As a result of human activities such as mining and smelting of metalliferous ores, electroplating, gas exhaust, energy and fuel production, fertilizer and pesticide application, etc., metal pollution has become one of the most serious environmental problems today.

由于人类活动,例如采矿和金属矿石的冶炼,电镀,能源和燃料生产,肥料和杀虫剂应用,等等,金属污染变成今天最严重的环境问题之一。

Sulfur isotope measurements of deposits such as those in the 1.1 Ga Duluth Complex, the Per-mo-Triassic intrusions of the Noril'sk area, and the 1.4 Ga Kabanga intrusions provide evidence for the derivation of S from both sulfide-and sulfate-bearing country rocks. The 1.3 Ga Voisey's Bay deposit provides an example where δ^34 S values of the ores commonly fall within the accepted mantle range of 0±2‰, but detailed studies of Proterozoic metasedimentary country rocks show that their weighted average δ^34 S value is also within this range.

如1.1 Ga的Duluth杂岩、Noril'sk地区二叠-三叠纪侵入岩和1.4 Ga的Kabanga侵入岩体中矿床的硫同位素测定结果证明硫来自含硫化物和硫酸盐的围岩。1.3 Ga的Voisbey's Bay矿床矿石的硫同位素δ^34 S值通常落入公认的地幔硫同位素组成范围(0±2‰)内,而对其元古宙变质沉积围岩进行的详细研究结果显示δ^34 S的平均值也在此范围。
