492.5; Table 1) reflect the presence of calcite veins and development of minor calcite in the groundmass of these rocks.Outcrop samples. Outcrops are uncommon in the Potash Sulphur Springs Igneous Complex. Lithologies exposed in outcrops (Fig. 1) include carbonatites, syenites (including pulaskite, leucopulaskite, feldspathoidal syenite, malignite, nordsjoite, and naujaite), mafic rocks of the melteigite-ijolite series (including fasinite), and lamprophyre dikes. Wollastonite rock and an aegirine-wollastonite-miserite-rich rock (sample PSS-5, tentatively identified as a fenite) occur in the contact zone of the complex. Whole-rock analyses of outcrop samples are presented in Table 2.

“…The Magnet Cove Complex is one of numerous igneous intrusions in the region, some of which crop out and others of which are not exposed at the surface, but which have been sampled by deep drilling and (or) identified by gravity and magnetic surveys (e.g., McKeown, 1982;Hendricks, 1988; see Fig. 1 of Flohr and Howard, 1994, for a sketch map of the region that shows the locations of these intrusions).…”

“…Besides the surface exposures, gravity (Hendricks 1988) and magnetic (Hildenbrand 1985) data indicate the existence of large subsurface intrusions (although of uncertain lithology). Carbonatite, carbonatitepyroxenite breccias, pyroxenite, lamprophyre, serpentinized olivine-bearing pyroxenite/peridotite, and partly altered felsic rocks were encountered in drill holes in the central Arkansas area (Saline County;Flohr and Howard 1994).…”
