Geoheritage Meaning of Artificial Objects: Reporting Two New Examples from Russia

Abstract

Geoheritage is not necessarily linked genetically to “purely” geological processes. Investigations in two urban areas of Russia allowed us to find essentially artificial objects demonstrating certain geological uniqueness. The huge balls sculptured from rapakivi granite and installed in Saint Petersburg represent cultural, historical, and stone heritage. These are also artificial megaclasts with perfect sphericity. The coal waste heaps situated in Shakhty and its vicinity represent industrial, historical, and urban heritage. These are also artificial landforms creating a kind of pseudo-mountainous landscape. These examples permit us to question the importance of the co-occurrence of heritage categories for geosite assessment.
