δ18O = − 4.22‰VPDB) based on multiple standard measurements of NBS-19 Aliquots of the carbonate samples were attacked with 0.5 M acetic acid in order to prevent dissolution of the siliciclastic fraction, following procedures described in21 Sr was then separated using the conventional cation exchange procedure at the Laboratory of Geochronology Samples were measured at 1250–1300 °C in dynamic multi-collection mode in a Thermoscientific Triton Plus mass spectrometer The 87Sr/86Sr values of the samples were corrected for the offset relative to the certified NIST SRM 987 value of 0.710250 The long-term (year-round) average of this standard 87Sr/86Sr ratios measured in this machine is 0.71028 ± 0.00004 Procedural blanks for Sr are less than 100 pg All uncertainties are presented at the 2σ level fifteen spots on our internal reference material Rio Maior calcite gave a low intercept age of 62.43 ± 0.37 Ma (MSWD = 0.7 This age is identical to our long-term measurement in the Department of Geology at Federal University of Ouro Preto (UFOP) Instrumental mass bias and ablation depth-dependent elemental fractionation were corrected by tying the time-resolved signal for the unknown to the identical integration window of the primary standard NIST612 BCR and BHVO were used as secondary control reference materials and yielded values within the recommended USGS range Errors are derived from the averaged counts for each mass for both the standards and values are then compared to those of the primary and secondary standards Rock samples bearing crystal fans were carefully cut out from a 5 mm thick slab with a rotating diamond blade mounted to a hand-hold hand-piece used in dental offices The material was carefully ground by hand in an agate mortar dried in an oven at 50° and then sieved into a 10–40 µm fraction We prepared three aliquots: Two fractions (A1 A2) which we processed further by subjecting them to magnetic separation using a Frantz Isodynamic separator cleaning the sample material from magnetic particles in the rock matrix and also intergrown directly with aragonite; and a third fraction (A3) which were not treated nor purified All sequentially leached samples were dried and after conversion to the chloride form with 1 mL of 6 N HCl Pb was separated on miniaturized 1 mL pipette tip columns with a fitted frit charged with 300 µL of Biorad™ AG1-X8 100–200 mesh anion resin using a conventional HCI-HBr anion exchange procedure with doubly distilled acids diluted to our needs with ultrapure water provided by a Milli-Q® Reference Water Purification System Errors assigned to the isochrons are 2σ given in the 95% confidence interval While this might indicate Pb release from at least another subordinate phase with elevated U and Th relative to Pb information deduced from the uranogenic–thorogenic common Pb diagram seems to indicate that this is unlikely the leaching patterns in this diagram reveals a linear relationship of the data with the exception of aliquot 3 (not purified by magnetic separation) A linear arrangement of TATI data in this diagram strongly supports the leaching of only one phase in this case calcite pseudomorphs after aragonite the scattered leaching pattern of A3 in the uranogenic–thorogenic common Pb diagram reflects the presence of a multicomponent system with Pb contributed from phases likely having different U/Th the well-defined correlation line defined by TATI data of the pure crystal fan separates (A1 and A2) in the uranogenic common Pb diagram is interpreted as a true mono-mineral isochron with a slope corresponding to an age of 576 ± 36 Ma (MSWD = 0.72) We interpret this age to indicate the timing of growth of the respective aragonite fans The results strongly reveal the importance of removal of matrix phases to prevent erroneous interpretation of linear arrays in uranogenic Pb isotope diagrams as isochrons whereas they instead signify mixing lines with no interpretable geological meaning recalculated for the expected age of deposition were grouped in a single column for each unit Only the less radiogenic 87Sr/86Sr results reported for each section in the cited literature corresponding to samples with higher Sr concentration and lower Mn/Sr ratios generally considered successful and accurate for low-n datasets (n < 300) but not age-equivalent to at least other two spots analytical issues or under-representation due to statistical or analytical bias and are not considered as reliable indicators of maximum depositional age All data are available within the paper and its Supplementary Material tables or from the corresponding author upon reasonable request Potentially biogenic carbon preserved in a 4.1 billion-year-old zircon Biostratigraphic and geochronologic constraints on early animal evolution Secular change in metamorphism and the onset of global plate tectonics and ultrahigh-pressure metamorphic terranes that the modern episode of subduction tectonics began in Neoproterozoic time The Neoproterozoic oxygenation event: Environmental perturbations and biogeochemical cycling The mountains that triggered the Late Neoproterozoic increase in oxygen: The Second Great Oxidation Event Did the Transgondwanan Supermountain trigger the explosive radiation of animals on Earth?
