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...
متن کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels

15 صفحه اولLithospheric 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 کاملArchean gold mineralization synchronous with the final stages of cratonization, Yilgarn Craton, Western Australia
Sm-Nd ages of pegmatite dikes that crosscut gold-bearing structures in the southern Yilgarn Craton, Western Australia, provide minimum age constraints of 2640 6 11 Ma, 2628 6 10 Ma, and 2620 6 36 Ma for gold mineralization at the Westonia and Nevoria (Yellowdine Terrane) and Scotia (Norseman Terrane) gold deposits, respectively. Similarly, a post–gold mineralization dike at Westonia has a U-Pb ...
متن کاملYarrabubba, Western Australia: a Large, Deeply Eroded, Ancient Impact Structure in the Yilgarn Craton
Introduction: Shock-metamorphic effects including shatter cones, planar deformation features (PDFs) in quartz grains, and both E-and S-type pseu-dotachylites were discovered in deeply eroded Ar-chean granites near the Yarrabubba homestead in Western Australia (119°50'E, 27°10'S). Preliminary estimates indicate that the Yarrabubba impact structure is of a Paleoproterozoic age and at least 30 km ...
