WebHypersolvus granites mainly consist of alkali feldspars, quartz, micas (e.g. biotite, muscovite) , and amphiboles (e.g. riebekite). As minerals crystallize from the melt, they … WebAccording to this interpretation, the hypersolvus granite is the product of extreme fractional crystallization of a parent syenitic magma.

WebThe central mass of the pluton consists mainly of hornblende-biotite granodiorite and less tonalite, its border facies is granodiorite to granite. Associated dykes are mainly granodioritic. Amphibole geothermobarometry indicates pluton emplacement at initial maximum P ≈ 3.1 ± 0.6 kbar and T between 748° to 718 °C under hypersolvus conditions.
