| 中文摘要: |
| 基性—超基性硫化物矿床是岩浆熔离作用的产物,其围岩蚀变通常不如热液矿床发育,以往研究普遍认为该类矿床元素分带特征不明显。在热液型矿床原生地球化学异常结构研究基础上,文章以新疆沙泉子基性—超基性岩铜镍硫化物矿为研究对象,对其原生地球化学异常分带特征进行了分析。研究结果表明,与热液型矿床相似,该矿床成矿元素Ni、Cu及伴生元素Co、Ag、As等形成的正异常不仅表现出十分明显的元素浓度分带现象,而且同时具有较为显著的元素分带特征,建立了沙泉子铜镍硫化物矿床元素分带序列:(As, Mo, Cl)—(Se, Ag, Bi)—(Te, Au, Co, S, Cu, Ni)。 |
| 英文摘要: |
| Formed by the magmatic liquation, there is no widely country rock alteration in the basic - ultra-basic type sulfide copper-nickel deposit as those in the hydrothermal copper deposit. The previous research showed that the element anomaly zoning of this type deposit is not obvious. The paper carried out the analysis of the primary anomaly zoning features of the Shaquanzi basic-ultra-basic type Cu-Ni sulfide deposit in Xinjiang, the results showed that the positive geochemical anomalies of ore-forming elements such as Ni, Cu and associated elements such as Co, Ag in the Shaquanzi deposit, not only have obvious zoning of element concentration, but also have obvious element zoning. Based on the study result, primary element zoning sequence is established within the deposit as followings:(As, Mo, Cl)-(Se, Ag, Bi)-(Te, Au, Co, S, Cu, Ni). |
