GEOS 126 - Earth Time

HC NSMA

2 credits
Earth coalesced into a solid planet over 4.5 billion years ago and since then has undergone dramatic changes in landscape and environment. Ever wondered how earth scientists constrain the timing of tectonic, evolutionary, climatic, and human events in Earth’s history? This module introduces various (geo)chronologic methods to date events at a range of time-scales, from the Hadean to the Anthropocene, including U-Pb radiometric dating, thermochronology, cosmogenic nuclides, dendrochronology, and more. Field trip(s) required.

This course is appropriate for new students.
