Mikayla Walker, “Flora and Fauna of the Pleistocene Oak Creek Formation Peat Deposits” Mentor: Scott Schaefer, Geosciences Late Pleistocene Oak Creek Formation deposits dated to 45,000 to 35,000 years old are exposed at Sheridan Park in Cudahy, Wisconsin. Sediments from…… Read More

Literature Review on the Ultrasructural Variation in Trilobite Exoskeletons

Haley Kempf, “Literature Review on the Ultrasructural Variation in Trilobite Exoskeletons” Mentor: Victoria McCoy, Geosciences Trilobites were extremely diverse and abundant arthropods, now extinct, with over 20,000 recognized species ranging in size from one mm to 72 cm. Unlike most…… Read More

Microstructural Analysis of Metabasites from the Southern Iberian Shear Zone

Valerie Rubalcava, “Microstructural Analysis of Metabasites from the Southern Iberian Shear Zone” Mentor: Dyanna Czeck, Geosciences Fault zones at depth are not widely investigated in situ because the area of interest is too deep and expensive to probe. At depth,…… Read More

Microstructural Observations Across the Southern Iberian Shear Zone

Dulce Hernandez-Blanchard, “Microstructural Observations Across the Southern Iberian Shear Zone” Mentor: Dyanna Czeck, Geosciences The interactions of tectonic plates cause deformation in rocks that result in a shear zone. A shear zone is a tabular zone of rocks that has…… Read More
