【 摘 要 】

Base rock selection is one of the major stages in the roofing granule process that determines profitability of the business and quality of the product. Detailed geological exploration, laboratory evaluations, and marketing considerations take place before the plant location receives an approval. A number of recommendations for choosing the proper base rock, based mainly on experience, have been developed by manufacturers over the last 50 years. The roofing granule industry developed the base rock tests to control quality of rock. However, the available information don't conform to some significant aspects of the rock specification. Additional research has to be done prior to geologic investigation in order to reduce the number of samples to be analyzed, time and cost of the deposits exploration.
