Moreover, the distribution and relationships of regional lithostratigraphical units corresponding to the Hirnantian in southern Estonia and Latvia (Kuldiga and Saldus formations, and Bernati, Edole, Piltene, and Broceni members) are still insufficiently understood.
The Porkuni Stage encompasses the Kuldiga and Saldus formations, both of which are subdivided into two members: Bernati and Edole, and Piltene and Broceni, respectively (Fig.
