Biotite, the dominant ferromagnesian mineral in granitoid rocks, can be used to discriminate tectonic setting, magma types and magnetite- ilmenite series. In this study, we analyzed biotite with an electron microprobe (wavelength dispersion) from different granitoids. Intrusive rocks from Maherabad porphyry Cu-Au prospecting are meta-aluminous. Biotite from Maherabad are Mg-rich type and the ra...

The Azov Domain occurs as a part of larger Mesoarchean (3.2-3.0 Ga) craton, fragments which are preserved in the eastern Ukrainian Shield and block Kursk Magnetic Anomaly (KMA). In Neoarchean-Palaeoproterozoic time, it was fragmented into several tectonic blocks: Vovcha, Remivka, Huliaipole, Bilotserkivka, Saltych. northern Huliaipole Block is composed tonalite-trondhjemite-granodiorite (TTG) r...

The Laiyuan complex in the central North China Craton (NCC) incorporating different magmatic suites offers an excellent opportunity to investigate lithospheric evolution and cratonic destruction. However, petrogenesis tectonic implications of this suite remain debated due lack integrated studies. Here we evaluate magmatism setting assembling data from multidisciplinary investigations complex. i...

Abstract. Back-arc extension superimposed on mountain belts leads to distributed normal faults and shear zones interacting with magma emplacement within the crust. The composition of granitic magmas emplaced at this stage often involves a large component crustal melting. Miocene Aegean granitoids were in metamorphic core complexes (MCCs) below crustal-scale low-angle ductile zones. Intrusion pr...
