new calcium copper silicate liebauite has been found in cavities of a mudstone xenolith from the Sattelberg scoria cone near Kruft in the Eifel district, Germany. It occurs as bluish-green transparent crystals with a vitreous lustre and a Mohs hardness between 5 and 6. The analytical formula for liebauite based on 26 oxygen atoms is Ca2.99Cu4.91SÍ9.05O26, the idealized formula is Ca3Cu5SÍ9026, and the structural formula Ca6Cu10{lB,lL,}[14Si18O52]. The mineral is monoclinic, space group C2/c with a = 10.160(1), ¿=10.001(1), c = 19.973(2) A, 0 = 91.56(1)°, V= 2028.7 Á

such calcula- tions have been extensively discussed (e.g., Droop 1987; Deer et al. 1997; Schumacher 1991, 1997). This paper presents the results of a study of upper mantle ferrikaersutite megacrysts hosted in scoria cones from the Harrat Ash Sham volcanic Þ eld (Fig. 1), using Mössbauer spectroscopy, H2O, and microprobe analysis. We then discuss the implications of the Þ ndings for the origin of these fer- rikaersutite megacrysts in relation to mantle oxygen fugacity and metasomatism. PETROGRAPHY The megacrysts and associated upper mantle xenoliths occur in
