Uncompahgre fault geometry : a seismic, field, and gravity study near Nucla, Colorado, Paradox Basin, USA
MetadataShow full item record
Seismic, well, field and gravity data are used to further understand the Uncompahgre fault near Nucla, Colorado, Paradox Basin, USA. The data help explain the complex sedimen- tary and structural history associated with faulting and salt flowage along the eastern margin of the Paradox Basin. Near Nucla, Colorado, 2D seismic lines document several episodes of thrust tectonics, sedimentation, and salt flowage associated with the late Paleozoic-age Uncompahgre Thrust. Prominent unconformities and disconformities within the Permian Cutler Group are vis- ible in the study area. Faults and unconformities ...
