Shallow fracture formation and fluid mobilization during diagenetically driven deformation: the Tertiary Badlands chalcedony vein and clastic dike systems of South Dakota and Nebraska - An undergraduate research project.

July 2009

This 3 year project is funded by the Petroleum Research Fund of the American Chemical Society, whose support we are grateful for. Drs. Harmon Maher and Robert Shuster are co-PIs. The focus of the project is to involve undergraduates in research on the genesis and patterns of chalcedony veins and clastic dikes found in the White River Group in South Dakota and Nebraska. We believe the veins are an example of structural diagenesis, which is deformation caused by the various changes sediments go through as they are buried, and which includes fracture network formation and fluid migration. This builds on previous efforts undergraduate research efforts, including a NSF funded STEM opportunity in 2004 and another in 2007.We would also like to take this opportunity to thank and acknowledge Dr. Rachel Benton, who helped with the permit process for the Badlands National Park.
