“…1) forms the southwestern boundary of the Death Valley extensional sub-province, southeastern California (Wright & Troxel 1970;Wright 1976;Butler et al 1988). This fault zone consists of a number of NW-SE-striking segments that can be divided into two sub-zones: an eastern sub-zone and a western sub-zone (Fig. lc) (Butler et al 1988). Recent fault activity (1 Ma-Present) has been recorded (Butler et al 1988; this study) on the highly segmented eastern sub-zone in Plio-Pleistocene fluviolacustrine sediments.…”

The Confidence Hills form a well exposed, composite, positive flower structure developed in Pliocene to Recent lacustrine and alluvial fan sediments. The structure has developed along the current trace of the southern Death Valley dextral strike-slip fault zone. California, USA. NW-SEstriking fault zones bound the Confidence Hills. In 3D, these fault segments are inferred to link at depth to a common basal fault system. The flower structure is formed by doubly plunging anticlines that roughly parallel the bounding fault segments. Fold development was aided by: (a) the presence of a basal salt deposit and numerous detachment horizons within the sedimentary pile and (b) buttressing and uplift along and against the bounding oblique-slip reverse faults. Structural and palaeomagnetic evidence indicates that the anticlines developed with axial surfaces parallel and sub-parallel to the trace of both fault zones. Folding appears to have initially developed adjacent to and above the southeastern fault segment and then propagated outwards and to the northwest. The latest displacements along the current southern Death Valley fault zone are probably only in the orders of hundreds of metres and as young as 0.9 Ma to Recent. This young fault zone is highly segmented along the length of the floor of southern Death Valley: the high proportion of oblique-slip faulting consistent with the strike-slip zone being immature. The Confidence Hills structure displays close geometric similarities with other natural examples of positive flower structures and to the features found in scaled. analogue sandbox experiments of strike-slip faulting.

“…All of the lateral displacement along the western side of the southern Death Valley fault zone probably took place between about mid-Miocene time and 1 Ma (Butler et al, 1988). Activity then shifted to an eastern strand of the fault zone, which has experienced relatively little offset (Butler et al, 1988;T. Dooley and K. McClay, written communication, 1991).…”

“…Offset of Quaternary gravels along the fault system led Butler (1984) to conclude that there has been between 20 and 35 km of offset on the southern Death Valley fault zone. All of the lateral displacement along the western side of the southern Death Valley fault zone probably took place between about mid-Miocene time and 1 Ma (Butler et al, 1988). Activity then shifted to an eastern strand of the fault zone, which has experienced relatively little offset (Butler et al, 1988;T.…”

Pliocene to Recent lacustrine and playa deposits in the southwestern UnitedStates preserve a sedimentary record of climate change and tectonic activity. The middle Pliocene record is particularly important, because it represents the beginning of the glacial-interglacial climate that characterizes the Quaternary. However, continental sedimentary records of this time period are scarce. Well-exposed playa margin deposits in the Confidence Hills, southern Death Valley National Monument, California, were deposited between about 2.5 and 1.5 Ma. Detailed chronometric control is provided by tephrochronology and magnetostratigraphy.A new stratigraphic unit, the Confidence Hills Formation, is herein defined. This formation consists of interbedded fine-to coarse-grained siliciclastic strata with abundant gypsum and anhydrite. Ten distinct sedimentary lithofacies were defined within the Confidence Hills Formation based on variations in their siliciclastic and evaporite components. Lithofacies dominated by siliciclastic components include the siltstone, fine-grained sandstone, coarse-grained sandstone, and interbedded coarse-grained sandstone/conglomerate lithofacies. Those dominated by evaporitic components include the halitic mudstone/siltstone/fine-grained sandstone, gypsiferous mudstone/siltstone/fine-grained sandstone, banded anhydrite, and thin-bedded to massive anhydrite lithofacies. The siliciclastic component shows an overall coarsening-and thickening-upward trend, from dominantly thinly bedded siltstone in the lower part of the section to dominantly medium-bedded, fine-to medium-grained sandstone in the upper part. Superimposed on this pattern is variation in amounts, types, and textures of evaporite deposits.The lithofacies observed in the Confidence Hills are readily interpretable using the classification of saline lake subenvironments developed by Hardie et al. (1978). The halitic mudstone lithofacies is interpreted as having been deposited within the center of the saline lake. The anhydrite-and gypsum-bearing lithofacies are interpreted as having been deposited in the saline mudflat subenvironment marginal to the saline lake. The siliciclastic sediment was derived primarily from the Owlshead Mountains to the west and deposited by streamflood mechanisms in a distal alluvial fan setting.The overall coarsening-upward sequence is interpreted as recording progradation of one or more marginal alluvial fans into a saline lake. The depositional rate was fairly constant at about 29 mm/ka. Major changes in depositional setting occurred
