The 'Rock Room' is actually a suite of sample preparation rooms where field samples are processed, and thin sections, glass discs and pressed pellets are made. The facility is completely outfitted for thin section production, with diamond-tipped slab and rock saws, a series of grinding wheels, grit plates, polishing wheels, Vibromet vibrating polishers, and both MicroTrim seven-sample and MicroTec Mark II single-sample thin section machines. Additional equipment includes a hydraulic rock corer and hydraulic splitting maul, both large and small rock crushers, and a shatterbox assembly for powdering samples. The 'clean' room in this facility houses a three-sample Claisse Fluxy fluxer for preparation of glass discs, a Carver 12-ton hydraulic press for production of pressed pellets, and muffle furnaces for LOI procedures. Both students and faculty use these rooms extensively to prepare samples for a wide variety of research projects.
