Abstract Details

2004, Master of Science, Miami University, Geology and Environmental Earth Science.
Northern Albania's Mirdita ophiolite displays two distinct belts of Jurassic Neotethyan oceanic crust that developed between the Apulian and Pelagonian margins. The western belt consists of an ~3-km-thick MORB pseudostratigraphy, in which pillow lavas overlie serpentinized peridotites, suggesting tectonic extension dominated early stages of seafloor spreading. The eastern belt includes an ~10-km-thick complete pseudostratigraphy with extrusives that show increasing IAT chemistry upsection. Mutually intrusive relations between crustal units indicate robust magmatic spreading occurred. Four dike generations (D1-D4) exist based on structure, crosscutting relations, and texture. D1-D4 are composed of diabase dikes. D1 strike 030-060o, dips SE, and is crosscut by NE dipping D2 dikes oriented 290-340o. D3-D4 crosscut D1-D2 and strike of 240-290o with northerly dips. Boninite and rhyodacite dikes intruded throughout the SDC's history because of complex magmatic processes. These relations suggest the spreading direction changed from NNE-SSW to NW-SE because of the incipient Mirdita-Pelagonia collision in the South.
