Evolution of a Neogene fluvial system in a Himalayan foreland basin, India

Rock magnetic characterization of pedogenesis under high energy depositional conditions: A case study from the Mio–Pliocene Siwalik fluvial sequence near Dehra Dun, NW Himalaya, India

“…The entire sequence represents relative variation of distal to proximal fan setting in an overall proximal setup (Kumar, 1993;Kumar and Ghosh, 1994;. Reconstruction of magnetic polarity stratigraphy by Sangode et al (1999) infer an age of 9.73-4.86 Ma for the studied section ( Fig.…”

“…Detailed sedimentologic attempts in the MR section infer a predominance of fine to coarse grained grey multistorey sandstones representing braided streams with frequent avulsion and sheet flood events in a sandy alluvial fan regime (Kumar, 1993;Kumar and Ghosh, 1994;Kumar et al, 2004). The entire sequence represents relative variation of distal to proximal fan setting in an overall proximal setup (Kumar, 1993;Kumar and Ghosh, 1994;.…”

Hydrochemical evaluation of shallow groundwater aquifers: a case study from a semiarid Himalayan foothill river basin, northwest India

“…The headwater region is covered by sandstones, conglomerates, limestones, claystones, mudstones, shales and siltstones of Paleocene to Pliocene age of the Siwalik Group. These rocks represent thick continental molasse deposits in the Himalayan foreland basin (Prakash et al 1980;Kumar et al 1996Kumar et al , 1999. The alluvium deposit is composed of clay, silt, sand and gravel of Pleistocene to Recent age.…”

Sedimentology of the Essaouira Basin (Meskala Field) in context of regional sediment distribution patterns during upper Triassic pluvial events

“…No clear erosive bases or higher angle crossbed sets which would point to deep, confined channels were recognised, and deposition in a non-confined braided river system is inferred (Miall, 1977(Miall, , 1996(Miall, , 2006Bridge, 1993;Bridge, 2003Bridge, , 2006. Occasional interbedded thin mudstone horizons that cap these well sorted sandstones are interpreted to be genetically linked and record deposition from suspension during low-energy flow conditions of waning flow (Miall, 1977;Turnbridge, 1981;Kumar et al, 1999;Newell et al, 1999;Platt & Keller, 1992;Owens et al, 1999;Bridge, 2003Bridge, , 2006. Massive sandstones defined by prominent destratification and minor remnant faint patchy lamination often associated with these deposits, are hence interpreted to represent post-depositional modification and dewatering during abandonment.…”

“…The upward-fining sandstone units are interpreted to represent fluvial channels (sub-facies 2b) within an extensive floodplain environment (subfacies 2a) (e.g. Miall, 1995; Nanson & Croke, 1992; Kumar et al, 1999;Newell et al, 1999;Colombera et al, 2015). The intercalated very fine-grained sandstone deposits are up to 4 m thick, and are suggested to represent both amalgamated sheet-like sandstone elements, and more confined (crevasse) channel deposits (Nanson et al, 1986;Miall, 1996;Bristow et al, 1999;Bridge, 2003;Medici et al, 2015).…”
