Topic: Mapping Geologic Hydrogen Prospectivity in the Conterminous United States

​​​​​​​​​​​​​​​​​​

​​​​​​ABSTRACT: The geologic and geophysical inputs necessary for the favorability mapping of geologic hydrogen systems are presented here
in support of the U.S. Geological Survey's efforts to create the first map of geologic hydrogen prospectivity in the conterminous United
States. The geologic hydrogen system model has several components that are required for a viable accumulation: 1) a source of natural
hydrogen, 2) a reservoir to store hydrogen in the subsurface, and 3) a competent seal to retain the hydrogen and prevent leakage to the
Earth’s surface. In total, there are 21 geologic layers in the model and the distribution of chance of success values are assigned to each
layer based on our interpretation of the geologic hydrogen model and our comprehensive knowledge of the United States’ geology.


The geologic hydrogen source component is divided into three sub-components comprising serpentinization-type water reduction
sources (SP), radiolysis of water sources (RD), and deep mantle sources (DP). Layers within the SP sub-component include: 1) an area
defined by a magnetic anomaly in the offshore, eastern United States, 2) onshore areas where ultramafic rocks are present at the surface,
and are inferred to extend into the subsurface, and 3) deep subsurface areas that have high-amplitude, positive gravity anomalies. Layers
within the RD sub-component include 1) areas with known uranium deposits, 2) areas that are favorable for the concentration of uranium,
3) areas underlain by the Precambrian cratonic platform, and 4) areas that are underlain by accreted terranes and contain Phanerozoicage,
granitic rocks at the surface. Layers within the DP sub-component include 1) areas of mapped, km-depth scale surface faults, 2) areas
of Paleoproterozoic-age suture zones, and 3) areas of modeled, deep crustal boundaries interpreted from geophysical data. Finally,
migration pathways were applied to specific source component layers. Regional-scale hydrogen migration pathways are derived from the
basement topography, and consumption of hydrogen during migration is accounted for by diminished prospectivity with increased
migration distance.


The reservoirs and seal components are split between sedimentary (e.g., siliciclastic, carbonate) and crystalline rocks (e.g., igneous,
metamorphic) based on high-resolution, surface geologic maps of the United States. An additional seal layer accounts for areas where salt
is present within the subsurface. A final layer includes areas where sedimentary basins contain thick (i.e., >1,000 feet) accumulations of
both porous reservoir rocks and impermeable rocks for geologic hydrogen storage and seal, respectively.


Collectively, these layers comprise the geologic inputs for the first edition of a geologic hydrogen prospectivity map of the
conterminous United States.

MBGS ANNOUCES 2021-22 EZ MANOS SCHOLARSHIP WINNERS

Madeleline Tan, Undergrad Student, University of Michigan, Advisor: Jeroen Ritsema Title: Seismic Receiver function analysis of the Michigan Basin
The Michigan basin is an intracratonic basin approximately 400 km wide (Howell and Van der Pluijm, 1999). It is nearly circular, reaching the largest depth to the cratonic basin sequence in present day Saginaw Bay region. Previous receiver function analysis indicates Moho depth beneath the Michigan basin reaches 53 km, thinning out beneath its flanks (Moidaki et al., 2013; Shen et al., 2013). Stein et al., 2015 posit the Moho depth is on average 45 km beneath the Michigan basin, owing to the combined result of crustal thinning, post-rift volcanism, sediment loading, and basin inversion (Watts et al., 2018). My project focuses on new seismological constraints of the crustal structure beneath Michigan and the broader Great Lakes region using P-to-s receiver functions calculated from the recordings of distant (> 4,000 km) earthquakes at seismometers in Michigan. We will use USGS seismometers in the central US and U-M seismometers near Lake Erie (courtesy of Professor Yihe Huang) to measure variations of the thickness of the crust and sediments within and outside the Michigan Basin. New seismic analyses of the structure of the crust beneath Michigan and surrounding states will help place the Michigan Basin in a broader tectonic context and to constrain dynamic scenarios of its origin. 

