Join PBS-SEPM for an All-Virtual luncheon on December 15, 2020, beginning at 11:45 AM Central Time. As our Christmas present to members and the public, we are offering this event FREE. This month, the format will be VIRTUAL ONLY. Please sign up a couple of days early through www.pbs-sepm.org.

Zircon Absolute Dates of Late Paleozoic Volcanic Tuffs in the Midland Basin, West Texas

ABSTRACT: 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.
