Geographical Localization
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.
Region
is similar to province but relatively smaller in size, controlled by stratigraphy and/or structure, for occurrence of specific mineral(s)
at commercial quantity.
District
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.

Belt
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.
Deposit
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.
Block
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.
