Tidal and Shallow Marine Influence on
Deposition of the Woodbine Formation in
North Central Texas as Evidenced by

ABSTRACT
Outcrop studies of the Woodbine Formation throughout north Texas and a study of the USGS GC -2 core taken on Cedar Ridge suggest there are very defined shallow marine and tidal signatures present to include tidal point bars, quartz rich compound sand dunes, fiddler crab deposits, fully marine animal trace fossils such as anemones, horseshoe crabs, lobsters, shrimp and annelids. We also find evidence of a forest fire in the Woodbine.
As the Woodbine shorelines gave way and drowned under the deep water Eagle Ford seaway a very pronounced and well preserved marine transgressive surface is marked by oyster clasts and cement ground.
This talk will provide participants an introduction to a future ETGS geology field trip to Woodbine outcrops!!!
BIOGRAPHY
Bo Henk has been an exploration geologist since graduating in 1981 with a Masters from TCU. He has worked in conventional reservoirs in the US and Internationally and has lived overseas for 7 years in Indonesia. He crossed over to the dark side in 1997 where he spent His last three years at Arco in the research division working on bioturbated reservoirs and focusing on Ichnology He spent a year in Edmonton working under George Pemberton and developing the field of reservoir ichnology.
Since 2000 he has been with Matador and Pioneer in the US shale plays - active in almost every one of them and was an early core specialist in understanding them. Bo is also a die hard field geologist and has led many field trips to South Texas, Big Bend, Guadalupes, Sacramento Mtns the Texas Hill Country and Western Interior Seaway.
He is a local specialist on the Woodbine in outcrop in the North central texas and has led many TCU, GSA and AAPG trips to Lake Grapevine.
Bo is an adjunct professor at TCU and he and Dr Richard Denne have three MSc students working on the Woodbine and Austin Chalk.
