目前人们认为,矿床中的硫至少来自下列来源之一,即: 1.直接由地壳初始岩浆冷却而沉积的初生硫; 2.在地壳最上部带的沉积或结晶岩层中形成的沉积硫; 3.沉积岩层变质或熔融时分离出的再生硫。 下面我们将根据矿床的硫同位素成分来讨论上述来源的某些特征。 初生硫 产在地壳深部或上地幔的岩石可能是初生硫的来源。组成这些岩石的矿物成分从未参与沉
At present, it is believed that sulfur in the deposit comes from at least one of the following sources: 1. Primary sulfur deposited directly from the initial crustal cooling of the earth’s crust; 2. Deposited sulfur formed in sedimentary or crystalline strata in the uppermost crust of the crust; 3 Regenerated Sulfur Separation When Sedimentary Rocks Are Degenerated or Melted. In the following, we will discuss some of the above sources based on the sulfur isotopic composition of the deposit. Primary sulfur production Rocks in the deep crust or upper mantle may be sources of primary sulfur. The mineral components that make up these rocks have never been involved in sinking
