Geology and structures of the Røstvangen sulphide deposit in the Kvikne district, Central Norwegian Caledonides

The Røstvangen mine occurs in a sequence of regionally metamorphosed sedimentary rocks and volcanic greenstones belonging to the Caledonides of central Norway. It is presumed to be of Carnbrian age. The dose spatial relationship between the greenstone and sulphide deposits in the Kvikne district in general suggests that the ore material was originally brought into the geological milieu from depth during the period of submarine volcanic activity. The structural control of the Røstvangen ore bodies indicates that a later remobilization, transport and subsequent redeposition of the sulphides in the present fold hinge position took place during Caledonian metamorphism and foldings.
