CRYSTALLIZATION AND COOLING OF SİMAV MIGMATITES AND THEIR TECTONIC SIGNIFICANCE EVIDENCE FROM U Pb and Ar Ar GEOCHRONOLOGY

open access: yes, 2015
The migmatites associated with pegmatites and (leuco)granites occur in the footwall of the Simav detachment fault. As in the case of other core-complexes worldwide, the co-existence of these rocks imply intimitate spatial and temporal relationships among

Melt segregation and magma flow in migmatites: implications for the generation of granite magmas

open access: yes, 1996
:To form a granite pluton, the felsic melt produced by partial melting of the middle and lower continental crust must separate from its source and residuum.

From migmatites to granitoids

open access: yes
Melting processes in the continental crust are responsible for crust formation and recycling, and play an important role in heat transport. A better understanding of these processes can shed light on crustal differentiation and continental growth throughout the Earth’s history. This thesis focuses on three major key aspects of the link between the melt
