The Raudfjellet ophiolite fragment, Central Norwegian Caledonides: principal lithological and structural features.
Roberts, David; Nilsson, Lars Petter; Ramsay, Donald M. (NGU Bulletin (445), Journal article, 2005)The Raudfjellet complex, Nord-Trøndelag, displays several of the features of a classical ophiolite pseudostratigraphy. At its base is a spectacular ultramafic mylonite. Elements represented include: (1) Ultramafic rocks, ... -
The structure and regional setting of the Skei Group, Leka, north-central Norway
Sturt, Brian A.; Ramsay, Donald M. (NGU Bulletin (426), Journal article, 1994)The unconformity between the metasedimentary Skei Group and subjacent ophiolite on Leka has important implications for the tectonostratigraphy of the region. As a distinctive marker horizon, it permits correlations within ...
