High Resolution SHRIMP Phosphate U-Pb Ages in Sayh Al Uhaymir 169: Possible Age of the Pre-Imbrium Impact
Abstract
The phosphates in SaU-169 U-Pb system were analyzed using a SHRIMP IIe-Mc, Combined with the ratios of U/Pb from Single-collector and Pb/Pb from Multi-collector, This study yielded two impact ages of 3915.4 ± 5.2Ma and 3940 ± 3.5Ma.
