This study investigates the mineral chemistry of the Güneşli granite, indicating crustal melting in the Menderes massif, suggesting deep origins for these granites.
Key Points
Güneşli granite's mineral chemistry reveals deep crustal origins for these rocks, indicating significant crustal melting processes.
Thermobarometric calculations based on biotite show magma crystallized at 5.8 to 10.5 kbar and temperatures of 723 to 779 °C, deeper than expected.
The study identifies that both biotite and muscovite are of magmatic origin while showing no signs of post-magmatic alteration or weathering.
Magma evolution is attributed to assimilation-fractional crystallization processes during the development of the region's geological structures.
