GSA Bulletin (1992) 104 (10): 1376–1385.
...MARTIN G. MILLER Abstract Field relations in the footwall of the Badwater Turtleback fault provide evidence that macroscopically ductile deformation was directly responsible for early stages of brittle faulting during extensional denudation. Footwall rocks, which are typically mylonitie, consist...

...Martin G. Miller Abstract The late Cenozoic Badwater Turtleback fault separates an upper plate of volcanic and sedimentary rocks from a lower plate of predominantly mylonitic plutonic and metamorphic rocks. The Turtleback fault, however, is not a single continuous surface, but consists of at least...

... are strikingly similar to the characteristics of the Amargosa Chaos of the Death Valley area; moreover, the form of the fault contact resembles the turtleback domes associated with the chaos at Death Valley. Similarities to areas of gravity sliding, including a possible erosion surface overriden by the thrust...

...HARALD DREWES Abstract Turtlebacks are smooth, curved surfaces, which form north-northwestward-plunging elongate domes on the east side of Death Valley. These surfaces are roughly parallel to bedding or foliation of anticlines in Precambrian schist, gneiss, and marble. Late Cenozoic fan and playa...
