摘要

摘要: 新疆蒙西铜矿床具有良好的成矿前景, 被视为准葛尔盆地东部最有前景的铜矿床之一。通过对矿区内岩石中元素富集贫化规律及原生异常分带的研究发现, 蒙西铜矿床中存在着多属性地球化学异常, 既有成矿元素、成矿伴生元素及矿化剂元素形成的正异常, 又有稀有元素等发生贫化形成的负异常, 成矿信息极其丰富。贫化元素形成的负异常比富集元素形成的正异常空间展布范围更大, 矿床整体产于贫化元素形成的负异常中。富集元素形成的正异常不仅表现出十分明显的元素浓度分带现象, 同时具有较为显著的元素组分分带特征, 建立了蒙西铜矿床原生异常分带序列:[(Au), Bi, Cd]—[Sb, Ag, Hg]—S—[Mo, Cu, (Au)], 为矿区深部及外围找矿工作提供了依据。

Abstract: Mengxi copper deposit is regarded as one of the best metallogenic prospects copper deposits in Xinjiang east junggar.In this paper, element enrichment and depletion regularity and primary anomaly zoning sequence were studied.The results show that there exist positive anomalies of ore-forming and associated elements and mineralizer elements and negative anomalies of Nb in the ore deposit.The space distribution range of negative anomaly formed by depleted elements than the positive anomaly formed by enriched elements is bigger, and the whole deposit occurs in a depletion halo formed by the negative anomalies.The major indicator elements of the Mengxi copper deposit not only have obvious elements concentration zoning, but also have element zoning characteristics.Primary anomaly zoning sequence is established: [(Au), Bi , Cd]-[Sb , Ag, Hg]-S-[Mo, Cu, (Au)]。The result obtained by the authors provides a basis for the prospecting work in the depth and the periphery of the ore district.
