I´m doing a reserach about the Toarcian Deposition of Baltica/Fennoscandia. I´m looking for decent data to compare the Ciechocinek Formation with it´s regional equivalent, the Lava Formation, altrougth i didn´t find any decent data about sedimentology outside superficial references, that talk about the Jotvingiai Group as a whole. I was first looking for a series of texts where is cited more in depht:

- Grigelis, A. 1994a. Jura. In: Lietuvos geologija. Grigelis, A. & Kadūnas, V. (eds.). Mokslo ir enciklopedijų leidykla, Vilnius, 139-153 [in Lithuanian].

-Simkevicius, P., 1998. Jurassic of the SE Baltic: Lithology and Clay Minerals. Lithuanian Institute of Geology, Vilnius

And outside that, any paper that covers in depth Lithology, Sedimentology and Fossils from the Formation will be welcome.
