Iowa Population Exposures to Metals and Metalloids in Well Water

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

High-temperature dolomite in the Lower Cretaceous Cupido Formation, Bustamante Canyon, northeast Mexico: petrologic, geochemical and microthermometric constraints

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The Lower Cretaceous Cupido Formation, a carbonate system developed in northeastern Mexico, like many ancient carbonate platforms contains numerous dolomite bodies.

Primary metabolites in root exudates are not affected by long‐term soil warming in a temperate forest

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Primary metabolites in root exudates are essential for plant nutrition and rhizosphere microbiome function, potentially responding sensitively to climate warming. However, the effects of long‐term soil warming on exudate metabolites in forests remain unclear.

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

open access: yesIntegrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Ceramic Production and Geodiversity in Iron Age Iberia: An Archaeometric Study of Pottery from Castrejón de Capote (SW Spain)

open access: yesArchaeometry, EarlyView.
ABSTRACT The hillfort of Castrejón de Capote is one of the best investigated settlements of Late Iron Age southwest Iberia. Located in the territory that the classical sources attributed to the Celtici, it was occupied between the early 4th and the 1st centuries bce.

Beachrock formation influenced by co‐seismic deformation and relative sea‐level changes during the Holocene near the Gulf of Saros, Türkiye (NE Aegean Sea)

open access: yesBoreas, EarlyView.
This is the first proof of beachrock found on the nearshore of the Gulf of Saros. Beachrock generation was influenced by tectonic activity, geomorphological processes, and sedimentation. The Late Holocene beachrock deposits were altered by co‐seismic deformation.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

open access: yesBoreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Oxygen isotope composition of the Phanerozoic ocean and a possible solution to the dolomite problem

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance The elemental and isotopic compositions of seawater have evolved throughout Earth’s history, in tandem with major climatic, tectonic and biologic events, including the emergence and diversification of life.

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

Genesis and reservoir preservation mechanism of 10 000‐m ultradeep dolomite in Chinese craton basin

open access: yesDeep Underground Science and Engineering
The 10 000‐m ultradeep dolomite reservoir holds significant potential as a successor field for future oil and gas exploration in China's marine craton basin.
