Korenaga and coworkers presented evidence to suggest that the Earth's mantle was dry and
water filled the ocean to twice its present volume 4.3 billion years ago. Carbon dioxide was …

The CHONS elements that constitute the outgassed atmosphere and exosphere have likely
been delivered by chondritic materials to the Earth during planetary accretion and …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

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 …

The origin of life on Earth seems to demand a highly reduced early atmosphere, rich in CH
4, H 2, and NH 3, but geological evidence suggests that Earth's mantle has always been …

The delivery of water to the inner Solar System, including Earth, is still a debated topic. A
preferential role for hydrated asteroids in this process is supported by isotopic …

Nitrogen, carbon, hydrogen and sulfur are essential elements for life and comprise about 1%
of terrestrial planet masses. These elements dominate planetary surfaces due to their …

Meteorites provide a unique insight into early Solar System processes. However, to fully
interpret this record requires that these meteorites are related back to their source asteroids …

The Moon formed 4.5 Ga ago through a collision between proto-Earth and a planetesimal
known as Theia. The compositional similarity of Earth and Moon puts tight limits on the …

The terrestrial planets accreted from a diverse suite of solar system materials ranging from
strongly O-deficient materials similar to enstatite chondrites via ordinary chondrite materials …
