CHAUDIERE FORMATION
\nCHAUDIERE shale (changed to formation status) Paleocene (Trinidad, B W. I.).<\/p>\n
Author of name: RENZ (H. H.) (1942). Stratigraphy of North\u00acern South America, Trinidad and Barbados. Proc. 8th. Amer. Sci. Cong., vol. 4, p. 529.
\nType locality: Chaudiere River, Mt. Harris, Eastern Central Range.
\nThickness: About 2 000 feet.
\nThe stratigraphic equivalent of the Tarouba formation in the Central Range is the Chaudiere shale, n sequence of more than 1 000 feet of dense dark grey to olive-green, slightly silty shales in alternation with a few fine-grained grit layers. The Chaudiere shale contains an assemblage of foraminifera almost identical with that of the Upper Tarouba formation, consisting entirely of arenaceous species such as Rzehakina epigona var. lata and Spiroplectoides clotho.
\nThe Chaudiere shale is known to rest on Cretaceous and seemingly merges upwards into the Pointe-a-Pierre formation. The lower boundary is more or less disconformable and a con\u00acglomerate can occur which is related to the St. Joseph conglomerate at the base of WARING\u2019S Tarouba shale. SUTER (1951, P. 191) applies the term Chaudiere formation to the argillaceous facies of the Lizard Springs formation and KUGLR (1953, p. 39) stresses its Flysch character.
\nThe meeting of Pointe-a-Pierre (1955) has decided that the term Chaudiere shale should be changed to Chaudiere Formation<\/p>\n
