The document discusses lead deposits in India. It notes that 85% of India's lead deposits are located in Rajasthan, with major deposits found in Rampura-Agucha, Rajpura-Dariba, and Sindesar. It also lists lead deposits and occurrences in other states such as Andhra Pradesh, Jharkhand, Madhya Pradesh, Karnataka, Odisha, Gujarat, and West Bengal. The chief ores of lead discussed are galena, cerussite, and anglesite. Current uses of lead mentioned include lead-acid batteries, stained glass production, and fishing sinkers.

Lead(Pb) occurs in native state, but it is quite rare.
The metal is bluish grey in colour & shows on its fresh
surface a bright metallic lustre which quickly oxidises
on exposure to air.

19. DISTRIBUTION OF LEAD IN
INDIA

20. 85% of the lead deposits if India
occur in Rajasthan.
The important lead deposits of India
include Rampura-Agucha
(Bhilwara district), Rajpura-Dariba
and Sindesar (Rajsamand district),
Zawar (Udaipur), Sawar
and Kayar-Ghugra (Ajmer district),
Basantgarh and Deri (Sirohi district)
in Rajasthan;
Mineralisation occurs along several
belts in rocks of
the Aravalli and Delhi Supergroups
and in
pre-Aravalli rocks.

23. ANDHRA PRADESH
Galena occurs at Chityala and
Chelima in Kurnool district,
Karempudi in Guntur district and
Zangamrajupalle in Cuddapah
district. Galena is also reported to
occur near Chintakunta in
Nalgonda district and Jestaipalli
in Khamam district.
These deposits and occurrences
are mostly hosted in rocks of the
Cuddapah Supergroup and to a
lesser extent in rocks of the
Kurnool Group, Pakhal
supergroup

24. JHARKHAND
Occurrences of argentiferous
lead ore had been located in
Hazaribagh district. Galena is
found in parts of Singhbhum,
Ranchi, Hazaribagh and Palamau
districts but with little chance of
success in their working. The GSI
has taken up investigation in
some parts of the State

25. MADHYA PRADESH
Lead-ores, often argentiferous, are
on a fairly large scale. Mahanadi
River near Padampur, Bilaspur
district. Occurrences have been
reported at Ranitalao near Chicholi,
Thelkadand Karamatara in Durg
district, Bhelaunda and Chiraikhurd
in Sarguja district, Andar in Shivpuri
district and near Kurol in Gwalior
district.
In Madhya Pradesh, basemetal
deposits and occurrences have been
recorded from Malanjkhand
granitoid belt, Bhundelkhand granite
complex and the Mahakhosal and
Vindhyan Groups of rocks.

26. KARNATAKA
Lumps of galena were found at
Metri, 40 kms north-west of
Bellary during 1951-52; but
detailed prospecting by drilling and
pitting has shown that the deposits
are not of economic importance.
Some minor occurrences of lead-
ore are known near Ingaldhal in
Chitradurga district.
These deposits and occurrences are
mostly hosted in rocks of the
Dharwar supergroup.

27. ODISHA
The lead-ore deposits were
located along a 35 km belt of the
Sargipalli in Sundargarh,
Kesarpur in Mayurbhanj
district,Karmali in Sambalpur.
During the year 1986 the
district of Sundargarh produced
5,451 tonnes of lead
concentrate.
Lead mineralization forms part
of the southern extension of the
Singhbhum Copper belt of
Jharkhand.

28. GUJARAT
Lead ores are found in
Ambamata-Chitrasani
in Banasakantha
District , Khandia in
Vadodara district

29. WEST BENGAL
Small pockets of argentiferous galena,
cerussite and sphalerite occur in the
dolomite bands in Buxa Duars area of
Jalpaiguri district. Lead-ores occur also
in a number of other places in Darjeeling
and western Duars area. In the district of
Darjeeling 2.27 million tonnes of
probably recoverable reserves have been
estimated in which each of the lead and
zinc metals, are estimated at 56 thousand
tonnes.
Lead-zinc deposit occurs in the Daling
Group (Precambrian to early Cambrian
age) which consists mainly grey green or
green chlorite-quartz-sericite
schist/phyllite, sericite-chlorite quartzite,
quartzmagnetite
rock, mylonites, epidiorites, etc.
