Indo-Myanmar (Burma) Ranges (IMR) have a distinct entity in the tectonic framework of Eastern Himalaya and the Southeast Asia. The IMR, which is thought to be northern prolongation of the Indonesian island are linking with the Himalaya possibly along the Tidding Suture Zone, is believed to have evolved due to subduction of the Indian plate below the Myanmar (Burma) plate. In the process, the range evolved as an accretionary prism of imbricate thrust system where obducted oceanic crust (ophiolites) has intermingled with the sediments. As a result, all geological, geophysical and tectonic features, unique and pertinent to a subduction plate boundary, are found in this range. In other words, the range is one to the best onland subduction plate boundary regions in the world serving as an ideal type area for both field and laboratory studies. In spite of all these interesting geological, geophysical and tectonic features, the region still remains as one of the least explored parts of the world.
