Abstract: The Dry River Diorite is one of the few mafic bodies spatially associated with the White Mountain Batholith of New Hampshire, USA. However, new U–Pb zircon geochronology reveals a 119.92 ± 0.62 Ma emplacement age for the diorite, considerably younger than the ca. 200–180 Ma batholith and indicates that it is instead a member of the younger White Mountain Magma Series (ca. 130–100 Ma) of the New England–Quebec province. The diorite is mildly silica undersaturated, with chondrite-normalized REE and spider diagram patterns that indicate ocean island basalt compositions. Several tectonic discrimination diagrams indicate the magmas have within-plate basaltic compositions. Ce/Yb versus La/Ta and Sm/Yb versus La/Sm values indicate the magmas are 2–5% partial melts of garnet peridotites. ƐNd and initial 87Sr/86Sr values range between 4.27 to 3.44 and 0.7036 to 0.7040 respectively. All these geochemical characteristics are identical to those of the mafic rocks of eastern Monteregian Hills and the Ossipee complex basalts of central New Hampshire. Modeling of the Dry River Diorite as the mafic endmember of the felsic rocks of the younger White Mountain Magma Series indicates that the felsic rocks contain up to 50% crustal endmember.
Previous high-precision geochronological studies indicated a relatively brief period of magmatism across this region and have argued that observed age progressions of continental magmatism are consistent with the Great Meteor Hotspot hypothesis for their formation. The age produce here for the Dry River Diorite is consistent with this trend’ however, the younger-than-predicted age is likely the result of Pb-loss or complex geological factors. Although the Cretaceous magmatic rocks in this region do not easily fit a linear age progression as a simple hotspot model might predict, the confluence of geodynamic processes that have shaped this region over 200 myr are not simple and require a high standard of verification for any one hypothesis. Whether these magmas resulted from complex hotspot dynamics, asthenospheric upwelling, or some other mechanism or combination of mechanisms requires a clear path to deconvolve the role each process had in shaping the magmatic history we can now observe. The new geochronologic data we present is consistent with other ca. 120 Ma, geographically proximal plutons in the region and therefore consistent with the age progression a hot spot model would predict for a large fraction of the Cretaceous magmatism observed across the region; however this does not preclude other models, e.g., edge-driven convection, for parsimoniously explaining magmatism in the region that does not conform to this track

Automation Accelerated screening of H-Bond-Rich Iridium Photosensitisers for Hydrogen Generation
No full textwe demonstrate the incorporation of a series of our H-bond rich guanidine-styled iridium (III) complexes into a catalytic system. Using automation accelerated catalysis screening techniques we optimised our system quickly and effectively to observe how these strongly H-bonding complexes may perform. Proven to be photo-electronically suitable, and with effective electron transfer abilities evidenced by Stern-Volmer mechanistic studies, the complexes showed modest levels of H2 evolution in comparison to previously investigated photosensitisers with general formula [Ir(C^N)2(N^N)]

