General Geology Reports
Description: Below is a list of general geology reports published by the Pennsylvania Geological Survey. These publications cover a variety of topics, including stratigraphy, paleontology, mineralogy, speleology, and areal geology. More detailed bibliographic information (including the types of maps and map scales found in some of these reports) is given in the Survey’s list of publications, Pennsylvania Geological Publications.
Disclaimer: Each user is responsible for the appropriate application of Pennsylvania Geological Survey reports and data as explained in our official disclaimer.
Availability: If a title in the list below is an active link, clicking the title will initiate the download of a ZIP file that was prepared for the report. Reports that include mineral or fossil collecting sites on private property and the locations of undeveloped caves were not prepared for online distribution. Useful material from Fossil Collecting in Pennsylvania (G 40) that does not include such sensitive information can be viewed on the Fossils page of our website.
The published printed copies of general geology reports can be borrowed from the Survey library or possibly from one of our repository libraries. If you are not near one of these libraries, you can go to a local library and ask the librarian to arrange an interlibrary loan.
