Formation of Rapakivi Feldspars in the Deer Isle Granite Complex, Coastal Maine: <em>In Situ</em> Lead Isotope and Trace Element Analysis

Rapakivi and alkali feldspar phenocrysts from the Deer Isle Granite Complex were investigated using in situ trace element and Pb isotope geochemistry to see if magma mixing or isothermal decompression was responsible for their formation. Pb isotope and trace element profiles, along with CL imagery o...
