in conjunction with 

The 3rd Annual Meeting of IGCP 735 and 
STRATI-2023 Ordovician Excursion

Excursions

The conference will be preceded by an excursion in Estonia introducing all classic Ordovician successions in the eastern Baltic region and a post-conference field trip in Sweden (organised by Jan Ove Ebbestad, Uppsala University). The pre-conference excursion is also an official excursion of the STRATI-2023 Conference. Please note that the number of places is limited on both excursions. The places are reserved in the order of registration and kept only if the fee is paid before April 1, 2023.

This is the end. Ordovician-Silurian boundary beds in the Reinu quarry, central Estonia.

The pre-conference excursion will visit, among other stops, the Reinu limestone quarry near Rapla, which is a new outcrop of the Hirnantian Stage and the Ordovician-Silurian boundary in Estonia.

Pre-conference excursion: Ordovician of Estonia (July 15-18, 2023)

The 4-days excursion will focus on the Ordovician succession of northern and central Estonia. The cost is EUR 300 (includes bus travel, field lunches, excursion guidebook). The maximum number of participants is limited to 60. Please note that participants are responsible for arranging accommodation for the entire period of the excursion in Tallinn. 

The stops to be visited include coastal cliffs exposing uppermost Cambrian to Upper Ordovician siliciclastics and limestones, and active quarries and opencast mines for limestone and oil shale. Additionally, selected drill cores from central and southern Estonia piercing the entire Ordovician sequence will be shown at the Geological Survey's core study facility. 

Post-conference excursion: Ordovician in Sweden (July 23-26, 2023)

The 4-days excursion will focus on the Ordovician successions of Västergötland (southwest of Sweden) and the Siljan district (central Sweden). The preliminary cost is EUR 600 (includes bus travel, four field lunches, three dinners, and accommodation for three days during the field excursion) and late price EUR 700. The maximum number of participants is limited to 45. The excursion will start from Uppsala, and please note that participants are responsible for arranging accommodation for the day before the excursion (22 to 23 July) and the day/days following the excursion (26 July onwards).

The field trip to Västergötland (two days) will include Mt Kinnekulle with the condensed Middle Ordovician limestone succession, and the Hirnantian at Mt Billingen. Some highlights in the Siljan district (two days) include type sections for several of the Swedish Ordovician units and the famous Boda Limestone carbonate mounds.
