Abstract

The writers offer two typical sections of the Texas Gulf Coast, one from Fayette County to Matagorda County and another from McMullen County to Nueces County, based on the electrical logs of wells drilled in the line of the sections. Correlation from well to well is based on the electrical characters of the several formations, in addition to their foraminiferal content. The several formations are traced through in the respective sections from the deep underground to the surface. Attention is called to the presence of the marine shale Oligocene wedge in the subsurface not represented in the surface section. Attention is likewise called to the inaccurate correlation of the so-called subsurface Frio with surface Frio formation. Suggestion is made that the four stratigraphic units disclosed by the subsurface section, not present in the surface section, be properly named.
