Description:
This publication, consisting of four structure and correlation sections
across portions of the eastern Mogollon Slope region in east-central
Arizona, serves as a companion piece to the Arizona Oil and Gas
Conservation Commission subsurface structure maps G-6 (G-6a), G-7,
and G-8. It represents an attempt to present graphically structural and
stratigraphic information designed to facilitate future investigations of
the petroleum potential by industry.
PURPOSE AND SCOPE.
The principal purpose in publishing the sections is to provide petroleum
exploration geologists a graphic presentation of the subsurface
stratigraphy and structure revealed by most of the wells penetrating
basement rocks in the study area. Because of the widely diverse "picks"
of the top of the Pennsylvanian Naco Formation, as reported in published
literature and in well completion reports submitted to the Oil and Gas
Conservation Commission, emphasis in presenting stratigraphic data
on the sections has been placed on the interval from the base of the
Fort Apache Member of the Permian Supai Formation to the top of
pre-Pennsylvanian rocks. The petroleum potential of the marine
carbonates in this interval, in addition to those of the Fort Apache
Member of the Permian and pre-Pennsylvanian sections, has not been
evaluated adequately in this frontier area.
