Abstract
The results of an investigation of the graptolitic shale of Llandovery age along Øleå on Bornholm are presented. A section through the shale is made and the thickness of the Llandovery Series estimated to be between 110 and 130 m. 15 bentonite layers are reported. A revised zonation is proposed and discussed. The Llandovery Series comprises the Rastrites Shale and the lower part of the Cyrtograptus Shale. No marked transition is observed between the two shales and the subdivision of the Llandovery Series is abandoned.
