Granites of the eastern Hodgkinson Province their field and petrographic characteristics by Robert J. Bultitude, David C. Champion Pages, Published . , Granites of the Cape Melville 1: sheet area / R.J. Bultitude Dept. of Minerals and Energy, Queensland [Brisbane] Wikipedia Citation Please see Wikipedia's template documentation for further citation fields that may be required. Moderately to strongly fractionated S-type granites crop out extensively (> km2) in the central and eastern parts of the Hodgkinson Province, north Queensland, Australia.   In the eastern Hodgkinson Province km2 of Permian felsic 1- and S-type granites outcrop, of which the former comprise over 80%. The S-type granites comprise two major supersuites, the Cooktown and Whypalla Supersuites, and five minor by:

  In the central and eastern Hodgkinson Province S 1 is a slaty cleavage that generally lies subparallel or parallel to bedding, except in the hinges of rare, sporadically distributed D 1 folds. S 1 in local zones of low post-D 1 deformation intensity is commonly steeply dipping and trends north–south. The nomenclature of the Granite Provinces in SE Asia present in Thai land is based on that of Hutchison (); the granites of Thailand (Fig. ) are distributed in three Granite Provinces comprising a Western, Eastern and a Central Province that form approximately linear north-south belts. Granites in the eastern Hodgkinson Province have been recently dated as ca. Ma (Kositcin et al., a); their generation may also relate to, and date, the Tabberabberan deformation in. Granites of the high-HFSE, mafic and syenitic groups form a minor component (10–20%) of the Eastern Goldfields granites. The siliceous (74–77% SiO2) high-HFSE granites are restricted to a narrow NNW-trending zone and are characterised by high TiO2, total FeO, MgO, Y, Zr and Ce, but only moderate Rb, Th and Pb contents.

M. Lindsay's 3 research works with 24 citations and 64 reads, including: Deformation history and timing of granite emplacement in the Butchers Hill – Helenvale region, northern Hodgkinson. Exposed rocks of the Croydon Province are rhyolitic to dacitic ignimbrite, rhyolite and rare andesite of the Croydon Volcanic Group, granites of the Esmeralda Supersuite and shallow-water quartzose, mainly arenaceous sedimentary rocks of the Inorunie Group, which unconformably overlie the . granites sampled above the eastern Agwamin Seismic Province have much younger neodymium model ages, implying a significantly younger, possibly Grenville-age ( million years or Ma) component in the lower crust. • To the west of Croydon, a second major crustal boundary also dips west or southwest, offsetting the Moho and extending below it. parameter for north Queensland, only the western part of Hodgkinson Province and the eastern half of the Broken River Province (figure 3) emerge as prospective regions. Although these are sites of the major Palaeozoic basins in the region, it should be noted that one of the largest gold deposits in the region—Kidston—does.
