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 …

Just as the use of new tools revolutionized lunar science in 1610 (Galileo's telescope), 1840
(photography), and 1960s–1970s and 1990s (over 45 robotic and human missions to the …

This textbook is a complete rewrite, and expansion of Hugh Rollinson's highly successful
1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Comparing compositional models of the terrestrial planets provides insights into
physicochemical processes that produced planet-scale similarities and differences. The …

The heavy iron isotopic composition of Earth's crust relative to chondrites has been
explained by vaporization during the Moon-forming impact, equilibrium partitioning between …

Understanding the nature and origin of the precursor material to terrestrial planets is key to
deciphering the mechanisms and timescales of planet formation. Nucleosynthetic variability …

Silicon and Mg in differentiated rocky bodies exhibit heavy isotope enrichments that have
been attributed to evaporation of partially or entirely molten planetesimals. We evaluate the …

The bulk chemical compositions of planets are uncertain, even for major elements such as
Mg and Si. This is due to the fact that the samples available for study all originate from …

Geochemical evidence suggests that the material accreted by the Earth did not change in
nature during Earth's accretion, presumably because the inner protoplanetary disc had …
