Hills of Purvanchal Origin of Himalayas according to Kober's Geosyncline theory  According to Kober, folded mountains like Himalayas are formed in geosynclines (shallow seas)  According to Kober, hard fronts (phreatogen), Brownian Cratogen and Indian Phreatogen were present on both sides of the Tethyl Geosyncline.  Due to erosion of these fronts, rivers started depositing sediments in the geosyncline, due to which the bottom of the geosyncline started sinking and the fronts started sliding towards each other, due to which the geosyncline continuously narrowed and started applying horizontal pressure on the sediments at its bottom.  Due to this horizontal pressure, folding started in the sediments and a folded mountain in the form of Himalayas originated.  Stages of division Division of Pangea Division of Gondwanaland Himalayas originated on the basis of plate tectonics theory  When about 250 million years ago in the Permian period of Paleozoic era, all the continents were connected as a single supercontinent Pangea and all the oceans were connected as Panthalassa.

Cont.7524821440,7000360672  Powered by Division of Pangea  Division of Pangea took place 200 million years ago in the Triassic period of the Mesozoic era, in two huge parts, Laurentia (including North America, Europe, Asia, Greenland, etc.) and Gondwanaland (including Africa, South America, India, Australia, Antarctica, etc.) and the displacement of Laurentia towards north and Gondwanaland towards south started.  The sea formed between both the landmasses was named as Tethys Sea. Division of Gondwanaland  About 145 million years ago in the Jurassic period of the Mesozoic era, Gondwanaland got divided again and after separating from it, the displacement of the Indian plate towards north started, which led to the formation of a new ocean, the Indian Ocean. Collisions of plates  60 million years ago, in the Paleocene era of Tertiary era, the Indian plate collided with the Eurasian plate due to which the crustal rocks and sediments of Tethys Sea were uplifted along the Indus-Tsangpo junction region. Presently, the Indus River and the Yarlang Tsangpo (Brahmaputra) flow along this junction region. Origins of fold mountains  In the Eocene period of Tertiary Era (45-35 million years ago), folding of the rocks of Tibet Plateau, volcanic eruptions led to the formation of Trans Himalayas and folding of the sediments of Tethys Sea, which led to the rise of Greater Himalayas, Middle Himalayas and Shivalik ranges in Oligocene, Miocene and Pliocene respectively.  After this, the Indian plate rotated counterclockwise and closed towards the east, due to which wide valleys were formed towards the west.

Macrostructural Features of the Himalayas Axis folds Structural Greater width of the features of the Arc shape Western Himalayas Himalayas Steep southern slope 1. Syntaxial folds  The Himalayas are found to have axial folds near Namcha Barwa and Nanga Parbat. Where rivers form Syntaxial Bends and the reason for its formation is the strong compressional force generated by the hard rocks of Aravalli in N-W and Shillong Plateau in N-E on the sediments of Tethys.  From here, the Himalayas turn and join the ranges like Purvanchal Himalayas in the east and Hindukush, Suleman in the west. 2. Arc shape  This is due to the retreat of the weaker rocks of the Himalayas because the rocks of Tibet were very strong. 3. Steep southern slope  Due to the relatively higher speed of the Indian plate, the southern slope of the Himalayas has become steep. 4. Western Himalayas being wider  Due to the collision of the plate in the east, the western part was relieved of pressure, which led to the expansion of the Western Himalayan ranges.  The width of the Western Himalayas is about 500 km, while the width of the Eastern Himalayas is about 200 km.

(c) Bangar  This is a plain formed by ancient alluvium of the Middle Pleistocene period.  This is a higher region than Khadar.  Flood water generally does not reach this region.  The Bangar region is mainly found in the areas between two rivers (Doab region).  The Doab of Ganga-Yamuna and the plain of Sutlej are examples of this.  Bangar has two regional divisions - (1) Barind Plain (2) Bhur region. 1. Barind Plain'  'Barind Plain' is located in the deltaic areas of Bengal and in reality it is the ancient delta of Ganga. It was formed in the Pleistocene period and has again eroded to become an area of laterite soil. 2. Bhur  The Bhur structure has developed in the region of Upper Ganga-Yamuna Doab. It is formed by deposition by wind in the Pleistocene period.  Due to excessive irrigation in some areas of Bangarh soil, white layers of salt get deposited on the land. This is known as 'Reh' or 'Kallar'. (d) Khadar  It is formed by the deposition of new alluvium and is a relatively low region.  Due to the abundance of 'Chika' in the soil of this land, the capacity to retain moisture is high.  Flood water of rivers reaches here almost every year, due to which it remains fertile.  The regions of Bihar, Eastern Uttar Pradesh, West Bengal which are adjacent to river valleys come under Khadar region.  The delta region of Ganga-Brahmaputra is also an example of Khadar.  In Uttar Pradesh and its neighbouring regions, such low lying areas are called Khadar while in Punjab it is called 'Bet'.
