The
Petrology Laboratories at Hyderabad (Headquarters) and the Regional
Centres at Bangalore, New Delhi, Shillong, Nagpur, Jaipur and
Jamshedpur are
engaged with the petromineralogical studies of different geological
materials, with emphasis on radioactive minerals. They have
a large work-spectrum ranging from characterisation of radioactive
and associated non-radioactive rocks, minerals, soils, sands
and stream sediments in the front-end to the ore characterisation
for mineral processing in the back-end of the whole gamut in
the exploration for atomic minerals. The laboratories cater to
the needs of multidisciplinary scientists of AMD like geologists,
geophysicists, geochemists and geochronologists. The laboratories
are equipped with Advanced research polarising microscopes of
Leitz-make (Germany) for transmitted and reflected
light studies with attachments for many specialized studies viz.
reflectivity and microhardness of ore minerals, microthermometry
apparatus of Chaixmeca-make (France) for study of fluid inclusions. Facilities
are also available for image analysis, automatic photography
and fluorescence studies. Some of the attachments for specialised
studies are also available at regional centers. Nearly thirty
microscopes are available.
The laboratories
are engaged in:
petrographic and mineragraphic
characterisation of common rock forming minerals and ore
minerals;
petromineralogical and petrometallographic studies
of ores and gangue minerals of uranium, thorium, and rare
metals;
heavy mineral identification of river and beach placers;
petromineralogical characterisation of rocks
and minerals for radioisotopic dating;
fluid inclusion studies to decipher geotherms
and geobarometric; and
solid state nuclear track detection (SSNTD) using
alpha-sensitive cellulose nitrate film.
