New evidence for tectonic uplift in the Diablo Plateau region, West Texas
The National Geodetic Survey completed approximately 170 km of releveling in the Diablo Plateau-Salt Basin region during the fall of 1977. The survey was specifically designed to detect possible vertical crustal movements in the area. The new releveling measurements confirm contemporary uplift of the region and suggest that uplift has been continuous for the entire time the movements were monitored (1934-1977). Although the precise mechanism responsible for the observed uplift is unknown, it is almost certainly of tectonic origin. The pattern of uparching is perturbed at the Salt Basin graben, indicating 4.2 + or - 0.3 cm of subsidence relative to its margins between 1958 and 1977.
