## GeodynamicsFirst published in 1982, Don Turcotte and Jerry Schubert's Geodynamics became a classic textbook for several generations of students of geophysics and geology. The authors bring this text completely up-to-date in this second edition. Important additions include a chapter on chemical geodynamics, an updated coverage of comparative planetology based on recent planetary missions, and a variety of other new topics. Geodynamics provides the fundamentals necessary for an understanding of the workings of the solid earth, describing the mechanics of earthquakes, volcanic eruptions, and mountain building in the context of the role of mantle convection and plate tectonics. Observations such as the earth's gravity field, surface heat flow, distribution of earthquakes, surface stresses and strains, and distribution of elements are discussed. |

#### Review: Geodynamics

User Review - Nathan Katsiaficas - GoodreadsI mean all of these books are dry, but Geodynamics by Turcotte and Schubert is a great reference book for any geophysicist/geologist interested in modeling or mantle dynamics/geophysics. I'd also recommend The Solid Earth by Fowler. Read full review
