Project Description
In order to define stress orientation in the Antarctic interior, we have examined young volcanic cones found within Cenozoic volcanic provinces of the McMurdo Volcanic Group. Volcanic cones were mapped on regional satellite imagery using a combination of previous mapping, aerial photography, and digital photography and video taken from helicopter.

The volcanic cone data sets include:
1) maps showing cone locations and shapes,
2) 40Ar/39Ar geochronological data for individual cones, and
3) digital photographs of individual cones.

These data will be integrated with other geologic and geochronologic data in order to interpret stress field orientation in southern and northern Victoria Land. The data sets are available from the project investigators. Detailed description of the data sets and interpretations made from them can be found in published abstracts and manuscripts in preparation.
