Greenalite [Fe3Si2O5(OH)4] is an iron-rich Fe(II)-serpentine mineral first identified in the Lake Superior iron formations more than a century ago. Today, with the help of advanced in-situ nanoscale imaging techniques, scientists are uncovering the true significance of this microscopic mineral in shaping Earth’s geological history. Recent research highlights nanoparticulate greenalite as a key contributor to the formation of early Precambrian banded iron formations (BIFs), offering new insights into the chemistry of ancient oceans and the evolution of the planet’s early atmosphere.

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.

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.
