&#13;
  383. bedded, poorly sorted pumice breccia (16–17 m); and (C)&#13;
  384. very thick, reversely graded, grain-supported, coarse&#13;
  385. pumice breccia (6.5–20 m), at the top. The depositional&#13;
  386. setting is well constrained as shallow marine (up to a few&#13;
  387. hundred metres) by overlying fossiliferous and bioturbated&#13;
  388. mudstone. This large volume of fine pumice clasts is&#13;
  389. interpreted to be the product of an explosive eruption&#13;
  390. from a submarine vent because: (1) pumice clasts are the&#13;
  391. dominant component; (2) the coarse pumice clasts&#13;
  392. (&gt;64 mm) have complete quenched margins; (3) very&#13;
  393. large (&gt;1 m) pumice clasts are common; (4) overall, the&#13;
  394. formation shows good hydraulic sorting; and (5) a&#13;
  395. significant volume of ash was deposited together with&#13;
  396. the coarsest pyroclasts.&#13;
  397. The bed forms in units A and B suggest deposition&#13;
  398. from lithic-rich and pumiceous, respectively, submarine&#13;
  399. gravity currents. In unit C, the coarse (up to 6.5 m)&#13;
  400. pumice clasts are set in matrix that grades upwards from&#13;
  401. diffusely stratified, fine (1–2 cm) pumice clasts at the&#13;
  402. base to laminated shard rich mud at the top. The coarse&#13;
  403. pumice clasts in unit C were settled from suspension and&#13;
  404. the framework was progressively infilled by fine pumice&#13;
  405. clasts from waning traction currents and then by watersettled ash. The FPB displays important features of the&#13;
  406. products of submarine explosive eruptions that result&#13;
  407. from the ambient fluid being seawater, rather than volcanic gas or air. In particular, submarine pyroclastic&#13;
  408. deposits are characterised by the presence of very coarse&#13;
  409. juvenile pumice clasts, pumice clasts with complete&#13;
  410. quenched rims, and good hydraulic sorting.</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 original publication is available at www.springerlink.com</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Submarine explosive eruption, Volcaniclastic&#13;
