Global_Heritage_Stone_Resource
The Global Heritage Stone Resource (GHSR) designation seeks international recognition of natural stone resources that have achieved widespread utilisation in human culture. Details of the "Global Heritage Stone Resource" proposal were first provided publicly at the 33rd International Geological Congress in Oslo in August 2008. However, this initiative was suggested in 2007 to enrich an international acknowledgment of famous dimension stones.[1] At the same conference it was agreed to advance the GHSR proposal under the auspices of "Commission C-10 Building Stones and Ornamental Rocks" of the International Association for Engineering Geology and the Environment (IAEG). Since the Oslo conference the designation has also gained support from the International Union of Geological Sciences (IUGS).
