“…The following interpretations of characteristic lithofacies in the study area are consistent with recent studies on the stratigraphic relationship of Dakota Formation deposits in southeastern Nebraska and western Iowa by Brenner et al (2000) and Joeckel et al (2005). See Hamilton (1994) and Brenner et al (2000) for regional perspectives on the sequence stratigraphic relationships of the Dakota Formation.…”

“…The geographic relationship of the Jefferson County localities is along a northeast-southwest trend, one that is concordant with the depositional geometry of this portion of the Dakota Formation outcrop belt (Witzke and Ludvigson, 1994;Brenner et al, 2000). These relationships coupled with a pre-Dakota Formation topographic study of the region by Joeckel et al (2005) indicate these localities lay within the same paleo-fluvial/ estuarine valley.…”

“…This was followed by a relative decline in base level, as indicated by increasing grain size and local incision of overlying strata on the scale of 0.5 m ( Figure 5). Additionally, sphaerosiderite-bearing mudstones from the Bosewell Pit core are interpreted to be paleosol horizons that formed on interfluves in the same fluvial-estuarine system (Brenner et al, 2000;Joeckel et al, 2005).…”

U-Pb ages (n = 403) of detrital zircons from the Dakota Formation in western Iowa and eastern Nebraska provide evidence for westwardflowing fluvial systems that stretched from the Appalachian highlands to the western U.S. Cordilleran foreland basin during Albian-Cenomanian time. Approximately 78% of detrital zircon grains match the ages of Grenvillian (1.3-1.0 Ga), Pan-African (750-500 Ma), and Paleozoic (500-310 Ma) bedrock sources located within the present-day Appalachian Mountains. The presence of minor detrital zircon grains of Paleoproterozoic (2.5-1.5 Ga) or Archean age (>2.5 Ga) indicates that northern source regions in Minnesota, Wisconsin, and Canada did not contribute a significant volume of sediment, as had been previously interpreted. Based on similarities between detrital zircon signatures in the midcontinent strata and time-equivalent Cordilleran foreland basin strata, Appalachian sources may have contributed a previously unrecognized volume of sediment to the Albian-Cenomanian foreland basin system. Sediment flux from the Appalachian region to the Cordilleran foreland basin during middle Cretaceous time may have been related to increased uplift and exhumation due to passage over a mantle plume track.

Rinded iron‐oxide concretions: hallmarks of altered siderite masses of both early and late diagenetic origin

et al. 2012

Iron-bearing concretions are valuable records of oxidation states of subsurface waters, but the first concretions to form can be altered drastically during later diagenetic events. Distinctive concretions composed of heavy rinds of iron oxide that surround iron-poor, mud-rich cores are common along bases of fluvial cross-bed sets of the Cretaceous Dakota Formation, Nebraska, USA. Concretion rinds thicken inward and cores contain 46 to 89% void space. Millimetre-scale spherosiderites are abundant in palaeosols that developed in floodplain facies. Evolution of rinded concretions began when intraformational clasts were eroded from sideritic soils, transported, abraded and deposited in river channels. Alteration of siderite and formation of rinds occurred much later, perhaps in the Quaternary when sandstone pore waters became oxic. Dakota concretions are analogous to 'rattlestones' in Pleistocene fluvial channels of The Netherlands, and their rinded structure is analogous to that of iron-rich concretions in the aeolian Navajo Sandstone of Utah. In all three deposits, rinded concretions formed when pre-existing, siderite-cemented concretions were oxidized within a sand matrix. Unlike fluvial examples, siderite in the Navajo Sandstone was autochthonous and of late diagenetic origin, having precipitated from carbon dioxide and methane-enriched waters moving through folded and jointed strata. Iron-rich rinds formed in all these strata because concretion interiors remained anaerobic, even as oxygen accumulated in the pore waters of their surrounding, permeable matrix. Iron oxide first precipitated at redox boundaries at concretion perimeters and formed an inward-thickening rind. Acid generated by the oxidation reaction drove siderite dissolution to completion, creating the iron-poor core. Iron-oxide rinds are indicators of the former presence of siderite, a mineral that forms only under reducing conditions, during either early or late diagenesis. Siderite is vulnerable to complete oxidation upon exposure, so the distinctive rinded concretions are valuable clues that aid in deciphering diagenetic histories and for recognizing methanic floodplain palaeoenvironments and wet palaeoclimate.
