INTRODUCTION
• A scrutiny of research work on
mineral prospecting in India
during the period from January
2004 to January 2007 reveals
that study of base-metals
received maximum attention.
• This was followed by gold-
diamond-bearing rocks
(kimberlite and lamproite), and
atomic minerals.
• Besides, prospecting of iron ore,
manganese, bauxite and
chromite received significant
attention.
• Increasing demand in the power
sector has witnessed a thrust on
prospecting for coal and lignite.
• Besides geological prospecting,
geophysical prospecting
employing different
methodologies have also
received attention.
1. BASE METALS
• A few old workings besides profuse malachite
encrustation, bornite, covellite and chalcopyrite are the
main surface manifestations of mineralisation in
RAJASTHAN.
• Mainly metasoda rhyolite, garnet mica schist and
metavolcanics host mineralisation in Bhagal block.
• The copper mineralisation is, by and large, controlled by
the structural elements.
• Chalcopyrite is main copper ore mineral in the area. The
other ore minerals are pyrrhotite, pyrite and magnetite
in the decreasing order of abundance.
• Ilmenite, Haematite, Graphite and Sphene are present as
minor minerals whereas Limonite/goethite, Sphalerite,
Pentlandite, Machinawite and Tennantite occur as
accessory minerals.
• Mineralisation occurs as veins, veinlets, stringers, fracture
fillings, patches and disseminations.
…COPPER
…LEAD-ZINC DEPOSITS
• Most of these deposits are Carbonate
hosted Lead-Zinc Ore deposits.
• Source: host carbonate sequence
where diagenetic recrystallisation
occurs
• The trapped deposits are formed by
replacement processes in the
presence of trapped hydrocarbons.
• Sulfide minerals such as Galena,
Sphalerite, Marcasite and Pyrite thus
form.
• Often the prospectivity of particular
carbonate formations for lead-zinc
deposits of this nature is first
identified by core drilling by oil
explorers.
2. GOLD
•Greenstone belts
•Geology, structure & mineralization comparable
to SA
•Preferentially concentrated in vein quartz, often
associated with sulphides
• These gold prospects represent typical Archean
hydrothermal lode gold mineralisation.
• Some deposits are hosted within sulphic banded
iron formation. Ex.: Mallapokanda deposits (South
Kolar)
•Mineralisation is hosted by hornblende schist in
the western part of the schist belt
•Whereas in the eastern part mineralisation occurs
in the felsic volcanic of the Champion Gneiss.
•Mineralisation is controlled by shear zones
Gold mines of Chittoor
are closed as they are
not economically
viable
•Recently, there has been a gold rush in
Eastern Singhbhum.
•Gold deposits here, occur along the shear
zone with Uranium and copper deposits.
GOLD…
3. DIAMOND
•Thrust for diamond prospecting was noticed
in Andhra Pradesh, Chhattisgarh, Madhya
Pradesh, Karnataka andOrissa.
•New kimberlite/lamproite fields have been
located in Andhra Pradesh and Karnataka. A
few lamproite bodies have also been reported
from Orissa.
•Investigations forkimberlite/lamproite was
carried out in the Krishna River Basin.
•Discovery of three kimberlite pipes from the
Basin in Gadwal area, Mahboobnagar district,
Andhra Pradesh came into light in 2004.
4. FERROUS GROUP
…IRON ORE DEPOSITS
The iron ore deposits of India can be broadly
divided in to the following six groups on the
basis of mode of occurrence and origin:
1. Banded Iron Formations (BIF) of Pre-Cambrian
Age
2. Sedimentary Iron Ore Deposits of Siderite and
Limonitic Composition
3. Lateritic Ores derived from the Sub-Aerial
Alternations
4. Apatite-Magnetite Rocks of Singhbhum
Copper belt (Very rare – Pathargora)
5. Titanifereous and Vanadiferous Magnetites
6. Fault and Fissure Filling Deposits
Locations:
1.Rich Iron Ore group: Noamundi (W.
Singhbhum) – Singhbhum, Keonjhar
2.Western Dharwar Craton (along with
some Mn) – Bellary & Goa
…CHROMITE DEPOSITS
1. Sukinda
2. Nushai
3. Jojohatu
4. Kimsiburu
Formed in
Ultra-basic
rocks
Magmatic
layering
due to
segregation
…MANGANESE
• Important Manganese deposits are found in Bonai-Kendujhar belt and Eastern Ghat,
Granulite belt in Orissa.
• In the Eastern Ghat Granulite belt, discontinuous manganese mineralization was associated
with khondalite group of rocks.
• Manganiferous horizon with syn-genetic manganese ore from the granulite belt was also
reported.
• The manganese ore occurrences of Eastern Ghat are of syn-genetic type.
• These were later remobilized in different phases of structural deformation by meteoric water
along the weak planes of associated host rocks to form the secondary minerals.
