This table summaries the titanite and sphene reference materials commonly used in geochronology, listed in order of their age. Some of these materials have been reported to contain modest but significant levels of Pb-loss. Prior to considering the use of any of these materials for quality control purposes, it is strongly recommended that analysts carefully review the cited publications as well as other reports that may exist in the scientific literature. Compilations of zircon, apatite and monazite reference materials are also available.