Mathew Bell, Graduate Student, Western Michigan University, Advisor: Dr. Peter Voice Title: Dam Failure – Hydrogeologic Consequences and Effects on the Tittabawassee and Tobacco Rivers and the groundwater systems in Southern Gladwin County, Michigan

In May 2020, a reservoir dam at the intersection of the Tittabawassee and the Tobacco Rivers collapsed resulting in a cascade of hydrogeologic and hydrologic changes in southern Gladwin County, Michigan. Along the two rivers, replacement water wells drilled since the event have shown that the water table has dropped up to 6 meters. Recent LiDAR imagery shows the water surface along the two rivers and the reservoir lake also exhibit a 6-meter drop compared to records prior to the event. A combination of water well records (Wellogic Database and more recent drillers reports) and integrating validated oil and gas well records were used to construct sections and maps of the bedrock and glacial surface and water table elevations (prior to- and post-event), for bedrock, and glacial geologic units. In order to better define the county bedrock surface, Horizontal-to-Vertical Spectral Ratio (HVSR) passive seismic data was collected across the county study area to develop a regional contact. Well records and HVSR data better defines the bedrock surface in this region and will allow a better understanding of hydrogeologic connections between the glacial sediment cover and the underlying Paleozoic bedrock. Using calibrated passive seismic measurements, the bedrock surface is analyzed to determine the complexity of the bedrock surface and interaction with the glacial drift, which can determine if there are
separate glacial and bedrock aquifer systems. The bedrock surface mapping and cross sections can provide a context for how the groundwater from the glacial material interacts with the bedrock material below.

DOUGLASS HOUGHTON MEMORIAL

Douglass Houghton, Michigan’s first State Geologist, was honored on September 10, 2016 by
the placement of a State of Michigan Historical Marker commemorating his accomplishments. The
effort was led by Arlene Anderson‐Vincent, members of the Michigan Basin Geological Society,
Keweenaw County Historical Society and faculty at Western Michigan University and Michigan
Technological University. The dedication was incorporated into a MBGS field excursion led by
Professor Ted Bornhorst of Michigan Technological University and Lawrence Molloy, President of the Keweenaw County Historical Society. The two led a field excursion that covered the geology and history of sites from Houghton to Copper Harbor and wove a tale of the rise and fall of mining in the copper range. The field excursion included the dedication of the marker, which is located in Eagle River, Michigan at the Keweenaw County Historical Museum. The dedication had many speakers and a special appearance from Kyle Bagnall, who portrayed Bela Hubbard who told the story of Douglass Houghton’s 1840 expedition along Lake Superior. Douglass Houghton died in 1845 when the boat carrying himself and his crew capsized during a storm on Lake Superior near Eagle River.

     

  Michigan Basin Geological Society

​

The Michigan Basin Geological Society (MBGS) was founded in 1936 as an affiliated non-profit organization of the American Association of Petroleum Geologists (AAPG) to provide a forum for the exchange of ideas relating to the field of petroleum geology through field excursions and meetings.

​

Throughout the years, the role of the society has changed, and both meetings and field excursions now address a wide range of topics pertaining to the study of geology of Michigan and the great lakes area, and is open to anyone interested in geology.

​

MBGS has monthly meetings typically on the second Wednesday of each month from September through May. These meeting consist of a lecture on a wide variety of Michigan geology related topics. The meetings are open to all. The Executive Committee Officers meet prior to the meeting to discuss Society issues and is open to anyone interested in attending. The society has 1-3 geological field trips per year.

​

MBGS members are geologists, work in a geology related field, or are a geology student or hobbyist. The Society is dedicated to the advancement of the science of geology and related fields, disseminating knowledge of geology or related fields for the benefit of its members, and promoting the education of geology in Michigan. Annual dues are $35 per person and $10 per student.
