(2013) :
Tectonics of the Lepontine Alps : ductile thrusting and folding in the deepest tetonic levels of the Central Alps. Swiss Journal of Geosciences, 106/3, 427-450
p.433: The very heterogeneous zone of para- and orthogneisses, amphibolites, meta-gabbros, ultramafites, calcschists and marbles of the Bombogno unit continue to the south into the similar Isorno zone. Wieland (1966) observed the continuity between the Isorno and Orselina zones across the Masera syncline, an observation that has been confirmed by Bigioggero et al. (1981a, b) and Steck (2008).
