Exploring possibilities for joint projects in geomagnetism was the focus of an Indo-U.S. workshop on “Geomagnetism in Studies of the Earth's Interior” held in Pune, India, August 22–26, 1994. The 40 participants included delegates from 14 of India's major centers of geomagnetic research. Participants considered the meeting mutually beneficial and agreed that communication should continue through regular meetings.

T. M. Mahadevan reviewed the deep crustal structure and crustal provinces of the Indian subcontinent. Seismic, gravity, electrical conductivity, and heat flow, as well as magnetic data were used to classify these provinces, which have the greatest Moho depths in the southern shield (45 km) and Himalayan (70 km) areas, and shallowest (20–30 km) along the western continental margin. The major plate tectonic features of the Indo-Asian region were reviewed by M. N. Qureshy. He pointed out that gravity and magnetic data have revealed some possible suture zones in Afghanistan, Bangladesh, India, Iran, and Pakistan. The Satpura Suture (Narmada-Son lineament) of Peninsular India block is one of these.
