We introduce a novel high-precision method for oxygen-isotope analysis of iron (oxyhydr)oxides using high-temperature conversion isotope ratio mass spectrometry (HTC-IRMS). In this approach, a finely ...

Isotope analysis of limestone cave deposits indicates repeated humid periods in the Saharo-Arabian Desert over the past eight ...

Originally, the hypothesis was that Theia gave the Earth a glancing blow, and the proto-Earth and Theia lost pieces ending up as one or two moons that eventually formed the Moon. It was thought that a ...

An international team of geoscientists, marine geologists, climatologists, and environmental specialists has found that lingering El Niño events have increased in frequency over the past 7,000 years.

New Curtin-led research has revealed that water played a far bigger role than previously thought in shaping Earth's first ...

Earth's oceans could one day turn purple. Nearly three fourths of Earth is covered by oceans, making the planet look like a ...

Besides the water seen flowing in lakes and rivers or frozen in glaciers and ice caps, most freshwater goes unseen in underground aquifers. Isotope hydrology, a form of nuclear science, comes into the ...

Community-weighted mean foliar stable carbon isotope signatures are mainly affected by environmental factors in meadow and typical steppes, and by leaf traits in desert steppes, according to field ...

Chengdu University of Technology-led research has established a high-resolution astrochronological framework spanning ...

The Boise State University Isotope Geology Laboratory (IGL) is a state-of-the-art geoanalytical facility for the analysis of trace elements and radiogenic isotopes in Earth materials, using both ...
