In the Variscan Western Tatra granites hybridization phenomena such as mixing and mingling can be observed at the contact of mafic precursors of dioritic composition and more felsic granitic host rocks. The textural evidence of hybridization include: plagioclase-K-feldspar-sphene ocelli, hornblende- and biotite-rimmed quartz ocelli, plagioclase with Ca-rich spike zonation, inversely zoned K-fel...

bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...

Zircons from charnockitoids of the Tashlyk complex Pryinhul syncline were studied and dated in order to determine their chronostratigraphic position. two age generations identified, namely Early Archean (ca. 3 Ga) Proterozoic (2.0±0.1 Ga). The presence former generation indicates that protolith for charnockites have been represented by rocks older than Spasove Series, which is considered be age...