Abstract: A narrow (<1 m) fine- to medium-grained lamprophyre dyke intruded Neoproterozoic monzodiorite on the eastern side of Machias Seal Island in the northern Gulf of Maine about 19 km southwest of the island of Grand Manan, New Brunswick, Canada. The dyke is near-vertical and trends 015° to 025°, with two shoreline exposures about 680 m apart assumed to be the same dyke. The dyke is notably dark and dense, with a granular broken surface. Thin sections reveal abundant euhedral outlines of olivine pseudomorphs in a groundmass of small (<0.2 mm) grains of brown amphibole (kaersutite) and augite, with ocelli and interstitial patches of albite, calcite, and analcite. The olivine phenocrysts have been completely replaced by chlorite, whereas other ferromagnesian minerals remain unaltered. Accessory minerals include abundant needle-shaped apatite, magnetite, and cubic pyrite. Another small dyke on the western side of the island is less mafic, non-porphyritic, and consists of fine- to medium-grained plagioclase and clinopyroxene, which are highly altered; we interpret it to be unrelated to the lamprophyre dyke to the east. Whole-rock chemistry shows that the lamprophyre dyke is camptonite, similar to some Mesozoic lamprophyre dykes of Maritime Canada and New England, USA, of which the nearest example is about 110 km to the southwest in coastal Maine. Laser fusion 40Ar/39Ar analyses of single kaersutite crystals (n = 12) yield an age distribution with a single, well-defined mode of ca. 468 Ma; incremental heating analyses of small aliquots of crystals show evidence of some radiogenic 40Ar loss and yield a mean plateau age of 478.7 ± 1.9 Ma. This Early Ordovician age and the accompanying uncertainty are interpreted to represent the time of crystallization for the camptonite dyke. The camptonite of Machias Seal Island is older than other Paleozoic and Mesozoic mafic dykes in the region. It is interpreted to be the product of partial melting of a metasomatised mantle during the Penobscot orogeny
Supplementary Data Files to accompany: "U-Pb, Lu-Hf, and trace element zircon data from plutonic rocks of the New England Avalon terrane, USA." (Kuiper, Y.D., Murray, D.P., and Crowley, J.L., 2025)
No full textNew zircon U–Pb, Lu–Hf and trace element laser ablation inductively coupled mass spectrometry (LA-ICP-MS) data are presented for ten Ediacaran granitoid samples from the New England Avalon terrane, and from possibly exotic blocks of southeastern Massachusetts and Rhode Island, USA. Crystallization ages of the analyzed samples are ca. 611–577 Ma, with nine samples between ca. 611 Ma and ca. 588 Ma. These overlap with previously published ca. 620–589 Ma ages of granitoid rocks and ca. 597–584 Ma ages of volcanic complexes in the northern part of the terrane, where volcanism occurred immediately after plutonism. A granite that cuts sedimentary and volcanic rocks with a previously determined maximum depositional age of ca. 613 Ma in southern Rhode Island yielded a zircon chemical abrasion isotope dilution thermal ionization mass spectrometry (CA-TIMS) date of 609.30 ± 0.22 Ma. Volcanism therefore occurred between ca. 613 Ma and ca. 609 Ma, and ca. 10 myr prior to that in the northern part of the New England Avalon terrane. This area may be part of the previously interpreted exotic Newport Block.
Zircon εHf(t) values of all samples are -2.8–6.0, with ca. 1.23–0.96 Ga TDM1 Hf model ages. These values are also consistent with published εHf(t) values between -3.1 and 5.9 of nine published plutonic and volcanic rocks. Zircon trace element geochemistry data show mostly mixed continental arc and oceanic island signatures. The Eu/Eu* values are mostly 0.1–0.7, suggesting ~30–80 km crustal thicknesses. The exception is a sample southeast of the Nauset magnetic anomaly on the southeastern tip of Massachusetts, which has the highest zircon ∑REE values, mostly Nb/Hf >0.001, generally low Eu/Eu* values, and high εHf(t) values, all suggestive of a within-plate/anorogenic/rift setting. The new data provide a valuable reference data set, guiding future studies on the New England Avalon terrane and/or adjacent exotic blocks and on similar crustal domains elsewhere

Physiological Indicators of Mental Workload in Long-Term Care Simulation
No full textThis data was collected to answer the research question of how time, pressure from superiors, and behavioural and psychological symptoms of dementia influence the mental workload experienced by care aides while delivering daily care. Data was collected at the UNB Long-Term Care Research Simulation Lab between May to August 2024. The data includes non-identifying demographic data about the participants as well as two measures of physiological data collected during a simulated care scenario. The first physiological measure is heart rate variability (HRV) measured using FirstBeat Bodyguard 3 monitor and adhesive electrodes. The second physiological measure is pupil diameter measured using 3D pupil models produced by PupilLabs Core glasses
