“…Interpretation: The colour of the intercalated sandstone and siltstone unit is evidence of subaerial exposure and a low water table in a predominantly oxidizing environment (Walker 1967;Abdul Aziz et al 2003;Spalletti and Pinol 2005). Horizontally stratified sandstone (Sh) is interpreted as evidence of high energy flow (i.e., upper plane bed), probably associated with flooding events (Miall 1977;Khalifa et al 2006;Türkmen et al 2007). Cross-stratified facies (i.e., Sx, Sp, and St) commonly indicate the waning stage of flooding and decreasing velocity of flows towards lower flow regime conditions (Spalletti and Pinol 2005;Khalifa et al 2006;Hadlari et al 2006).…”

“…The small core diameter and many core breaks at the contact between sandstone and mudstone preclude confirmation of downcutting and channelization (i.e., fluvial flow). Although coarsening-upward profiles could represent, for example, prograding fan lobes, crevasse splays, or avulsion belts, they can also be related to base-level changes (Türkmen et al 2007). Collectively this association of sandstone and intercalated siltstone favours a braidplain or distal alluvial fan setting.…”

The area around Penobsquis, east of Sussex, New Brunswick, Canada, is an important location of natural resources for the province. The McCully gas field produces from strata of the Mississippian Horton Group whereas younger strata of the Windsor Group are host to major potash and rocksalt deposits. Overlying these units are over 1 km of poorly understood red beds currently assigned to the Mississippian Mabou Group. To date, this latter unit lacks significant marker beds and has had no useful biostratigraphic recovery, despite recent extraction of close to 5 km of drill core. Research on this core broadly identifies siltstone and sandstone at the base of the Mabou Group that gradually coarsen up into conglomerate. The succession is considered the result of alluvial-fan progradation from the northeast. Within this succession, in several of the cores, is a single interval of localized, horizontally laminated to cross-stratified, bluish-grey sandstone, containing carbonaceous plant fragments and siltstone intraclasts. To assess the importance of this interval in the context of the red bed succession, a total of 131 samples of core from three boreholes have been analyzed using Inductively Coupled Plasma and spectroscopic techniques to determine chemostratigraphy. Study of various elemental ratios can delineate two packages, one that corresponds to the grey interval and overlying red beds, and the other to the underlying red beds. Changes in the elemental ratios are interpreted to mark a broader population of mineral species related to greater variation of provenance and diagenesis in the upper sediment package. The reduced horizons and rip-up clasts may have been produced by sediment reworking along a boundary that represents an unconformity (in core, a disconformity) at a stratigraphic level near to where one has been inferred by other workers.

“…Arslantepe is situated in the south‐easternmost part of the Malatya Plain in Eastern Anatolia, 15 km south‐west of the Euphrates River and north of the Antitaurus Mountains. The Malatya Plain is located in a large fault‐boundary continental basin formed during the Neogene in response to strike–slip and extensional regimes (Şaroğlu and Güner ; Şengör et al ; Şaroğlu and Yılmaz ; Önal ; Önal and Kaya ; Türkmen et al ) and spreading over 800 km 2 , which contains an Upper Cretaceous to Tertiary sedimentary succession up to 700 m thick. The fill of the basin can be subdivided into three main sequences (the Gündüzbey group, the Beylerderesi formation and the Yeşilyurt group), alternating fluvial, alluvial, shallow‐ and deep‐marine environments (Önal and Kaya ).…”

The petrographic and geochemical analyses of 130 Late Chalcolithic 3 (LC3, 3800 bce) to Early Bronze Age IIIB (EBAIIIB, 2000 bce) ceramics from Arslantepe and the Malatya Plain in the Eastern Anatolian Upper Euphrates have identified critical differences in raw material procurement and paste preparation, reflecting typological, chronological and cultural changes. Based on these differences, distinct modes of production that correspond to phases reflecting significant social, economic and political changes were recognized. In particular, the interruption of the centralization process and the establishment of mobile groups during EBAI (3000–2900 bce) were accompanied by the exploitation of new sources.

“…The paleoclimate of the early Cretaceous Luanping Basin was mainly semiarid and humid (Li, Song, Zou, Wang, & Ji, 2008;Ohta et al, 2011). Despite the low precipitation in semiarid regions, they are likely to undergo extensive flood events that are caused by the high discharge variability under severe climate change (Dill, Khishigsuren, Bulgamaa, Bolorma, & Melcher, 2006;Long, 2017;Türkmen, Aksoy, & Taşgin, 2007;Zaman, Rahman, & Haddad, 2012). Thus, the paleoclimate was favourable for the development of hyperpycnal flows.…”

Hyperpycnites are extrabasinal turbidites related to hyperpycnal flows which form during river floods. Compared to intrabasinal turbidite systems in deep marine or lacustrine settings, hyperpycnites in shallow lakes settings are not understood. In this work, we studied the typical sedimentary characteristics of shallow lacustrine hyperpycnal flow deposits in outcrops of the Luanping Basin, Northeast China. Based on the sedimentary architecture and analysis of the facies associations in these outcrops, the hyperpycnites can be classified into the following three types: (a) bedload-dominated erosional channel deposits, (b) bedload-and suspended-loaddominated channel-to-lobe transitional deposits, and (c) suspended-load-dominated lobe deposits. The erosional channels in proximal locations are filled by mud clasts, parallel-laminated sandstones, massive sandstones, cross-bedded sandstones, massive siltstones, and mudstones. The channel-to-lobe transitional deposits in a middle location are composed of parallel-laminated sandstones, cross-bedded sandstones, mud clasts near internal erosional surfaces, ripple cross-bedded sandstones, massive siltstones, and mudstones. The lobe deposits in distal locations are composed of ripple cross-bedded sandstones, massive siltstones, and mudstones. The sedimentary process of the shallow lacustrine hyperpycnal flows shows obvious response to periodic flood energy fluctuations. Gentle slope, small capacity of flood discharges and semiarid paleoclimate may be the possible reason for the observed sedimentary architecture of the shallow lacustrine hyperpycnal flow deposits. Therefore, this study
