National Geophysical Research Institute

The National Geophysical Research Institute (NGRI) is a geoscientific research organization established in 1961 under the Council of Scientific and Industrial Research (CSIR), India's largest Research and Development organization. It is supported by more than 200 scientists and other technical staff whose research activities are published in several journals of national and international interest.

Research areas covered by this institute include hydrocarbon and coal exploration, mineral exploration, deep seismic sounding studies, exploration and management of groundwater resources, earthquake hazard assessment, structure of Earth's interior and its evolution (theoretical studies), geophysical instrument development and geothermal exploration.

The major facilities available at NGRI include:
 * Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometer (LA-MC-ICPMS) with clean chemistry laboratory facility.
 * Mineral Physics Laboratory with high-pressure Diamond Anvil Cell (DAC), ultra high resolution (0.02/cm) double monochorometer, and micro-Raman spectrometer.
 * High-pressure laboratory consisting of Keithly electrometer, strain-measuring sensors, universal testing machine (100 tons), and Bridgeman-Birch high-pressure apparatus.
 * In-situ stress measurement facility consisting of hydraulic equipment.
 * Rock magnetism laboratory consisting of astatic magnetometer, digital spinner magnetometer, alternating magnetic field and thermal demagnetizers, high-field and low-field hysteresis and   susceptibility meter.
 * Geochemical laboratory consisting of fully automated X-ray Fluorescence Spectrometer (XRF), Atomic Absorption Spectrometer, Inductively Coupled Plasma Mass Spectrometer (ICPMS), and Electron Probe Micro Analyzer (EPMA).
