广东大宝山矿田船肚钼钨铜矿床的地质特征、成矿规律与找矿方向

广东大宝山矿田船肚矽卡岩型钨钼铜矿床受船肚花岗闪长岩体接触带的控制,按空间展布分为北矿带和南矿带。浅部钻探和坑道揭露显示:北矿带裂隙密集,由石英网脉型、构造破碎带型及少量矽卡岩型铜钼矿组成;南矿带为矽卡岩型钨钼矿。蚀变特征和矿化类型及成岩成矿年龄表明,该钼钨矿床是与燕山期花岗闪长岩浆活动有关的中高温热液充填交代矿床,成矿物质来源于花岗闪长岩。通过对有利的赋矿围岩分析、控矿构造解析和与大宝山矿区的控矿要素对比分析,认为船肚岩体是沿着寒武系(顶板)与泥盆系(底板)之间的推覆构造侵入的,靠近花岗闪长岩的内接触带是石英网脉型辉钼矿的有利找矿部位,而云英岩化则是有效的找矿标志。在深部和外围矽卡岩带是船肚矿区南、北矿带探寻矽卡岩型钼钨矿体最具潜力的部位。船肚北矿带次英安斑岩体内部、与斑岩体相连通的成矿前断裂带中和构造虚脱部位、块状和似层状矿体外围的断层、裂隙、节理连通部位及层间滑动虚脱部位都是下一步铜多金属矿找矿的有利部位。文章认为船肚矿区深部存在隐伏铜钼多金属矿体的潜力较大,是大宝山多金属矿田找矿突破的重点地段和重要接替资源区域。

Genesis of the giant Zijinshan epithermal Cu-Au and Luoboling porphyry Cu–Mo deposits in the Zijinshan ore district,Fujian Province,SE China: A multi-isotope and trace element investigation

The Zijinshan ore district occurs as one of the largest porphyry-epithermal Cu–Au–Mo ore systems in South China, including the giant Zijinshan epithermal Cu–Au deposit and the large Luoboling porphyry Cu–Mo deposit. The mineralization is intimately related to Late Mesozoic large-scale tectono-magmatic and hydrothermal events. The Cu–Au–Mo mineralization occurs around intermediate-felsic volcanic rocks and hypabyssal porphyry intrusions. In this study, we summarize previously available Re–Os isotopes, zircon U–Pb age and trace elements, and Sr–Nd–Pb isotope data, and present new Pb–S and Re–Os isotope data and zircon trace elements data for ore-related granitoids from the Zijinshan high-sulfidation epithermal Cu–Au deposit and the Luoboling porphyry Cu–Mo deposit, in an attempt to explore the relationship between the two ore systems for a better understanding of their geneses. The ore-bearing porphyritic dacite from the Zijinshan deposit shows a zircon U-Pb age of 108–106 Ma and has higher zircon Ce⁴⁺/Ce³⁺ ratios (92–1568, average 609) but lower Ti-in-zircon temperatures (588–753 °C, average 666 °C) when compared with the barren intrusions in the Zijinshan ore district. Relative to the Zijinshan porphyritic dacite, the ore-bearing granodiorite porphyry from the Luoboling deposit show a slightly younger zircon U–Pb age of 103 Ma, but has similar or even higher zircon Ce⁴⁺/Ce³⁺ ratios (213–2621, average 786) and similar Ti-in-zircon temperatures (595–752 °C, average 675 °C). These data suggest that the ore-bearing magmatic rocks crystallized from relatively oxidized and hydrous magmas. Combined with the high rhenium contents (78.6–451 ppm) of molybdenites, the Pb and S isotopic compositions of magmatic feldspars and sulfides suggest that the porphyry and ore-forming materials in the Luoboling Cu–Mo deposit mainly originated from an enriched mantle source. In contrast, the ore-bearing porphyritic dacite in the Zijinshan Cu–Au deposit might be derived from crustal materials mixing with the Cathaysia enriched mantle. The fact that the Zijinshan Cu–Au deposit and the Luoboling Cu–Mo deposit show different origin of ore-forming materials and slightly different metallogenic timing indicates that these two deposits may have been formed from two separate magmatic-hydrothermal systems. Crustal materials might provide the dominant Cu and Au in the Zijinshan epithermal deposit. Cu and Au show vertical zoning and different fertility because the gold transports at low oxygen fugacity and precipitates during the decreasing of temperature, pressure and changing of pH conditions. It is suggested that there is a large Cu–Mo potential for the deeper part of the Zijinshan epithermal Cu–Au deposit, where further deep drilling and exploration are encouraged.     

隐伏斑岩铜矿区微细粒土壤地球化学特征及其找矿指示意义-以福建罗卜岭铜钼矿为例

在风化壳覆盖区应用传统化探方法和矿物地球化学找矿方法开展斑岩型矿床深部找矿存在一定制约。土壤微细粒分离测量技术是一种可应用于覆盖区找矿的穿透性地球化学勘查技术,在干旱地区已取得良好的应用效果,亟需开展多景观、多矿种应用试验。基于此,本文选择为红土风化壳覆盖的福建省罗卜岭斑岩铜钼矿为研究区,开展风化壳土壤微细粒分离测量技术有效性实验。结果显示,与不含矿酸性岩体风化壳相比,研究区明显富集铜钼矿成矿及伴生元素,尤其是Mo、Cu、Au显著富集,与此同时,含矿岩体风化壳中元素变异系数较低,符合斑岩型矿床元素含量富集系数高、变异系数低的典型特征。元素空间分布特征与矿化蚀变、断裂构造、地形演化密切相关。Cu-Mo异常可以圈定矿化中心蚀变带,V、Hg则在外蚀变带富集。Cu与Mo在研究区西北部的分异指示了紫金山矿田由SE向NW主成矿作用由Cu-Mo演变为Cu-Au。元素剖面分布特征进一步验证了成矿蚀变、地形演化对元素分布的控制作用。地形演化决定了蚀变带在地表的分布,进而控制元素的分布。罗卜岭铜钼矿体呈马鞍状分布于古背斜两翼,在后期风化剥蚀作用下,背斜核部演化为负地形,使得中心蚀变带接近出露地表,表现为Cu的正异常;古背斜两翼现今为正地形,矿体埋深较大,前缘晕元素Hg表现为正异常。因子分析结果很好地展示了元素的组合与分异特征。总体上,可以根据Cu-Mo异常判断矿体中心位置,根据Hg判断矿体埋深,根据Sn、V、Cr等识别花岗闪长斑岩体边界。本研究系统证明微细粒土壤测量在风化壳覆盖区探测隐伏斑岩铜钼矿的有效性。     

