Marble is used as one of the building
stone in Rajasthan , which generates a lot of
industrial and mining activity in the state. The
Rajasthan state is largest producer of all kinds
of marble in the country Makrana (Nagaur
District) is known for a very fine quality of
white marble deposit. The other area where
marble is found are Udaipur, Sirohi, Pali,
Banswara, Dungarpur, Jaisalmer, Bundi
etc.
Occurrence And
Potentiality
Marble deposits of the
state can be broadly divided in four groups
(trade names).
- White Marble
- Pink Marble
- Green Marble
- Other Marble
White Marble
White marble is available
in Makrana ( District Nagaur ) in huge quantity,
which is often called Makrana stone in laymen
term. The marble deposit of Makrana is about 12
km. in length and 1.6 km. in length and 1.6 km.
in width. Well known deposits are found in
Kumari, Dungari, Bhermata Y Chancer area. The
deposit of Chancer area is considered to be the
finest one and quarri3es of this area have gone
upto a considerable depath of 15 to 60 meters.
Now a days, because of deep mining and other
factors, mining in Makrana area has become
uneconomical. Further, good quality material has
also been exhauseted. Hence the need for
developing new areas where marble is available,
close to surface was felt. Soon in Rajnagar
(Udaipur District) huge deposit of white marble
was discovered by the State Department of Mines
& Geology.
Although marble deposit in
Udaipur district are known since long back when
palaces and monuments in and around Udaipur were
built with local marble but in recent years this
district has received more attention and mining
activity in this district has developed rapidly.
In Udaipur district white marble is mainly
available in Rajnagar, Amet, Saprao, Marchana,
Agaria, Parvati etc.
Apart from Udaipur district
white marble in huge quantity is also available
in Tripura Sundri (District Banswara). This
marble is fine grained and has varities which
are pure white or that have pinkish or yellowish
shades. Some varities resemble to Italian
Marble.
Pink
Marble
Babarmal area of Udaipur
district is the only main producer of Pink
Marble in the state. The area is situated at 25
km South of Udaipur city on Jaisamand road. This
belt is about 5.20 km in length and 30 to 100
meters in width . This marble is some what hard,
hence require more time in cutting. Besides
this, small quantity of pinkish marble is also
found in Makrana and Abu Road area.
Green
Marble
Green marble is found in
keshriya ji about 60 km south of Udaipur. There
is great craze of this marble because it has
white jali with light or dark green base which
shines very good after polishing Block recovery
is very little as lot of cracks are found and
hence it is generally used for making chips and
crazy. This variety is actually serpentine rock
but in trade it is known as green
marble.
Other
Marble
Others types of marble are
found in different parts of Rajasthan. Yellow
marble which actually shally lime stone and
takes good polish is available in Jaisalmer.
Marble deposits of Bhainsalana in Jaipur
district is known for its black strips. In Pali,
Marble deposits exists near Bar and Sendra. It
is mainly pink coloured with various shade and
strips . Different types of marble is also found
in Ajmer, Jahazpur, Bundi. etc. but the deposits
are very small.
In Rajasthan mining is
mostly done by open cast method. Only in Makrana
at Chancer area underground mining method has
been adopted where it has been mines upto 100
meters depth but, the deposit is of spotless
white marble. Mining does not come under the
head of industry hence it is deprived of the
benefits available to an industry, Moreover,
financing institutions are also reluctant to
finance the mines. Therefore, mechanised mining
is not developing rapidly. To increase the
marble production it becomes necessary to
mechanise the mine and minimise the use of
explosives to reduce the breakage so that it can
cope-up with the increasing demand of marble
blocks by the diamond gang saw and other
conventional machines.
Marble Based
Industries
Marble sawing and polishing
industry of Rajasthan is one of the most
important mineral based industry. 
Main centre of
this
industry is still Makrana.
There are more than 1000 conventional
sawing units and more than 100 diamond gang saw
are under operation. In addition about 200 edge
cutting and polishing units are also working.
They comprise both imported and indegenious
machines. Among imported machines. Italian
machines out number those from Germany. A survey
reveals that the total installed capacity of
sawing at Makrana is about 5.00 lac tonnes per
annum and the production of blocks at Makrana is
about 205 lac tonnes and about 2.00 lac tibbes
us received from other areas for processing like
Rajnagar, Keshriya ji , Babarmal etc. Thus the
total raw material comes to 4.5 lac tonnes which
is short of the installed capacity.
The
Makrana area is almost saturated for the growth
of the marble industry
and therefore, in mining and
processing of marble Udaipur district is fast
developing as the second centre of marble based
industry. Udaipur is also well connected by Air,
Rail and Road which also contributes as major
role to its fast developments. In Udaipur about
20 conventional and 8 dimond gang saw units are
functioning Besides about 60 cutting, polishing
and tiling units are under operation. At
Rajnagar 14 diamond, 15 conventional and in in
Chittorgarh 4 diamond and 12 conventional gang
saw machines are working. The total gross sawing
capacity of Udaipur district is more than 2 lac
tonnes per annum. Total production marble blocks
is some where about 1.5 lac tonnes which is much
below the sawing capacity. Hence there is acute
need of mechanised and wide scale mining of
blocks so that it can copeup with the demand and
reduce the gap between demand and supply. Now a
days Rajasthan is exporting mirror polished
marble tiles in various sizes and
thickness
