ПРИРОДА ЗАБАРВЛЕННЯ КАЛIЙНО-МАГНIЄВИХ СОЛЕЙ ПЕРЕДКАРПАТТЯ

Анотація

Nature of the Precarpathian potassium-magnesium salts colour with the help of X-ray
and spectrophotometric methods have been studied with chemical, spectral and micro-
chemical data using. Red colour of the carnallite, sylvite and polyhalite as had been ascer-
tained is conditioned by goethite and hematite admixtures while yellow colour of the
leonite and astrakhanite – by jarosite ones. The most probable reasons of the langbeinite
and halite violet colour are metallic sodium colloid particles (had been formed under the
radioactive radiation of potassium), manganese admixtures and atomic centres presence.
Increased iron and manganese contents in potassium-magnesium salts are connected with
underground waters transported into salt bearing Precarpathian foredeep basin along
faults in Miocene epoch.
