Abstract
Iowa's mineral resources have been valued and utilized by its residents ever since man began to inhabit this area of North America. Early explorers recognized many of these resources, and they soon became the economic base for settlement of many areas in the state. By the middle of the 20th century mineral deposits were being extracted in all regions of Iowa. In recent years total production has continued to increase, with 1978 marking an all-time high in the value of minerals produced in the state. Today, on-going research suggests that other recoverable mineral resources lay deep beneath the surface. With increasing world demand, and with proper planning and state guidance, Iowa's potential deep resources could contribute to the supply of materials needed to sustain our rapidly expanding, technological society.
