Mineral Transformations in Permafrost‐Affected Soils, North Kolyma Lowland, Russia
Soils in permafrost sediments were studied on the Kolyma Lowland, North‐East Siberia. Mineral transformations were studied by comparing samples from different geochemical positions relative to the permafrost table. The profiles studied are developed from Yedoma deposits (mid to late Pleistocene). Mi...
