Glasses And Melts: Linking Geochemistry And Materials Science, October 2006, Vol. 2, No. 5
$20.00Geological interest in studying melts stems from early recognition that melts play a fundamental role in determining the physical and chemical behaviour of magmas and magmatic processes. However, due to the inherent difficulties associated with working at high temperatures, much of the geological research over the last 30 years has used quenched melts or glasses as proxies for melts themselves.

Early Earth, August 2006, Vol. 2, No. 4
$20.00The earliest Earth was a strange inhospitable world, yet transitions occurred culminating in the evolution of life within the first billion years. The preservation of a sparse and ambiguous rock record has encouraged debate.

Water On Mars, June 2006, Vol. 2, No. 3
$20.00During the past several decades, spacecraft data have transformed the planets from astronomical objects into geologic worlds. Mars is the current focus of planetary exploration, and NASA’s objectives for this effort are based on the theme, “follow the water.

Arsenic, April 2006, Vol. 2, No. 2
$20.00Arsenic is an element known throughout history as a classic poison. Currently, very small but highly significant concentrations of this element in drinking water supplies are causing massive health problems to many millions of people in some of the world’s poorest nations, and more localised sources related to mining and processing are also a concern.

User Research Facilities In The Earth Sciences, February 2006, Vol. 2, No. 1
$20.00Earth scientists rely on effective access to user research facilities that provide state-of-the-art analytical instrumentation. This thematic issue focuses on some of these facilities and how to use them.

Toxic Metals In The Environment: The Role Of Surfaces, September 2005, Vol. 1, No. 4
$20.00Metals are prevalent in the environment. They are derived from both natural and anthropogenic sources.

Genesis: Rocks, Minerals, And The Geochemical Origin Of Life, June 2005, Vol. 1, No. 3
$20.00Few scientific questions so capture the public imagination, or provoke such lively debate, as how life on Earth emerged. In this issue of Elements, four of the most creative minds in origins research present their original insights on the geochemical origins of life.

Diamonds, March 2005, Vol. 1, No. 2
$20.00Diamond, the fascinating ultrahard mineral, is the focus of considerable interest and scientific research. Recent advances particularly relevant to geoscientists include: diamond as a recorder of Earth processes from the perspective of inclusions, chemistry, and conditions of formation; synthesis for research applications and processing to modify color and physical properties, important to diamond gems and anvils; the implications of nanodiamonds from meteorites.

Fluids in Planetary Systems, January 2005, Vol. 1, No. 1
$20.00Water and other geofluids play an important role in the geochemical and rheological evolution of the Earth and other bodies in the solar system. These fluids are responsible for the formation of hydrothermal mineral deposits, affect eruption behavior in volcanic systems and the geophysical properties of the mantle, and significantly affect the way in which rocks deform and fracture.

Large Igneous Provinces: Origin And Environmental Consequences, December 2005, Vol. 1, No. 5
$20.00Large igneous provinces record major outpourings of igneous rocks, both on the continents and in ocean basins. Their origin is still vigorously disputed, with models invoking mantle plumes, thermal effects of the lithosphere, and meteorite impacts.
