Over the last 30 years, geochemical research has demonstrated that abiotic methane (CH4),
formed by chemical reactions which do not directly involve organic matter, occurs on Earth in …

Earth is unique among the terrestrial planets in our solar system in having a fluid envelope
that fosters life. The secrets behind Earth's habitable climate are well-tuned cycles of carbon …

The isotopic compositions of terrestrial hydrogen and nitrogen are clearly different from
those of the nebular gas from which the solar system formed, and also differ from most of …

Compositional models of the Earth are critically dependent on three main sources of
information: the seismic profile of the Earth and its interpretation, comparisons between …

Groundwater is an increasingly important resource to human populations around the world,
and the study and protection of groundwater is an essential part of hydrogeology-the subset …

Carbon geochemistry of mantle-derived samples suggests that the fluxes and reservoir sizes
associated with deep cycle are in the order of 1012–13gC/yr and 1022–23g C, respectively …

This book discusses the fundamental concepts of using noble gas geochemistry to resolve
problems in the earth and planetary sciences, such as the origin of the solar system …

The trends delineated by D and 18 O contents of water discharges, from a wide range of
geothermal and volcanic systems along convergent plate boundaries around the Pacific …

Owing to advances in microanalytical techniques over the last 15 years, there is a growing
database on the volatile contents of subduction-related magmas as recorded in melt (glass) …

Over long periods of time (~ Ma), we may consider the oceans, atmosphere and biosphere
as a single exospheric reservoir for CO2. The geological carbon cycle describes the inputs …
