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 types of maps and map scales) is given in the Survey’s list of publications. Short report descriptions can be found on report landing pages, which are accessed through a publications search on the PaGEODE website.

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 a link, it will initiate the download of a ZIP file of 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.
