SHRIMP U-Pb geochronologic data for zircon and titanite from Mesoproterozoic rocks of the St. Francois Mountains terrane, southeast Missouri, U.S.A. These data are for a regional geochronologic study of Mesoproterozoic rocks in the St. Francois Mountains, southeast Missouri. Zircon, plus one sample of titanite, from fifty samples of metaigneous rocks were dated by sensitive high resolution ion microprobe (SHRIMP).
