“…4b-d) are notably depleted (mean = 0.708038, n = 19, Cui et al, 2016;Vishnevskaya et al, 2017Vishnevskaya et al, , 2013 relative to all screened data prior to the nadir in upper Cambrian Stage 2 (Table S2). Recent efforts to produce a global late Ediacaran 87 Sr/ 86 Sr compilation suggest that the low 87 Sr/ 86 Sr data recorded by the Khatyspyt Formation are supportive of a temporal placement approximately coincident with and postdating data from the Nama Group (Cui et al, 2020a). Potential issues with this correlation are outlined below.…”

“…The inverse linear trend between Nd and Sr isotope compositions reflects the general relationship present in crustal rocks and materials (Allègre, 2008; Allègre et al., 1979; DePaolo, 1988). Consequently, in most situations, ε Nd values are also negatively correlated with Sr isotope ratios in juvenile and hydrothermal waters (Cui et al., 2020; Jakubowicz et al., 2019, 2020; Négrel et al., 2000) and groundwaters (e.g., Nakano, 2016; Négrel & Petelet‐Giraud, 2010; Tricca et al., 1999).…”

Over the past decades, neodymium (Nd) isotopes have received considerable attention in paleoceanography as a tool for reconstructing past seawater circulation, local weathering inputs, and sea‐level change. In this study, we have investigated the Nd isotope composition of a shallow‐water Serpukhovian (Carboniferous) carbonate succession to explore icehouse cyclicity pattern and seawater dynamics on the Karatau carbonate platform in southern Kazakhstan. The cyclic succession formed in response to glacio‐eustasy and composed of subtidal and intertidal limestones displays a large variation in εNd(326 Ma) values from −1.6 to +4.3, corresponding to differences in the isotopic composition of two seawater masses present in the Uralian–Turkestan Ocean during the Serpukhovian: (a) highly radiogenic deep waters and (b) less radiogenic surface waters. The Nd isotope excursions within the icehouse cycles are more complex than simple transgressive‐regressive cycles. They probably reflect a temporal pattern of the sub‐Milankovitch climatic perturbations during Carboniferous interglacial intervals. The episodic appearance of rich brachiopod communities was forced by the inflow of highly radiogenic, nutrient‐enriched waters, presumably driven by upwelling. Nd isotope analyses of cyclic intertidal and subtidal carbonates have great potential to produce high‐resolution records of seawater dynamics on shallow‐water carbonate platforms.
