Stratotüübidholostratotüüp: Kunda karjääri puurauk (14.00..88.30 m) | Mens & Pirrus, 1977 | KirjeldusFrom Mens, K., & Pirrus, E. (1997): The Lontova Formation was identified in the rank of formation by Männil in 1958 (Männil 1958a). Its type section in the Kunda quarry has been selected for the stratotype of the Lontova Stage. The formation occurs in northern, eastern and central Estonia, and is westwards laterally replaced by the Voosi Formation. The Lontova Formation is represented by greenish-grey and variegated argillaceous rocks with interbeds of coarse- to fine-grained sandstone in the lowermost and fine-grained sandstones in the uppermost part. The formation is subdivided in ascending order into the Sämi, Mahu, Kestla and Tammneeme members (Kala et al. 1970, Mens & Pirrus 1977). The Sämi Member consists of alternating sandstones and argillaceous rocks containing glauconite and, occasionally, also flattened phosphatized pebbles. The Mahu Member is made up of greenish-grey sandy or silty claystones with thin interlayers of sandstone. The Kestla Member is characterized by homogenous multicoloured claystones with greenish‑grey, reddish‑brown and purplish interbeds, strips and spots. The admixture of sandy material is limited. The Tammneeme Member consists of fine‑grained sandstones and greenish‑grey claystones and occurs in a limited area. ViitedMeidla, T. 2017.
