Deep Basin Overpressure Resulting From Fluid Migration and Hydraulic Head in the Uinta Basin: Insights From Beef Calcite in the Green River Formation Alex M. Washburn, Paul J. Sylvester, Kathryn E. Snell Basin Research, 2025 Beef calcite veins in the Green River Formation of the Uinta Basin, Utah, were geochemically characterised to test two hypotheses: (1) that beef calcite veins can form during extensional tectonism and (2) that fluid overpressure can develop in open or partially restricted hydrologic systems. Laser ablation U–Pb geochronology yielded three precipitation ages, with the most precise at 24.8 ± 4.8 Ma (2σ), consistent with maximum burial of the formation and coinciding with uplift of the Uinta Basin segment of the Colorado Plateau. Clumped isotope thermometry indicates precipitation temperatures between 55°C and 72°C—substantially lower than the estimated host rock temperatures of 110°C to 140°C based on a ~30°C/km geothermal gradient. δ13C and δ18O values of beef calcite range from 1.6‰ to −1.2‰ and −10.7‰ to −11.5‰ (VPDB), respectively, with calculated δ18O of the precipitating fluid (VSMOW) ranging from −3.3‰ to −5.2‰. These values are consistent with a mixed meteoric and shallow connate water source, suggesting the downward invasion of cold, evolved meteoric fluids along faults and fractures during post‐Laramide extensional tectonic deformation. The overpressure required for beef calcite formation may have been generated by hydraulic head associated with these downward‐migrating fluids and the subsequent lateral displacement of basin brines along stratigraphic interfaces beneath regionally continuous mudstone and evaporite seals.
Bulk major and trace element abundances of barred olivine chondrules: Evidence about the physicochemical conditions in their region of nebular formation M. E. Varela, J. Roszjar, P. Sylvester, L. Garcia Meteoritics and Planetary Science, 2025 Barred olivine (BO) chondrules are present in ordinary and carbonaceous chondrites. We focus on the bulk major and trace element abundance composition of BO chondrules from carbonaceous, unequilibrated ordinary, and Rumuruti chondrites. Their bulk Fe/(FeO + MgO) wt% content versus the FeO wt% in olivine was used to divide these objects into FeO‐poor and FeO‐rich BO chondrules. The trace element content of bulk BO chondrules reveals the absence of fractionation among the abundances of elements having different geochemical behavior (e.g. Yb and [La‐Ce]). This points to the predominance of a cosmochemical (e.g. gas/liquid or gas/solid condensation) instead of a geochemical process determining their elemental abundances. In addition, their bulk trace element content provides evidence for the physicochemical conditions that prevailed in the solar nebula during their formation. In general, such nebular regions are governed by local redox variations coupled with overall falling temperatures. The bulk chemical composition of the studied BO objects (e.g., Mg/Si bulk) suggests a time scale in which FeO‐poor BO chondrules formed first in a chondrule‐forming region rich in refractory trace elements. The progressive removal of refractory phases (e.g., hibonite, fassaite, melilite) led to a nebular reservoir depleted in the very refractory elements (e.g., Zr and Y) in which the rare earth elements (REEs) tend to reach equilibrium with the chondritic reservoir. From such a reservoir, the FeO‐rich BO chondrules could have formed and were subsequently processed by metasomatic exchange reactions that equilibrated their moderately volatile V and Cr around chondritic values. The observed chemical variations are only possible if the studied BO chondrules behave as open systems exchanging elements with the cooling vapor. The inferred local redox variations coupled with overall falling temperatures could have taken place during the evolution of a single heterogeneous nebular reservoir in which Fe‐poor and FeO‐rich BO chondrules formed.
