- Аннотация: A study of soil gases was made in North Carolina (USA) in and around morphological depressions called “Carolinabays.” This type of depression is observed over the Atlantic coastal plains of the USA, but their origin remainsdebated. Significant concentrations of molecular hydrogen (H2) were detected, notably around the bays. Thesemeasurements suggest that Carolina bays are the surficial expression of fluid flow pathways for hydrogen gasmoving from depth to the surface. The potential mechanisms of H2 production and transport and the geologicalcontrols on the fluid migration pathways are discussed, with reference to the hypothesis that Carolina bays are theresult of local collapses caused by the alteration of rock along the deep pathways of H2 migrating towards thesurface. The present H2 seepages are comparable to those in similar structures previously observed in the EastEuropean craton.Keywords: Hydrogen; Seepage; Carolina bays
