『Abstract
　Weathering processes and intensity vary according to the predominant environmental conditions as well as the rock's physical and geotechnical properties in a given are. Jedburgh Abbey Church has been taken as a representative historical building constructed from Carboniferous Old Red sandstone at humid pre-glacial region. The research aims to examine weathering processes and intensity under the environmental conditions of high relative humidity and low temperature, and to determine the output of weathering through an examination of the rock's petrological and geotechnical properties.
　Thin section study, scanning electron microscope and X-ray fluorescence techniques have been used to examine the rock's petrography and mineralogy on one hand and to determine weathering products on a microscale on the other hand. It is noted that the Carboniferous Old Red Sandstone has a quartz arenite texture with iron oxide and dolomite within its texture, authigenic clays are also detected. Pitting of quartz grains, exfoliation of silica overgrowth and fragmentation of the rock's feldspar can be noted on a microscale resulting in recession of the rock's components cohesion.
　The geotechnical results indicated variation in the physical nature of the construction rock from inside to outside the church with recession from the former to the latter due to weathering. The great reduction in mortar and the rock's calcium oxide and high content of both sulphur and chlorine from inside to outside the church is a result of weathering and deposition of air pollutants on the stone's surface on the outdoor surfaces. Chemical weathering, e.g. salt hydration and chemical alteration of the rock's carbonate content to sulphate and chloride salts is expected to dominate in the study area at such conditions of low temperature and high relative humidity accompanied with air pollutants.』
