The classification of the sediments into facies and the various environments in which the sediments of the northeastern Voltaian basin were deposited has not been clearly described. Using detailed field mapping together with petrographic studies, six sedimentary facies has been identified; F1 is defined by asymmetric wave formed ripple marks, F2 indicates flute casts on micaceous sandy shales, F3 has bifurcated ripple and climbing ripple marks on argillaceous materials at the middle parts of the scarp, F4 is identified by parallel and cross stratifications observed close to the upper parts of the scarp, F5 has a bipolar herringbone cross beds and planar cross beds on quartz rich sediments at the southern parts of the study area and a distinctive well developed burrows (Skolithos) at the southern half of the study area defines facies F6. The sediments are deposited largely in a shallow marine environment, with subordinate fluvial, flood plain, deltaic, aeolian, tidal flats and shoreface/nearshore environments. Although, there exist a suitable depositional environment for the formation of hydrocarbons, the overlying sediments are not thick enough to give the required temperature and pressure conditions for hydrocarbons development in the northeastern fringes of the basin. Paleosol features evident by pseudokarren, like weathering marking the contact between the middle Oti/Pendjari group and the lower Gambaga group of the study area. The sequence of the area is that of a typical shallowing, thickening and coarsening upward sequence.

“…The overall fining upward nature of the sandy basal succession suggests a progressive decline in the wave and current competency from the lower to the upper part of the succession (e.g. Zakir Hossain et al 2002). In the higher up, the shales containing diverse variety of fauna were deposited in protected lagoons (Fig.…”

The Paleocene-Eocene succession of the Jaisalmer area has hydrocarbon potential. This succession is dominantly represented by calcareous and argillaceous rocks with a subordinate proportion of arenites in the basal part. This succession is subjected for facies analysis using field characteristics coupled with petrography and we attempt to establish depositional environments based on facies analysis. A total of eight lithofacies are identified; those are cross-bedded sandstone, thinly bedded sandstone, laminated sandstone, yellow calcareous shale, chalky limestone, fossiliferous shale, fossiliferous limestone and nodular limestone. The upper Paleocene sandstones were deposited in shoreface to foreshore zones on barrier margins of a ramp/platform. The overlying lower Eocene to middle Eocene sequences containing limestone-shale alternation suggests their deposition in lagoons and tidal flats. The occurrence of ooids and peloids and diverse genera of larger foraminifera demonstrates that the deposition of carbonates took place in a tropical climatic condition. The facies associations suggest a complete 2nd order cycle of transgression-regression of the sea from shoreface to tidal flat in the Jaisalmer pericartonic basin.

“…Miall 1992;1996;Mazumder 2002;Zielinski and van Loon 1999b). The S2 facies indicates deposition in a high-energy setting of proximal-fan as characterised by coarse sand, pebbles at channel bases (cf., Zielinski and van Loon 1999a;Zakir Hossain et al 2002;Kundu et al 2012) or in mad-fan setup with coalescing or interlacing channels (Opluštil et al 2005). Sheet sand geometry without any channelised deposit and absence of any other primary structure in S3 facies units together point to waning energy flood deposits possibly in distal fans (e.g., Zavala 2008;MacCarthy 1990;Sadler and Kelly 1993).…”

A petrography-geochemistry-based evaluation of the provenance of the sandstones of the Tertiary Middle Siwalik Subgroup in the Lish River Valley, West Bengal, is presented. The framework grains in the sandstones suggest mixing of sediments from spatially separated gneissic, quartzitic and phyllitic source rocks. Modal values of different framework minerals suggest that recycled sediments in an orogenic setting were deposited in the Middle Siwalik basin in the area. The major and trace element ratios suggest dominantly felsic input and mixing with subordinate basic material in an upper continental crustal setup. The major and trace element data also indicate that rocks of a passive margin setting acted as the source to the sediments. The present paper postulates that the Middle Siwalik sediments were derived from pre-Himalayan gneissic and metabasic rocks of an erstwhile passive margin setting and presently forming the Higher and Lesser Himalaya, respectively. basin.
