Abstract
MAGNESIUM SILICATES IN MAGNESITE VEINS AT WIRY, LOWER SILESIA
Summary
Cerolile (saponite) and sepiolite have been found to occur in the magnesite veins in the mine at Wiry, Lower Silesia. Their occurrence points to a fact that the mineral composition of the magnesite veins of the deposit at Wiry is slightly different from that of the veins in the magnesite deposits at Grochowa, Braszowice and Sobótka. The author shortly describes the paragenetic magnesium silicates found in veins, i.e. talc, magnesium chlorite, cerolite and sepiolite. In the veins, these are irregularly scaterred, and are found in pores and in multiple fissures. The concentration of talc and of chlorite, as well as those of magnesite are thought to be of hydrothermal origin, whereas both veins and nests of cerolite and sepiolite, similarly as those of quartz and chalcedony, have been formed as a result of the exogenic processes active in the deposit.
