PURPOSE OF CONFERENCE
The conference (formerly "Large Meteorite Impact and Planetary
Evolution") will bring together researchers working on a wide range of 
aspects of impact cratering with emphasis on large terrestrial and 
planetary impact structures and the ways in which they influenced 
planet formation and evolution. Of special interest are new 
observations and interpretations obtained from studies of the three 
very large terrestrial structures - Chicxulub, Sudbury, and Vredefort. 
Contributions dealing with the following topics are invited:

 - Impacts and Earth evolution
 - Impact structures and climate change
 - Role of target volatiles
 - Formation of melt sheets, melt breccias, and impact glasses in
        crystalline and sedimentary targets - melt sheets and melt
        breccias within the impactite sequence
 - Mass-movement of subsurface materials as revealed by
        macroscopic and microscopic observations from crater floors,
        mega-block zones, central uplifts, peak rings, and collar
        rocks
 - Impacts in marine environments
 - Impacts on other planets
 - Material response to hypervelocity impact - shock
        metamorphism
 - Geophysical signatures of planetary impacts
 - Economic significance of impacts
 - Experimental and numerical studies

PROCEEDINGS VOLUME
A proceedings volume presenting the results of the conference will be 
produced as a GSA Special Paper or similar publication.

TRAVEL ASSISTANCE
Moderate funds will be made available to students, recent graduates, 
and Ph.D.s who present results dealing with the topic of the 
conference. Students from developing countries are specifically 
encouraged to apply.
