Joint and Lineament Patterns across the Midcontinent Indicate Repeated Reactivation of Basement-Involved Faults

Joint networks hosted in successively younger rocks, developing as a result of forced (trishear) folding of a rock mass above a deep-seated fault, can be used to infer the reactivation history of that deep-seated fault. This study aims to use joint networks in Pennsylvanian, Permian and Cretaceous rocks to document evidence of reactivation on basement faults during the Paleozoic and Mesozoic of Nebraska and Kansas. The most prominent basement features in southeast Nebraska and northeast Kansas are oriented NE-SW, likely related to the Midcontinent Rift System and Nemaha Uplift, and oriented NW-SE, likely related to fabrics from the Central Plains Orogeny. These features are well defined in the potential fields data. Joint patterns in the study area show an E-W oriented trend, as well as clearly discernable NE-SW and subsidiary N-S and NW-SE trends. The E-W trend is interpreted to be related to far-field stresses from Laramide and Ancestral Rocky Mountain orogenic events, whilst the NE-SW trend is interpreted to be related to subtle reactivation on the Mid-continent rift and related faults, observed in basement data. These movements produced stresses of sufficient magnitude to produce joints in the post-rift rock units, but not sufficient to generate shear fractures. Similarly, the~N-S and NW-SE joint trends are taken as evidence of subtle reactivation on the Nemaha Uplift and Central Plains Orogeny systems, generating joints by the formation of forced folds. This contribution therefore provides a convincing case study of the value of coupled potential fields and surface feature studies in discerning buried tectonic trends and subtle reactivation thereon.

“…Buckling of the whole lithosphere due to plate boundary stresses was first suggested for oceanic lithosphere (e.g., McAdoo and Sandwell, 1985), and has also been proposed for continental lithosphere on 100 km wavelengths that may be determined by the mechanical strength of the mantle (Tikoff and Maxson, 2001).…”

“…Mid-continental arches, sometimes referred to as "plainstype folding", developed in the region now occupied by Kansas, Minnesota, Nebraska, North Dakota, Oklahoma and Texas. The origin of mid-continental arches is estimated to be at least Late Paleozoic, even older, and they were probably activated during the Laramide orogeny (Bunker et al 1988, Tikoff & Mason 2001. …”

The late Paleocene and early Eocene megafossil floras in North America are found primarily in the Williston, Green River, Powder River, Bighorn, and Alberta Basins of the northern Rocky Mountains and Western Interior. A few rare sites occur in the Mississippi Embayment of the Southeast. In contrast to the abrupt floristic changes seen at the K/T boundary, these floras document a gradual transition in species turnover, or, in the case of the Bighorn Basin, a long-term decrease in taxonomic diversity. This gradual transition is also in marked contrast to the rapid speciation among mammals of the early Eocene. Both preservation, and ability to place these floras within a temporal scale, determine how useful they are in assessing floristic changes across the Paleocene-Eocene transition. In some regions such as the Bighorn Basin of Wyoming precise stratigraphic control has allowed for documentation of paleoclimate change at a highly resolved temporal scale. At others, such as the Almont flora of the Williston Basin in North Dakota, exceptional preservation has provided the basis for describing individual taxa with the precision necessary to better understand their evolutionary and biogeographical histories. This study examines well-known plant taxa in the late Paleocene and early Eocene in the context of their depositional settings and temporal and spatial distribution. Integration of paleoecological and taxonomic studies is critical to understanding the evolutionary and depositional history of early Paleocene vegetation of North America
