Structural Geology Of The Brentwood-St. Paul Area, Northwest Arkansas, Mikel R. Shinn Jan 1978

Structural Geology Of The Brentwood-St. Paul Area, Northwest Arkansas, Mikel R. Shinn

Journal of the Arkansas Academy of Science

Photogeologic and field mapping of a 530 mi² area in southeastern Washington and southern Madison Counties, Arkansas, indicates that post-Atoka structural deformation occurred primarily through differential uplift of basement fault blocks. Northeast and east trending basement faults and fracture systems are present. Northeast trending features are related to the major fracture systems of the stable continental interior. They were initiated by shearing during Pre-Cambrian time and have subsequently acted as crustal zones of weakness along which mostly vertical movement has occurred. East trending basement faults may have originally developed as a result of tension between the stable Ozark uplift and …
