“…Granulometric analysis is a classical tool and provides additional information regarding sediment transport, energy conditions, and depositional environment (Ahmad et al, ; Ghaznavi et al, ; Ghosh & Chatterjee, ; Kanhaiya et al, ; Srivastava & Mankar, 2009). Various textural parameters such as graphic mean, standard deviation (sorting), skewness and kurtosis have environmental significance and are useful for understanding syn‐sedimentary hydrodynamic factors of transportation and deposition in a basin (Folk & Ward, : Friedman, ; Friedman, ; Kanhaiya, Singh, Singh, Mittal, & Srivastava, ; Passega, , ; Srivastava & Mankar, ).…”

“…During the last two decades, grain‐size analyses were intensively applied by sedimentologists to determine the sediment transport pathways (Le Roux & Rojas, ; McLaren, Hill, & Bowles, ), to determine the dynamic behaviour of bottom sediments with respect to erosion, accretion, and/or dynamic equilibrium (McLaren et al, ). However, some sedimentologists still have a firm commitment to grain‐size analysis and consider it fundamental to the understanding of sedimentary processes and products (Ahmad et al, ; Cheetham, Keene, Bush, Sullivan, & Erskine, ; Ghosh & Chatterjee, ; Hartmann, ; Kanhaiya, Singh, Tripathi, Sahu, & Tiwari, ; McLaren & Bowels, ; Sengupta, ; Weltje & Prins, ).…”

Integrated approach of lithofacies and granulometric analysis of the sediments of the Proterozoic Upper Kaimur Group of Vindhyan Supergroup, Son Valley, India: Palaeo‐environmental implications

et al. 2020

Two major facies associations are identified in the Upper Kaimur Group of the Son Valley, namely, tidally influenced fluvial channel facies association and tidal sand flat association. Lithofacies supports the Dhandraul Sandstone as the product of a tidally‐influenced fluvial channel and the underlying Scarp Sandstone as a tidal sand flat, which endorse a tide‐dominated estuarine setting. Grain size analysis shows that most of the sandstone samples are medium‐ to coarse‐grained and only small fractions are of fine‐ and very fine‐grained categories. In general, sediments are moderately well sorted, near‐symmetrical to fine‐skewed and leptokurtic to mesokurtic in nature, suggesting deposition under fluctuating energy conditions in different geomorphic domains from a tidally‐influenced fluvial channel to beach settings. Bivariant plots combining the textural parameters imply that marine processes dominate over fluvial processes in the Upper Kaimur Group sediments. Cumulative curves and C–M plot suggest sediment transport mainly by saltation and bottom suspension processes under varying energy conditions.

The present study is an attempt to investigate the regional topography and drainage dynamics of the Khurar River, central India, along with the textural, mineralogical, and geochemical behaviour of the bedload sediments. The morphometric analysis was carried out using SRTM data with the help of ArcGIS 10 software. The area of the basin is 309.57 km 2 with its perimeter 83.24 km and maximum length 32.06 km. Drainage patterns are dendritic to subdendritic with stream orders ranging from first to third order. Drainage density is 0.34 per km 2 , while the bifurcation ratio is 4.5 for the river. The Khurar River Basin is an elongated basin of small size showing ENE-WSW trend analogous to the Son lineament. This basin might have originated during the Quaternary Period as a result of major tectonic activities in the region. The textural analysis indicates that the samples are bimodal to polymodal in nature ranging from very coarse to coarse grained and poorly to moderately well sorted in all the geomorphic units. The skewness value suggests coarse to fine-skewed values, while kurtosis value shows platykurtic to very leptokurtic nature of the sediments. The quartz, microcline, and albite are the chief minerals in the sediment samples with negligible variation from source to confluence of the river. The major oxide geochemistry of the sediments indicate that the dominant oxide is SiO 2 followed by Al 2 O 3 and other oxides that suggests felsic-dominated source for the sediments. The chemical index of alteration (CIA), plagioclase index of alteration (PIA), chemical index of weathering (CIW), weathering index of Parker (WIP), Vogt S. residual index (V), Ruxton ratio (R), and silica-titania index (STI) reveal moderate weathering conditions and immature nature of the sediments in the basin. These suggest that the sediments experienced a moderate amount of weathering in the river catchment under subhumid climatic conditions.

Depositional processes and sedimentation pattern in an intermontane basin: Insights from the Imphal Basin, Indo‐Myanmar Range, NE India

Intermontane basins make a distinct category of sedimentary basins, but nevertheless, the depositional processes and sedimentation patterns therein are not well understood. Quaternary sediment‐filled Imphal Basin in the Indo‐Myanmar Range provides us with an excellent opportunity of lending insight into these sedimentological aspects of an intermontane basin. Detailed facies analysis brings out that five distinct facies associations (“FAA”–“FAE”) have developed in different parts of the basin, each one of which indicates a specific subenvironment of deposition. Facies characters and spatial distribution of facies associations reveal that the basin fill records interlinked lacustrine, fluvial, and alluvial fan processes. Comprising mud and peat, the facies association “FAA” represents deposits of a lake and lakeshore swamp. The facies association “FAB” comprises mud interfingered with crudely bedded gravel and represents suspension fallout in a lake with intervening gravel‐rich, hyperconcentrated flows that diffusively plunged into the lakebed. The sand‐dominated facies association “FAC” and gravel‐dominated facies association “FAD” were deposited in fluvial domains of meandering and braided streams, respectively. Rimming the basin margin, the gravel‐dominated facies association “FAE” was deposited in the alluvial fan–interfan areas. Widespread development of the lacustrine facies (“FAA” and “FAB”) around the Loktak Lake along with extensive peat development over the lacustrine mud suggests lakeshore regression and development of vast swamps under humid conditions. The regression under humid conditions could be a result of fast and enhanced influx of finer sediments into the lake that transcended the creation of accommodation space and ultimately led to faster infilling of the lake margins favouring development of vast swamps in due course of time.
