Province or “Metallogenic Province”
is a large specific area having essentially notable concentration of several metal assemblages or a distinctive style of mineralization to be delineated and developed as economic deposits.
The metallogenic province can be formed on various processes such as plate tectonic activity, subduction, igneous intrusive, metal-rich epigenetic hydrothermal solution and expulsion of pore water enriched in metals from sedimentary basin.
The examples are Zn-Pb-Ag-bearing McArthur-Mount Isa inlier in Northern Territory, Australia, gold province in Canadian shield, Pt-Pd-Ni-Cu-Au deposits in Sudbury basin, Canada, Bushveld Igneous Complex with Pt-Pd-Cr deposits, South Africa, Katanga and Zambian copper province, tungsten province of China, Zn-Pb-Ag deposits of Aravalli Province and diamond bearing Kimberlite province of Wajrakarur-Narayanpet, India.
is similar to province but relatively smaller in size, controlled by stratigraphy and/or structure, for occurrence of specific mineral(s) at commercial quantity.
is comprised of one geographical area popularly known for occurrence of particular mineral.
The Examples Aeolian soils of Blayney District, NSW, Australia, Baguio mineral district in Philippines for copper deposits, New Mexico for uranium deposits, Singhbhum district for copper and Salem district for magnesite, India.
is a narrow linear stretch of land having series of deposits of associated minerals, such as, Colorado gold-molybdenum belt, US, Grant uranium mineral Belt, New Mexico Khetri copper belt, Rajpura-Dariba-Bethumni zinc-lead-silver belt, Rajasthan, Sukinda chromite belt, Orissa, India.
is comprised of a single or a group of mineral occurrences of sufficient size and grade separated by natural narrow barren parting.
Examples Broken Hill group of zinc-lead deposits, Australia, Zawar group of zinc-lead deposits, India, Red Dog zinc-lead deposit, Alaska, OK Tedi copper deposit, Papua New Guinea, Olympic Dam copper-gold-uranium-silver deposit, South Australia, Neves Corvo poly-metallic deposit, Portugal and Stillwater group of platinum deposit, US.
is a well-defined area having mineral concentration wholly or partly of economic value, such as Broken Hill main, Australia, Bailadila deposit-14, Central Mochia, India. The blocks in underground mining are subdivided to “Level” (say: upper level, lower level, 500-700 and 300-500 mRL). The levels are further split into “Stope” (say:West 301 stope, North 101 stope, Valley stope). These terms are locally convenient to use for attention and allocation of work activities in mineral exploration and sequencing mine production block.
