Road, Ulubari, Guwahati-781007, Mobile : +91-9435106080 3 FOREWORD The Miscellaneous Publication 30 Series of the Geological Survey of India brings out concise information on the geology and mineral resources of the states of India. The present volume Part IV, Vol. 1(ii) of the series, pertaining to the states of Manipur, Mizoram, Nagaland and Tripura, is a revised and updated version of the first edition published in 1974. During the span of three and a half decades since the first edition was published, enormous knowledge has been added in the sphere of geology of the area warranting a re- vised edition of this volume. Geological and Mineral Map of each state presented in this volume is a modified and updated one. Geological Survey of India continues its dedicated work in different realms of Earth sciences. Revisions in the lithostratigraphic succession of the rocks based on the recent ad- vances in geological mapping and laboratory works have been necessary. The coal horizons of Nazira Coalfield and that of Changkikong-Japukong region appear to be the most important among the economic minerals found in Nagaland so far. Various other important minerals like chromite, magnetite, nickel-ore and limestone, have been located in Nagaland. Chromite is reported mainly from Ukhrul, Gamnom and Moreh areas of Manipur. The lignite, associated with clay, occurs in Kangvai area of Southern Manipur. Good quality clay deposits are scattered all over the state of Tripura and can be used for manufacture of sanitary wares, sewerage pipes, electric insulator, fillers in paper, rubber, paint and ceramic industries. Silica sands are also known to occur near Baidyathakurpara, Dukli, Maheshkhola, Anandanagar, Mohonpur and around Dasaram Bari areas of Tripura. Occurrence of shell limestone, coal, hard sandstone bands (suitable as building material), saline springs and a few gas seepage have been located in Mizoram. I wish, the publication with updated knowledge-base on the geology and mineral resources of the state of Manipur, Mizoram, Nagaland and Tripura will be of immense use to the students of geology as well as to the professionals and entrepreneurs interested to make investment for developing mineral industry in the region which will augment the economic growth of the area.

  • Displaced Brus from Mizoram in Tripura: Time for Resolution
    Displaced Brus from Mizoramin Tripura: Time for Resolution Brig SK Sharma Page 2 of 22 About The Author . Brigadier Sushil Kumar Sharma, YSM, PhD, commanded a Brigade in Manipur and served as the Deputy General Officer Commanding of a Mountain Division in Assam. He has served in two United Nation Mission assignments, besides attending two security related courses in the USA and Russia. He earned his Ph.D based on for his deep study on the North-East India. He is presently posted as Deputy Inspector General of Police, Central Reserve Police Force in Manipur. http://www.vifindia.org ©Vivekananda International Foundation Page 3 of 22 Displaced Brus from Mizoram in Tripura: Time for Resolution Abstract History has been witness to the conflict-induced internal displacement of people in different states of Northeast India from time to time. While the issues of such displacement have been resolved in most of the North-eastern States, the displacement of Brus from Mizoram has remained unresolved even over past two decades. Over 35,000 Brus have been living in six makeshift relief camps in North Tripura's Kanchanpur, areas adjoining Mizoram under inhuman conditions since October 1997. They had to flee from their homes due to ethnic violence in Mizoram. Ever since, they have been confined to their relief camps living on rations doled out by the state, without proper education and health facilities. Called Internally Displaced Persons (IDPs), some of the young Brus from these camps have joined militant outfits out of desperation. There have been several rounds of talks among the stakeholders without any conclusive and time-bound resolutions.

Both erosion and deposition are continuous processes in the river in an attempt to reach a new equi- librium in channel geometry and morphology by the ever dynamic nature of flow. Erosion and deposition of the river have link to land use and land cover (LULC) as the land cover is under constant change in a dynamic landscape constantly shaped by continuous erosion and deposition. The objective of the present work is to evaluate the extent of erosion and deposition along the Brahmaputra river and change in the LULC of the Brahmaputra river in Assam, India. Remote sensing and geographic information system (GIS) techniques were utilised to extract information from Landsat images. Total area of erosion and deposition during 1973–2014 was 1557 and 204 km2, respectively.
