The extensional gaps between the individual boudins may be rather long is some cases owing to brittle ductile deformation and these are the ones where the layers are actually thinned like necks and hence the term. The protracted stretching period may be in pulses that give rise to infill of these necks by calcite or quartz filling in the gaps as fibrous crystalline growth. Thus boudin necks are formed between lenses of competent material formed by elongation of interlayered competent/incompetent layers.
