Changes in antimony isotopic composition as a tracer of
In this work, we investigated in situ isotopic compositions of antimony (Sb) minerals from two substages of the ore deposits near Pezinok (Slovakia). The δ123Sb values of the primary Sb minerals range from −0.4 and +0.8‰ and increase progressively along the precipitation sequence. In the substage II, the early-formed gudmundite …

Geology and Mineral Resources
Antimony is a soft, silvery metal with the chemical symbol Sb. It is used primarily in lead-acid batteries, and in metal alloys to increase strength, resistance to corrosion, and hardness. Antimony occurs in nature as the native element, but is more typically found in a wide variety of sulfide minerals including the main ore mineral stibnite (Sb 2 S 3).
