Title: An integrated geophysical study of basin structure in the Van Horn segment of the Rio Grande rift

Abstract

The Rio Grande Rift is a major late Cenozoic continental rift which trends north-south from Colorado to West Texas where it takes an abrupt south-west turn. A series of basins then follow the Texas-Mexico border passing through the Big Bend Area into Mexico. This rifting zone produced a series of bolsons: Hueco Bolson, Red Light Bolson, Eagle Flat, Green River Bolson, and Ryan Flat being the most predominant of the area. The target of this study was the area southeast of the Hueco Bolson; the Red Light and Green River Bolson is an intermontane basin being bounded on the west by the Eagle Mountains and on the east by the Van Horn Mountains. The Red Light Bolson is nested between the Quitman and Eagle Mountains. Through the use of gravity data, drill hole information and other related geophysical information, the subsurface structure of this region was investigated. A broad gravity low dominates the region, but does not correlate well with late Cenozoic features. Drilling data suggest that this low is due to thick Cretaceous strata. The Green River Bolson is associated with a north-south trending gravity low suggesting it contains considerable Cenozoic fill.
