Structural Controls on gold mineralization on the margin of the Yilgarn craton, Albany–Fraser orogen: The Tropicana Deposit, Western Australia
25 26 The Tropicana gold deposit is located adjacent to the margin of the Yilgarn craton in 27 the Albany–Fraser orogen, Western Australia. The deposit is hosted in granulite facies 28 quartzo-feldspathic gneisses of the Archean Tropicana Gneiss. Ore bodies comprise 29 biotite-pyrite alteration concentrated in shear zones that formed during NE-SW 30 shortening in the late Archean, and clearly p...
متن کاملGeochronological constraints for a two-stage history of the Albany–Fraser Orogen, Western Australia
Based on structural, petrographic and geochronological work (SHRIMP zircon, monazite and rutile), the Mesoproterozoic Albany–Fraser Orogeny is divided into two discrete thermo-tectonic stages, between c. 1345 and 1260 Ma (Stage I) and c. 1214 and 1140 Ma (Stage II). The existence of a two-stage history is confirmed by the discovery of 1321924 Ma detrital zircons and 1154915 Ma metamorphic rutil...
متن کاملPossible Basement Transverse Faults in the Western Alborz, Northern Iran
Transverse basement (TB) faults are important structures in the mountain belts or sedimentary basins influencing various aspects of them. The origin of these faults is diverse, but their effect on the shape and configuration of continental margins is characteristics. The Western Alborz range that borders the South Caspian basin to southwest is a complex range with principal faults and known ear...
متن کاملLithospheric structure of the Pilbara Craton, Capricorn Orogen and northern Yilgarn Craton, Western Australia, from teleseismic receiver functions
The upper lithospheric structure from the Pilbara Craton, across the Capricorn Orogen, to the northern Yilgarn Craton is determined from high-fidelity broadband seismic data. Three-component temporary stations were deployed in a line running southwards from Marble Bar, Western Australia, at approximately 118 E longitude. They were in position between July and October 2000. Receiver functions ar...
متن کاملWestern Australia , Perth , WA , Australia
We have recently suggested that numerosity is a primary sensory attribute, and shown that it is strongly susceptible to adaptation. Here we use the Method of Single Stimuli to show that observers can extract a running average of numerosity of a succession of stimuli to use as a standard of comparison for subsequent stimuli. On separate sessions observers judged whether the perceived numerosity ...
