Abstract

The intent of this guidebook is 1) to provide a geological overview of cyclical Neogene and Quaternary deposits of the North Carolina Coastal Plain, including phosphatic sequences that most strikingly document lithologic responses to recurring changes in sea level; and 2) to outline mining practices and environmental considerations related to the extraction of phosphate. The open-pit mine of Texasgulf, Inc. exposes a splendid stratigraphic section that will be supplemented by materials from drill cores located in the surrounding area. We hope that the following collection of papers will provide insight into the general geology, stratigraphy, paleontology and economic geology of this intriguing and complex succession of Upper Cenozoic sediments.

The first three papers describe the regional geologic setting (Hoffman), the basic mineralogy of phosphates (McClellan et al.) and the detailed geology of the phosphate mining district (Snyder et al.). Next is a series of papers describing the historical development of mining activities (Chamness), control of groundwater (Hird), mining procedures (Hird), utilization of spoils (Edwards) and environmental programs (Gilmore). The final paper, by Gilmore, describes specific points of interest at the Lee Creek Mine, briefly relating all of these topics to one another in order to present a unified picture of a complex, multifaceted industry.
