title: Detrital zircon geochronologic dataset of Late Mississippian to Middle Pennsylvanian sediment, southwestern Kansas and northwestern Arkansas

description: We report 1544 new concordant ages, 582 ages from Kansas core and 962 ages from Arkansas outcrop samples. U-Pb age spectra are characterized by major Grenville (900–1,300 Ma) and Taconic-Acadian (350–500 Ma) age clusters and minor components of older age groups, suggesting a persistent source in the Appalachians tied to the Alleghanian orogeny. However, by the Early Pennsylvanian, the Hugoton Embayment samples see the Appalachian source partially replaced by Yavapai-Mazatzal (1800–1600 Ma) and Granite-Rhyolite (1550–1300 Ma) grains, major components of the local basement, that suggest contributions from nearby ARM uplifts.

title: Late Holocene Sr-Nd isotope and REE data from the Siple Dome ice core, Antarctica

description: Compositions of mineral dust in ice cores serve as tracers of paleo-atmospheric circulation patterns, providing linkages between sources and sinks. To determine the source(s) of dust to Siple Dome, Antarctica, we measured Sr-Nd isotope ratios and REE concentrations on late Holocene samples (~1030-1800 C.E.) from the Siple Dome A deep ice core. We also measured Sr-Nd isotope ratios of dust from the Clark Glacier ice core, Dry Valleys, to compare dust compositions from the eastern and western shores of Ross Sea embayment. Siple Dome data are characterized by low Nd isotope ratios (as low as εNd = -16.3) along with low Sr isotope ratios (highest 87Sr/86Sr = 0.7102) compared with other Antarctic dust signatures. A well-defined inverse correlation between Sr-Nd isotope ratios indicates two primary mixing sources. Siple Dome dust compositions are distinct from dust deposited on Taylor and Clark Glaciers in the McMurdo Dry Valleys of the western Ross Sea, precluding the Dry Valleys as a late Holocene dust source to this region of the eastern Ross Sea.

title: Sr-Nd-Pb-Hf-Os isotopic ratios for Quaternary basalts and Precambrian Granitoid-Gneiss from the Itasy Volcanic Field (IVF), Madagascar.

description: We present new major and trace element and Sr, Nd, Pb, Hf, and Os isotope data for Quaternary basaltic lavas and tephra from the Itasy volcanic field, in order to assess the origin and sources of recent volcanism in the central highlands of Madagascar. Our age determinations provide further evidence for Pleistocene volcanism on the island, with ages between 31 and 104 ka. Mafic magmas from Itasy exhibit significant geochemical heterogeneity, and they are chemically distinct from those of the neighboring Ankaratra volcanic complex. Trace element signatures of the Itasy volcanic field are very similar to those of ocean island basalts (OIB), with significant enrichment in high field strength elements (e.g. Nb and Ta) and depletion in large ion lithophile elements (e.g. Rb, Cs, and K), and relatively high Nb/U (&gt;45) and Ce/Pb (&gt;25) ratios. Significant intra-volcanic field isotopic heterogeneity is observed, with well-defined negative correlations of 87Sr/86Sr with 206Pb/204Pb and 143Nd/144Nd. These correlations, along with highly radiogenic Os isotopic signatures in many Itasy samples, could be attributed to assimilation of the Precambrian basement. However, with the exception of Os, the elemental and isotopic characteristics of the Itasy magmas are inconsistent with significant crustal assimilation, and instead are interpreted to represent features of their mantle sources. The Itasy DeHf and D7/4 values fall within the range of MORB and OIB, and indicate derivation primarily from an asthenospheric mantle source. The absence of significantly negative DeHf in the Itasy magmas argues against the involvement of ancient recycled oceanic crust or stranded lower crust in their sources, but the presence of a low m (LOMU) component in some Itasy magmas can be attributed to pollution of the asthenosphere by delaminated subcontinental lithospheric mantle. A simple two-stage, three-component mixing model indicates that a mixture of mantle containing 90% depleted asthenosphere (DMM) and 10% foundered SCLM, which is further mixed with 30 to 50 % of a plume-type mantle component, can reproduce the isotopic compositions of the Itasy magmas. Based on our model, it is possible that easily fusible superplume materials might be widely distributed in the upper mantle underneath the EARS, from the Indian Ocean to the Red Sea-Gulf of Aden, and mixed with shallow asthenosphere that has itself incorporated eroded SCLM. These components are heterogeneously distributed at a small spatial scale, similar to that observed recently in other mafic monogenetic volcanic fields in both intraplate and subduction settings.

