Abstract

Boudinage and apparent stretching lineations result from extension parallel to layering in deformed rocks, and may be related to the states of finite and infinitesimal strain. Patterns of development of these extensional features are examined in relation to folding with the fold axis (?) parallel to the Y-axis of the strain ellipsoid, and it is shown that they can develop either normal or parallel to ?. Two examples of more general cases where ? is oblique to Y are also considered. A new moolel for double boudinage is suggested based on the development of boudins in two different orientations during progressive deformation.
