Mining and minerls

The mineral and quarrying industry is more than USD 2 bn dollars and employs more than 14000 workers Has a total mineral reserve of more than 19000 Million tonnes Possesses one of the highest reserves of lignite, limestone, perlite, and clay deposits in India Has strength in non-metallic minerals, which offer the best prospects for exploitation
It is the only producer of minerals such as Agate and Chalk in the Country
Major mineral producing districts are Kutch, Junagadh, Jamnagar, Porbandar, Bhavnagar, Rajkot, Amreli, Banaskantha and Sabarkantha. Major industries-Lignite-based power plants, Bauxite-based calcinations, refractory and abrasive units, silica sand-based glass units, Bentonite-based pulverizing units, Organo-clay units, and China-clay & Fire-clay units, Fluorite based beneficiation plant, Marble and Granite Industry Government Initiatives Awarded best state in e-governance initiatives and employment category in 2008
Urban development initiatives for high quality living. Simplification of processes and single window approach for investors. International campaigns for investment promotion across sectors. Wide array of choices for tourists right from heritage monuments, archeological sites , wildlife and beaches. Favourable policy and regulatory environment. Industrial Policy 2009– for high quality socio economic development. Sectoral policies for promotion of investment and growth. Incentives under SEZ and Industrial Area Development.     A leader in encouraging private participation under public-private partnership concept.
Mineral based Industries. GMDC using world's best known and environment friendly mining technology - TAKRAF of Germany- for excavation Panandhro mines in Kutch district. GMDC has been mining bauxite in these two centres (Gadhsisa group of Mines in Kutch and Bhatia Mines in Jamnagar).Plant Grade bauxite is being marketed to refractory industries, chemical industries.Large quantity production of acid grade and metallurgical grade flourspar which are widely used for steel, chemical and metallurgy industry. Plant grade Bauxite calcined at Gadhshisha for value addition
Educational InfrastructureGujarat has the presence of some of India's top education institutes. Central Glass and Ceramic Research Institute (CGCRI) was established at Ahmedabad in 1977.
National Institute of Design (NID) – World's premier design institute.The Centre caters to the needs of ceramic industries in Gujarat and neighbouring states, manufacturing traditional ceramics such as ceramic floor and wall tiles, vitrified and porcelain tiles, sanitary ware, stone ware, table ware and decorating wares. Lalan college & Government Engineering College in Bhuj offer degree and diploma courses in Mining, respectively. Engineering college at Morbi (Rajkot) offers courses in Ceramics and Gujarat University, Ahmedabad offers degree course in Geology. MS University in Vadodara offers degree and Ph.D. courses in Geology

Geological Hazards

Seismology, Seismotectonics and Seismic Microzonation GSI has a legacy of more than 150years of earth science studies. Along with geological mapping, mineral exploration and number of other earth science research, GSI has always nurtured earthquake related studies. Pioneering work by Thomas Oldham and R.D. Oldham in the 19th Century virtually laid the foundation of modern seismology. The Geological Survey of India has been carrying out macroseismic survey (post-earthquake damage surveys for assessment of intensity) of earthquakes for now over 135 years. The first account of such a study dates back to Cachar earthquake of 1869. Thomas Oldham, who investigated the event, later published a Catalogue of Indian earthquakes dating from historical times to 1869. Jones (1885) conducted studies for the 1885 Kashmir earthquake that took a toll of 3000 human lives and caused widespread destruction in the Kashmir valley. The Great Assam earthquake of 1897, one of the most severe and destructive manifestations of seismic energy release the world has witnessed so far, was investigated in detail by Sir R.D. Oldham. The accounts, observations and analyses of that catastrophe were brought out in the form of a Memoir (Vol. 29) of GSI. The first seismic zoning map of the country was prepared by GSI in 1935. With that beginning and consequent updating with state of the art technology, GSI has been engaged in multifarious earthquake studies including macroseismic survey of every great Indian earthquake, aftershock studies by establishingtemporary digital seismic networkto interpret causative fault and source mechanism, study of activefaults as seismic source, observational seismology with Broad Band observatories at Jabalpur and Nagpur, telemetered seismic network at Khandwa, Madhya Pradesh, tomographic studies, seismotectonic / neotectonic studies and seismic microzonation studies for urban centers etc. Bureau of Indian Standards delineates Seismic Zones of India with inputs from GSI. Indian sub-continent has a diverse tectonic setting. GSI made a neat contribution in bringing out the ‘Seismotectonic Atlas of India and it environs’, which is a comprehensive multi-thematic atlas encompassing integration ofgeological, geophysical, seismological information up to 1
