December Luncheon Meeting


About The Event


High resolution zircons absolute dates of volcanic tuffs from the Lower Pennsylvanian Atoka, the Lower Permian Wolfcamp B, Wolfcamp A, and Lower Sprayberry analyzed by both LA-ICPMS and CA-ID-TIMS will be reported by this talk. The results are the first absolute dates in the Permian Basin and they can help improve regional stratigraphic correlations for the Late Paleozoic time 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 how to better determine zircon LA-ICPMS maximum depositional ages.
