The purpose of this report is to draw together known data on occurrences of stone, present production techniques and problems, types and varieties of available stone, markets, labor and land conditions, and the general potential of the stone industry in Arizona. Thus, the report is primarily an economic study. Data on building stone, landscaping stone, and crushed rock used in building for its decorative purpose are included; aggregate, ballast, rip rap, etc. are not included. Compilation of complete data on as widespread and varied an industry as this would probably be impractical at this time. Therefore, an annotated bibliography has been included; reference numbers in the text indicate items in the bibliography. Reference is also made to the state and federal agencies that can provide additional data. It is hoped that this report is sufficiently detailed to show basic trends, economics, and potential to both the present producers and those considering participation in this industry.
