Abstrakt: | Inside smoky and black crystals of quartz from joint fractures in bituminous Famennian limestones at Łag6w in the Holy Cross. Mts, there occur inclusions containing variable amount of bituminous matter and aqueous solution of salts and gas. The occurrence of bitumen gives quartz its colour. The average temperatures of smoky quartz crystallization were c. 70oC, and of black quartz - c. 160-190OC. The veinlets of brown-black calcite, containing analogous inclusions, crystallized under similar conditions which revealed ., both minerals being connected with aqueous solutions containing dispersed droplets of bituminous matter. |
