Internal structure of the Paleoarchean Mt Edgar dome, Pilbara Craton, Western Australia

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...

Paleomagnetism 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...

Seismic structure of the Yilgarn Craton, Western Australia

The deep crustal and upper mantle structure of the Yilgarn Craton is investigated in this study using receiver-function analysis of teleseismic earthquake records from temporary stations. Two lines of stations were deployed, the main transect ran between Perth and Kalgoorlie, and a second line of stations ran across the east Yilgarn Craton 200 km to the north of Kalgoorlie. The broadband instru...
