Iron isotope fractionation has emerged as a critical tracer for deciphering the complex biogeochemical cycling of iron in soils. This process, whereby natural variations in the relative abundance of ...

A team of researchers at The University of New Mexico has uncovered how a peculiar, prehistoric plant might unlock new ways to reconstruct Earth's ancient climate. Led by UNM Earth and Planetary ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when ...

A research team led by Prof. SHEN Yan'an from the University of Science and Technology of China (USTC) has made significant progress in studying the sources and formation mechanisms of haze. Through ...
