The Earth's continental crust provides us with a rich and complex geological history. Sandwiched between the upper mantle and the above atmosphere, the continental crust is affected by deep-seated and near-surface processes which ultimately promote the formation of mineral resources that are the building blocks of our society. 
Such processes occur in variable geodynamic environments and contribute to the heterogeneity of the crust. While igneous processes play a key role in generating new crust, large volumes of the pre-existing crust are transformed by metamorphic processes and partially recycled back into the mantle during subduction. In addition, weathering and erosion regulate the preservation potential of the crust and associated mineral deposits.
In this session, we foster a wide-angle discussion on the variety of magmatic, magmatic-hydrothermal and metamorphic processes that shape the continental crust at different depths and time, including the geochemical and mineralogical transformations that occur when crust meets the atmosphere.
We welcome contributions targeting field-based observations, petrological, geochemical and geochronological data, from bulk rock analyses as well as in situ measurements, including novel isotopic measurements of key archive minerals and fluid/melt inclusions.
