Although pyrite overgrowth is the predominant cement that forms be- tween and within pyrite framboids (Figs. 3, 6, 8C, 8D), such spaces may also be filled with quartz. Although it is typically a minor constituent, in places quartz can actually form a matrix that surrounds pyrite crystals and holds them in place (Fig. 12).

Overview; Fingerprint; Abstract. Pyrite-based composite materials (Li/S) were prepared by high-energy ball milling of FeS 2 with one or more metal sulfides, Li 2 S, Cu 2 S, and CuS, in various molar ratios and under different conditions. Prolonged grinding resulted in the formation of mixed compounds rather than single-phase lithiated chalcopyrite.
