A series of outcrops, on both banks of the Morávka river.

Contact of the Silesian and Subsilesian units of the Outer Western Carpathians.

Hradiště Formation clays, contact-metamorphosed (contact adinole) with strongly carbonatized and smectitized fragments of subaquatic volcanics.

Note: precise GPS coordinates not given in the abstract.

The most common alteration minerals are gypsum and fibroferrite.

Among the minerals listed is a potential Al-analogue of schwertmannite that could also be alumogel or an amorphous analogue of aluminite.
