describe any five features of central highlands of india
Eastern Himalaya
In the Mesozoic era the whole of the worn - down plateau was under sea . In this expansive shallow sea , which covered most of Assam ( India ) and Bhutan , chalk deposits formed from seawater tides oscillating between land and sea levels . During subsequent periods , tertiary rocks were laid down . The Paro metamorphic belt may be found overlying Chasilakha - Soraya gneiss in some places . Silurian metamorphics in other places suggest long denudation of the surface . This was the time of Alpine mountain formation , and much of the movement in the palaeozoic region was probably connected with it . The Chomolhari tourmaline granites of Bhutan , stretching westwards from the Paro chu and ats much depth below the present surface , were formed during this period of uplift , fracture and subsidence .
