High-Pressure Melting of Eclogite and the P-T-X History of Tonalitic to Trondhjemitic Zoisite-Pegmatites, Munchberg Massif, Germany

Episodic fluid action during exhumation of deeply subducted continental crust: Geochemical constraints from zoisite–quartz vein and host metabasite in the Dabie orogen

“…As observed in natural HP/UHP metamorphic rocks in the Dabie-Sulu orogenic belt, felsic veins precipitated from partial melts are of granitic composition, with occurrence of almost the same mineral assemblages as granite (Liu et al, 2010c;Wallis et al, 2005;Zeng et al, 2011;Zong et al, 2010b). Zoisite-bearing pegmatite within eclogite in the Munchberg Massif (Franz and Smelik, 1995;Liebscher et al, 2007) and felsic vein within UHP eclogite at Xitieshan in North Qaidam would form by partial melting of eclogite. They contain abundant feldspar and are of granitic composition.…”

Monazite in a Variscan mylonitic paragneiss from the Münchberg Metamorphic Complex (NE Bavaria) records Cadomian protolith ages

“…The peak P-T conditions of these eclogites were estimated by several studies (Franz et al, 1986;Klemd, 1989;Klemd et al, 1991Klemd et al, , 1994O'Brien, 1993;Liebscher et al, 2007). These conditions cluster in the P-T range of 20-34 kbar and 550-750°C.…”

Experimental and crystal chemical study of the basalt–eclogite transition in Mars and implications for martian magmatism

“…This study shows that garnet is the restite phase which endures through complete melting of omphacite. In fact, to show how enriched melt from eclogite can be, Liebscher et al (2007) produced pegmatites from small degrees of partial melting. Figure 14 is a schematic diagram to illustrate a proposed melting model.…”
