From: A geophysical investigation of the fairy circles in Nebraska for geologic hydrogen exploration
Composite view of the spatial relationship between fairy circles and the potential source rocks images by magnetic susceptibility. The images related to the fairy circle in Fig. 10 are reproduced on the left. On the right, a set of fairy circles are overlaid on a 3D model of the inverted susceptibility viewed directly from the top. In the study area, there is no relationship between the presence of these surface features with deep source rocks.
