Dr. Ranawat’s main activity of research has been in the
field of geology of mineral deposits with reference to study of
host rock petrology, mineralogy, mineralization structures &
textures, fluid inclusion study, granulometric studies as well
as their environmental & risk-benefit assessments. Efforts
were made, with moderate success, to rationalize the mining and
environmental regulations of the Union and the State Governments.
this scheme of work the following mineral deposits have been studied:
Deposits of Rajasthan, Talc & Anthophyllite Deposits of
Udaipur Area, Scheelite Prospect of Kararavav, lead-zinc Deposit
of Rampura- Agucha & Jhamarkotra rock phosphate deposits.
of the first Fluid Inclusion Laboratories in India was set
up first with a pyrophyllite-body heating stage, then with
a CHAIXMECA micrthermometric equipment. FI Lab’s unreserved
facility was extended to several researchers from a number
of institutions of the country. Help and guidance was also
provided to a number of university and state government departments
in setting up of ore petrology and fluid inclusion laboratories.
identification of the cataclastic host rocks of the Mando-Ki-Pal
Fluorspar Deposits resulted in change of exploration and utilization
strategy of the resources (Publication # 1 & 2).
study of Karara Fluorspar Deposit resulted in identification
of an explosive sub-aerial volcanic vent and its significance
in understanding the nature of Malani volcanism and volcanogenic
mineralization in Western Rajasthan. Melt inclusions in feldspar
and quartz phenocrysts of these rocks have were also described
(Publication # 5 & 7).
inclusion study of the fluorspar deposits of Rajasthan has
helped in understanding the varied physico-chemical environments
of mineralization (Publication # 3, 5, 7; Ph. D. # 1,2).
holistic geologic study of the Precambrian ultramafic rocks
of Jharol area helped to understand the conditions of anthophyllitization
and steatitization of ultramafic rocks and identification
of C-O-H as the main components of the metamorphic hydrothermal
fluid regime of the area (Terra Cognita 1986, Ph. D. #3).
study of asbestos resources of Rajasthan (Publication #10).
This study and its follow up programs resulted in Government
of India’s decision to lift ban on asbestos mining and
processing in India (2001). Governments of Canada and Brazil
also demonstrated interest in the out come of the study and
sent their representatives for firsthand assessment of the
study of the scheelite mineralization of Kararavav area revealed
the economic potentiality of the skarn at the contact of Delhi
calcareous formations and the Post- Delhi acid magmatic rocks
(Ph.D. #4, 29th IGC, Kyoto, 1992, Abstract).
study of the Rampura-Agucha lead-zinc deposit revealed its
metamorphic characteristics; the study was applied for quantification
of liberation characteristics through granulometric studies
(Ph.D. #5; Publication # 8,9).
Rock Phosphate Deposit is the premier phosphate producing
center of India that is being utilized by M/s Rajasthan State
Mines and Minerals Limited (RSMML). The ore of Jhamarkotra
requires beneficiation for its marketing. Froth flotation
studies on the Jhamarkotra ore and its process response were
studied to improve the ore recovery (Project # 7). Subsequently,
studies have been taken up to utilize the great quantity of
bulk circuit tailing under Green Chemistry Program (Project
# 9) for utilization as a fertilizer.
- A silvery
white metallic mineral from Jahazpur, Rajasthan, that has
been baffling geologists was identified as native antimony
and its report was submitted to The Directorate Mines and
Geology, Government of Rajasthan in February 2003 and results
have also have been published in the Journal of Geological
Society of India, February 2005.
findings were delivered as Ph.D. theses, journal publications,
reports, and presentations of results at national and three International
Congresses abroad. Research work was essentially undertaken as
the Principal Investigator of research projects on mineral resources
Dr. Ranawat promoted studies and awareness in environmental geology.
One of the first papers on the subject was published by us in
1976 (Publication # 18). Efforts in promotion of environmental
awareness are continuing, through organization of seminars, etc.
Dr. Ranawat attended and presented research papers at several
conferences, including the 5th International Volcanological Congress,
New Zealand (1986); 28th International Geological Congress, Washington
DC (1989); 29th International Geological Congress, Kyoto (1992),
also Chaired the oral session on "ORE FORMING PROCESSES IN
ISLAND ARCS AND ACTIVE CINTINENTAL MARGINS" during the 29th
IGC. Convener of the during-the-Congress Short Course on "PROCEDURES
AND APPLICATION OF GRANULOMETRIC ANALYSIS OF ORE MINERALS"
during the 30th International Geological Congress, Beijing, 1996

regulations in relation to SSI units and mining V/s forest land
