Evaluation of subsurface Catahoula Formation in Natchitoches Parish, Louisiana
Subsurface Catahoula Formation samples were collected near Marco, Louisiana, by the US Army Corps of Engineers for the Red River Lock and Dam 3 investigation. Core samples were classified in the field by geologists and were analyzed in the lab for grain size, sorting, and mineralogy, compiled cross sections based on core and electric log data portray local stratigraphic facies of interbedded sands, sandy claystones, and claystones with occasional lignites. Paleobotanic analysis of leaf imprints (Myrcia sp. and Iva sp.) indicates a tropical, coastal/deltaic environment of deposition. Scanning electron microscope, petrographic, and x-ray diffraction analyses conducted on representative samples revealed major amounts of montmorillonite, kaolinite, illite, and cristobalite. These findings support the concept of rapid burial of coastal/deltic sand and clay bodies derived from eroded continental material and occasional volcanic sources.
