Fe-Ti-oxides may reach hundreds ppm in I-type granitoids and close to microgranular mafic enclaves (MME) up to several thousands ppm. Western Carpathian I-type granitoids have magnetic susceptibility above 3 × 10−4 SI units, whereas S-type granites are lower. Associated MMEs reach up to 160 × 10−4 SI. The measurement of magnetic susceptibility in field

Miocene extension in the Aegean Sea was accompanied by the intrusion of granitoid and monzonitic magmas at upper crustal levels. With increasing distance from the trench, the metaluminous to slightly peraluminous I-type intrusives show a systematic regional variation in their compositions: medium- to high-K granodiorites in the WSW, high-K low-silica ...

Abstract The closure of the Paleotethys ocean in the Tethyan orogenic belt in northeastern (NE) Iran, related to the collision between Gondwana-derived terranes in the south and Laurasia in the north, remains controversial due to the sparsity of Paleozoic ophiolitic outcrops but can be constrained by contemporaneous granitoids.

Abstract The Baogutu porphyry Cu deposit is a typical reduced porphyry Cu deposit, likely related to ilmenite-series I-type granitoids. However, the nature of the granitoids (ilmenite-series or magnetite-series) and the genesis of the Baogutu deposit are still under debate.

The Late Yanshanian Orogeny (130-90 Ma) encompasses an important Mesozoic magmatic event in the crustal evolution of SE China. Products of post-orogenic magmatism, widely distributed in the eastern part of Zhejiang and Fujian provinces known as the Southeast Coast Magmatic Belt (SCMB), are dominated by large amounts of slightly Nb and Ta depleted, high-
