The K-replacement modifications of the Kavala megacrystal granodiorite and the Sithonia euhedral-epidote-bearing, hornblende-biotite granodiorite in northern Greece

Two of the many granitic plutons visited during the September 2-8, 1998, Eurogranites '98 field trip in northern Greece (Sideris et al., 1998) have particularly interesting textures or mineralogy. These granitic rocks are the megacrystal Kavala granodiorite (Christofides et al., 1995, and Kyriakopoulos et al., 1989), which was examined at Stop 23, and the euhedral-epidote-bearing, hornblende-biotite granodiorite of the Sithonia pluton (Christofides et al., 1990), which was investigated at Stop 32. These granitic rocks are in the Circum-Rhodope Belt (Fig. 1) and have a primary magmatic origin. In addition to their magmatic features, however, they exhibit textural features that suggest that magmatism was not the only process affecting these rocks in their histories.
