The Chilgog Formation (Korean칠곡층; Hanja漆谷層; RRChilgok-cheung), also known as the Chilgok Formation, is an Early Cretaceous geologic formation in South Korea. Formerly dated to the Berriasian to Hauterivian, later dating has established an Albian age.[2] Dinosaur remains from this formation[3] are actually from the Iljig Formation, which correlates with the lower part of the Chilgog Formation.[4][5]

Description

[edit | edit source]

The formation predominantly consists of sandstone, mudstone and conglomerate, with subordinate tuff and other volcanics.[6] It overlies the Jinju Formation and underlies the Silla Conglomerate, which underlies the Haman Formation, respectively.
