...-Mesoproterozoic sedimentary sequences, felsic plutonic rocks and bimodal volcanics. The inlier records a complex and protracted history of magmatic and orogenic activity extending throughout an interval of more than 300 Ma ( Fig. 2 ). The Inlier can be divided into three main tectonic domains: the Western Fold...

... ) and the uranium-enriched (8–14 ppm U), high radiogenic heat-producing Sybella Granite ( McLaren et al. 1999 ). Conversely, IOCG systems within intermediate to mafic calc-alkaline volcanic sequences, such as the subduction-related deposits of the Peruvian and Chilean coastal belt, would be expected to have low...

..., supplemented by available geological evidence. The Yilgarn craton in Western Australia (Figure 1 ) consists of several geological provinces. Gneissic granitoid with granitoid plutons and greenstone supracrustal rocks are common in all provinces. Each province can be divided into a number of terranes...

.... Former studies in the Cloncurry District suggest that albitization of the country rocks was caused by fluids released from crystallizing plutons ( Mark 1998 a ; Mark & Foster 2000 ). Contrary to this, De Jong & Williams (1995) discuss an external origin of the fluids responsible for the large...

... at this time as were several plutons within the Williams and Naraku batholiths ( Page and Sun, 1998 ; Perkins and Wyborn, 1998 ; Perkins et al., 1999 ). It is also consistent with the time of deposition of the lower parts of the Roper superbasin at 1492 ± 4 Ma ( Abbott and Sweet, 2000 ). Thus, the 1500 Ma...
