Abstract
Depositional Setting of Upper Cretaceous-Lower Tertiary Currant Creek Formation, North-Central Utah
Abstract
Braided streams within a humid alluvial fan network largely deposited the Cretaceous through early Tertiary Currant Creek Formation in the northwestern Uinta Basin, northeast Utah. These fans extended into the north-central Utah foreland basin from the tectonically active Sevier orogenic belt on the west.
The synorogenic conglomerate ranges in type from boulder-sized clast-supported strata to pebble-and granule-sized matrix-supported conglomerate. The interbedded sandstone increases in textural maturity with distance from source areas. The sandstone composition ranges from quartz arenite to lithic arenite.
Conglomerate and sandstone that formed as longitudinal bars, channel fills or sieve deposits characterize the proximal fan facies. Distal facies consist principally of sandstone and finer grained clastic strata that were deposited within channels or overbank areas.
