New research authored by Center Interim Director Devin Schrader and University of Arizona Associate Professor Tom Zega uses chemical and petrographic analyses of iron sulfides to determine the metamorphic type of the host LL chondrite and constrain alteration conditions. These findings can be applied to sulfides in samples returned by the Hayabusa mission from asteroid Itokawa, as well as those in other LL chondrites.
The article, Petrographic and compositional indicators of formation and alteration conditions from LL chondrite sulfides, appears in the journal Geochimica et Cosmochimica Acta, and is currently available online, here.
