Defining Midcontinent Rift geologic hydrogen potential
As a geophysicist, I am intrigued by the potential to use gravity combined with aeromagnetic data to better define the details of the internal and surrounding tectonic environment of the midcontinent rift. From the analogy with other rifts and the EARS, the MCR should contain volcanoes/intrusives and other complex features both syn-rift and in adjacent areas. Intersections/offsets in the rift segments are likely areas of more complicated structural patterns. Existing coarsely gridded aeromagnetic data provide glimpses of some of the complexity in certain areas of the rift. More densely collected data could revolutionize the detailed understanding of the fine scale development of the rift (internal/external areas). Understanding this complexity could allow one to focus on areas that are likely more highly intruded and faulted and thus more highly faulted/fractured. This is important knowledge for defining migration pathways for fluids. I have tried to be conservative with my interpreta…
