Crustal control on the petrogenesis of adakite-like rocks
Adakite-like rocks have attracted extensive interest as they record magmatic processes and mantle-crustal ma- terial recycling, and because they are associated with major porphyry Cu deposits. However, their petrogenesis is still under debate. In this study, we compiled ca. 7000 sets of whole-rock geochemical and Nd isotopic data of Phanerozoic adakite-

An overview of adakite petrogenesis
The term adakite was originally proposed to define silica-rich, high Sr/Y and La/Yb volcanic and plutonic rocks derived from melting of the basaltic portion of oceanic crust subducted beneath volcanic arcs. It was also initially believed that adakite only occurs in convergent margins where young and thus still hot oceanic slabs are being subducted, but

Unraveling the link between worldwide adakite-like rocks and porphyry Cu deposits
Adakite-like rocks, as an important recorder of magmatic evolution in mantle and crust, are closely associated with major porphyry Cu deposits. However, the underlying mechanism connecting these associations remains insufficiently elucidated.

Adakites and adakitic melts: Compositions of rocks, quenched glasses, and inclusions in minerals
Petrology, 2017Data set of rocks and glasses whose compositions correspond to the term “adakite” (SiO2 > 56 wt %, Sr > 400 ppm, Sr/Y > 18) was compiled from two large geochemical data bases. It was revealed that the adakitic melts are characterized by extremely low abundance as compared to adakitic rocks.

A review of research on adakites
International Geology Review, 2019Taking account of their importance in inferring continental geodynamic processes, adakites have been the subject of considerable research since their discovery and identification.

Abstract Late Paleocene adakitic granitoids are rare in Iran except in the northwest. We focused on the adakitic Saqqez-Takab pluton, which occupies an area of ~600 km2. New U-Pb zircon dating yield crystallization ages of 58–56 Ma (Thanetian). These granitoids comprises granite, quartz monzonite and monzogranite with granular to mylonitic textures ...
