Four methods to determine modal mineralogy were compared for three reference materials, STSD-1, LKSD-4, and TILL-1. These methods include ModAn, a normative calculation based on bulk chemical and mineralogical composition, X-ray diffraction analysis, and two scanning electron microscope techniques: feature image analysis and X-ray mapping. Results from each of the methods are reasonable and comparable; however, the choice of method must take into consideration their limitations such as need of bulk composition and mineralogy data to run ModAn; a detection limit of 2–3% of a mineral for XRD; automated X-ray beam positioning in feature image analysis; and extended processing time for X-ray mapping. 2001-E10 J.B.
