“韦尔贝尔4”岩心（韦尔贝尔背斜，最西端的莱茵地块）记录了从碳酸盐-硅质混合的晚法门期（“斯特鲁期”）斜坡到图尔奈期碳酸盐台地、维先期钙质浊积岩台地斜坡的发展，以及最后在维先期形成一个深的、黑色明矾页岩充填的前陆盆地。长期趋势受华力西造山带的控制。这种趋势受到短期海平面波动的调制，其中包括导致Hangenberg危机、中期图尔奈期加深事件、晚期图尔奈期的一次重大侵蚀不整合以及阿斯比安-布里甘阶边界的一个明显层序边界。
The core “Velbert 4” (Velbert anticline, westernmost Rhenish Massif) records the development from a mixed carbonate–siliciclastic late Famennian (“Strunian”) ramp to a Tournaisian carbonate platform, a Visean calciturbiditic platform slope, and finally the installation of a deep, black alum shale-filled foreland basin during the latest Visean. The long-term trend was controlled by the advancing Variscan orogeny. The trend was modulated by short-term sea-level fluctuations, which among others caused the Hangenberg crisis, the mid-Tournaisian deepening event, a major erosional unconformity during the late Tournaisian, and a pronounced sequence boundary at the Asbian–Brigantian boundary.
