Granites and the Continental Crust: Reimaging, Reinvestigating, and Reinterpreting Earth’s Veneer
Session ID#: 251566
Session Description:
The continental crust is an archive of ~4 billion years of Earth’s history, covers 41% of Earth’s surface, and represents 70% of the crustal volume on Earth. While we know a great deal about the crust, including its chemical and structural stratification and that it is relatively felsic in nature, we still debate fundamental aspects of its formation, chemistry, and structure. Determination of the internal architecture and chemistry of the continental crust is one of the key missions in the field of Geosciences and is important for understanding the long-term evolution of Earth’s surface. This session encourages submission of a diverse range of contributions which highlight methods of assessing crustal structure and magma petrogenesis within the continental crust. These studies will include those which utilize geophysical, geochemical, petrological, and geochronological approaches. We welcome contributions that apply fieldwork, laboratory investigations through experimental simulations and high-resolution analyses, advanced modeling, and statistical tools.
