Temporal Evolution of Fluvial Style in a Compound Incised-Valley Fill, Ferron “Notom Delta”, Henry Mountains Region, Utah (U.S.A.)

Nonmarine sequence stratigraphic models hypothesize systematic changes in fluvial style within individual sequences and across sequence boundaries, based largely on mudstone–sandstone ratios. The main purpose of the paper is to evaluate the validity of these models by documenting facies relationships and detailed bedding architecture of bar and channel deposits as well as mudstone–sandstone ratio within a compound incised-valley fill at the top …