• In Bonai- Kendujhar belt, the mineralization is associated with a low grade volcanic
sedimentary sequence, belonging to the Koira Group of Iron Ore Supergroup.
• A formational status was proposed to the manganiferous horizon in Bonai-Kendujhar belt.
5. URANIUM
Majority of these resources occur in following 3 uranium
provinces.
(i) Singhbhum uranium province, located in the Eastern Region.
All the deposits, presently being exploited, such as Jaduguda,
Narwapahar, Turamdih, and Bagjata occur in this province. The
other deposits in this belt are Mohuldih, Nandup, Rajgaon,
andGaradih . All these occurrences are of vein type.
(ii) Mahadek uranium province, located in the
Northeastern Region. The Cretaceous Mahadek Formation in
Meghalaya contains the largest and richest sandstone-hosted
uranium deposit of the country at Domiasiat (KPM deposit) in
West Khasi Hills district. Another deposit of similar nature is
at Wahkyn where exploration activities are in progress.
India's identified conventional uranium resources (RAR and Inferred) are estimated to amount to 105 900 tU
and are hosted by the following type of deposits
URANIUM…
iii) Cuddapah uranium
province, located in the
Southern and South Central
Regions. It contains the
Proterozoic unconformity
related uranium deposit
at Lambapur-Peddagattu in
Nalgonda district, Andhra
Pradesh. The Cuddapah
basin also hosts a unique
stratabound uranium deposit
associated with siliceous
dolostone at Tummalapalle in
Cuddapah district, Andhra
Pradesh.
6. MOLYBDENUM & TUNGSTEN
• The tungsten mineralization occurs at
Balda, Rajasthan.
• The Balda granite is spatially associated
with mineralization that owes its genesis
to the associated magmatic
hydrothermal system.
• The wolframite mineralization is
confined to quartz veins and greisenized
pegmatites located along the shear zones
in Balda granite.
7. COAL
1. The chief source of commercial energy
in the country.
2. Economically exploitable Indian coals
are broadly
3. restricted to two geological times —
Permian Gondwanas and Tertiaries.
4. More than 99% of the known geological
resources are contained in the
Gondwanas of well-defined
5. belts of Damodar-Koel, Son-Mahanadi,
Narmada (Satpura), Pranhita-Godavari
valleys and Rajmahal basin.
6. Economic deposits of Tertiary coal
occur mainly in the northeastern India
and a few small deposits along Jammu
foothills.
7. The spread of Gondwanas has also been
reported from beneath the Bengal
Basin, eastern India and the Deccan
Traps in central India.
SUMMARY

Economic mineral deposits india

  • 1. Mineral Prospecting & Deposits in India - An Overview AKHIL PRABHAKAR 3rd Year, Intg. M.Tech Geophysical Technology 09411004
  • 2. INTRODUCTION • A scrutiny of research work on mineral prospecting in India during the period from January 2004 to January 2007 reveals that study of base-metals received maximum attention. • This was followed by gold- diamond-bearing rocks (kimberlite and lamproite), and atomic minerals. • Besides, prospecting of iron ore, manganese, bauxite and chromite received significant attention. • Increasing demand in the power sector has witnessed a thrust on prospecting for coal and lignite. • Besides geological prospecting, geophysical prospecting employing different methodologies have also received attention.
  • 3. 1. BASE METALS • A few old workings besides profuse malachite encrustation, bornite, covellite and chalcopyrite are the main surface manifestations of mineralisation in RAJASTHAN. • Mainly metasoda rhyolite, garnet mica schist and metavolcanics host mineralisation in Bhagal block. • The copper mineralisation is, by and large, controlled by the structural elements. • Chalcopyrite is main copper ore mineral in the area. The other ore minerals are pyrrhotite, pyrite and magnetite in the decreasing order of abundance. • Ilmenite, Haematite, Graphite and Sphene are present as minor minerals whereas Limonite/goethite, Sphalerite, Pentlandite, Machinawite and Tennantite occur as accessory minerals. • Mineralisation occurs as veins, veinlets, stringers, fracture fillings, patches and disseminations.
  • 5. …LEAD-ZINC DEPOSITS • Most of these deposits are Carbonate hosted Lead-Zinc Ore deposits. • Source: host carbonate sequence where diagenetic recrystallisation occurs • The trapped deposits are formed by replacement processes in the presence of trapped hydrocarbons. • Sulfide minerals such as Galena, Sphalerite, Marcasite and Pyrite thus form. • Often the prospectivity of particular carbonate formations for lead-zinc deposits of this nature is first identified by core drilling by oil explorers.
