The biogeochemical cycling of metals in natural systems is often accompanied by stable
isotope fractionation which can now be measured due to recent analytical advances. In …

The silicon isotope composition of biogenic silica (δ 30 Si BSi) in the ocean is a function of
the δ 30 Si of the available dissolved Si (DSi; H 2 SiO 4), the degree of utilisation of the …

'Data is the new oil'is a phrase that is frequently employed to indicate that digital
technologies and data extraction have supplanted fossil fuels and geological extractivism as …

Silicate weathering is critical to global carbon cycle and climate change, and has attracted
considerable attention in Earth science studies. Chemical weathering intensity evaluation …

Enhanced weathering and mineralization (EWM) aim to remove carbon dioxide (CO2) from
the atmosphere by accelerating the reaction of this greenhouse gas with alkaline minerals …

All pathways which limit global temperature rise to< 2° C above pre-industrial temperatures
now require carbon dioxide removal (CDR) in addition to rapid greenhouse gas emissions …

Silicon (Si) is the second most abundant element in the Earth's crust and is an important
nutrient in the ocean. The global Si cycle plays a critical role in regulating primary …

Plants and soil microbiota play an active role in rock weathering and potentially couple
weathering at depth with erosion at the soil surface. The nature of this coupling is still …

Abstract Microaggregates (< 250 µm) are key structural subunits of soils. However, their
formation processes, rates, and transformation with time are poorly understood. We took …

In contrast to many other stable isotopes of the elements discussed in this book, those of
silicon are not strictly speaking “Non-Traditional Stable Isotopes” because they have been …
