Variations within individual cratons, as well as across different cratons, are readily apparent at the Earth’s surface, providing indirect insight into the processes governing the formation and evolution of the underlying regions. However, our views at depth are more limited. As such, there is a risk of interpreting the cratonic lithosphere as a monolith. Recent modeling and advances in seismological imaging have enhanced our perspective of vertical variations within the cratonic lithosphere, which has helped build a general conceptual model. While lateral variations also are increasingly identified, their significance still presents unanswered questions. In this review, we summarize the current state of knowledge of cratonic lithospheric structure and demonstrate the importance of lateral heterogeneity in craton evolution and stability.
期刊介绍:
Elements is an international magazine of mineralogy, petrology, and geochemistry.
Published bimonthly, every issue explores a theme of broad and current interest. Elements publishes invited peer-reviewed articles for each thematic collection of papers. Topics of interest can be proposed to the editors who will review every proposal submitted.
Elements also presents regular features including a opinion articles, calendar of events, short course announcements, awards, conference reports, policy news, as well as news of the 18 participating societies.
