- Barind Tract
Barind Tract (alternately called the Varendra Tract in English and Varendra Bhumi in Bengali) is the largest
Pleistocene era pysiographic unit inBangladesh and theBengal Basin . It covers most of Dinajpur, Rangpur, Pabna, Rajshahi, Bogra, and Joypurhat districts ofRajshahi Division . It is fragmented, being made up of several separate sections in the northeastern part of the country, covering a total area of approximately 7,770 km² of mostly oldalluvium . On the eastern edge of the tract is a lower faultescarpment . Through the fault troughs run the little Jamuna,Atrai and Lower Punarbhaba rivers. To the west, the main area is tilted up, some of it being more than 15 m higher than the rest of the tract and the adjoiningMahananda River floodplain . To the east this area is tilted downwards, passing under theAtrai River basin.cite web | url=http://banglapedia.search.com.bd/HT/B_0309.htm | title=Barind Tract | publisher=banglopedia.com | accessdate=2007-08-19] The climate of the tract differs from that of much ofIndia , in that more extreme temperature variations (ranging from 45 degrees Celsius down to five degrees Celsius) are encountered there. It is divided into three units: The Recent Alluvial Fan, the Barind Pleistocene, and the Recent Floodplain. These are divided by long, narrow bands of recentalluvium .
