“…In cases where significant number of zircons have experienced Pb loss, the chemical abrasion process becomes crucial, as averages may not provide accurate results. Our study’s findings support the conclusions of Tian et al (2022) with the TuffZirc date and YMWM yielded the best results to achieve appropriate MDAs estimation when only LA-ICP-MS data is available. For this study, the LA-ICP-MS MDA methodologies such as the TuffZirc date and YMWM yielded results that were in line with CA-ID-TIMS analysis, within the margin of uncertainty.…”

“…Based on our results, the TuffZirc date and YMWM produced adequate MDA calculations when only LA-ICP-MS data is available as they yield comparable results to our CA-ID-TIMS analyses or the currently recognized biozone ages within uncertainty (Fig. 9) (Ludwig & Mundil, 2002; Tian et al 2022). In the case of sample DL7, we are uncertain whether sample DL7 associated with the Dicellograptus anceps zone at Dob’s Linn reflect Pb loss, stratigraphic misplacement, or both due to widespread tectonic and thermal activity.…”

“…9). The YMWM from Tian et al (2022) also generated appropriate results, though more robust with superior uncertainty than the TuffZirc date for two of our three samples; however, for the third problematic sample (DL7), the approach determined an MDA date 9 Ma younger than its current assessed age (Fig. 9).…”

Sedimentary rocks exposed at Dob’s Linn, Scotland, have significantly influenced our understanding of how life evolved over the Ordovician to Early Silurian. The current interpreted chronostratigraphic boundary between the Ordovician and Silurian periods is a Global Boundary Stratotype Section and Point (GSSP), calibrated to 443.8 ± 1.5 Ma (Hirnatian–Rhuddanian age), based on biostratigraphic markers, radioisotopic dates and statistical modelling. However, challenges arise due to tectonic disturbances, complex correlation issues and the lack of systematic dating in Ordovician–Silurian stratigraphic sections. Here, hundreds of zircon grains from three metabentonite ash horizons were dated using Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS). A subset of the grains were re-analyzed using Chemical Abrasion Isotope Dilution Thermal Ionization Mass Spectrometry (CA-ID-TIMS). We present a high-precision CA-ID-TIMS 238U-206Pb weighted mean date of 440.44 ± 0.55/0.56/0.72 Ma (±analytical/with tracer/with U-decay constant) for the Coronagraptus cyphus biozone. However, the study reports younger, and in certain cases, older LA-ICP-MS zircon dates within the Coronagraptus cyphus, Akidograptus ascensus and Dicellograptus anceps zones, suspected as being influenced by Pb loss and LA-ICP-MS matrix mismatch. The study reports concerns about the suitability of Dob’s Linn as a GSSP section and examines various LA-ICP-MS maximum depositional age (MDA) approaches, suggesting the use of the TuffZirc date and the youngest mode weighted mean (YMWM) as suitable MDA calculations consistent with CA-ID-TIMS results.

“…The sample obtained from the Eastern Shelf was deposited in a fluvial‐deltaic system in the Coleman Junction Formation during the late Wolfcampian time (Figure 4). Based on a recent study dating the zircons from tuffs of Wolfcamp A interval of the Permian Basin using CA‐ID‐TIMS (Tian, Fan, Victor, et al, 2022), the approximate depositional age of this sample is ca. 287–280 Ma.…”

Detrital zircon (DZ) geochronology has become a popular tool in provenance studies during the past two decades. However, similar zircon crystallization ages from different source regions greatly hamper the interpretation of sediment dispersal and recycling processes. The Alleghenian–Ouachita–Marathon (AOM) foreland and vicinity in North America is a region where some dominant DZ age groups could come from both the southern Appalachians in the eastern United States and the Gondwanan terranes in Mexico. In this study, we present 1045 new DZ U–Pb ages and 81 DZ core–rim age pairs in lower Permian sandstone in the Permian Basin and Miocene sandstone in the eastern Gulf of Mexico (GOM). These new data were integrated with published DZ single U–Pb age and core–rim ages from syn‐ to post‐orogenic strata in the Permian Basin, Marathon foldbelt, southern Appalachian foreland basin and eastern GOM to interpret the sediment‐dispersal models in the AOM foreland and eastern GOM. Our models show that during the Leonardian Stage, sediments derived from the Appalachians were first delivered to the US midcontinent and then recycled to the Permian Basin; during the Miocene, sediment from the Appalachians fluxed to the eastern GOM, with no longshore mixing from the western GOM. These models based on the integration of single U–Pb and core–rim ages are consistent with published results that used other methods, including zircon single U–Pb age, zircon Hf isotopic data, zircon (U–Th)/He age, sedimentology and stratigraphy. Our results demonstrate that although some limitations exist, zircon core–rim age is a powerful tool, adding an extra constraint on the interpretation of sediment‐dispersal systems. This tool is particularly applicable to the post‐orogenic stage, during which the sediment pathways are more complicated because of the dominant input from distal sources. Insights gained in this study imply that this novel strategy of using core and rim ages could be integrated with other methods to better understand sediment dispersal.
