Field Trip Introduction
The Guadalupe and Hueco Mountains are exquisite natural laboratories for studying the stratigraphy, depositional facies, and diagenetic overprint of Permian platform and reef carbonates. Well-studied outcrops from these two classic localities serve as important analogs for other areas where the data is more limited. In addition, studies from the two areas have had immediate application to subsurface hydrocarbon exploration and exploitation efforts in the immediately adjacent Permian Basin.
Our field trip of three days will emphasize the stratigraphic framework, facies, and diagenesis of a Lower Permian (Wolfcampian) low-relief carbonate platform outcropping in the Hueco Mountains and an Upper Permian (Guadalupian) steep-rimmed platform of the Guadalupe Mountains. We invite questions and discussion at all field stops, as our group has diverse backgrounds and interests and any discussion will be beneficial to all.
The focus of the trip in the Hueco Mountains is on the evolution of the shelf-margin architecture and fauna! change. The exposures allow us to view the architectural elements of a prograding and retrograding shelf margin in ice-house conditions as well as the biotic response to environmental change. A relevant part of the exposure to visit is the facies variability both temporally and laterally.
Our emphasis in the Guadalupe Mountains is on the Capitan margin, as well as the related shelf and basin deposits. Large-scale outcrops like that of McKittrick Canyon offer an unparalleled view into the inside of a progradational platform, and we hope you will agree that the hike up the Permian Reef Geology Trail presents an
