“…In the past few decades, the continental crust and near-surface environment have received significant attention (Bindeman, Bekker, & Zakharov, 2016;Greber & Dauphas, 2019;Lyons et al, 2014;Taylor & McLennan, 1985). The redox state of the oceans and atmosphere through time, source composition of weathered rocks/sediments, tectonic setting, maturity, provenance, weathering history, and palaeoenvironment of the basins have been inferred using fine-grained terrigenous sediments (Basu et al, 2017;Bhatia & Crook, 1986;Liu et al, 2019;McLennan et al, 1993;Roser & Korsch, 1986;Banerji et al, 2021b).

The depositional history of the Himalayas has been overprinted by the tectonic activities during the Himalayan Orogeny. A detailed investigation of the sedimentary units can provide crucial information regarding their depositional history and provenance.This study aims at constraining the weathering history, tectonic setting, and provenance of meta-sediments from the Shimla and Chail Groups of Outer Lesser Himalaya. With similar major element chemistry, these meta-sediments comprise a low-silica group (avg. SiO 2 /Al 2 O 3 <3.29). Weathering intensity parameters chemical index of alteration (CIA), plagioclase index of alteration (PIA) and index of chemical variability (ICV) range from 62 to 78 (avg. = 69.41), 70 to 96 (avg. = 85.34), and 0.45 to 1.45 (avg. = 1.01), respectively indicating moderate to severe degrees of weathering. Transition element ratios [Cr/V (1.68-5.18), Ni/Co (1.47-30.99), and V/Ni (0.87-4.61)], and trace element bivariate plots suggest a recycled, felsic to intermediate provenance that has primarily been derived from Post-Archean sources with minor inputs from Archean units. A passive margin depositional setting with arcderived sources is suggested for the Chail and Shimla meta-sediments. Rare-earth element patterns reveal similarities between the studied metasediments with TTG gneisses and sanukitoids from the Aravalli and Bundelkhand Cratons, as well as Chaur and Jutogh granitoids. Therefore, Neoproterozoic Himalayan granitoids and ArcheanAravalli-Bundelkhand granitoids (TTGs and high-K granitoids) could be potential sources of these meta-sediments, as also suggested by the detrital zircon age distribution from the Beas-Satluj-Pabbar valleys and Shimla Group.

“…As a continuation of early climatic optimum in the Sandhyanallah Basin experienced an intense rainfall till 5 ka, gradually an increase in C 4 vegetation indicating a decreasing trend of monsoon during mid-Holocene (Sukumar et al, 1993;Rajagopalan et al, 1997) (Figure 3). High CaO and CaO/Al 2 O 3 values indicated a lagoonal and/ or estuarine conditions between 6400 and 2600 cal year BP, which later on shifted to fresh water conditions at 2600 cal yr BP (Banerji et al, 2021).…”

Holocene Monsoonal Variations Over Southern India: Looking Into Its Antecedents

A proper understanding of the paleoclimatic variability in the Southern Peninsular India demands a high-resolution paleoclimate reconstruction record. Hence, in this paper, we compiled all the available paleoclimate records from various locations across the Southern India that receives the southwest and the northeast monsoon. We delineated the southwest monsoon (SWMR) and Northeast monsoon (NEMR) variations within the Holocene Period based on the existing paleoclimatic record from this region. Paleoclimate records are primarily based on various paleoclimate archives and proxies. A detailed study of these variations unravels, (i) that SWMR gradually intensified since the younger dryas during the Early Holocene period. On the contrary, NEMR records indicate a dry phase during the same period. (ii) During the mid-late Holocene, precipitation in SWMR-dominated regions decreased, whereas precipitation in NEMR-dominated regions shows an increasing trend. (iii) Then, in the late Holocene Period, SWMR exhibits an overall wet phase with a few drier periods, and NEMR shows an intense dry period with shorter wet phases, which can be correlated to the demise of Chola dynasty, in the Southern India.

Banerji et al (2021) witnessed poor hydroclimatic conditions caused by weak monsoon during 2500-1000 BP from the geochemical proxies while conspicuous increase in the monsoon after 1000 BP which possibly led to a warm and wet climate after 1000 cal yr BP. Therefore, the fourth habitation was also perished by the flood (Ramkumar, Balasubramani, et al, 2022).…”

“…the Holocene. The majority of the paleoclimate reconstruction studies identified ISM intensification between 9 and 5 ka and inferred a general aridity trend after 4 ka (Banerji et al, 2021; Misra et al, 2019). Evidence across the world has also shown that catastrophic flood events have buried ancient habitats in floodplains (Gao et al, 2023; Sridhar, 2007; Wang et al, 2016).…”

The establishment, development and abandonment and/or destruction of ancient civilizations were catalytically controlled by geomorphic features such as lakes and rivers and the climate. This paper examined the possible influence of tectonism and climate on six habitations of the ancient Vaigai River Basin civilization in South India, using multiple proxies such as grain size, geochronology and geochemistry of the sedimentary archives. The tectonic setting of the basin changed between the active margin and passive margin; the discriminant diagrams suggested varying provenance and changing climatic conditions over the mid‐ and‐late Holocene. Tectonic activism and quiescence, base‐level change in the channel morphology led to the burial/marooning of the first habitation surface. Overall, arid conditions were punctuated with catastrophic flooding and peak discharge (flood) destroyed the second, third and fourth habitation sites. These flooding events were characterized by moderate weathering (CIA) and high values of Al, Fe and Rb/Sr and low Ca/Mg in the sediment records. The abandonment/destruction of the fifth habitation also occurred during an arid interval (droughts), possibly caused by weak monsoon. Along with the interactions between tectono‐climatic and fluvial geomorphic factors, the new results provided avenues to (a) check and recognize the archives for 8.2 and 4.2 ka‐like events in this part of the world, and (b) the utility of integrated analyses to constrain on the civilizational histories of the mankind.
