Recognising different sediment provenances within a passive margin setting: Towards characterising a sediment source to the west of the British late Carboniferous sedimentary basins

Sources of clastic material of the Neoproterozoic metasedimentary rocks of the Baikal–Patom belt, Northern Transbaikalia: Evidence from Sm-Nd isotope data

“…The rocks are heterogeneous in terms of 147 Sm/ 144 Nd ratio. Obtained 147 Sm/ 144 Nd ratios vary between 0.08 and 0.14, which in general is typical of sedimentary rocks formed in a sea basin in a passive continental margin setting (Diskin et al, 2011). The measured 143 Nd/ 144 Nd ratio varies within 0.5112-0.5122.…”

“…Most of them are ascribed to highly siliceous rocks, with SiO 2 content more than 63 wt % (Diskin et al, 2011) (Table 1). Exceptions are the rocks with high carbonate content (SiO 2 < 41 wt %), which is marked by the elevated CaO (up to 40 wt %) and significant loss on ignition (up to 25 wt %).…”

Provenance and depositional setting of Lower Silurian siliciclastic rocks on Hainan Island, South China: Implications for a passive margin environment of South China in Gondwana

“…Consequently, the chemical and isotopic components of sedimentary rocks can be used to distinguish the sedimentary environment and tectonic setting, even the tectonic evolution of the source area and the formation of the early earth's crust (e.g., McLennan et al, 1995;Ghosh and Sarkar, 2010;Diskin et al, 2011;Tao et al, 2014;Wang and Zhou, 2014).…”

“…The petrography, mineralogy and the whole-rock geochemistry (major-and trace elements, and Sr-Nd isotopes) of (meta)clasticsedimentary rocks have been widely used to determine provenance of source areas, to evaluate the nature of paleoweathering in the source region, and to constrain the tectonic setting and nature of depositional basins, and thereby to understand the evolution of continents (e.g., Nesbitt and Young, 1984;Taylor and McLennan, 1985;Bhatia and Crook, 1986;Roser and Korsch, 1986;McLennan et al, 1990McLennan et al, , 1993McLennan et al, , 1995Fedo et al, 1995;Gu et al, 2002;Mader and Neubauer, 2004;Xu et al, 2007b;Diskin et al, 2011;Wang et al, 2013b;Tao et al, 2014). The age distribution of detrital zircon populations in (meta)sedimentary successions has also been successfully used as a powerful proxy to constrain the provenance characteristics of clastic sediments, to test or clarify the affiliation of different blocks or microcontinents, and thereby to unravel the tectonic histories and paleogeographical reconstructions of paleocontinents or terranes, which is a key component of research into geodynamics of basin formation and orogenic processes (e.g., Gerdes and Zeh, 2006;Wang et al, 2007Wang et al, , 2010Wang et al, , 2012bCondie et al, 2009;Yu et al, 2010;Cawood et al, 2013a,b;Li et al, 2013;Zhang et al, 2014).…”

Characterisation of archaeological ceramics from the Khwebe Hills of northern Botswana

“…In geological studies, the significance of sediment geochemistry in elucidating the provenance of sedimentary suites, their evolution, and source weathering is well established (Bhatia, 1983;McLennan et al, 1990, Condie et al, 2001, Huntsman-Mapila et al, 2009, Diskin et al, 2011. The use of major (e.g.…”
