Current Projects

  • Emplacement mechanism, paleoenvironment of formaiton, and lithification/fluid migration history of Neoproterozoic injectites and source rocks, Colorado Front Range
  • Integrated structural and seismological NSF EarthScope research in the Bighorn Mountains, Wyoming: Formation of basement-involved foreland arches

  • Brittle faults and kinematics of the Laramide Orogeny
  • 1.4 Ga tectonism in the Southern Rockies: Evidence from high temperature domains in Colorado and New Mexico
  • Development of geospatial resources for geological mapping of West Antarctica, ongoing collaboration with Polar Geospatial Center that emphasizes undergraduate research mentoring
  • West Antarctic rift system and Cretaceous tectonics of Gondwanaland (field studies in West Antarctica and in New Zealand)
  • Cordierite, (Fe, Mg) 2A14Si5018 — diverse aspects; see below

Colorado College has another professor by the name of Siddoway, and you guessed it, the two of us are married. Mike teaches Mathematics and serves as Associate Dean of the Faculty. Maybe you’ve read through this whole page and are completely confused because you are looking for the Prof. Siddoway who studies module theory, commutative rings, computational algebra, and the history of mathematics! To reach Mike, email him at msiddoway@coloradocollege.edu.
