International Uranium Resources Evaluation Project (IUREP) national favourability studies: Sikkim

Sikkim is a country in the eastern Himalayas and is bound on the west by Nepal, on the north by Tibet, on the east by Bhutan and on the south by India. Precambrian Darjeeling gneiss forms the rim of the amphitheatre while schists of Late Precambrian to Lower Paleozoic rocks form tee habital interior. A small outcrop of carboniferous to Permain methomorphic rocks is preserved in the Tista Basin as well in a thin outcrop trust upon fluvitile beds of Sivalik which is mostly of Pliestocene age. Imbricate thrusts have stacked the rocks in a vast heap where reverse metamorphism is common. Ni information is available concerning uranium occurrences and resources as well as past and present explorations. The uranium potential of Sikkim is almost zero
