Metal Stable Isotopes, December 2009, Vol. 5, No. 6
$20.00During the past decade it has been recognized that the stable isotope compositions of several metallic elements vary significantly in nature due to both biotic and abiotic processing. While this leap in our understanding has been fueled by recent advances in instrumentation and techniques in both thermal ionization and inductively coupled plasma mass spectrometry, the field of metal stable isotope geochemistry has finally moved beyond a focus on development of analytical techniques and toward using the isotopes as source and process tracers in natural and experimental systems.

Gold, October 2009, Vol. 5, No. 5
$20.00Gold fascinates researchers in many sciences. As well as being attractive as a precious metal, gold has important physical and electrical properties that cause it to be an ’advanced material’ for manufacturing and drug delivery in medical science.

Mineral Magnetism: From Microbes To Meteorites, August 2009, Vol. 5, No. 4
$20.00Magnetic minerals are ubiquitous in the natural environment. They are also present in a wide range of biological organisms, from bacteria to human beings.
-
Gems, June 2009, Vol. 5, No. 3
$20.00Most gems are natural minerals, which, although scarce and small, have a major impact on society. Their value is directly related to proper identification.

Bentonites – Versatile Clays, April 2009, Vol. 5, No. 2
$20.00Of all naturally occurring clays, bentonites are arguably the most interesting, versatile and useful. This issue of Elements describes how these fascinating materials occur and how they are used in all manner of applications.

Scientific Exploration Of The Moon, February 2009, Vol. 5, No. 1
$20.00Our current understanding of the Moon’s history, interior structure, and chemical composition is based in large part on geochemical data acquired from samples from the U.S.

Nanogeoscience, December 2008, Vol. 4, No. 6
$20.00At first glance, nano and Earth seem about as far apart as one can imagine. Nanogeoscience seems to be a word connecting opposites.
-
Carbon Dioxide Sequestration, October 2008, Vol. 4, No. 5
$20.00Storage of carbon in the subsurface involves introduction of supercritical CO2 into rock formations beneath the surface of the Earth, typically at depths of 1000 to 4000 meters. Although CO2 is a relatively benign substance, the volume being considered is large.
-
Platinum-Group Elements, August 2008, Vol. 4, No. 4
$20.00The geoscientific and economic significance of the PGE is immense. Due to their extreme siderophile and chalcophile behaviour, the PGE are highly sensitive tracers of geological processes involving metal and sulfide phases.
-
Deep Earth And Mineral Physics, June 2008, Vol. 4, No. 3
$20.00The field of high-pressure mineral physics is central to our understanding of the Earth’s interior and its evolution. It is also a field that is rapidly advancing.

Phosphates And Global Sustainability, April 2008, Vol. 4, No. 2
$20.00Phosphorus is a unique element: it is essential to the existence of all living forms, and as such controls biological productivity in many terrestrial and marine environments; but when in excess, it leads to uncontrollable biological growth and water-quality problems. This has become a common environmental issue, resulting from our careless use of phosphorus in agriculture, yet phosphate ore deposits, from which fertilizers are produced, are a finite natural resource.

Supervolcanoes, February 2008, Vol. 4, No. 1
$20.00Explosive super-eruptions from large volume, shallow magma systems lead to enormous and devastating pyroclastic flows, the formation of gigantic collapse calderas, and deposition of volcanic ash over continent-sized areas. Recognition that future eruptions from these “supervolcanoes” will undoubtedly have severe impacts on society—and perhaps on life itself—has led to recent public and media interest.
