Petrology of Păuliş granites (Apuseni Mts., Romania)

This paper presents new data of the highly evolved part of the Highis Granitoid Suite. Two types of texture represent the suite: equigranular, medium-grained leucogranites and aplite veins. Main rock forming minerals are quartz, orthoclase, microcline, plagioclase feldspar, biotite and muscovite. Based on geochemical investigations which were performed on both selected mineral phases and whole rock composition the Highi$ Granitoids from P5uli§ are S-type, felsic-peraluminous alkali granites, with alkali-calcic character, formed in post-collisional (postorogenic) tectonical setting, mainly from metasedimentary source
