【 摘 要 】

This thesis describes a new set of procedures for evaluating dimension stone potential. It focuses on the granitic rocks of the Arabian Shield. In particular, two sites near Hail have been assessed in detail. Site 1 is in the Jibal Aja batholith, and site 2 is in the Jabal Salma pluton. Conventional investigation methods -- desk study, field and laboratory measurement -- have been applied, along with an analysis of satellite imagery. A key element in the new set of procedures is the use of Landsat (Thematic Mapper) data in the form of false-colour, CRC images. Many aspects of the sites which are related to the suitability of the materials for dimension stone can be recognized via the Landsat images; these include rock type, state of alteration and staining, rock colour, rock-unit contact conditions, and distribution of weathering. A new method of predicting in-situ block sizes has been developed which takes its input from conventional scanline data. From all of the geotechnical information collected, and the engineering geological maps which have been constructed, summary maps are prepared showing the distribution of potential dimension stone resources in the two test sites.
