Controls on source and depth of emplacement of granitic magma

Abstract

Large granitic batholiths emplaced in high grade metamorphic rocks at mid-crustal levels were relatively hydrous compared with major batholiths emplaced at very shallow levels. Those emplaced at mid-crustal levels were probably generated by partial melting of crustal rocks at only slightly deeper levels. Those emplaced at shallow levels are associated with penecontemporaneous volcanic ejecta and were probably generated at deep crustal or possibly mantle depths. (Author's abstract)
