Crete and the Minoan Terranes: Age constraints from U-Pb dating of detrital zircons

Popis výsledku v původním jazyce

U-Pb dating of detrital zircons separated from paragneiss of eastern Crete yielded peaks in 207Pb/206Pb ages at 0.6, 0.8, 1.0, 2.0, and 2.5 Ga with Mesoproterozoic age gap between 1.1 and 1.6 Ga. These data are compatible with U-Pb zircon ages of surrounding crystalline complexes of the Cyclades, the Menderes Massif, Egypt and the Levant. Possible provenances are the Sahara metacraton, the Arabian-Nubian Shield, and the Kibaran belt of central Africa. The age spectra of the studied East-Mediterranean crystalline complexes differ significantly from those of the Cadomian-Avalonian type terranes. They are, therefore, regarded as a separate collection of peri-Gondwanan terranes referred to as Minoan terranes. In late Neoproterozoic to ?Cambrian times, thelatter underwent Andean-type orogeny at the northern border of East Gondwana. There is no evidence that the Minoan terranes traveled for a long distances in Phanerozoic times.
