TL;DR: In this article, a multistage model was proposed to calculate the simultaneous variations in trace element concentrations and radiogenic and stable isotopic compositions that occur during water-rock interaction.

TL;DR: A clear negative relationship between precipitation and changes in soil organic carbon and nitrogen content when grasslands were invaded by woody vegetation is found, with drier sites gaining, and wetter sites losing, soilorganic carbon.

TL;DR: In this paper, the authors present a set of high-resolution, seawater Sr and C isotope curves for the late Early through early Late Cambrian, defined in continuous exposures of marine carbonates in the Great Basin and southern Canadian Rockies, and used to better constrain primary variations in ocean chemistry during this time period.

TL;DR: In this article, a quantitative evaluation of the effects of water-rock interaction on strontium concentrations and isotope compositions in carbonates is presented, which can be used to distinguish between mixing of mineral end-members and fluid-rock interactions.

TL;DR: Radiogenic isotopes have wide application to chemical stratigraphy, geochronology, provenance studies, and studies of temporal changes in Earth surface processes as discussed by the authors, and they can be used for stratigraphic correlation and to assess changes through Earth history in processes such as tectonic uplift, climate change, biogeochemical cycling, ocean circulation, crustal growth, and surface water evolution.
