Abstract
Joint Systems Along the Northeast Margin of the Mississippi Interior Salt Basin, Alabama
Jack C. Pashin and Andrew K. Rindsberg
Geological Survey of Alabama, P.O. Box O, Tuscaloosa, AL 35486
ABSTRACT
Joints are commonly overlooked structures in Mesozoic-Cenozoic strata of the eastern Gulf Coast basin, yet significant hydrocarbon accumulations are in fractured and conventional reservoirs in this area. Two orthogonal joint systems are developed in Cenozoic strata along the northeastern margin of the Mississippi interior salt basin. System 1 joints strike subparallel to salt-related faults and fold axes. System 2 joints strike parallel to many modern hillslopes and appear to postdate regional faulting. System 2 joints apparently are forming in response to neotectonic stresses associated with regional unroofing and valley incision and probably do not extend downward to reservoir depths (~1,000 to 4,000 m). Orientation data suggest that system 1 joints formed in the same regional stress field as the salt-related faults. Therefore, system 1 joints and cross joints are predicted to exist at reservoir depths where they may form permeability pathways affecting hydrocarbon recovery.
