Stratigraphic Dating of Fault Systems
Several northeast-trending transverse faults cut the Purcell succession and parts of the Lower Paleozoic succession in the Hughes Range. Relationships along unconfonnities within and at the base of the Lower Paleozoic strata provide evidence of the natilre and timing of displacement on these faults. Field mapping of the faults and unconformities hounding three Lower Paleozoic formntions have be...
متن کاملK-Ar and Ar-Ar Dating
The aim of this chapter is to present the K-Ar and Ar-Ar dating techniques in the context of noble gas studies, since there are already several recent texts on K-Ar and ArAr dating (Dickin 1995; McDougall and Harrison 1999). The focus of this section will be aspects of argon transport and storage in the crust, which affect K-Ar and Ar-Ar dating including Ar-loss from minerals by diffusion and A...
متن کاملDo Radioisotope Clocks Need Repair? Testing the Assumptions of Isochron Dating Using K-Ar, Rb-Sr, Sm-Nd, and Pb-Pb Isotopes
The assumptions of conventional whole-rock and mineral isochron radioisotope dating were tested using a suite of radioisotopes from two Precambrian rocks. Amphibolite from the Beartooth Mountains of Wyoming shows evidence of thorough metamorphism by isochemical processes from andesite by an early Precambrian magma-intrusion event. A diabase sill, exposed within the wall of Grand Canyon at Bass ...
متن کاملU-Th dating of carbonate platform and slope sediments
—Absolute chronology of marine sediment beyond the C age range provides a test for models of climate change and has many other applications. U-Th techniques have been used for such chronology by dating corals, but extending these techniques to marine sediment is complicated by the presence of significant initial Th—both in detrital material and scavenged from seawater. In this study, we investi...
متن کاملMonitoring and fault-diagnosis with digital clocks
We study the monitoring and fault-diagnosis problems for dense-time real-time systems, where observers (monitors and diagnosers) have access to digital rather than analog clocks. Analog clocks are infinitely-precise, thus, not implementable. We show how, given a specification modeled as a timed automaton and a timed automaton model of the digital clock, a sound and optimal (i.e., as precise as ...
