  • The structural charasteristics of fibrous vein of gypsum are described. Two types appears in this area: a syntaxial veins with parabolically-shaped, and other in 'double antitaxial perharps new model that it is proposed, with sigmoid-shape.

    Both indicate a reverse, overthrust-like relative movement. The geometry afld distribution of the structures indicate that events it is kept pace with a flexural-slip folds, during sorne phase post-0ligocene.
