SCOPE AND PURPOSE
This workshop will address how physical observations of craters, both on Earth
and on other solid bodies of the solar system, can be combined with the results from modeling of
impact cratering for a better understanding of the impact cratering process.
The main goals of the workshop are to reconcile physical observations with theoretical and
experimental modeling of impact processes, and to point out areas that future studies should focus on to improve
the observation/modeling connection.
A technical report that includes workshop overviews and a synopsis of the results of the meeting will
be produced and distributed in electronic format. Authors will be allowed to submit revised versions
of their abstracts during a limited time period. Another potential product of the workshop is the
production of a journal special issue with invited synthesis papers and additional submitted papers.
ALL ABSTRACT SUBMISSIONS MUST DISCUSS BOTH MODELING AND OBSERVATIONS, either in
the context of observations necessary to evaluate impact models or how particular observations
constrain the impact process.
TENTATIVE WORKSHOP SCHEDULE
The morning sessions will run from 8:30 a.m. until 12:15 p.m., and afternoon sessions will run from 1:30
until 5:15 p.m.
The opening session will include two
45-minute opening presentations (35-40 minutes plus questions), one by a prominent model-oriented scientist
and the other by an observation-oriented scientist, under the broad topic of "What I Hope to Get Out of
this Workshop."
A 2-hour session on "Rock Properties that Need to be Known
for Theoretical Modeling" will follow the opening session and will have two 30-minute invited talks introducing the topic.
A panel-led discussion will follow on samples that need to be taken in the field, sample analyses
that need to be done, and what geologists should be looking for in the field.
The five remaining workshop sessions will include the topics below. There are obviously
more potential topic possibilities than available sessions, so some combining of topics will be necessary.
This list is subject to change based on submissions and input from attendees.
- Thermodynamics of impact cratering: shock-wave passage, melt/vapor production,
post-impact thermal state.
- Can the mass and composition of the impactor really be determined for a terrestrial crater?
- How is the structure of a complex crater created?
- Oblique impact effects, and ejecta emplacement. Can the direction of impact really be determined
for a terrestrial crater?
- The effects of target properties on the cratering process. Topic includes target layering and
target composition.
For each of these sessions we envision two invited talks of 30 minutes, one by a modeler and one by
an observationalist, with the remainder of the talks as contributions. Each invited talk will be followed
by 10 minutes for discussion, and a 3040 minute general discussion session at the end of each session.
A two-hour poster session is scheduled for the evening of the first day, but posters will remain on
display throughout the entire meeting.
The workshop will be closed by a three-hour wrap-up session consisting of a panel-moderated discussion.
TRAVEL ASSISTANCE
Some funds will be allocated to provide travel assistance to invited speakers, students and recent PhDs.
