É«É«À²

The Michigan Geological Repository for Research and Education at É«É«À² Michigan University is committed to preserving, researching and utilizing our collections of cores, samples and data for both educational and research purposes. These are essential to supporting economic development and providing societal benefits to our citizens. Currently, they are being used to provide geological information about our Critical Minerals and Rare Earth Elements, for which we are heavily dependent upon foreign sources. We are also committed to making these materials accessible both on-site and online:

• Core analyses
• Cores
• Cuttings
• Cuttings analyses for hydrocarbons
• Formation specific data
• Mudlogs and wireline logs
• Links to Lithological Log Strip Scans
• Potash Tops
• Analytical, pressure and production data
• Thin sections
• Well cores housed elsewhere
• ED-XRF Data
• Upper Peninsula core inventory
• Michigan Precambrian wells inventory - note that the lines highlighted in yellow are wells that have been cored
• Map of Michigan Precambrian wells showing wells with cores or cuttings
•  - See also the Research and Publications on left-most menu and click on "Minerals"
• Legacy Scout Tickets from Pure Oil Company

Disclaimer

Every effort is made to assure accuracy in our datasets. However, because of the number and size of our inventories, and because data has been entered by many people for a very long period of time, errors are unavoidable. As such, we continually check datasets when we use them in research and correct errors as soon as they are found. MGRRE provides this information as is and makes no guarantee or warranty concerning accuracy of the information contained in the datasets. Furthermore, MGRRE makes no warranties, either expressed or implied, as to the condition of the samples or of fitness of samples and data for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers at MGRRE, no warranty, expressed or implied, is made by MGRRE regarding the use of these data on any other system, nor does the fact of distribution constitute or imply any such warranty.

We always appreciate it when users let us know if they suspect an error or if they have difficulty opening any files. Please call us at (269) 387-8633 to report any concerns.
