| Summary: | and localized in a narrow zone. Neighboring fault segments antithetic small faults also occurs near these geometric appears to be more common where the adjacent fault segment as well as the magnitude of overlap. With increasing comprise a small-scale graben accommodating NW-SE extension. consists of multiple fault segments arranged as "en echelon" curving to abut the other or the two segments are linked in displacement, fault structure becomes more complex. A fault earlier formed segments. As in the earlier stage, systems of exhibits a nonplanar local geometry. Enhanced development of faulting was between 100 and 900 m. faults. Wall rock deformation adjacent a fault occurs but is for this difference is unresolved. Cataclasis within the form between and abut the earlier formed larger fault Gause, Milam County, Texas. The faults strike NE-SW and in direct association with the larger faults except for a interbedded siltstones and shales. Five faults and fault irregularities. Clay smears develop along fault segments larger faults. In the initial stages of development, a fault limited grain breakage together with rigid body grain lithified quartz sandstones with several horizons with m to between 6-15 m. Smaller displacement faults occur only observed and are related to sense of fault stepover and shear of a limited nature. Locally, drag folding occurs, but this quarry in the Eocene Carrizo Formation near the town of rotation. The limited grain breakage together with other sandstone and clay in another subunit (unit B). The cause secondary faults form in the overlap regions of larger sedimentological data suggest the depth of burial during segments. Three different systems of secondary faults are series of excellently exposed, normal faults in a small shear zones of faults in the sandstone consists of some smears do not develop along faults that offset interbedded system of small faults that forms locally between two of the The Carrizo Fm. consists primarily of friable to weakly the overlapping region by a system of secondary faults that the subunits (unit A) of the Carrizo. In contrast, clay This study characterizes the structure and evolution of a usually overlap and link either directly by one segment where they offset interbedded sandstone and clay of one of zone evolves as more fault segments develop in proximity to zones occur in the quarry with displacements ranging from 0.3 |
