The production of dimension stones is well established in Thailand and the country has considerable processing capacities in the region, second only to China. The geological background of Thailand provides a huge potential of dimension stones, including magmatic, metamorphic and sedimentary rocks. The NE part of the country is made up by the Khorat Plateau with the main sandstone resources at its western margin. Metamorphic carbonate rocks are predominantly distributed along the border of a basin area in central Thailand. The western part of the country is characterized by magmatic belts that comprise the resources of igneous rocks. Large quantities of the dimension stone potential were used in the first part of the 1990s, when the domestic economy underwent a considerable upturn. The most important region for the production of granitoid rocks is the Tak batholith in northern Thailand. Therefore, the Tak granitoids are discussed as a case study with respect to petrophysical and depositional characteristics.

Building Stone Decay: From Diagnosis to Conservation
Stone buildings and monuments from the cultural centres of many of the world's urban areas. Frequently these areas are prone to high levels of atmospheric pollution that promote a variety of aggressive stone decay processes. Because of this, stone decay is now widely recognized as a severe threat to much of our cultural heritage. If this threat is to be successfully addressed it is essential that the symptoms of decay are clearly identified, that appropriate stone properties are accurately characterized and that decay processes are precisely identified. It is undoubtedly the case that successful conservation has to be underpinned by a comprehensive understanding of the causes of decay and the factors that control them. The accomplishment of these demanding goals requires an interdisciplinary approach based on co-operation between geologists, environmental scientists, chemists, material scientists, civil engineers, restorers and architects. In pursuit of this collaboration, this volume aims to strengthen the knowledge base dealing with the causes, consequences, prevention and solution of stone decay problems.
