Soln\u00e9 kr\u00e1pn\u00edky tam vznikaj\u00ed v\u00a0m\u00edstech, kde do d\u016fln\u00edch prostor prosakuje slan\u00e1 voda z\u00a0nadlo\u017en\u00edch hornin.

\u201eVzorky jsme nasb\u00edrali p\u0159edev\u0161\u00edm proto, \u017ee dlouhodob\u011b pracujeme na kn\u00ed\u017ece o\u00a0miner\u00e1lech ostravsko-karvinsk\u00fdch dol\u016f. Kdy\u017e se ale kolega na jej\u00ed povrch pod\u00edval elektronov\u00fdm mikroskopem, uk\u00e1zalo se, \u017ee se na n\u011bm nach\u00e1z\u00ed doslova mineralogick\u00e1 zoo.

Miner\u00e1l je velmi mal\u00fd<\/p>\n

V\u00fdzkum trval pom\u011brn\u011b dlouho p\u0159edev\u0161\u00edm kv\u016fli nepatrn\u00fdm rozm\u011br\u016fm nov\u00e9ho miner\u00e1lu.

Poprv\u00e9 jej zaznamenal Dalibor Mat\u00fdsek z\u00a0V\u0160B-TUO p\u0159i studiu vzorku v\u00a0elektronov\u00e9m mikroskopu. Miner\u00e1l se nach\u00e1z\u00ed p\u0159\u00edmo na krystalech soli kamenn\u00e9.

\u201eAby mohl b\u00fdt nov\u00fd miner\u00e1l ofici\u00e1ln\u011b uzn\u00e1n, museli v\u011bdci spolehliv\u011b ur\u010dit jeho chemick\u00e9 slo\u017een\u00ed i\u00a0dal\u0161\u00ed vlastnosti.
