A review of the metallogeny and tectonics of the Lachlan Orogen

Magnetotelluric survey for undercover structural mapping, Central Victoria

“…In particular, the Bendigo Zone has been identified as the most richly endowed metallogenic belt in the Victorian gold province (Lisitsin et al 2007) making up most of the 2% of total world production coming from the state (Phillips & Hughes 1996). However, as most of the shallow ore deposits have now been discovered (Hough et al 2007), there is considerable incentive to develop and use new methods to detect buried mineralisation zones, particularly to the north of the current major gold regions, where the geological structure is obscured by sedimentary deposits from the Murray Basin (Smith & Frankcombe 2006).…”

Saqez–Sardasht Goldfield, North Sanandaj‐Sirjan Zone, Iran: A Tectono‐Metallogenic Synthesis

“…The first recorded gold occurrences within the SSZ metallogenic belt contained the Muteh and Zartorosht goldfields at the central and southern provinces, respectively (Aliyari et al, 2012); nonetheless, the Northern SSZ has been potentially considered as a goldbearing zone only during the recent two decades, especially with regard to orogenic gold deposits. Zagros orogenic gold typology is rather comparable to some other Gondwanan Phanerozoic subduction systems, e.g., New Zealand, South American (Bierlein et al, 2001;Goldfarb et al, 2001) and Lachlan orogenies (Hough et al, 2007). Orogenic/metamorphic golds have been generally associated with "ophiolitic and greenschist basement of Late Proterozoic-Early Cambrian" age by Ghorbani (2013) as well as being ascribed to the "greenstone-hosted Fig.…”

Geological Survey of New South Wales: New AusLAMP 3D conductivity model supports tectonic interpretation in New South Wales

“…There is extensive evidence of the geological evolution the state, however most data are collected from outcropping rocks or those near surface (Glen 2005;Gray et al 2006;Spampinato et al 2015). Currently, almost all of the known metal resources and occurrences in NSW occur in areas of outcropping or sub-cropping geology (Hough, Bierlein, and Wilde 2007). This reliance on surface and near-surface data places a significant limitation on the understanding of the state's geology as well as the ability of explorers to find new resources.…”
