تعیین مشخصات مقیاس میکروسکوپی ماسه سنگ ساختمان باستانی از ساکسونی (آلمان)

In a case study, mineralogical and technical properties of building sandstones from the Meißen cathedral (Saxony, Germany) were investigated and compared with material from potential historical source quarries. The results of the present study allowed to assign unequivocally historically used material to specific sandstone occurrences, and provide a comprehensive basis for the interpretation of weathering damage on the historical monuments. These data are useful for current conservation and reconstruction activities.
