Geography of Mizoram
Mizoram is a land of rolling hills, valleys, rivers and lakes. As many as 21 major hills ranges or peaks of different heights run through the length and breadth of the state, with plains scattered here and there. The average height of the hills to the west of the state are about 1,000 metres (3,300 feet). These gradually rise up to 1,300 metres (4,300 feet) to the east. Some areas, however, have higher ranges which go up to a height of over 2,000 metres (6,600 feet).
Rivers
- Chimtuipui River, also known as Kaladan originates in Chin State in Burma and passes through Saiha and Lawngtlai district in the Southern tip of Mizoram
- Tlawng is a river of Mizoram, northeastern India.[1] Tributaries include the Tut, Teirei and the Ngashih. Aizawl lies in the Tlawng valley.
- Tutis a river of Mizoram, northeastern India.[2] It is a tributary of the Tlawng River.[1]
- Tuirial is a river of Mizoram, northeastern India. It flows in a northerly direction.[3] It is impounded by the Tuirial Dam.
- Tuivawl flows through the northern territory and eventually join the Barak River in Cachar District.
Lakes
- The Palak lake, the biggest in Mizoram is situated in Saiha District which is part of southern Mizoram covering 30 hectares (74 acres). It is believed that the lake was created as a result of an earthquake or a flood. The local people believe that a village which was submerged still remains intact deep under the waters.
- The Tam Dil lake is a natural lake situated 85 km (53 mi) from Aizawl. Legend has it that a huge mustard plant once stood in this place. When the plant was cut down, jets of water sprayed from the plant and created a pool of water, thus the lake was named Ţamdil which means of 'Lake of Mustard Plant'. Today the lake is an important tourist attraction and a holiday resort.
- Rih Dil is located in Burma, a few kilometres from the India-Burma border. It was believed that the departed souls pass through this lake before making their way to Pialral or heaven.
Waterfalls
- Vantawng Falls is located 5 kilometres (3.1 mi) south of Thenzawl in Serchhip district in the Indian state of Mizoram. It is about 30 kilometres (19 mi) from Serchhip and 137 kilometres (85 mi) from Aizawl.[4]
Mountain Range
- Phawngpui Tlang also known as the Blue Mountain, situated in the south-eastern part of the state, is the highest peak in Mizoram at 2,210 metres (7,250 feet).
- Hmuifang With an elevation of 1619 metres, the mountain is still covered with virgin forests reserved since the Mizo Chief's time.[5] Hmuifang is the way to Lunglei.
- Reiek with an elevation of 1548 metres, overlooking Aizawl and offers view of the surrounding valleys and hills, on a clear day the plains of Bangladesh can be seen from the top of the hill. Reiek Hill is surrounded by thick lush green temperate trees and bushes.[6]
Geology and minerals
The folded structure of the Mizoram ranges are at the junction of two moving tectonic plates(Indian and Burmese Desi Kachar 1974). On 19 April 2011 there was a 4.3 earthquake about 10 km North of Kolasib and a 6.4 was recorded on 4 February 2011. Mizoram is in the highest zone 5 for earthquakes.[7]
The folded hilly or mountainous North South belts, with perpendicular faults, comprise sediments of the Surma (Middle Bhuban Formation), Barail and Tipam groups. There is Aluvium in river beds consisting of deposits of argillaceous and arenaceous sandstones, shale, siltstones and mudstones and greywacke. A 560m thick rock succession of the Middle Bhuban type exposed between Bawngkawn and Durtlang shows 7 normal and 7 reverse magneto strata (North and South pole reversals) showing its age to be around 20 Million years old.[8] The rock system is generally weak, unstable, weathered and prone to seismic and weather influence producing landslides. The soft, black to grey rock is used locally for building materials and for low trafficked road construction work. There are no useful minerals of economic significance apart from clays in the River Tlawng beds together with deposits of sand and gravels. Typical soils are sandy loam, clay loam that have been heavily leached due to the high slopes leaving it porous and lacking in minerals or humus.
A number of oil and gas exploration activities have taken place due the geological condition with which Mizoram has been formed, leading to the possibilities and high expectation that reserves would be confirmed. France, Russia and Cyprus as well as several Indian companies have already signed a 12% oil and 10% gas royalty arrangement with proceeds going direct to Mizoram state on any production (April 2009)