Baddeleyite SK10-3: A Natural Reference Material for Microbeam U-Pb Geochronology and Hf Isotopic Measurements Ranran Chen, Shitou Wu, Hao Wang, Martin Senger, André Navin Paul, Paul J. Sylvester, Yueheng Yang, Jinhui Yang, Fuyuan Wu Geostandards and Geoanalytical Research, 2025 Baddeleyite is an important U‐Pb geochronometer and Hf isotope tracer that commonly occurs as an accessory phase in silica‐undersaturated igneous rocks of terrestrial and extra‐terrestrial origin. Currently, very few well‐characterised, large sized reference materials are available for baddeleyite U‐Pb geochronology and Hf isotope measurement. In this study, we document a baddeleyite reference material (SK10‐3) of Cenozoic age. SK10‐3 is inclusion‐free and does not contain secondary alteration minerals. The baddeleyite has uniform U‐Pb ages and Hf isotope ratios, within analytical uncertainty, as demonstrated by multiple LA‐ICP‐MS spot analyses (weighted mean 206Pb/238U age: 31.59 ± 0.11 Ma, MSWD = 0.7, n = 197) and LA‐MC‐ICP‐MS analyses (arithmetic mean 176Hf/177Hf ratio: 0.282741 ± 59, 2s, n = 188). Seven ID‐TIMS analyses yielded a weighted mean 206Pb/238U age of 31.592 ± 0.020/0.022/0.040 Ma (n = 7, 2s, MSWD = 2.2). Nine aliquots of MC‐ICP‐MS analyses yielded an arithmetic mean 176Hf/177Hf ratio of 0.282742 ± 8 (2s). We further demonstrate that the method of shallow‐pit (~ 2 μm depth) ablation substantially improves the precision and accuracy of baddeleyite U‐Pb ages. SK10‐3 has a relatively high 176Yb/177Hf ratio (~ 0.007) compared with most other baddeleyites, allowing the precise measurement of βYb and may be useful in generating the βYb‐βHf relationship during LA‐MC‐ICP‐MS Hf isotope measurement. SK10‐3 may be a useful addition to previously distributed baddeleyite reference materials for microbeam‐based U‐Pb geochronology and Hf isotope measurements.
Thermal maximum and overpressure of the Wolfcamp formation in the Delaware Basin of Texas and New Mexico through age and temperature of beef calcite veins Alex M. Washburn, Paul J. Sylvester, Zsófia Poros, Kathryn E. Snell AAPG Bulletin, 2024 Two unresolved issues in the history of the Delaware Basin of western Texas and southeastern New Mexico are (1) whether basin-elevated thermal maturities of organic matter resulted from elevated paleogeothermal gradients or deeper burial and (2) the timing of pore fluid overpressure development in the Wolfcamp formation. These unresolved issues are explored through the application of U-Pb geochronology and clumped isotope thermometry of beef calcite veins taken from the Wolfcamp formation of the Delaware Basin. The age of the beef calcite is constrained by one successful U-Pb discordia of 152.9 ± 53.1 Ma (mean squared weighted deviation = 1.2), with attempted ages in samples resulting in prohibitively large errors due to high common lead and low uranium. The temperature of Wolfcamp beef calcites by clumped isotope (Δ47) thermometry ranges from ∼142°C to 162°C. Consistency between beef calcite temperature and interpreted organic maturity of fluid inclusions in beef calcite veins precludes solid-state reordering of the Δ47 thermometer. Consistency between beef calcite temperature and organic thermal maturity by pyrolysis indicates vein precipitation at basin thermal maximum. A one-dimensional burial history constrained by beef calcite age, temperature, and apatite fission-track analysis data is proposed that indicates a higher-than-present-day geothermal gradient (30°C/km) and deeper burial (∼1.8 km) during the Mesozoic. Because beef calcite samples were taken from presently overpressured intervals of the Wolfcamp formation and are thought to form in the presence of high overpressure, overpressure likely preceded beef calcite precipitation and persisted through to the present day.
Paleoproterozoic A-Type Postcollisional Granitic Magmatism Associated with the Arrowsmith Orogeny during the Global Tectonomagmatic Lull C. A. Partin, P. J. Sylvester Journal of Geology, 2023 The tectonomagmatic history of the early Paleoproterozoic (Siderian) global tectonomagmatic lull (TML; ca. 2.4–2.2 Ga) is poorly known, limiting understanding of lithospheric processes during the Archean to Proterozoic transition. In this study, we identify and describe an unusual ca. 2.4–2.3 Ga postcollisional A-type granite suite associated with orogenic collapse of a continental collision in the middle of the TML. The postcollisional A-type granitoids consist of monzogranite to tonalite intrusions of the North Shore plutonic suite, emplaced during the middle and later stages of the ca. 2.5–2.3 Ga Arrowsmith orogeny, which represents a long-lived accretionary orogen on the northwestern margin of the Archean Rae craton in northern Canada. New laser ablation (LA)-ICP-MS U-Pb zircon age data indicate that the North Shore plutonic suite represents protracted granitic magmatism over ca. 70 My. The new U-Pb ages combined with previous and new LA-MC-ICP-MS Hf isotope and secondary-ion mass spectrometry O isotope zircon data reveal compositional heterogeneities not previously recorded by bulk isotopic methods and require changes to the classification of the granitoids and their role in the Arrowsmith orogeny. Zircon εHf values of the North Shore plutons are consistent with a mixture of juvenile and older crustal components in their sources, but their nonenriched zircon δ18O values are inconsistent with a large supracrustal melt component, precluding an S-type granite parentage. Instead, their trace-element proportions in discrimination diagrams and zircon δ18O values show A-type granite affinities, which are often missed in studies of ancient, poorly defined orogens. Aluminous compositions of the A-type granites are compatible with emplacement in a continent-continent collision, following postcollisional slab break-off and delamination. Postcollisional emplacement of the A-type granites is consistent with other geologic evidence suggesting that subduction beneath the Rae craton margin ceased by 2.4 Ga.
