Stratigraphy
| Geological group: | Shindong | Formation: | Hasandong | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Previously, a Hauterivian-Barremian age for the Hasandong Formation was proposed, based on palynomorph assemblages (Choi, 1985; Choi, 1989; Yi et al. 1994). However, molluscan faunas suggest and Aptian-Albian age (Yang 1982) and Lee et al. 2018 SHRIMP and U-pb analyses provided a maximum depositional age of approximately 118+/-2.6Ma. The youngest detrital zircon ages were approximately 109Ma (Lee et al. 2010) | |||||
