... ), outcropping at Monte Cavalluccio, Sacrofano, north of Rome. The host rock (“type-A” ejectum, Della Ventura et al. 1992 ) is composed of predominant sanidine and plagioclase (An ranging from 20 to 80%) with minor nepheline. Microscopically the rock shows a hornfels-like texture consisting of a skeleton...
