Fig. 4. Location of Hg-containing gas deposit Oposhyna. /-4 deep faults of different direction; 5
Oposhnya; 6-8 isolines in proximity to strong earthquakes
showed the existence of long mercury anomalies above the faults in this part of
the Karpinsky lineament.
We studied in more detail the Mirnensk ore deposit among those of the
Stavropol uplift. Its high mercury potential is stipulated by the regional positionin the crossing conjunction of longitudinal faults of the southern flank of the
