Global Heritage Stone: Towards International Recognition of Building and Ornamental Stones

This volume provides a synopsis of current research on volcanic processes, as gained through the use of palaeomagnetic and rock magnetic techniques. Thermoremanent magnetization information provides a powerful means of deciphering thermal processes in volcanic deposits, including estimating the emplacement temperature of pyroclastic deposits, which allows us to understand better the rates of cooling during eruption and transport. Anisotropy of magnetic susceptibility and anisotropy of remanence are used primarily to investigate rock fabrics and to quantify flow dynamics in dykes, lava flows, and pyroclastic deposits, as well as identify vent locations. Rock-magnetic characteristics allow correlation of volcanic deposits, but also provide means to date volcanic deposits and to understand better their cooling history. Because lava flows are typically good recorders of past magnetic fields, data from them allow understanding of changes in geomagnetic field directions and intensity, providing clues on the origin of Earth’s magnetic field.

Abstract
The proposal to designate those natural stones that have achieved widespread utilization in human culture was first mooted in late 2007, and first presented in a public forum at the 33rd International Geological Congress in July 2008. Over the next four years, a network of international correspondents was created, circulars were distributed, a website was established and formal rules were adopted, all with the focus of establishing the ‘Global Heritage Stone Resource’ designation. During the 34th International Geological Congress in July 2012, the Heritage Stone Task Group was formally established under the auspices of the International Union of Geological...
