Title: Similarity of Surface Geology in Front Range of Sierra Madre Oriental to Subsurface in Mexican South Fields

Author(s): Lewis Burnett Kellum (2)

Abstract:

The eastern range of Sierra Madre Oriental, lying west and northwest of the Tampico embayment, is compared with the buried Tamasopo ridge of the Mexican South fields. Observations made at many points along the mountain front are described. A basalt flow associated with the front at one locality and several plugs east and west of it were noticed. At the western entrance to Guayalejo Canyon the El Abra phase of the Middle Cretaceous limestone is overthrust upon the Tamaulipas phase along a plane parallel with the bedding.

The subsurface conditions along the Tamasopo ridge of the Mexican southern district are briefly outlined. The structure and stratigraphy in the area of this buried ridge are very similar to the structure and stratigraphy of the eastern front of Sierra Madre Oriental. The two ridges are interpreted as similar mountain arcs formed on opposite sides of a basin of subsidence during Middle and Upper Cretaceous and Tertiary time.
