Formation of the French Variscan belt results from the punching of several
blocks that form at present the internal zones, by the Catalan Craton. Mont
agne Noire is located at the edge of this Catalan block, where transpressio
nal stresses predominate. The whole orogenic evolution of Montagne Noire, f
rom deep seated metamorphic nappes to doming and late wrenching, may be exp
lained in this transpressional context. ((C) 1999 Academie des sciences/Edi
