CHEMOSTRATIGRAPHY AND PALEOENVIRONMENTAL SIGNIFICANCE OF THE PENNSYLVANIAN SMITHWICK FORMATION, NORTHEN LLANO UPLIFT REGION, TEXAS
The current interest in the evaluation and characterization of the Smithwick Formation is based on good core and well-log coverage, revealing its importance as an analogue for studying similar shale sections, and to better understand the structural and depositional constraints of the FWB, and its Pennsylvanian marginal-marine conditions. The characterization and better understanding of the the Smithwick Formation provides depositional and paleoenvironmental details that can be used in hydrocarbon exploration and shale geochemistry. The purpose of the present study is to acquire and analyze geochemical data from two drill-cores retrieved from Brown and McCulloch counties, in Central Texas, and to correlate these drill-cores to previously published studies and well data. The multi-proxy approach can lead us toward a better understanding of the local subsurface geology, geochemical patterns, and environmental processes that occurred during the Early Pennsylvanian in Central Texas
