Stratigraphy
Formation: | Tongchuan | Member: | 2 | ||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: Member 2 of the Tongchuan Formation; Tongchuan Formation disconformably overlies the Ermaying Formation. Member II of the Tongchuan Formation has been radioisotopically dated at 238.6 ± 2.6 Ma and 234.6 ± 6.5 Ma using SHRIMP U-Pb analyses [31]. This suggests a Ladinian to Carnian age |
