Geomorphological and Statistical Assessment of Tilt-Block Tectonics in the Garhwal Synform: Implications for the Active Tectonics, Garhwal Lesser Himalaya, India

Active tectonics is manifested in geomorphological features such as drainage basins and drainage patterns. Geomorphic parameters asymmetry factor <i<(AF)</i< and transverse topography symmetry factor <i<(T)</i< is calculated for 94 third order basins of the Garhwal synform to...

Geomorphic parameters asymmetry factor <i<(AF)</i< and transverse topography symmetry factor <i<(T)</i< is calculated for 94 third order basins of the Garhwal synform to decipher the tilt-block tectonics based on remote sensing and geographical information system (GIS) techniques. The quantitative analysis of the <i<AF</i< suggests that all the 94 basins are asymmetric and gentle to steeply tilted, indicating active tectonics and early and late stage of development, respectively. The mean vector magnitude (<i<θ<sub<v</sub<</i<) of <i<T</i< suggests the migration of the basin stream towards the south in most basins (60%), suggesting a unidirectional tilting of the tectonic block. The χ<sup<2</sup< test for statistical significance indicates that the <i<θ<sub<v</sub<</i< is significant for southern and northern limb basins. The χ<sup<2</sup< test affirms that the third order basin position on either side of the main channel of the river basin influences the tilt direction. The regional tectonics suggests migration of the Lansdowne klippe towards the south, as the majority of third order basins show southward tilt. The study provides a quick appraisal of tilting in the tectonic blocks of active margins, such as in the Himalayas.

abstract	Active tectonics is manifested in geomorphological features such as drainage basins and drainage patterns. Geomorphic parameters asymmetry factor <i<(AF)</i< and transverse topography symmetry factor <i<(T)</i< is calculated for 94 third order basins of the Garhwal synform to decipher the tilt-block tectonics based on remote sensing and geographical information system (GIS) techniques. The quantitative analysis of the <i<AF</i< suggests that all the 94 basins are asymmetric and gentle to steeply tilted, indicating active tectonics and early and late stage of development, respectively. The mean vector magnitude (<i<θ<sub<v</sub<</i<) of <i<T</i< suggests the migration of the basin stream towards the south in most basins (60%), suggesting a unidirectional tilting of the tectonic block. The χ<sup<2</sup< test for statistical significance indicates that the <i<θ<sub<v</sub<</i< is significant for southern and northern limb basins. The χ<sup<2</sup< test affirms that the third order basin position on either side of the main channel of the river basin influences the tilt direction. The regional tectonics suggests migration of the Lansdowne klippe towards the south, as the majority of third order basins show southward tilt. The study provides a quick appraisal of tilting in the tectonic blocks of active margins, such as in the Himalayas.

Geomorphic parameters asymmetry factor <i<(AF)</i< and transverse topography symmetry factor <i<(T)</i< is calculated for 94 third order basins of the Garhwal synform to decipher the tilt-block tectonics based on remote sensing and geographical information system (GIS) techniques. The quantitative analysis of the <i<AF</i< suggests that all the 94 basins are asymmetric and gentle to steeply tilted, indicating active tectonics and early and late stage of development, respectively. The mean vector magnitude (<i<θ<sub<v</sub<</i<) of <i<T</i< suggests the migration of the basin stream towards the south in most basins (60%), suggesting a unidirectional tilting of the tectonic block. The χ<sup<2</sup< test for statistical significance indicates that the <i<θ<sub<v</sub<</i< is significant for southern and northern limb basins. The χ<sup<2</sup< test affirms that the third order basin position on either side of the main channel of the river basin influences the tilt direction. The regional tectonics suggests migration of the Lansdowne klippe towards the south, as the majority of third order basins show southward tilt. The study provides a quick appraisal of tilting in the tectonic blocks of active margins, such as in the Himalayas.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield
