Discovery of a New Unique Water-rich Meteorite from Mars - Carl Agee (SE...
Μετάδοση με ζωντανή ροή στις 9 Ιουλ 2013
A talk by Carl B. Agee of the University of New Mexico
Northwest
Africa (NWA) 7034 is a new type of martian meteorite discovered in
Morocco in 2011. NWA 7034 aka "Black Beauty", nicknamed for its dark
shiny appearance, contains ten times more water than other martian
meteorites. This combined with its oxidation state which is highest
among martian meteorites, its anomalous oxygen isotope values, and its
early Amazonian age, make it an extraordinarily valuable specimen for
understanding surface processes, aqueous alteration, and
atmosphere/lithosphere exchange reactions that existed on Mars ~2
billion years ago.
Agee will show that Black Beauty appears to be
the first martian meteorite to match the surface geochemistry of Mars,
as seen by landers and orbiters, and as such, it has particular
relevance to the current Mars Science Laboratory mission at Gale Crater.
