东川和篦子沟铜矿床的硫同位素组成,作者在1978、1979年曾先后进行了介绍.指出两矿床的硫化物硫同位素组成可能与海水硫酸盐的还原作用有关.并认为这类矿床可以泛称为沉积变质矿床,不宜统称为火山一沉积变质铜矿床.最近,主张海底火山硫源的人对此提出了不同的看法和论据,而且这种探讨还涉及着我国前寒武纪几个著名铜矿床的硫源问题,因此,确有进一步讨论的必要.
The sulfur isotope composition of Dongchuan and Goupizou copper deposits was introduced by the author in 1978 and 1979. It is pointed out that the sulfur and sulfur isotopic composition of the two deposits may be related to the reduction of seawater sulphate and that such deposits can Generally referred to as sedimentary metamorphic deposits, should not be collectively referred to as volcano-sedimentary metamorphic copper deposits.Recently, people who advocate submarine volcano sulfur sources put forward different views and arguments, and this discussion also involves a few of the Precambrian The sulfur source of the famous copper deposit is therefore in need of further discussion.
