Abstract

This paper addresses one central issue of building stone research : an origin for calcium in gypsum formation in non-calcareous sandstones. A comparative study of Scrabo sandstone from outcrops and a 120-year-old building in central Belfast shows how weathering has significantly altered the mineralogy. Preliminary results suggest that the occurrence of gypsum throughout the stone blocks is related to chemical reactions between a pore-filling mineral, actinolite, and sulphur oxides from urban pollution. This study highlights the potential for future research into an internal mineralogical source of calcium for gypsum formation in building stones
