Aerial photographs-a useful aid in delineation of the ophiolite belt along indo-burmese border
- 19 Downloads
The eastern border of India with Burma represents a fairly young tectonic zone. The main rock types of the area belong to the Disang Group of Eocene to Upper Cretaceous age. The Ophiolites have concordant relationship with these rocks. The 200 km long belt of NNE -SSW trending Ophiolite suite of rocks in Manipur and Nagaland is of great academic importance as it has been postulated as probable plate boundary along which ophiolites have been emplaced. It holds immense economic importance too, being the carrier of elements of strategic mineral importance, such as nickel, chromium, platinum etc.
Photo-interpretation has been successfully used in delineating the extensions of and location of the important NNE-SSW. lineament along which ophiolite has been emplaced. It has been possible to demarcate .the ophiolite bodies on the basis of their distinct photo-characters from that of sedimentaries. An attempt has also been made to decipher its structural and tectonic relationship with country rocks.
