Multi-Period Ore Exploitation in Upper Silesia, Central Europe

Abstract

ABSTRACT We studied the abandoned mining field in southern Poland using high-resolution lidar images to distinguish the number of mining shaft remains and their morphological diversity. We identified 13,864 remains of mining shafts of various sizes (2–30 m in diameter) and diverse levels of denudation. This allowed us to select 13 mining shafts for detailed study. The radiocarbon dating of charcoal and peat from the shafts indicate three phases of exploitation in the study area: the Roman and early migration period (2nd century b.c.–6th century a.d.), the Middle Ages (6th–14th century a.d.), and the modern period (15th–17th century a.d.). The data on metal ore exploitation in the European Barbaricum is scarce and, in the study area itself, historical written sources indicate the onset of mining only in the 12th century a.d. Therefore, ore exploitation in the study area during the Roman period and early migration period, as well as in the early Middle Ages, is an unexpected result.
