June 2019 | Searching for critical minerals in Michigan


          Examples of Michigan critical minerals

At the Michigan Geological Survey (MGS) and the Michigan Geological Repository for Research and Education (MGRRE), we are leaving no stone unturned in our search for minerals you may never have heard of, like sylvite, cesium, and manganese. Why?

Because America depends on resources like these, defined by the Department of the Interior as the 35 “critical minerals and rare earth elements.” But we are not producing enough of them. In fact, we are not producing any of some of the “rare earth elements.”  We import 90% or more of these minerals and elements—mostly from China.

And America’s dependence on foreign sources has increased dramatically. In the 1990’s, America was the world’s top minerals producer and exporter. Now we are the world’s top importer, making us increasingly vulnerable to supply shortages and price volatility.

Our newest research grant, from the U S Geological Survey, focuses on finding these minerals in Michigan. Dr. William Harrison, MGRRE Director, is leading a research team comprised of John A. Yellich, director of the Michigan Geological Survey; Dr. Peter J. Voice, research scientist and geologist; Dr. Joyashish Thakurta, economic geologist; Jennifer L. Trout, data manager; and several graduate and undergraduate students.

In a new NPR interview, Stateside discusses Michigan's role in mining these raw materials with Drs. William Harrison and Peter Voice. The interview begins at 18:40 or scroll down the NPR page for a shorter clip. 

APRIL 24, 2019 | EARTH DAY

Earth DayEarth DayOn April 24, MGRRE celebrated Earth Day with K-6th grade students in Lansing. Dr. Peter Voice brought mastodon and mammoth vertebrae and teeth to show the students. We shared resources from the Michigan Basin Geological Society, Michigan Geological Survey, the Department of Natural Resources, and the Department of Environment, Great Lakes, & Energy. We all showed examples of rocks and minerals, gave away samples including halite (generously donated by Detroit Salt), feldspar, coal, specular hematite, taconite pellets, native copper flakes, pieces of agate, and Petoskey stones. We demonstrated porosity and permeability with cores and bicycle pumps. Many students said our booth was their favorite. One student exclaimed, “I’ve been waiting for this all day!” and another said, “this is the start of my rock collection". We hope we inspired a few to pursue earth science.


MGRRE/MGS and the Michigan Oil and Gas Association presented a Petroleum Technology Transfer Council Workshop titled, "Field Redevelopment Opportunities" at the Grand Traverse Resort near Traverse City in partnership with MOGA. Eleven speakers gave presentations and 185 people attended.

Nov. 2018 | USGS Website highlights MGRRE's preservation work
Dr. William Harrison

Dr. William  Harrison and his team completed a USGS NGGDPP project to preserve and inventory cores and cuttings from our two major freshwater aquifers, aggregate materials, and other natural deposits. The USGS Website now shows our proposal for this project as the sample preservation proposal. Our potash core work is also shown as a preservation success story with an article about our work to preserve this world class source of a critical mineral.

Oct. 2018 | Wayne County bedrock map updated and natural resources and risks assessed

Using new sources of data and cores obtained largely from highway projects and other infrastructure development, Drs. William Harrison and Peter Voice with research colleagues Katharine Rose and Jennifer Trout reassessed the natural resources and geologic risks of Wayne County. They also revised the outdated county bedrock map through funding by the USGS STATEMAP program.

Their open-file report and revised map, showing the regional distribution of formations and resources provides insights into natural resources and structural characteristics of shallow geologic formations that are essential for future economic development and infrastructure improvements.

Aug. 8, 2016 | National Science Foundation award

Drs. Stephen Kaczmarek and Andrew Caruthers have received an award from the National Science Foundation to acquire a handheld X-ray fluorescence spectrometer which will be used to obtain geochemical data from cores archived at MGRRE. Acquisition of this new handheld X-ray fluorescence spectrometer is necessary in order to provide insight into the evolution of the Michigan Basin, which, in turn, will foster a better understanding of its geological systems and resources. Newly obtained data from these research endeavors will be used in joint academic-industry research partnerships regarding hydrocarbon reservoirs and other earth resources. Any insights gained into Michigan's geologic history will be shared with the K-12 community through MGRRE's Corekids outreach program.

As the Michigan satellite for the Petroleum Technology Transfer Council, MGRRE presented a workshop, co-sponsored by the Michigan Oil and Gas Association, on March 16, 2016, in Mt. Pleasant, Michigan. Approximately 135 members from industry, government and education attended to hear speakers discuss undiscovered oil and gas in Michigan, subsurface geological research by MGRRE faculty and students and the field experiences of industry members. Speakers included: Dr. Christopher Swezey, United Stated Geological Survey; Drs. William Harrison, Peter Voice and Andrew Caruthers, MGRRE; industry members Dean Bohjanen and John Fowler; and a panel of industry veterans, including Tim Baker, David Hall, Dave Maness, Lew Murray, Bill Quinlan, Rick Sandveit and Willian Strickler. Attendees also enjoyed poster presentations by MGRRE graduate students, Bryan Currie, Jonathan Garrett, Cameron Manche, Zaid Nadhim and Matthew Rine. A highlight of the event was the presentation of MGRRE's Lifetime Achievement Award to Core Energy President, Robert G. Mannes.

Jan. 22, 2016 | Additional racking constructed

Thanks to several generous donors from the oil and gas industry, MGRRE was able to add enough new racking in early 2016 to accommodate 150 more pallets of cores. Because we had very little archival space available last fall when we received some huge donations of core, we appealed to our donors to help us put up the new racking. They made it happen! Thank you to our donors and everyone who helped with the construction; now, we can archive and easily access these cores to use them in research and education.

Nov. 11, 2016 | New core collection

In late 2015, MGRRE was offered two large core collections that included about 30,000 feet of core. Most of these were drilled in southeastern Michigan, an area from which few subsurface samples were previously available. The newly drilled cores were donated by an engineering firm that drilled more than 230 boreholes through a seven mile long zone of shallow bedrock, including Antrim shale, the Traverse group and the Dundee limestone. These cores are in very good condition and hold raw data that can yield information for economic development and research when used by land-use planners, governmental agencies, academia, industry and developers.
