Abstract

Conodont microfossils representing many species are common in Cambrian through Triassic age marine rocks. These microfossils are important geologic time indicators and are used for local, regional, and global correlations. One goal of this study is to identify the conodont species preserved within the first 55 meters of the Lower Ordovician (~488- 469 Ma) Garden City Formation located in northeastern Utah. The conodont biostratigraphy developed through this project will enable the high resolution (meter scale) correlation of the Garden City Formation of northern Utah with rocks of the Pogonip Group in western Utah. The second goal of the project is the development of predictive models for the sequence stratigraphic architecture of the Garden City Formation based on the recognition of correlative surfaces reflecting eustatic oscillations common to both the Garden City Formation and the Pogonip Group. This project is being conducted in conjunction with the ongoing research of Colter Davis (Geology Master's Student) and Kenny Kehoe (Geology Undergraduate Student).
