Autor: Thomas A. Ryer, Ronald W. Stanton, S.S. Crowley, Debra A. Dufek

Publikováno v: PALAIOS. 9:158

The maceral and palynological composition of the C coal bed (Upper Cretaceous), central Utah, was significantly affected by the periodic deposition of volcanic ash in the precursor peat mire. The coal bed contains four altered volcanic ash partings (

Cretaceous Stratigraphy of the Coalville and Rockport Areas, Utah

Autor: Thomas A. Ryer

Publikováno v: Utah Geology. 3:71-83

Cretaceous strata exposed in the Coalville and Rockport areas record the deposition and accumulation of terrigenous clastic sediments in alluvial-fan, fluvial, marginal-marine, and nearshore and offshore-marine environments. Marine sediments were dep

Deltaic Coals of Ferron Sandstone Member of Mancos Shale--Predictive Model for Cretaceous Coals of Western Interior: ABSTRACT

Autor: Thomas A. Ryer

Publikováno v: AAPG Bulletin. 63

Superb exposures of the Upper Cretaceous Ferron Sandstone Member of the Mancos Shale in southern Castle Valley, Utah, record rapid accumulation of clastic sediments in a suite of deltaic environments that existed along the western margin of the Inter
