Dear Wojtek,
try the following two references. I guess they are the first to speak about
delta-porphyroclasts. On the other hand, I wouldn't recommend to use the
term "opposite kinematic indicators" for them, because they are not
"opposite". They are just somewhat unusual...
Van Den Driessche, J. (1986). Structures d'enroulement et sens de
cisaillement. Exemples et modèles. C. R. Acad. Sc. Paris 303: 413-418.
Van Den Driessche, J. and J. P. Brun (1987). Rolling structures at large
shear strain. J. Struct. Geol. 9(5/6): 691-704.
Ahoj,
Pavel
