Summary(Plain Language Summary, not published)
The Rapid Creek Formation consists of manganese- and phosphorus-rich ironstones that were deposited within an ancient ocean basin that is now exposed in the northern Richardson Mountains. Most researchers have focused on the unique mineral assemblages within these rocks, but little work has been done to better understand the reasons for their existence. This study aims to determine the origin of the Rapid Creek Formation by investigating the physical and chemical environments using a combination of geological and geochemical tools. This poster presents preliminary mineralogical and geochemical data and sets the stage for future studies.
