Structural, petrological and geochronological data from Fosdick Mountains, Marie Byrd Land
Entry ID: OPP0338279_MBL_FosdickMtns


Summary
Abstract: GIS-based 3-D relational framework of geological and structural contacts, and geophysical provinces for a 16,000 km2 region ("3D geological map") of Marie Byrd Land, West Antarctica. The resource consolidates bedrock geology maps,airborne geophysics data, structural data, geochronological data, rock sample sites, satellite images and aerial photographs. The database is to be published as a dynamic GIS by the new Antarctic Geospatial Information Center (AGIC) at the University of Minnesota (collaboration of Siddoway and Morin), http://www.agic.umn.edu .

Rock sample collections from Fosdick Mountains, Marie Byrd Land; predominantly migmatite gneisses and plutonic rocks, with geochronology/thermochronology and geochemical data for selected samples
Sample numbers and descriptions are entered in the System for Earth SAmple Registration (SESAR) registry at http://www.geosamples.org , assigned an IGSN number, and can be located in through the online search routine. Researchers who have need of physical material can contact csiddoway@coloradocollege.edu with explanation and request to acquire more detailed descriptions, isotopic data or sample material for analytical work.

List of peer-reviewed publications based on the funded research.

Teaching aids (undergraduate level): Digital photographs illustrating migmatite textures and macroscopic elements of gneiss dome architecture, together with photomicrographs of metamorphic textures. Digital photo resource of glacial features. The photo collection can be made available on CD, upon request.
