| Abstract: | The gold-bearing veins of the North Urals contain rare mineral selenium phases such as kawazulite, clausthalite, bohdanowiczite,
volynskite, soucekite, naumannite, and eucairite, new for this region. They are largely observed as the finest inclusions
in copper sulfides and closely associate with bismuth and tellurium minerals. Selenides were formed at the final oregenesis
stages. Selenium was likely taken from the host rocks in the course of hydrothermal metasomatic processes initiated by granite
intrusions. |
