Architecture of Kinematics and Deformation History of the Tertiary Supradetachment Thrace Basin: Rhodope Province (NE Greece)

摘要: The Rhodope province in Northern Aegean region where the Thrace basin, one of largest Tertiary basins this region, is located (Fig. 1) belongs to a highly extended continental terrain during time. Recent studies indicate that extensional deformation began Eocene (Kilias et al., 1999; Burchfiel 2003, Brun & Sokutis, 2007) or earlier Early Paleocene (Bonev 2006). Dinter Royden (1993), al. (1995) and Wawrenitz Krohe (1998) suggest onset extension can be set Miocene. Extension took place simultaneously with compression at more external parts Hellenides 1; Schermer 1990; Kilias 1991, Jolivet 2010). Extensional crustal subsidence are often temporally spatially associated uplift/exhumation metamorphic rocks (Friedmann Burbank, 1995; McClaughry Gaylord, 2005). Two end-members recorded continuous tectonism, which are: rift supradetachment 1995). differences magnitude rate extension, volcanism, heat flow structural architecture define basin style tectonic setting related evolution McClaughroy formed on massif Greece Strandja Sankarya massifs NW-ern Turkey 1, 2).
