Structural data: brittle faults for the Ford Ranges, Marie Byrd Land, Antarctica

The geological data sets for the Ford Ranges of western Marie Byrd Land include: - Structural measurements for minor brittle faults, fracture arrays, and dike arrays - 40Ar/39Ar geochronological data for mafic dikes and volcanic rock samples - Geochemical analyses (major, trace, and isotope) for Pleistocene basalts - Geological map of the Ford Ranges [includes revisions to USGS maps A-6, A-7, A-11; Wade et al. 1977, 1978] Data exist for nearly all mountain ranges and nunatak groups in the Ford Ranges.

All data are in Excel Worksheet format. The geology data were collected during a joint geology/aerogeophysics program designed to address questions of crustal structure and tectonic development along the eastern Ross Sea margin. The objective of the geological field research program, conducted during 1998-99 and 1999-2000, was kinematic analysis of mesoscopic structures, including brittle faults and dikes, in the ice-covered region where major structures are concealed.
