The geochemical Phenomenon-Local geochemical fields in a glacier (scientific note)
Geochemical fields in alpine cold and warm glaciers were studied. Local geochemical fields of typomorphic elements were found to form in the ice and on the surface of glaciers overlying ore bodies and endogenic geochemical haloes. The formation of local cryogenic geochemical fields in the glaciers r...

| Summary: | Geochemical fields in alpine cold and warm glaciers were studied. Local geochemical fields of typomorphic elements were found to form in the ice and on the surface of glaciers overlying ore bodies and endogenic geochemical haloes. The formation of local cryogenic geochemical fields in the glaciers results from sharp geochemical heterogeneity and geochemical processes in underlying rocks which cause cryogenic migration of chemical elements and compounds in the glacier. The thickness of geochemical fields, (134m) is limited by ice thickness in the studied glaciers. |
