Abstract: The Glen Rose Section in the Canyon Reservoir Area
Comal County, Texas
Comal County, Texas
By
University of Texas, M. A. thesis, August, 1966
The area lies in the western edge of the Balcones fault system near the
eastern margin of the Edwards Plateau. En echelon, down-to-the-coast faults
repeat section which is well exposed in the rejuvenated, youthful topography.
The nearly horizontal Cretaceous strata range in age from Middle Aptian to
Middle Albian and are covered in some places by Quaternary alluvium and
colluvium. The concept of physically defined time-stratigraphic units of
sub-series
rank is useful in understanding the stratigraphic relationships within the
Trinity and Fredericksburg Divisions.
Laterally persistent, essentially synchronous sedimentational units of the
Glen Rose Formation weather into a diagnostic alternating bench and slope topography.
Deposition took place in an extensive shallow back-reef sea formed
behind the Stuart City reef. The Glen Rose of the report area is separated into
twelve locally recognizable subdivisions. End_of_Record - Last_Page 19--------
