Abstract The extensional Thrace basin (NW Anatolia) contains an association of early Miocene diopside–leucite–phlogopite (Doganca) and diopside–phlogopite (Korucukoy) lamproites with Oligocene medium-K calc-alkaline andesites (Kesan volcanics), early Miocene shoshonitic rocks (Altinyazi trachyte) and middle Miocene Na-alkaline basalts (Begendik basalts). The Doganca lamproite (K2O = 5.1–5.5 wt.%; K/Na = 2.78–2.89; MgO = 11.4–11.8 wt.%) consists of olivine (Fo71–86), diopside (Al2O3 = 1.0–5.0… CONTINUE READING
