Buried impacts on Mars, Mars/Earth Comparative Volcanology, and new
features in interactive software were the topics of presentations by three
members of the Geodynamics Branch at the Geological Society of America
Annual Meeting October 26-31, 2002 in Denver, CO. Herb Frey organized
and chaired a special topical session "Early Mars" in which he presented
an introductory overview, a co-authored paper for his daughter Erin on
"Evidence for Buried Crust Older than the Oldest Observed Surface Units
on Mars" (Frey, Frey, Hartmann and Tanaka), and his own paper on "Large
Buried and Visible Impact Basins on Mars: Total Population Ages of the
Highlands and Lowlands". GSA did a press release on these two papers. |
