Work Description:

• Preliminary landform mapping (geomorphic expressions) in Himalayan mountain front of NE Himalaya using data from earlier studies , Satelite imagery and published literature along Itanagar section of Arunachal Pradesh is in progress.

Preliminary geological map along the Lohit valley section in NE Himalaya.

Fig.37.2:
Geomorphic and stratigraphic expressions of active deformation in Himalayan front.

• (a) Digitally processed Cartoset-II image overlaid with contour showing distribution of fluvial terreces and fans along the Dikrang river section in NE Sub Himalaya.
• (b) The growth of strath terraces over steeply dipping Siwalik beds, suggesting active deformation and incision.
• (c) Section of T3 terrace exposed in the road cutting showing soft sediment deformation as (c₁) deformed cross bedding, (c₂) folded bed and pseudonodules bordered by undeformed bed suggesting discreet deformation events.
