Stratigraphy
Formation: | Kõrgessaare | ||||
Stratigraphy comments: Given that the position of the Tuhala Locality is in northern Estonia, it is most likely within the Kõrgessaare Fm. (see fig. 55 in Raukas & Teedumäe [eds.] 1997, Geology and Mineral Resources of Estonia, html version, http://sarv.gi.ee/geology);
The Vormsi Regional Stage is formerly known as the middle part of the "Lyckholm'sche Schicht" (Raukas & Teedumäe [eds.] 1997) |
Lithology and environment

Lithology description: The Kõrgessaare Fm. is composed of "bioclastic limestones" (Raukas & Teedumäe [eds.] 1997, Geology and Mineral Resources of Estonia, html version, http://sarv.gi.ee/geology) | |
Environment: | open shallow subtidal |
Geology comments: "North Estonian Confacies Belt at the northern flank of the Livonian Tongue" (Kröger & Isakar, 2006) |
