Ferrar Dolerite Upper Taylor Glacier Region
Listed in NASA Earthdata CMR
This set of data describes Ferrar Dolerite rock samples collected during the 2002-2003 Antarctic field season from the Upper Taylor Glacier and Convoy Range regions of southern Victoria Land.
Description
The rock collection includes samples from eighteen sites (outcrops along the escarpment extending from Mt. Feather to Windy Gully, Rector Ridge, East Beacon, Pearse Valley, Pandoras Spire, Fris Hills, Mt.
Gran, Elkhorn Ridge) that include both smaller dikes and sills and regionally prominent intrusions (Basement Sill and Peneplain Sill). At each site, 20 to 60, 2.5 cm diameter, 10 cm long, oriented drill cores were collected over the interval of 2-3 meters from the intrusive contacts. Rock magnetic properties (anisotropy of magnetic susceptibility and natural remnant magnetization) have been measured at Byrd Polar Research Center, Ohio State University.

The collection also includes 5 to 10 oriented hand-samples of contact material from each site that have been used for petrofabric analysis and geochemistry. Samples have been analyzed for major and trace elements by XRF at Southern Connecticut State University. Orientation of mesoscopic structural features along the contacts (fingers, grooves, cusps) have been recorded in the area extending a few hundred meters away from each of the drilling localities.
The larger scale architecture of the intrusive system providing connections between sample sites, has been documented by field sketches and photo mosaics.
