Determining The Depositional Environment Of Amherstburg Formation, Elizabeth Gaines

Honors Theses

The Amherstburg Formation is a unit that stretches from Ontario to Michigan and was deposited during the Devonian Period. The goal of this project was to determine the depositional environment of the Amherstburg Formation. Facies associations were defined based on observations from three cores in northern and southeastern Michigan and later grouped into facies associations. The four facies associations were reef rubble, lagoonal, lagoonal and reef-rubble, and lagoonal and peritidal environments. These environments were deposited as laterally adjacent environments along a ramp shelf in a humid tropical climate. Sea level was relatively high during the deposition of the Amherstburg Formation. …
