System leadership through extended headship roles: research associate, full report

Succession planning and the development of system leadership are ‘hot topics’ in education at the start of the 21st century. The widely held concern that we might be about to encounter a loss of ‘baby boomer’ headteachers leaving gaps that would prove difficult to fill has exercised the country’s educationalists for the past decade. At the same time the rapid development of system leadership – experienced headteachers undertaking significant outreach work and often supporting schools who are struggling to raise standards – has become a feature of the educational landscape. This report explores whether one might support the other, namely, whether development of system leadership might also encourage the development of tomorrow’s leaders

Scientists and explorationists have sought the next giant IOCG deposit since the discovery of Olympic Dam. Exploration has been hampered by a lack of clarity in modelling and classification of IOCG deposits. This study aims to determine the source of mineralisation in both economic and subeconomi IOCG mineralised systems from the Mt Woods Inlier, Gawler Craton, South Australia. Magnetite separates and whole rock samples were subjected to Nd isotopic analysis, REE and trace element distribution, XRF and petrographic analysis. Petrographic analysis of samples suggests three generations of magnetite; primary/magmatic, massive vein, and disseminated metasomatic magnetite. LREE enrichment is ubiquitous amongst a mixture of single-fluid and multi-fluid systems. Ore samples from Prominent Hill show no evidence of multiple phases of fluid alteration based on REE or isotopic data. Additionally, primitive εNd values in ore samples suggest derivation from a single generation of fluid sourced from a mantle reservoir. The Taurus prospect harbours similar signatures. The results presented here are contrary to previous IOCG mineralisation models, thus are significant for explorationists and researchers.Mode of access: World wide web1 online resource (xii, 58 pages) colour illustrations, map
