Bridging Analog and Digital: Tools and Interfaces from TUNB Project

Present-day challenges in geothermal research, sustainable exploration, and energy storage require detailed information on the geological setting of the deep subsurface, which should be at the same time easily accessible and understandable. Generalized vertical profiles serve as essential tools for using this information during various project phases, from initial planning to geological interpretation or resource estimation.

Our study presents one approach to developing such profiles for representative subareas (TK25, TK50) in sedimentary basins in Saxony-Anhalt. Stratigraphy, temperature, and lithofacies are systematically compiled in comprehensive data sets based on borehole data, historical maps, literature values, and recently published 3D parametrized volume models of the TUNB project.

To ensure broad accessibility and practical usability, an interactive map is implemented, serving both as a visualization tool and a simplified, user-friendly database. Users can select an area to view column profiles displaying stratigraphy, temperature gradients, and lithofacies distribution. Planned features include statistical summaries and an optional expansion with block diagrams highlighting geological features.

Our approach offers an efficient framework for utilizing and providing different types of geological data. It supports future research and other geological activities, and is adaptable to other regions and data types.
