Background

During the 13th International Symposium on the Ordovician System in Novosibirsk, Russia, in July 2019, the next meeting was proposed, and agreed by the delegates, to take place in Estonia in 2023. It will be after 41 years and 10 meetings that the major event for all friends of the Ordovician System will return to Baltica. The last time was in August 1982 in Norway, organised by Prof. David Bruton and his colleagues from the Palaeontological Museum in Oslo. Over 150 scientists from 22 countries attended the meeting back then and we expect no less participants for the upcoming event in 2023.

Estonia is an appropriate place for an Ordovician meeting as the Ordovician rocks occur throughout the country and crop out within 1/3 of its territory. The conference venue, the capital city Tallinn, is largely located on Ordovician strata and its medieval old town is built from the Middle Ordovician limestone (which, by the way, is the national stone in Estonia) and belongs to the UNESCO World Heritage. The Ordovician rocks of Estonia have been attracting geology students since the early 18th Century and the rich and well-preserved fossil record has made the region renowned worldwide. Together with the neighbouring Baltoscandian countries, Estonia has continued to serve as one of the model areas for Ordovician studies and welcomes you in July 2023!

Conference

The scientific sessions are planned to take place in the Estonian Academy of Sciences, located in Toompea Hill in historical centre of Tallinn (address: Kohtu 6), within walking distance of various hotels, restaurants, and the Baltic Sea. Depending on the number of participants the venue may be subject to change.

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 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 Orovician 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). A variety of hotels and other types of accommodation is available at https://booking.com with a price range from EUR 50 to EUR 200 per night.

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.

About Estonia

Estonia is located in northern Europe between Finland, Russia, Latvia and Sweden. With an area of 45,000 km² and a population of ca 1.3 million, it is one of the smallest countries in Europe. The official language is Estonian, a Fenno-Ugric language spoken by 1.1 million people. Estonia is a member of the European Union, the Eurozone, NATO, the OECD, and the Schengen Visa Area.

Estonia is renowned for its economic and social freedom, sound education system, high level of digitisation and government e-services. The capital of Estonia is Tallinn, famous for its UNESCO World Heritage medieval old town. Tartu, the second largest city in the country, is best known for its university, established in 1632.

Travel

Tallinn can be reached from many European cities by direct flights or via nearby larger airports, particularly Helsinki, Stockholm and Riga. From Scandinavia and Central Europe, Estonia is also reachable by car or bus. For details, please consult: https://www.visitestonia.com/en/travel-here-around/travel-to-estonia
