Earth's near-surface mineralogy has diversified over more than 4.5 b.y. from no more than a dozen preplanetary refractory mineral species (what have been referred to as "ur-minerals" by Hazen et al., 2008) to around 5,000 species (based on the list of minerals approved by the International Mineralogical Association; http://rruff.info/ima). This dramatic diversification is a consequence of three principal physical, chemical, and biological processes: element selection and concentration (primarily through planetary differentiation and fluidrock interactions); an expanded range of mineral-forming environments (including temperature, pressure, redox, and activities of volatile species); and the influence of the biosphere.

Canada's diverse landscape speaks to its fascinating geological history, from towering peaks to Prairie plains, from fertile farmlands of the Great Lakes and St. Lawrence Lowlands to rugged cliffs of the Atlantic shore. However, the modern landscape is just the latest episode in an epic story spanning more than 4 billion years. Four Billion Years and Counting unveils the geological history of Canada and makes connections between geology and social issues such as climate change, hazards such as landslides and earthquakes, and other environmental factors. The text features contributions from some 100 specialists, and is richly illustrated with over 500 colour photographs and diagrams. Four Billion Years and Counting is a fascinating exploration of Canada's geology for those who are intrigued by the landscape and the vital connection between ourselves and what lies beneath our feet.
