This four-part publication series presents Mildner’s Geodynamic Reinterpretation Model at increasing levels of mathematical and geophysical depth. Part 1 (this document) provides the general conceptual and interdisciplinary framework. Parts 2–4 are companion documents and develop the cartometric, geophysical, and impact-mechanical foundations in quantitative detail.

Sven Mildner contends that the dramatic geodynamic and climatic rupture of 536 AD likely involved a reactivation of the ancient Caledonian Deformation Front (CDF) and the Trans-European Suture Zone (TESZ). He argues that large-scale inversion tectonics, fueled by Alpine compressive forces, reshaped Germania Magna during this period. With the Lausitz Block anchoring these stresses, neighboring massifs like the Harz and Thuringian Forest underwent significant rotation and deformation. The consequences were environmental and societal collapse: catastrophic floods, firestorms, and the formation of the 'Event-Dark-Earth' (ED-E) layer, alongside a major regression of the North Sea. This transformation explains why the ancient, compact shape of Germania Magna vanished, leading to the abrupt end of its settlement history.
