Bill Dunne and his students examine mesoscopic and microscopic structures in sedimentary and low-grade metamorphic rocks to determine regional tectonic histories and deformation behaviors. Specific problems that they are interested include: (1) development of blind foreland thrust belts; (2) formation of fault-related folds; (3) the overall contribution of outcrop-scale deformation to regional shortening; (4) low-temperature deformation of quartz arenites including diagenesis; (5) variation in shortening responses in a stratigraphic sequence as a function of lithology; (6) development of regional orthogonal joint patterns; and (7) improved characterization of joint patterns.
The tools that Bill and his students use to tackle these problems include: (1) strain analysis, (4) small-scale geological mapping of features such as fault-related folds, joints on bedding pavements or cleavage distributions, (3) cross-section construction at both regional and outcrop scale including section balancing; and (4) one-dimensional and two-dimensional sampling of joint patterns.
At present, Bill is not recruiting graduate students due to administrative responsibilities within the University. However, he continues to serve on the committees of graduate students working with other faculty members in the department and to serve as an editor of the Journal of Structural Geology.
