Two main structural types of Variscan syntectonic calcite veins were recognised during field work. Veins of Type I have an irregular or sigmoidal shape and are of ten arranged in enechelon arrays. A shearing regime during the formation of this type is deduced. Veins of a second structural type (Type II) have a more regular and straight shape relative to those of Type I and in some places form a dense net work. The structural position of the Type II veins is related to structural elements of Variscan folds. Veins were formed due to interlayer-slip combined with fold-related fracturing that gave rise to the infilling of dilational structures. A tensional regime also permits growth of the fibrous veins. Two principal directions were distinguished within the Type II veins. ER -