Significance of U-Pb detrital zircon geochronology for mudstone provenance Paul J. Sylvester, A. Kate Souders, Rui Liu Geology, 2022 Detrital zircon U-Pb studies of mudstone provenance are rare but may preferentially fingerprint distal zircon sources. To examine this issue, Pierre Shale and Trinidad Sandstone deposited in a Late Cretaceous deltaic environment in the Raton Basin, Colorado (USA), were measured for detrital zircon U-Pb age by laser ablation–inductively coupled plasma–mass spectrometry. Two major detrital zircon age peaks at ca. 70 and 1690 Ma are found in both Pierre Shale and Trinidad Sandstone but in inversely varying proportions: 68% and 16%, respectively, for the finest zircon fraction (~15–35 μm) in the shale, and 25% and 32%, respectively, for the coarsest zircon fraction (~60–80 μm) in the sandstone. Proximal sources in the Sangre de Cristo Mountains, directly west of the Raton Basin, contain coarse-grained, ca. 1690 Ma zircon, whereas distal sources in Laramide uplifts and basins in Colorado, New Mexico, and Arizona contain fine-grained, ca. 70 Ma zircon. The results indicate that U-Pb zircon provenance of mudstone reflects availability of volcanic and other fine-grained source rocks rather than simply distal sources. U-Pb zircon provenance studies should routinely include mudstone units because these units may identify fine-grained zircon sources more reliably than sandstones alone.
The Cretaceous-Paleogene contact in the Tornillo Group of Big Bend National Park, West Texas, USA Thomas M. Lehman, Jacob Cobb, Paul Sylvester, A. Kate Souders Geosphere, 2022 The Cretaceous-Paleogene (K-Pg) contact interval is constrained by vertebrate fossil sites at seven sites in the Tornillo Group and lies within an 80–100-m stratigraphic section between the top of the Javelina Formation and the base of the “log jam sandstone” marker bed in the Black Peaks Formation. In western exposures of this interval, the highest occurrence of in situ dinosaur specimens and the lowest occurrence of Paleocene mammal specimens are separated by an unusual conglomerate bed. This thin conglomerate bed coincides with the contact between Cretaceous and Paleogene strata and contains reworked Cretaceous fossils. It is superficially similar to conglomerate beds elsewhere attributed to the effects of tsunamis generated by the Chicxulub impact; however, the maximum depositional age of ca. 63 Ma based on detrital zircons indicates that the conglomerate was deposited about three million years after the K-Pg boundary event. Paleocene mammalian fossils from immediately above the conglomerate bed represent a fauna that can be no older than the middle Torrejonian (To2 interval zone). The contact between Cretaceous and Paleocene strata is therefore disconformal and represents a hiatus of at least three million years. A condensed section occurs at the westernmost exposure of the K-Pg contact, where at least 80 m of strata are absent below the conglomerate bed; these strata are present in exposures farther east. This condensed section likely records an erosional event resulting from uplift and deformation of the nearby Terlingua monocline. Although the 80 m of strata below the conglomerate bed are poorly fossiliferous, several clearly in situ dinosaur specimens indicate that this entire interval is Late Cretaceous in age. There is no compelling evidence for preservation of the K-Pg boundary event horizon at any of the seven sites in the Tornillo Group, and so the hiatus represented at the Cretaceous/Paleocene contact here likely also includes some part of latest Cretaceous time. Mammalian specimens from sites in the “log jam sandstone,” ~40 m above the middle Torrejonian sites, represent an early Tiffanian fauna (Ti1 interval zone). Latest Torrejonian (To3) sites have not been recognized, and therefore a second disconformity likely coincides with the base of the “log jam sandstone” marker horizon in the Black Peaks Formation.
