Heritage Stones of the World: Introduction to the New Series

摘要

Heritage stones are those stones that have special significance to human culture, especially in the construction of historical buildings and monuments. The mandate of the Heritage Stone Task Group (HSTG) of the International Union of the Geo- logical Sciences is to draw attention to such stones, for many are no longer extracted but their historical quarries are linked to regional culture and local society, and should be preserved for conservation and restoration.
