... the inward movement of rocks in the uplift. Analogy with experimental craters and with other cryptoexplosion structures indicates that the uplift at Sierra Madera protruded into a crater (since destroyed by erosion) that was about 12 km across. Inasmuch as the rocks forming such uplifts are derived from...

...H. G WILSHIRE; KEITH A HOWARD; T. W OFFIELD Abstract Two main types of deformational breccia occur in the Sierra Madera cryptoexplosion structure: monolithologic breccias composed of shattered rock of a single lithology and mixed breccias composed of rocks of several lithologies. Monolithologic...

... of the Pedernal Hills. Pennsylvanian sediments were evidently restricted westward and southwestward from this landmass in late Madera time. It seems reasonable that the eastern part of the basin west of the Sierra Grande arch would have intercepted most of the clastic material derived from this arch. FIG. 7...
