Mineral Industries


According to the U.S. Geological Survey’s Minerals Yearbook, in 2011 the total value of Pennsylvania’s nonfuel-mineral production was $1.60 billion, placing Pennsylvania 13th in the nation. More specifically, Pennsylvania ranked second among the states in the production of crushed stone, fourth for tripoli, sixth for lime, seventh for portland cement, seventh for masonry cement, and 12th for common clay.

The Pennsylvania Geological Survey has published many reports pertaining to its mineral industry, as evidenced by the list of titles on our Mineral Resource Reports web page. Some selected favorites are described below.

The Nonfuel Mineral Resources of Pennsylvania. This educational series booklet (ES 12) is an introductory overview of the mineral-resources industry in Pennsylvania, past and present. It covers both the nonmetallic resources that continue to be an important industry in our state as well as the metallic resources, such as iron, lead, zinc, and chromium, that were important in Pennsylvania from the 18th century through the middle of the 20th century.

Directory of Nonfuel-Mineral Producers in Pennsylvania. Open-File Mineral Resource Report 15–01.0 is a tabular-formatted PDF publication that contains detailed information from mining companies about the locations of their extraction operations, the rocks that are being mined, and the products that are derived from those rocks. The data in the directory can also be accessed through an interactive map.

Geology and Mineralogy of Uranium and Thorium in the Reading Prong of Berks, Lehigh, and Northampton Counties, Pennsylvania. Although once eagerly sought in the United States, uranium deposits in Pennsylvania are no longer mined. There is now more environmental concern for uranium's detrimental effects than desire for its commercial value. Deposits of uranium and thorium have been found in various parts of the state, including the Reading Prong region. Mineral Resource Report 97 provides detailed information about the extent and nature of the deposits in that region, including maps and analytical data. The information presented in this 2014 report is based on a study that was completed in 1980.

46th Forum on the Geology of Industrial Minerals. The annual international forum on the geology of industrial minerals was hosted by the Pennsylvania Geological Survey in 2010 and focused primarily on industrial minerals in the state. This publication is a booklet of abstracts and a field-trip guide from that forum.

Atlas of Pennsylvania’s Mineral Resources. This four-part atlas is Mineral Resource Report 50. It contains analytical data and maps covering limestone and dolomite, clays and shales, and metals.
