Geologic Publications and Data
The Pennsylvania Geological Survey has been collecting and disseminating geologic and topographic data since the First Pennsylvania Geological Survey was formed during 1836.
Over the years, hundreds of reports and maps were printed and published, many in cooperation with the U.S. Geological Survey. The current (fourth) series of publications includes printed and digital products, mostly technical but also many popular and educational in scope.
statewide geologic map and gis dataSETS
Probably the survey’s most popular group of datasets, Bedrock Geology of Pennsylvania (ZIP) is a 1:250,000-scale statewide coverage consisting of ArcGIS shapefiles for geologic units, geologic contacts, dikes, and faults. These datasets were created and slightly modified from the source materials used for Map 1, Geologic Map of Pennsylvania (ZIP).
Pennsylvania Geology Magazine
Pennsylvania Geology is a free online magazine published by the DCNR Bureau of Topographic and Geologic Survey. It includes articles on the geology of Pennsylvania, earth science education, and topographic mapping, and announcements of new publications, conferences, and other geologic and topographic items of interest.
To receive a hyperlink to each new issue as it becomes available, email the Pennsylvania Geological Survey. To view past editions of the magazine, use the hyperlinks provided in this list of magazine volumes (PDF).
Obtaining Geological Publications
The Fourth Pennsylvania Geological Survey assigns reports to different publication series according to their content, technical complexity, and intended audience. These publications are available as ZIP or PDF files.
Pennsylvania Geological Survey Publications (ZIP) contains descriptions of each series, individual report information, and hyperlinks to publications. Publications can also be selected and downloaded through geographical searches on PaGEODE.
Almost all formal Pennsylvania Geological Survey publications can be borrowed from the survey library or through an interlibrary loan.
In addition to being available online or in libraries, free publications that are still in print may be ordered from the Pennsylvania Geological Survey by email. These include most of the:
- Educational series booklets
- Park guides (now part of the the trail of geology series)
- Page-size maps
- Poster maps
- Information circulars
When emailing your request, please include:
- The publication series and number abbreviation
- The quantity you desire
- The ship-to address
- A telephone number where you can be reached if necessary
- If requesting classroom quantities, please provide the school affiliation

Databases and GIS Datasets
GIS datasets are included with many of the geologic maps and reports released since the year 2000.
Databases exist for the following:
PaGEODE Web-Mapping Application
PaGEODE stands for Pennsylvania GEOlogic Data Exploration. In addition to the publication-searching capability mentioned above, it can be used for geographical searches of Pennsylvania Geological Survey data. With PaGEODE, GIS datasets related to bedrock or surficial geology, mineral resources, or geologic hazards can be viewed in your web browser and downloaded for specified areas.
