Assessing the Effect of Impact Shock on Water in Amphibole: Implications for
the Martian Meteorites

Hydrous phases in the martian meteorites, kaersutite (Ti-rich amphibole) and
apatite, have unique and unusual water contents (low) and H isotopic
compositions (D-rich). Understanding the origins of the water contents and
H isotopic signatures of these phases is important to understanding the
water budget of Mars and the interactions between interior, hydrospheric and
atmospheric water reservoirs on Mars. One potential factor influencing
water in martian meteorite hydrous phases is impact shock, the very process
that brought the martian meteorites to Earth. We have investigated the
effects of impact-induced devolatilization on the water content and H
isotopic composition of amphibole in order to assess the degree to which
water in martian amphibole was influenced by the shock process.Participation Instructions

The Director’s Seminar series features talks from scientists who are invited by the NAI Director to present their research results to the community. A primary goal of the seminars is to encourage interdisciplinary collaboration across NAI teams and within the astrobiology community at large.
Team Overview Seminars describe the work of the fourteen NAI teams and NAI Central. They offer an opportunity to find out more about the science, E/PO and other activities being performed by the NAI teams and the NAI Central office.
The Forum for Astrobiology Research (FAR) provides an opportunity for graduate students to present their research results and to meet as a student community for networking and mutual support.
The University of Washington seminar series is hosted by the NAI Virtual Planetary Lab (VPL) team from the UW campus in Seattle.
