Five silica grains were found earlier, but, because of their isotopic compositions, they are thought to originate from AGB stars, red giants that puff up to enormous sizes at the end of their lives and are stripped of most of their mass by powerful stellar winds.
The proposed method, based on strong experimental modelling interaction, includes innovative tools such as (1) the intensive use of the recently developed triple isotopic composition of oxygen in water for constraining water isotopic fractionation, hydrological cycle organisation and potentially stratospheric water input, (2) the development of a laser spectroscopy instrument to accurately measure this parameter in water vapour, (3) modelling development including stratospheric tracers (e.
Among the topics are the nitrogen isotopic analysis of dissolved inorganic and organic nitrogen in soil extracts, the role of meiofauna in deep-sea benthic food webs revealed by carbon and nitrogen stable isotope analysis, fish scales as a record of atmospheric change, estimating transpiration from the oxygen isotope composition of leaf organic matter, and an improved method for the precise determination of carbon isotopic composition of amino acids.
Using cutting-edge technology, they measured the isotopic composition of tungsten, a very rare element which, like gold and other heavy precious metals, gravitated to Earth's centre during the formation of the core.
Following an overview of the field, papers describe recent methodological advances, including an automated counting system for fission tracks in natural minerals, the use of laser ablation inductively coupled plasma mass spectrometry for measuring uranium concentration for apatite and zircon fission-track chronometry, and detrital thermochronology based on measuring Nd isotopic compositions on single apatites by laser ablation ICP-MS, to cite a few examples.
