All the papers of EPSL Vol.289, issues1-2, 2010 (including Misawa's paper) would be downloadable for everyone (non-subscriber, too), as free copies. http://www.sciencedirect.com/science?_ob=PublicationURL&_cdi=5801&_auth=y&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&_pubType=J&md5=52c7e8b29221fe23b6fc7aa3ca3251f1 Katsu OHTSUKA ----- Original Message ----- From: "Paul Heinrich" <oxytropidoceras at cox.net> To: "Meteorite List" <meteorite-list at meteoritecentral.com> Sent: Monday, January 04, 2010 10:31 AM Subject: [meteorite-list] Two extraterrestrial dust horizons found in theDome Fuji ice core Misawa, K., M. Kohno, T. Tomiyama, T. Noguchi, T. Nakamura, K. Nagao, T.Mikouchi, and K. Nishiizumi, 2010, Two extraterrestrial dust horizons found in the Dome Fuji ice core, East Antarctica. Earth and Planetary Science Letters. vol. 289, no. 1-2, pp. 287-297. http://dx.doi.org/10.1016/j.epsl.2009.11.016 In part the abstract reads, "Two silicate-rich dust layers were found in the Dome Fuji ice core in East Antarctica, at Marine Isotope Stages 12 and 13. Morphologies, textures, and chemical compositions of constituent particles reveal that they are high-temperature melting products and are of extraterrestrial origin. Because similar layers were found approximately 2000 km east of Dome Fuji, at EPICA (European Project for Ice Coring in Antarctica)-Dome C, particles must have rained down over a wide area 434 and 481 ka." Mention is also made of these dust horizons in: Narcisi, B., J. Robert Petit, and B. Delmonte, nd, Quaternary Science Reviews, Article in Press, Corrected Proof http://dx.doi.org/10.1016/j.quascirev.2009.07.009 A related paper that is available online as a PDF fils is: Duprat , J., C.
