Gravity and subsurface investigation of the Presidio Bolson area, Texas

PDF Version Also Available for Download.

Description

An integrated geophysical-geologic study of the Presidio Bolson area was undertaken primarily using gravity measurements and deep drilling data. Over 2000 gravity readings were used to construct maps of the area and two-dimensional computer modeling of gravity profiles was used to derive earth models. These data outlined the major geologic features of the area and were dominated by Tertiary block faulting and volcanism. The main feature of interest was the Presidio Bolson, which is located in a major graben (Presidio Graben) over 1 km deep in the area near Ruidosa, Texas. These data also suggest that hot springs associated with ... continued below

The main feature of interest was the Presidio Bolson, which is located in a major graben (Presidio Graben) over 1 km deep in the area near Ruidosa, Texas. These data also suggest that hot springs associated with the Presidio Graben derive their heat from buried Tertiary intrusions associated with this graben or by deep circulation along the boundary faults of the graben.
