Frontiers In Textural And Microgeochemical Analysis, August 2007, Vol. 3, No. 4
$20.00Recent advances have been made in high-resolution in situ methods to image mineral growth patterns, analyse compositional and isotopic zonation, and improve our ability to visualize, study, and model rock textures in three dimensions. These advances provide a significant step forward in the understanding of how rocks form and the history they can tell us.

Energy: A Geoscience Perspective, June 2007, Vol. 3, No. 3
$20.00The issue of energy resources in the future may be one of the most important in the 21st century. Future climate change and the ways to abate it while still supplying needed energy will impact future political relations, world economics, human health, and the environment.

Zircon – Tiny But Timely, February 2007, Vol. 3, No. 1
$20.00Where would Earth science be without zircon? As Earth’s timekeeper, zircon has proven to be a remarkable and versatile mineral, providing insights into deep time and ancient Earth processes. However, there is still much to learn about Earth’s history from zircon and its behaviour.

The Nuclear Fuel Cycle – Environmental Aspects, December 2006, Vol. 2, No. 6
$20.00Increasing concerns for the effects of global warming that result from rising greenhouse gas concentrations in the atmosphere have led to a reexamination, even enthusiasm, for nuclear power. Of all the current alternatives to fossil fuels, nuclear fission is the most important source of energy, accounting for 17 percent of the world’s electricity.

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.

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.
