Ozgenc, I.Ilbeyli, N.2024-09-182024-09-1820090930-07081438-1168https://doi.org/10.1007/s00710-008-0027-0https://hdl.handle.net/20.500.12483/13143Late Cretaceous alkali magmatic rocks occur widely in the Hasancelebi and Basoren regions (Malatya). The Hasancelebi and Basoren intrusive rocks are mainly peralkaline and alkaline-oversaturated. The Hasancelebi intrusive rocks are made up of syenite to quartz monzonite. On the other hand the Basoren intrusive rocks mainly contain feldspathoidal syenites that are cut by feldspathoid-bearing dykes. The Hasancelebi intrusive rocks show comparable field, petrographic and geochemical characteristics with A-type rocks. All intrusive rocks show enrichment in LILE and LREE relative to HFSE. The Th/Yb versus Ta/Yb diagram indicates that all magmatic rocks formed from an enriched mantle source region(s). The parental magma for the Basoren rocks has a higher intraplate component than that from the Hasancelebi rocks which could be attributed to mantle source heterogeneity before collision in east-central Anatolia. Either delamination of the thermal boundary layer or slab-breakoff are likely mechanisms for the initiation of post-collisional magmatism in the Hasancelebi-Basoren areas.eninfo:eu-repo/semantics/closedAccessA-Type GranitoidsCrystalline ComplexCollisionOriginMantleMineralizationEvolutionCrustalRocksAreaArticle951-2718510.1007/s00710-008-0027-02-s2.0-59649085750Q2WOS:000262830000004Q3
