Hontoria’s stone (Burgos, Spain): Characteristics and weathering

This paper deals with petrological and petrophysical features of the Hontaria's stone, Burgos (Spain), with which many important monuments were built in northern Spain, in orderr to establish a basis for individual monument restoration. The study contains an historical reference to sorne buildings in which this stone was employed, geological considerations of the origin area, laboratory analysis of the samples, and results of the most common characterization tests. As a conclusion, it can be stated that the Hontoria's stone is apure limestone, with good mechanical and hydrological behaviour, resistent to weathering, easy to quarry (underground mining) and with large resources
