title: Clumped Isotope Dataset for Experimental Phosphoric Acid and CO2 Exchange Paper

description: Experiments have been conducted in which CO2 gases with varying C and O isotopic compositions and with stochastic and nonstochastic Δ47 values have been allowed to equilibrate with phosphoric acid of two concentrations in reaction vessels of varying dimensions at temperatures of 25 and 90 °C. Rates of 13C18O and 18O exchange between the CO2 and the phosphoric acid varied as a function of the length of exposure, volume of reaction vessel, acid strength, and difference of the initial Δ47 and δ18O values of the CO2 from theoretical equilibrium values. The Δ47 values were also altered by heated stainless steel surfaces such as those found within the Kiel device and other preparation systems. These results have been used to explain variations in the differences in the fractionation between 25 and 90 °C reported for calcite by different workers as well as differences in the slopes between temperature and Δ47 values produced by reacting samples at different temperatures (25 and 90 °C).

title: High-density fluid microinclusion-bearing diamonds from the De Beers Pool and Finsch mines, South Africa

description: Fifteen microinclusion-bearing fibrous diamonds from the De Beers Pool and Finsch kimberlites, South Africa, were analyzed for their major and trace element, He isotopic compositions, and nitrogen content and aggregation state. High-density fluid (HDF) microinclusions of saline compositions were found in 9 of the diamonds, silicic compositions in 1 diamond and carbonatitic in 4 diamonds. Some of the diamonds encapsulate also micro-mineral inclusions, and one diamond did not contain HDFs but rather only micro-mineral inclusions. All HDFs are enriched in incompatible elements; the fractionated nature of these patterns is more pronounced in the carbonatitic HDFs. 3He/4He isotopic ratios in the saline HDFs are 2.66-4.43 (Ra normalized) compared to 0.07-0.69 in the diamonds with silicic and carbonatitic HDF compositions.

title: Major and trace element and isotopic analysis of magmatic clinopyroxenes from a single Samoan hotspot lava.

description: The data presented here include high precision Sr and Nd isotopic analyses on individual magmatic clinopyroxenes measured by thermal ionization mass spectrometry. Major and trace element concentrations have also been measured on each cpx crystal. The magmatic clinopyroxene grains derive from a single, geochemically enriched (high 87Sr/86Sr) lava from Savai'i Island, western Samoa exhibiting the enriched mantle 2 signature. Clinopyroxenes show extreme variability in 87Sr/86Sr overlapping a significant portion of the variability observed in all Samoan shield lavas and global ocean island basalts.

title: Nutrient and lead profiles of urban harvested fruit and market fruit

description: The urban landscape is being transformed formally and informally to increase production and access to locally sourced produce. While cultivation of urban produce lowers the carbon footprint of food production by removing transportation to market, there is a lack of studies that investigate both toxic element profiles and nutrient content of produce in these non-traditional settings. In this study, we examined the lead (Pb) content and essential nutrient profiles of fruit harvested from the Greater Boston urban landscape in settings ranging from city streets to urban parks to residential and commercial properties. Partnering with League of Urban Canners (LUrC), a local urban harvesting organization, we created, followed, and assessed a modified participatory action research model that we call the Flashlight Model. Fruit samples were analyzed using X-ray fluorescence, a novel, environmentally sustainable, and economically feasible method to investigate the elemental composition of produce.

title: Volumetric evolution of plagioclase-hosted melt inclusions during incremental heating

description: We present a database detailing the volumetric evolution of plagioclase-hosted melt inclusions during incremental heating on a heating stage. The heating experiments were designed to induce volumetric re-equilibration. At ~40°C above the temperature at which the daughter minerals melted, irreversible volume expansion lowered the pressure in the melt inclusions, and led to exsolution of CO2 into vapor bubbles. With each additional few degrees of heating, additional episodes of CO2 exsolution, bubble nucleation and expansion of the vapor bubbles occurred. Re-equilibration of melt inclusions in plagioclase occurred through a combination of ductile and brittle deformation of the host surrounding the nelt inclusions. The volumetric evolution of the vapor bubbles and melt inclusions were estimated from both microtomography (3D) and photographs (2D).

title: Chemical-physical parameters, major, minor, trace elements, isotope determinations (D/H and 18O/16O), dissolved gases, helium isotope and d13C_TDC (TDC = total dissolved carbon) composition of groundwater from 8 wells island of Salina (Aeolian arc, Italy)

description: Geochemical prospection has been a useful tool to understanding the fluid circulating processes over the volcanic island of Salina. The geochemical results have highlighted the existence of reservoirs of both fresh and thermal water although only a few natural manifestations, mainly occurring in submarine environment, provide clues of their existence. The thermal waters, collected at a temperature of 32-36°C, show a typical marine recharge with equilibrium temperatures estimated to be in the range of 120-160°C. As matter of fact, the small island holds relatively large reservoirs of both fresh and thermal waters. The geochemical features of the circulating fluids are driven by water-rock and gas-water interaction processes, while the heat supplied to the geothermal reservoir comes from volcanic rocks that are still cooling down after the end of the last volcanic activity supposed to be not older than 13ky. The collected results allowed us to recognize the contemporary presence of high-temperature geothermal fluids and cold, fresh, waters which geochemical features mark the occurrence of Gas-Water (GWI) and Water-Rock Interaction (WRI) processes responsible for the chemical and isotopic composition of the waters and the dissolved gases. Records include:Chemical-physical parameters, major, minor, trace elements, isotope (D/H and 18O/16O), dissolved gases, helium isotope and d13CTDC (TDC = total dissolved carbon) composition of groundwater from 8 wells island of Salina (Aeolian arc Italy).
