Dr. Gary Gianniny -
Sedimentologist
Professor Gary Gianniny is an educator and geologist at Fort Lewis College in Durango Colorado. He and many of his research students have focused studying the sequence stratigraphy and porosity evolution in the Pennsylvanian and Mississippian carbonate and clastic strata in the Paradox basin and Grand Canyon region. Gianniny earned his MS. and PhD at the University of Wisconsin- Madison. His doctoral research focused on sequence geometries and facies distributions in the Pennsylvanian Hermosa Group with implications for predicting reservoir compartmentalization and heterogeneity. Postdoctoral work at Idaho State University applied a sequence stratigraphic lens to aquifer heterogeneity inter-basalt flow sediments on the Snake River Plain. Since 2014 Gianniny and 10 of his students have studied the sequence stratigraphy and porosity evolution in the Mississippian Leadville and Redwall limestones. Gianniny also studies the impacts of recent reduced river flows and sedimentation. Consulting work on oil, gas, carbon-dioxide, and helium reservoir characterization includes clastic and carbonate strata in India, the Middle East, offshore Brazil, the Paradox basin, and other regions in North America. He has twice served as the President of the Four Corners Geological Society and more recently the Vice Chair and Chair of the Sedimentary Geology Division of the Geological Society of America (2015-18).
