متن کاملStratigraphic and Structural Setting
mapping of a I5 square kilometre area around Jock Creek and detailed (1:lOOO) mapping of the mineralized area were carried out in 1988 and 1989. Marsden and Moore (1989) give an account of the geology outlined by mapping during the 1988 field season. This report presents some additions and revisions to that stratigraphy, integrates field observations with petrographic work and literature rese...
متن کاملChronostratigraphy of the CRP-3 Drillhole, Victoria Land Basin, Antarctica
An 823 m thick glaciomarine Cenozoic section sitting unconformably on the Lower Devonian Beacon Supergroup was recovered in CRP –3. This paper reviews the chronostratigraphical constraints for the Cenozoic section. Between 3 and 480.27 mbsf 23 unconformity bounded cycles of sediment were recorded. Each unconformity is thought to represent a hiatus of uncertain duration. Four magnetozones have b...
متن کاملMapping Stratigraphic Discontinuities in West Candor Layered Deposits and the Potential for Sequence Stratigraphic
Introduction: Other than the few Martian meteorites that have been found on Earth and the data being collected by the Mars Exploration Rovers, all data from Mars is remotely sensed which lends it to be developed and analyzed within a Geographic Information System (GIS) platform. This study is being accomplished by bringing together multiple datasets from the Mars Orbiter Camera (MOC), Mars Orbi...
متن کاملStratigraphic 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...
