Abstract: Mineralogy, geochemistry, and high resolution zircon absolute dates of volcanic tuffs from the Upper Mississippian Barnett shale, the lower Permian Wolfcamp B, Wolfcamp A and lower Spraberry analyzed by both LA-ICPMS and CA-ID TIMS will be presented in this talk. The results are the first absolute dates in the Permian Basin, and they can help improve regional

stratigraphic correlations and basin modeling to assistant hydrocarbon explorations, and shed light on the correlation between the late Paleozoic North America regional time scale and the International Geological Time Scale. Comparing zircon CA-TIMS and LA ICPMS dates also has implications on minimizing dating cost with an acceptable age resolution.
