Turning to Stone: Discovering the Subtle Wisdom of Rocks

Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet.

Contrary to their reputation, rocks have eventful lives-and they intersect with our own in surprising ways. In Turning to Stone, Bjornerud reveals how rocks are the hidden infrastructure that keep the planet functioning, from sandstone aquifers purifying the water we drink to basalt formations slowly regulating global climate.
