Depositional Complexities of Upper Pennsylvanian Fluvial-Dominated Deltaic Deposits, Skiatook Lake, Oklahoma

Lee F. Krystinik

AAPG Midcontinent 2021

Saturday, October 2nd

 Skiatook Outcrop

Course Description: This field trip documents the remarkable diversity of reservoir and seal deposits of the Upper Pennsylvanian (late Missourian to early Virgilian) river-dominated deltaic and interdeltaic deposits exposed around Skiatook Lake, northwest of Tulsa, OK.  The group will spend most of the day cruising on pontoon boats to examine a series of excellent coastal exposures ranging from marine shale to pro-deltaic event beds and delta-front turbidites to massive, amalgamated distributary-mouth-bar deposits, distributary channels deformed by dewatering and a sub-lacustrine gas seep coming out of these sands.  The trip will finish with beers and a social hour overlooking the lake.

Logistics: Bus departs from the Hyatt hotel at 8:00 AM and returns the participants to the hotel by 6:00 PM.  Lunch, snacks, and drinks will be provided during the trip along with a selection of beers at the end of the trip.

Field Trip Leader: Lee F. Krystinik