title: Geochemical records reveal continued and differential marine redox change associated with Late Ordovician climate and mass extinctions

description: The Ordovician (Hirnantian; 445 Ma) hosts the second most severe mass extinction in Earth history, coinciding with Gondwanan glaciation and a growing geochemical evidence for marine anoxia. It remains unclear whether cooling, expanded oxygen-deficiency, or a combination drove the Late Ordovician Mass Extinction (LOME). Here, we present combined iodine and sulfur isotope geochemical data from three globally distributed carbonate successions to constrain changes in local and global marine redox conditions. Iodine records suggest locally anoxic conditions were potentially pervasive on shallow carbonate shelves, while sulfur isotopes suggest a reduction in global euxinic (anoxic and sulfidic) conditions. Late Katian sulfate-sulfur isotope data show a large negative excursion that initiated during elevated sea level and continued through peak Hirnantian glaciation. Geochemical box modeling suggests a combination of decreasing pyrite burial and increasing weathering are required to drive the observed negative excursion suggesting a ~3% decrease of global seafloor euxinia during the Late Ordovician. The sulfur datasets provide further evidence that this trend was followed by increases in euxinia which coincided with eustatic sea-level rise during subsequent deglaciation in the Late Hirnantian. A persistence of shelf anoxia against a backdrop of waning then waxing global euxinia was linked to the two LOME pulses. These results place important constraints on local and global marine redox conditions throughout the Late Ordovician and suggest that non-sulfidic shelfal anoxia—along with glacioeustatic sea level and climatic cooling—were important environmental stressors that exacerbated worsened conditions for marine fauna, resulting in the second-largest mass extinction in Earth history and the only example during an icehouse climate

title: Secondary Ion Mass Spectrometry standards for lithium in carbonaceous matrices

description: The data includes SIMS depth profile results of Li implants into polymers, carbon glass and NIST 612 silicate glass standards. The goal of this research was to evaluate potential matrix effects for Li in kerogen. Because kerogen is not homogenous, polymers of similar compositions to kerogen were created via Li ion implantation to serve as standards for kerogen. We were particularly interested in how varying compositions of C, H and O may affect the content and isotope calibration of Li in kerogen. The data included contain individual measurements of SIMS depth profiles as well as the calculations for the determination of Li content calibration factors, sputter yields, useful ion yields, etc.

title: Chemical Heterogeneities Reveal Early Rapid Cooling of Apollo Troctolite 76535

description: The evolution of the lunar interior is constrained by samples of the magnesian-suite of rocks returned by the Apollo missions. Reconciling the paradoxical geochemical features of this suite constitutes a feasibility test of lunar differentiation models. Here we present the results of a microanalytical examination of the archetypal specimen, troctolite 76535, previously thought to have cooled slowly from a large magma body. We report a degree of intra-crystalline compositional heterogeneity (phosphorus in olivine and sodium in plagioclase) fundamentally inconsistent with prolonged residence at high temperature. Diffusion chronometry shows these heterogeneities could not have survived magmatic temperatures for &gt;20.1 My, i.e., far less than the previous estimated cooling duration of &gt;100 My. Quantitative modeling provides a constraint on the thermal history of the lower lunar crust, and the textural evidence of dissolution and reprecipitation in olivine grains supports reactive melt infiltration as the mechanism by which the magnesian suite formed.
