Comblanchien lies in the
Côte d'Or escarpment. The
Jurassic limestone of the
Côte includes a pink-veined marble called
Pierre de Comblanchien which was laid down in the
Bathonian epoch. The stone has characteristics similar to those of marble and is notable for the variety of its shades of colour, the pink of bindweed (
Convolvulus) and
beige. Its veining harmonizes with any decorative style. It is not susceptible to
frost damage, is fine-grained and capable of accepting a polish. It may be slippery if used polished, as a flooring. Its most notable use was in
l'Opéra in Paris. The
quarries lie in the
Côte overlooking Route Nationale 74, north and south of the village and similar stones are found in other places along the same vein. ==History==
