为进一步探讨都龙锡锌多金属矿床的成矿物质来源,本文开展了硫、碳、氧同位素研究。结果表明,58件硫化物单矿物的δ~(34)S值变化小,靠近零值,具岩浆硫特性,说明该矿床的硫主要来自岩浆分异作用;23件含矿方解石样品的δ~(13)C值为-3.09‰~-8.57‰,均值-6.57‰,与岩浆碳同位素组成一致,且明显偏离大理岩分布范围。相对于早期含矿方解石,晚期不含矿方解石的δ~(13)C基本未变化,但δ~(18)O降低,显示后期有大气降水加入;大理岩的δ~(13)C值变化不大,近地表浅部的大理岩较深部、重结晶明显的大理岩的δ~(18)O更小。说明碳、氧主要来自岩浆,晚期则有大气降水的混合。 |

There are only a few reports regarding the source of ore-forming materials of the Dulong Sn-Zn polymetallic deposit, and their results are inconsistent. This paper systematically analyzed S-C-O isotopes of the ores to confirm ore-forming materials sources. The study suggested that S in the deposit came from magmatic differentiation, since the δ~(34)S values of 58 sulfide minerals, which are all closed to 0 with little variation, are similar to those of magma sulfurs; the δ~(13)C values of 23 calcite bearing ore minerals range from -3.09‰ to -8.57‰, with an average of -6.57‰, which are coincident with magma C isotope composition and deviate obliviously from the marble area. Compared with those of the early ore-containing-calcites, the δ~(13)C values change little in the late calcite, but the δ~(18)O values are lower, indicating precipitation was involved in the late stage; the δ~(13)C values of marbles change little, while the δ~(18)O values of deeper marble with clear recrystallization are remarkably lower. All of the above indicated that C and O mainly came from magma and mixed with precipitation in the late stage. |
