Broken foreland basins are caused by crustal-scale contractional basement structures that compartmentalize (or break) a contiguous retroarc or collisional basin into smaller disconnected basins. differ from their unbroken counterparts in deformational, depositional, and geodynamic framework. Whereas (unbroken) generated mainly regional flexural loading due to shortening of supracrustal cover strata uppermost organized ramp-flat thrust systems, broken governed principally isolated topographic...
Dinoceratans or uintatheres are a phylogenetically enigmatic clade of extinct mammalian herbivores that were among the first eutherians to obtain truly massive body size. Uintatheres reasonably common elements North American mammal faunas spanning from late Paleocene (late Tiffanian, Ti-5) through middle Eocene (Uintan). However, prior records have been geographically restricted central Rockies, Texas, and California. Here, we report occurrence uintathere Kishenehn Formation in northern...
Western North America is the archetypical Cordilleran orogenic system that preserves a Mesozoic to Cenozoic record of oceanic Farallon plate subduction-related processes. After prolonged Late Jurassic through mid-Cretaceous normal-angle subduction produced western American batholith belt and retroarc fold-thrust belt, period low-angle, flat-slab during Cretaceous−Paleogene time caused upper deformation migrate eastward in form Laramide basement-involved uplifts, which partitioned original...

The cored succession is dominated lacustrine marginal deposits ranging stratified...
Abstract The southern Central Andes recorded retroarc shortening, basin evolution, and magmatic arc migration during Neogene changes in subduction. At 31–33°S, above the modern flat‐slab segment, spatial temporal linkages between thin‐ thick‐skinned foreland basement‐involved exhumation of main Cordillera, lower‐crustal hinterland thickening remain poorly resolved. We integrate new geochronological thermochronological data for thrust sheets fill with structural, sedimentological, passive...
The lacustrine oil shales of the Coal Creek Member Kishenehn Formation in northwestern Montana comprise a relatively unstudied middle Eocene fossil insect locality.Herein, we detail stratigraphic position fossiliferous unit, describe fauna locality and document its bias towards very small but remarkably pre-served insects.In addition, depositional environment is examined mineral constituents laminations that varves shale are defined.Fifteen orders insects have been recorded with majority all...
Abstract A source‐to‐sink analysis incorporating geochronometric and thermochronometric data from the Sevier fold‐thrust belt (SFTB) proximal synorogenic strata of Canyon Range Conglomerate (CRC) Indianola Group (IG) provides new insights into orogenic exhumation, erosional unroofing, interplay between thrusting coarse clastic deposition in Cretaceous Cordilleran foreland basin western North America.

The Kishenehn Formation of northwest Montana and southeast British Columbia hosts one the most prolific diverse assemblages fossil nonmarine mollusks in North America. More than 76 taxa, which 41 are newly described species, middle Eocene to early Miocene terrestrial aquatic gastropods have been collected described. This paper reports on discoveries made oldest part formation that is age southernmost Basin. Outcrops along Middle Fork Flathead River from this area yielded over 1400 specimens...

The Kishenehn Basin is a narrow, asymmetric graben, developed during an episode of crustal extension occurring from middle Eocene to early Miocene time .The Flathead listric normal fault system defines the northeast margin basin.The southwest either bounded by antithetic faults or onlapped strata.High rates basin subsidence and synextensional sedimentation resulted in immense thickness Eocene-early strata (stratigraphic thickness, -5000 m) relatively uninterupted depositional...
