Age of Barrier Canyon-style rock art constrained by cross-cutting relations and luminescence dating techniques.
Rock art compels interest from both researchers and a broader public, inspiring many hypotheses about its cultural origin and meaning, but it is notoriously difficult to date numerically. Barrier Canyon-style (BCS) pictographs of the Colorado Plateau are among the most debated examples; hypotheses about its age span the entire Holocene epoch and previous attempts at direct radiocarbon dating ha...
متن کاملThe Dating of Rock Art: a Critique
The methods for estimating the antiquity of rock art are reviewed critically, dividing them into traditional and scientific approaches. The reliability of both is examined critically. It seems that the most promising options have attracted only limited interest, while those methods that have been afforded the most sustained research efforts have been discredited or provide only tenuous results....
متن کاملStress wave attenuation in shock-damaged rock
The velocity and attenuation of ultrasonic stress waves in gabbroic rock samples (San Marcos, California) subjected to shock loading in the 2 GPa range were studied. From P wave velocity measurements we determined the damage parameter Dp and crack density e of the samples and related these to the attenuation coefficient (quality factor) under dynamic strains of 2 x 10 -? and at a frequency of 2...
متن کاملDating and context of rock engravings in southern Africa.
Rock art is seldom recovered from sealed archeological contexts and is therefore difficult to date or integrate with other artifactual assemblages. South African engravings, found on low rocks at open-air sites, exemplify the problem. Multiscale spatial study of technique, thematic variation, faunal content, geoarcheological paterning, settlement history, and ethno-archeological setting provide...
متن کاملA Review of Reservoir Rock Typing Methods in Carbonate Reservoirs: Relation between Geological, Seismic, and Reservoir Rock Types
Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through petrographic studies of the thin sections prepared from core plugs and cuttings. In the second step of rock typing study, electrofacies are deter...
