Barite from Zigazinskaya dacha (Southern Urals)

Abstract

I found this mineral in its entirety in slightly rounded pebbles up to half a fist in size, consisting of barite with a small inclusion of leaded sheen, in the bed of the Narataya River, two miles southwest of the Narataevsky iron mine. The barite of these pebbles forms a medium-grained to coarse-grained aggregate, which is indivisible, often located, being elongated in one direction, so that a somewhat layered composition is formed.
