Metamorphic complexes form by various different processes in many different tectonic settings all over the world. In order to distinguish in one particular case between different processes which formed the complex, an understanding of the spatial geometry and the temporal evolution of the complex is needed. This thesis contains the results of an interdisciplinary study conducted on the Chugach Metamorphic Complex (CMC) of southern Alaska, which aimed at constraining the evolution of the complex in space and time, in order to distinguish between different processes which formed the complex. The CMC is a 10-50 km wide and 350 km long upper amphibolite facies metamorphic complex, which consists of two macroscopically different zones: an inner migmatitic gneiss zone and an outer schist zone. The complex developed in the Late Cretaceous accretionary prism of the Chugach terrane, which is exposed along the southern Alaskan margin on 2200 km along strike.In the first chapter, the regional geology of the study area is reviewed and summarized. In the second chapter, the maximum depositional age of the sediments is constrained by LA-ICP-MS dating of detrital zircons to Paleocene-Late Cretaceous. In the third chapter, the applicability of garnet, monazite, allanite and xenotime as prograde geochronometers is tested. In the fourth chapter, the timing of peak metamorphism is constrained by U-Pb SHRIMP dating of metamorphic zircon rims to 55-52 Ma. In the fifth chapter, the structural geometry of the complex along three composite transects is described, and the cooling history of the complex based on 40Ar/39Ar dating of biotite and muscovite, Rb/Sr isochron dating and zircon fission track dating is revealed. Finally, a possible tectonic evolution of the complex is presented and is compared to previous models.
