p.177: The Grindelwald ‘‘Marble’’ (‘‘Grindelwaldner Marmor’’, Arbenz 1909, Wieland 1976) outcrops in the valley of the lower Grindelwald glacier and is known for its use as building stone for door casings, columns and furniture tops. It is lens-like embedded in the limestone of the Öhrli Formation as colourful breccia. Components of Helvetischer Kieselkalk,Öhrli- and Quinten formations are enclosed by a sandy, dark-green or argillaceous, dark-red to violet matrix.

The Grindelwald ‘‘Marble’’ is considered as a breccia-variety of the Siderolithic Group; the less well known Rosenlaui ‘‘Marble’’ equally corresponds to a breccia-variety of the Siderolithic Group.
