|The Cannington silver-lead-zinc deposit is located at latitude 21¦ 52' 9" South, longitude 140¦ 55' 10"" East, on the south-eastern margin of the Proterozoic Mount Isa Block (Figure 1), 135 kilometres south-east of Cloncurry. Access is via a graded shire road for 80 kilometres south from the small pastoral community of McKinlay.REGIONALThe deposit is hosted by the Proterozoic Soldiers Cap Group within the Mount Isa Block Eastern Succession. South of the Cloncurry Beardsmore et al (1988) have grouped part of the Eastern Succession stratigraphy intothe Fullarton River and Soldiers Cap groups (1760-1740 million years) which together make up the Maronan Super Group. This is an apparently conformable sequence 10 kilometres thick and consists of metamorphosed sediments and volcanics with intrusive amphibolite bodies.The Maronan Super Group has experienced a complex history of deformation with up to six events having been recognized. The stratigraphy trends broadly north-south and is predominantly characterized by tight, upright isoclinal fold structures.|
