Lithospheric 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 کاملUpper crust of the Pilbara Craton, Australia; 3D geometry of a granite/greenstone terrain
The Pilbara Craton in Northwest Australia is a 600×550 km region of early-mid Archaean granite/greenstone terrain, dominated by granite domes, and in part covered by younger rocks. Gravity and magnetic anomalies are used to map the granite/greenstone surface under cover, and infer the depth extent of the granite/greenstone structures. A published seismic refraction interpretation gives a two la...
متن کاملPaleomagnetism of Mafic Dikes in the Northern Pilbara Craton, Western Australia
Two well preserved Archean cratons, Kaapvaal and Pilbara, have remarkably similar geological successions during the Archean and Paleoproterozoic. This has led some to propose that the two may have been connected during that interval, thus experiencing similar tectonic events. We sampled Archean and Proterozoic rocks from the Pilbara craton in order to test the Vaalbara hypothesis, especially th...

متن کاملOrigin and evolution of a submarine large igneous province: the Kerguelen Plateau and Broken Ridge, southern Indian Ocean
Oceanic plateaus form by mantle processes distinct from those forming oceanic crust at divergent plate boundaries. Eleven drillsites into igneous basement of Kerguelen Plateau and Broken Ridge, including seven from the recent Ocean Drilling Program Leg 183 (1998^99) and four from Legs 119 and 120 (1987^88), show that the dominant rocks are basalts with geochemical characteristics distinct from ...
