Localities

There are two co-type localities, the Khaidarkan Sb-Hg deposit, Kadamjay District, Batken Region, Kyrgyzstan and the Kelyana Hg Deposit, Middle Kelyana River, North-Muya Range, Baunt District, Buryatia, Russia.

At the Carolina Mine, Landsberg, Obermoschel, Nordpfälzer Land, Donnersbergkreis, Rhineland-Palatinate, Germany, shakhovite occurs in oxidised mercury- and antimony- bearing tetrahedrite ore, associated with calomel, cinnabar, mercury, malachite and goethite (HOM).

At the Khaidarkan Sb-Hg deposit, Kadamjay District, Batken Region, Kyrgyzstan (one of the co-type deposits), shakhovite occurs in in the oxidation zone of cinnabar - livingstonite ore (HOM).

At the Kelyana Hg Deposit, Middle Kelyana River, North-Muya Range, Baunt District, Buryatia, Russia (one of the co-type deposits), shakhovite occurs as a late-stage secondary mineral in the oxidation zone of cinnabar-stibnite ore. Associated minerals include calomel, eglestonite, mercury, montroydite, terlinguaite, corderoite, kelyanite, kuznetsovite and antimony oxides (HOM).
