Geological Library Catalog

The Oil, Gas, and Minerals Division has been gathering and disseminating information about Michigan’s non-renewable geologic resources since 1837. Much of the published materials about Michigan geology are out-of-print or difficult to access. This document is the result of an effort to make geologic information from agency publications available on the web. This is an ongoing project. 

This is a great listing of references and resources for students, teachers, and anyone else interested in better understanding Geology in Michigan. Learn about maps, minerals and mastodons just to name a few.  Most of the files are in Adobe PDF format. Type a keyword in the search box to get topics of interest to you.

The digital files are in Adobe PDF format. Files are based on either text or image files. Text files are presented in a consistent format with a table of contents and bookmarks as well as text searching. Image files are graphic based files which are not computer searchable. The digital files are good faith reproductions of the material presented for publication. The process used to generate the digital files has not included extensive editing for grammar, syntax, or punctuation. The digital files have been prepared from the best available copy. Original typographic and/or computer-based optical character recognition translation inconsistencies may persist. Errors and omissions are regrettable and unintended. Information such as names, addresses, prices, and the like were valid at the time of publication and may have changed. These digital versions express the views, opinions and interpretations of the authors. They do not necessarily reflect current thinking or do they necessarily reflect the position of the Oil, Gas, and Minerals Division or the Department of Environment, Great Lakes, and Energy. Interpretation and evaluation of the usefulness, accuracy and/or correlation with contemporary scientific doctrine is the responsibility of the reader.

A special acknowledgement and thanks to Jamie Bohr for her work and attention to the details that make the Digital Geology Library possible. Since the first version in 2005 with about 175 files, Ms. Bohr expanded the collection to over 1,500 files.
