Abstract
Seventy-seven Telychian bentonite samples from six drill-core sections were correlated on the basis of their sanidine composition. In total, bentonites from 43 volcanic eruptions, of which six are new discoveries, were established in the Telychian of Estonia. Names and identification (ID) codes were assigned to the bentonites. The different distribution patterns of volcanic ash thicknesses indicate different source volcanoes. Lack of several bentonites near the transition between the Rumba and Velise formations and at the Llandovery-Wenlock boundary indicates sedimentary hiatuses in the eastern part of the studied area.
