a larger blastic force, built between halite blasts euhedrally formed blasts, in the form of
elongated poles and slats, several to about a dozen millimetres long, laid in parallel to the
contact area with salt, created the directional- at- parallel texture (Fig. 7F). Inside the rock,
in the zone of limited freedom of recrystallization, anhydrite grains with similar blastesis
power formed a granoblastic structure composed of anhedral blasts (Fig. 7E). Flat-paralleldirectional
texture of the anhydrite rock was a clear symptom of recrystallization under pressure,
resulting from halotectonic processes.

Close to the anhydrite block boundaries, there appeared epigenetic brous halite veins
and several centimetre long, epigenetic crystal halite nests, with milky-greenish ne-crystalline
polyhalite.
