... correlations, the trilobites from new collections from the upper Nounan Dolomite to lower St. Charles Formation at Smithfield Canyon are reported herein and integrated with the previously reported taxa. Trilobite assemblages indicate that the upper Cedaria to the Ellipsocephaloides biozones (Miaolingian Series...

... by intracrystalline glide. In the central part of the study area, the Cambrian Maxfield, Ophir, and Nounan Formations are complexly folded and faulted below the Willard thrust. Plastic deformation is largely restricted to a 5- to 10-m-thick limestone mylonite in the Maxfield Formation, with cataclastic deformation...

... and chemostratigraphic correlations and refine the upper Cambrian geologic time scale. The SPICE in northern Utah, USA, was first reported by Saltzman et al. (2004) and is recorded in the upper Nounan Formation ( Cedaria to Dunderbergia biozones) and overlying lower St. Charles Formation ( Dunderbergia...

... ). At Nounan narrows, the Bear River crosses a normal fault that juxtaposes limestone of the Triassic Thaynes Formation to the north with gravel of the Wasatch Formation ( Oriel and Platt, 1980 ). Although the geomorphic expression of this fault is weak, it marks the northernmost extent of Quaternary normal...

... source for coeval Worm Creek Quartzite. In this paper we refer to the Worm Creek Quartzite Member of the St. Charles Formation and underlying sandstone in the top of the Nounan Dolomite as the “Worm Creek sandstone.” This link suggests that instead of a tectonically quiet subsiding margin during...

... Frederick A. Sundberg, Hannah R. Cothren and Carol M. Dehler Cambrian trilobites from the Nounan Dolomite and lower St. Charles Formation (upper Marjuman to lower Sunwaptan; Miaolingian to Furongian Series), Smithfield Canyon, northern Utah 567 Mansoureh Ghobadi Pour, Leonid E. Popov and Mohammad-Reza...

... wave base on the shelf. Lithofacies appear to be arranged in coarsening-upward packages 0.1-5 m thick. Stratigraphically above this ∼30-m-thick, clean subtidal carbonate succession (Nounan Formation; Fig. 4 ), siliciclastic sand is present over a 5-m interval approaching the contact with the Worm...
