2006年1月1日 · Srinagar area, situated in the Garhwal Lesser Himalayas, is marked by the presence of Srinagar Thrust/North Almora Thrust (NAT). This thrust is characterized by Chandpur phyllites in hanging wall...

We integrate U–Pb zircon geochronology and 1Nd (0) values with field mapping to determine which tectonostratigraphic units are represented to the north, south and within the Almora klippe in...

1981年10月1日 · The clast petrography of the diamictites from Garhwal and the Eastern Himalaya as well as of other diamictites clearly indicates a provenance from largely Late Precambrian-Early Paleozoic rocks of the Lesser Himalaya.

Table-1 describes stratigraphy of the area. All the rocks are of Precambrian age. According to Kumar and Aggarwal (1975), the Pauri phyllite forms a formation of the Dudatoli Group and is also...

2009年9月1日 · We conducted an integrated field mapping, geochronological study, and geochemical analysis of the Lesser Himalayan Sequence strata in the Kumaun and Garwhal Himalaya of NW India (78°00′–80°30′E). Structural observations reveal a systematic change in deformation styles from lower to higher structural levels in the Main Central Thrust footwall.

outline the tectonics and to give an uniform structural picture of Garhwal and Kumaun. 2. Some remarks to Stratigraphy Work in various parts of the Himalaya showed that the stratigraphical concept of PILGRI &M WEST (1928) and AUDEN (1934) may be applied in all the Lesser Himalaya from Pakistan to Nepal (FUCHS 1967, 1974, 1975, 1976; FUCHS &

stratigraphy of the Kumaun-Garwhal thrust belt, indicate basement-involved thrusting, and document a systematic change in deformation mechanism from lower to upper structural lev-els. These results are combined with thermo-chronologic and thermometric data in a com-panion study (Célérier et al., 2009) to constrain

2024年5月27日 · U–Pb zircon depositional ages of Chandpur and Nagthat formations, Garhwal Lesser Himalaya are constrained at 900 ≤ 850 Ma (Negi et al. 2022). Nagthat Formation is dated at ~820 Ma (Hofmann et al. 2011). Based on the stratigraphic detrital zircons of the Neoproterozoic age, the Jaunsar Group is recognised at 860 Ma (Bhargava and Frank 2008 ...

2020年5月8日 · We have performed a comprehensive analysis of the results of structural geological and magnetotelluric studies along the profile across the Himalayan seismic belt in its seismic zone gap of the Garhwal segment, which has yielded a structural–lithological model of the Lesser Garhwal Himalayas section.

2023年7月20日 · High-resolution gravity data modeling reveals the crustal structure and fault geometries of Garhwal Himalaya, India. The gravity isolation technique aided the distinctive gravity signatures of the upper crustal lithotectonic boundaries. PSO fault inversions reveal the geometries and dip of the major lithotectonic boundaries.