  • 6. 2. GOLD •Greenstone belts •Geology, structure & mineralization comparable to SA •Preferentially concentrated in vein quartz, often associated with sulphides • These gold prospects represent typical Archean hydrothermal lode gold mineralisation. • Some deposits are hosted within sulphic banded iron formation. Ex.: Mallapokanda deposits (South Kolar) •Mineralisation is hosted by hornblende schist in the western part of the schist belt •Whereas in the eastern part mineralisation occurs in the felsic volcanic of the Champion Gneiss. •Mineralisation is controlled by shear zones Gold mines of Chittoor are closed as they are not economically viable •Recently, there has been a gold rush in Eastern Singhbhum. •Gold deposits here, occur along the shear zone with Uranium and copper deposits.
  • 8. 3. DIAMOND •Thrust for diamond prospecting was noticed in Andhra Pradesh, Chhattisgarh, Madhya Pradesh, Karnataka andOrissa. •New kimberlite/lamproite fields have been located in Andhra Pradesh and Karnataka. A few lamproite bodies have also been reported from Orissa. •Investigations forkimberlite/lamproite was carried out in the Krishna River Basin. •Discovery of three kimberlite pipes from the Basin in Gadwal area, Mahboobnagar district, Andhra Pradesh came into light in 2004.
  • 10. …IRON ORE DEPOSITS The iron ore deposits of India can be broadly divided in to the following six groups on the basis of mode of occurrence and origin: 1. Banded Iron Formations (BIF) of Pre-Cambrian Age 2. Sedimentary Iron Ore Deposits of Siderite and Limonitic Composition 3. Lateritic Ores derived from the Sub-Aerial Alternations 4. Apatite-Magnetite Rocks of Singhbhum Copper belt (Very rare – Pathargora) 5. Titanifereous and Vanadiferous Magnetites 6. Fault and Fissure Filling Deposits Locations: 1.Rich Iron Ore group: Noamundi (W. Singhbhum) – Singhbhum, Keonjhar 2.Western Dharwar Craton (along with some Mn) – Bellary & Goa
  • 11. …CHROMITE DEPOSITS 1. Sukinda 2. Nushai 3. Jojohatu 4. Kimsiburu Formed in Ultra-basic rocks Magmatic layering due to segregation
  • 12. …MANGANESE • Important Manganese deposits are found in Bonai-Kendujhar belt and Eastern Ghat, Granulite belt in Orissa. • In the Eastern Ghat Granulite belt, discontinuous manganese mineralization was associated with khondalite group of rocks. • Manganiferous horizon with syn-genetic manganese ore from the granulite belt was also reported. • The manganese ore occurrences of Eastern Ghat are of syn-genetic type. • These were later remobilized in different phases of structural deformation by meteoric water along the weak planes of associated host rocks to form the secondary minerals. • In Bonai- Kendujhar belt, the mineralization is associated with a low grade volcanic sedimentary sequence, belonging to the Koira Group of Iron Ore Supergroup. • A formational status was proposed to the manganiferous horizon in Bonai-Kendujhar belt.
  • 13. 5. URANIUM Majority of these resources occur in following 3 uranium provinces. (i) Singhbhum uranium province, located in the Eastern Region. All the deposits, presently being exploited, such as Jaduguda, Narwapahar, Turamdih, and Bagjata occur in this province. The other deposits in this belt are Mohuldih, Nandup, Rajgaon, andGaradih . All these occurrences are of vein type. (ii) Mahadek uranium province, located in the Northeastern Region. The Cretaceous Mahadek Formation in Meghalaya contains the largest and richest sandstone-hosted uranium deposit of the country at Domiasiat (KPM deposit) in West Khasi Hills district. Another deposit of similar nature is at Wahkyn where exploration activities are in progress. India's identified conventional uranium resources (RAR and Inferred) are estimated to amount to 105 900 tU and are hosted by the following type of deposits
  • 14. URANIUM… iii) Cuddapah uranium province, located in the Southern and South Central Regions. It contains the Proterozoic unconformity related uranium deposit at Lambapur-Peddagattu in Nalgonda district, Andhra Pradesh. The Cuddapah basin also hosts a unique stratabound uranium deposit associated with siliceous dolostone at Tummalapalle in Cuddapah district, Andhra Pradesh.
  • 15. 6. MOLYBDENUM & TUNGSTEN • The tungsten mineralization occurs at Balda, Rajasthan. • The Balda granite is spatially associated with mineralization that owes its genesis to the associated magmatic hydrothermal system. • The wolframite mineralization is confined to quartz veins and greisenized pegmatites located along the shear zones in Balda granite.
  • 16. 7. COAL 1. The chief source of commercial energy in the country. 2. Economically exploitable Indian coals are broadly 3. restricted to two geological times — Permian Gondwanas and Tertiaries. 4. More than 99% of the known geological resources are contained in the Gondwanas of well-defined 5. belts of Damodar-Koel, Son-Mahanadi, Narmada (Satpura), Pranhita-Godavari valleys and Rajmahal basin. 6. Economic deposits of Tertiary coal occur mainly in the northeastern India and a few small deposits along Jammu foothills. 7. The spread of Gondwanas has also been reported from beneath the Bengal Basin, eastern India and the Deccan Traps in central India.
