Resource persons and students of Nagaland University during
a field training in Mokokchung district on April 30.
- DIMAPUR — The
Geography department of Nagaland University, in collaboration with the
Inter-University Accelerator Centre (IUAC), New Delhi, successfully organised a
national workshop on ‘Methods of geochronology and research opportunities’ on
April 29 and 30 at Lumami campus.
- An update from the university stated that the workshop was
conducted with the primary objective to foster a comprehensive understanding of
geochronological methods—scientific techniques that help decode earth's surface
processes, environmental changes and geological events.
- It mentioned that geochronology serves as a crucial toolkit
for reconstructing past climates and informing future research in an era of
rapid scientific advancement and growing concerns about climate and
environmental change.

- The programme began with an introductory address by its
organising secretary, Dr. Manasi Debnath, followed by welcome speech delivered
by Prof. Wangshimenla Jamir, head of department and convenor.
- The resource persons were Prof. Milap C Sharma from JNU, New
Delhi; Dr. Pankaj Kumar from IUAC, New Delhi;, Dr. Ambuj Mishra from IUAC, New
Delhi; Dr. Jaishree Sanwal from JNCASR, Bangalore; Prof. HJ Syiemlieh from
NEHU, Shillong; and Dr. T Walling from Nagaland University, Kohima campus.
- A major highlight of the event was the inauguration of the
Glacier and Mountain Research (GLAMOR) Laboratory by Prof. Bendang Ao, vice
chancellor in-charge, and Prof. MS Rawat, dean of the School of Sciences.
- The workshop emphasised the significance of advanced
geochronological techniques such as optically stimulated luminescence (OSL)
dating, AMS ¹⁴C, ¹⁰Be/²⁶Al exposure dating, and zircon geochronology—especially
in the context of the northeast Indian region including Nagaland, which hold
immense potential for cross-disciplinary research.
- On April 30, a field training was conducted in Mokokchung
district, where participants explored the tertiary sediments—the final stages
of Himalayan orogeny following the collision of the Indian and Eurasian plates.
- It stated that the participants studied fault structures,
sedimentary features and evidence of the changes in river courses due to the
active tectonics in this region. It added that the local sandstone and shales
offered insight into ancient Tethyan marine conditions that contributed to the
formation of present-day Nagaland.
- Report stated that the workshop underscored the urgent need
for extensive geochronological research to understand regional landform
evolution and support sustainable development planning.
