Some structures of non-diastrophic origin - are described from the Lower Siwalik (Nahan) strata of the Haldwani-Tanakpur area. Some are epigenetic and the others are syngenetic or penecontemporaneous. The epigenetic structures simulate structures formed due to the penecontemporaneous slumping of sediments; but the presence of cross-bedding passing undisturbed through them negates this mode of origin. They are considered to be due to 'Liesegang banding'.
Among the syngenetic or penecontemporaneous structures are groove casts which are uncommon in Siwaliks. It is suggested that though there might have been occasionally grooving, the grooves were rarely preserved because of the turbulence of the environment. The other structures described comprise those due to slump deformation and intrusion of soft sediments, and those due to organic activities.

On the basis of detailed field studies. the authors postulate that there is a wrenchfault on either side of the Kosi River, and that both of them pass into thrusts along the southern margin of the Sub-Himalayan belt.- Thematic Cartography and Remote Sensing

A number of magnetic zones, faults, lineaments and domal structures were interpreted based on the analysis of aeromagnetic data. Magnetic basement depth and thickness of the sediments were computed by means of quantitative interpretation techniques. A number of alternate basement ridges/highs/uplifted blocks and depressions/lows/downthrown blocks were also delineated. The lithological variations, major folding and faulting patterns, circular spectral anomalies and other geological structures were interpreted from IRS-1C satellite data. The tectonic framework and deformational history of the basin were deduced. The results obtained from the interpretation of aeromagnetic and satellite data were then integrated and the potential zones of hydrocarbon deposits and vulnerable areas for earthquake occurrence were derived.Keywords
