Mineralogy and mineral chemistry of Variscan granitoids from Highiş Mts. (Apuseni Mts., Romania)

The Apuseni Mts. is built up by nappe systems of continental crust origin (Apusenides), and oceanic crust related nappe systems (Transilvanides). The Apusenides were formed during the pre-Gosau tectogenesis and are built up by the autochthonous Bihor Unit and two overthrust units: the Codru and Biha...

Description
Summary:The Apuseni Mts. is built up by nappe systems of continental crust origin (Apusenides), and oceanic crust related nappe systems (Transilvanides). The Apusenides were formed during the pre-Gosau tectogenesis and are built up by the autochthonous Bihor Unit and two overthrust units: the Codru and Biharia Nappe Systems, which contain granitoid intrusions of Variscan age. These major Alpine tectonic units are represented in the Highiç Mts. by the Fini? Nappe (Codru Nappe System) and the Highiç-Muncel Nappe (Biharia Nappe System). The granitoid rocks of the two nappe systems differ significantly: the intrusions of the Codru Nappe System are syenogranites of calc-alkali character with biotite of high Mg and low Alv ' content, accompanied by primary and secondary muscovites, while those of the Biharia Nappe System are syenogranites of subalkali character, with biotites of low Mg content, and primary muscovites.
