Key Points

To establish the relationship between magma source compositions, crustal interactions, and tectonic settings to facilitate the geochemical fingerprinting of granitic rocks.
Comparative analysis of magma petrogenesis spanning pure mantle to pure crustal sources across varied tectonic regimes.
Assessment of crustal thickness, temperature, composition, and magma residence time as drivers of magma-crust interactions.
Ocean ridge and volcanic arc granites correlate with depleted mantle sources, with volcanic arcs exhibiting additional subducted oceanic crust and sediment input.
Syn-collision granites derive from pure crustal sources or mantle modified by large crustal additions, while intraplate and post-collision granites reflect enriched mantle and rare crustal melts.
