| Environment: | open shallow subtidal |
| Geology comments: "North Estonian Confacies Belt at the northern flank of the Livonian Tongue" (Kröger & Isakar, 2006).
"Rhythmically bedded argillaceous wackestones–packstones of the Haljala Stage have been deposited in the temperate climate open marine conditions on the upper shelf or ramp (Nestor & Einasto 1997). The abundance and high diversity of benthic shelly fauna refers to the depositional environment at a moderate depth, probably within the photic zone." Ainsaar & Meidla (2004, Abstracts and Field Guide volume of WOGOGOB-2004 8th Meeting on the Working Group on the Ordovician Geology of Baltoscandia [http://www.gi.ee/WOGOGOB/wogogob_web.pdf]) | |
