The availability of newsletter has now been extended back to 1981. The pre-1993 newsletters are available as documents combining all newsletters for an entire year. Please enjoy reading about the good old times and PGK history.
A very big thank you to Youri Poslaswky for collecting these documents through the years and sharing them with us for posterity.

Lecture: Devonian-Carboniferous back-arc extension in Avalonia and its impact on 350Ma of Southern North Sea Basin evolution by Jeroen Smit
Basin Analysis is critically dependent on a priori assumptions on deeper crustal and lithospheric structure and composition. This applies in particular to studies that aim at quantitative assessments of basin maturation, in depth understanding of long-lived and repeatedly active fault zones and (upper) crustal segmentation. These all demand precise outlines of terranes and continents, their margin's geometry and (post) accretion history. This is quite challenging when the basement is currently located in the middle of continents and covered by deep basins such as the Southern North Sea Basin.
The Devonian-Early Carboniferous was a period of intense rifting in the Avalonia microplate in between the Caledonian and the Hercynian-Alleghanian collision phases. This rifting phase created the typical horst-and-graben structure of much of the Southern North Sea. In the Southern North Sea, the Netherlands and northwest Germany, the Late Devonian-Early Carboniferous rift structure and units are obliterated by the thick cover of Late Carboniferous-to-Recent basin fill and by the recurrent fault reactivation. Although this rifting set the stage for 350 Ma of basin evolution, its dynamics remains relatively unknown. Major open questions include the mode and total amount of extension as well as the age and origin of the Central Graben and the relation between structures located east and west of it.
In this project, we are addressing these issues by integrating existing data from lithosphere to basin scales and a map-view restoration. We have revised the crustal map of the Thor Suture Zone. The newly defined northern margin of Avalonia and the Thor Suture Zone are key elements in the reconstruction of Devonian-Carboniferous rifting of Avalonian lithosphere. We propose a revised map of Devonian-Carboniferous basin structures including the main horsts and grabens and the governing faults east of the Central Graben.
Based on these maps, we present a new paleo-tectonic reconstruction and a novel geodynamic scenario for the Devonian- Carboniferous rifting. These findings are key for better understanding of long-lived tectonic compartmentalisation and post-rifting deformation phases.