Two periods of mineralization in Xiaoxinancha Au–Cu deposit,NE China: evidences from the geology and geochronology

The Xiaoxinancha Au–Cu deposit is located at the eastern segment of the Tianshan–Xingmeng orogenic belt in northeast China. The deposit includes porphyry Au–Cu orebodies, veined Au–Cu orebodies and veined Mo mineralizations. All of them occur within the diorite intrusion. The Late Permian diorite, Late Triassic granodiorite, Early Cretaceous granite and granite porphyry are developed in the ore area. The studies on geological features show that the porphyry Au–Cu mineralization is related to the Late Permian diorite intrusion. New geochronologic data for the Xiaoxinancha porphyry Au–Cu deposit yield Permian crystallization zircon U–Pb age of 257 ± 3 Ma for the diorite that hosts the Au–Cu mineralization. Six molybdenite samples from quartz + molybdenite veins imposed on the porphyry Au–Cu orebodies yield an isochron age of 110.3 ± 1.5 Ma. The ages of the molybdenites coeval to zircon ages of the granite within the errors suggest that the Mo mineralization was genetically related to the Early Cretaceous granite intrusion. The formation of the diorite and the related Au–Cu mineralization were caused by the partial melting of the subduction slab during the Late Palaeozoic palaeo‐Asia Ocean tectonic stage. The Re contents and Re–Os isotopic data indicate that the crustal resource is dominated for the Mo mineralization during the Cretaceous extensional setting caused by the roll‐back of the palaeo‐Pacific plate.

五子骑龙矿床——被改造的斑岩铜矿上部带

五子骑龙矿床产于紫金山矿田的一个早白垩世火山管道旁侧。火山管道中充填的英安斑岩向深部逐渐相变为花岗闪长斑岩。由于后期断裂的破坏，该花岗闪长斑岩及其矿化系统被上冲到与五子骑龙矿床相邻的中寮矿床近地表位置，从而形成斑岩型铜矿床－中寮矿床。五子骑龙矿床中，环绕英安斑岩发育明矾石化、迪开石化、埃洛石化和红柱石化蚀变，这些蚀变是改造并叠加早期绢英岩化蚀变的结果。其铜矿石中的铜蓝、硫砷铜矿和蓝辉铜矿，也经常交     

Copper isotopic compositions of the Zijinshan high-sulfidation epithermal Cu–Au deposit,South China: Implications for deposit origin

The Zijinshan high-sulfidation epithermal Cu–Au deposit is located in the Zijinshan ore field of South China, comprising porphyry–epithermal Cu–Au–Mo–Ag ore systems. The Cu ore body is more than 1000 m thick and is characterized by an assemblage of digenite–covellite–enargite–alunite. Digenite is the dominant Cu-bearing mineral, which makes this deposit unique, although the mechanisms of digenite formation remain controversial. To elucidate the genesis of digenite, this paper presents the Cu isotopic compositions of Cu-sulfides in the Zijinshan high-sulfidation Cu–Au deposit. The Cu isotopic values (⁶⁵Cu relative to NIST 976) of all samples range from −2.97‰ to +0.34‰, and most values fall in a narrow range from −0.49‰ to +0.34‰, which is similar to the Cu isotopic signature of typical porphyry systems. Copper isotope ratios of each mineral decrease with increasing depth, a trend that is also typical of porphyry deposits. The variation tendency of δ⁶⁵Cu values between sulfides is consistent with the sequence of mineral formation. These observations suggest that the Cu-sulfides in the Zijinshan Cu–Au deposit have a hypogene origin.     

湖北大冶铜山口铜(钼)矿床中钨矿化特征及其地质意义

为了查明鄂东矿集区内铜山口矽卡岩-斑岩型铜(钼)矿床中钨矿化作用的地质特征.对该矿床中的钨矿(化)体开展了系统的矿床地质特征、岩石学和矿物学研究,并探讨基底对区内钨矿在空间上分布的影响.钨矿体主要产出于花岗闪长斑岩与碳酸盐岩地层的接触部位及其附近,其产状受接触面形态的控制;钨既可形成独立的钨矿体,也可作为铜和钼矿体的伴生组分;钨矿物主要为含Mo的白钨矿.铜山口矿床中的钨矿化与矽卡岩化有着密切的时间、空间和成因联系,具有典型的氧化性矽卡岩型钨矿特征,钨和铜矿化是同一岩浆-热液事件不同阶段的产物,但钨矿体的产出位置比铜矿化相对更深;鄂东矿集区南部的钨矿化岩体具有很多相似性,他们很可能在一定程度上受富含铜和钨的江南式基底控制,江南式和董岭式基底在鄂东矿集区的结合部位可能位于阳新岩体附近.     

Mineralization,alteration, structure,and Re–Os age of the Lanjiagou porphyry Mo deposit,North China Craton

Lanjiagou is a porphyry Mo deposit in terms of its alteration zonation and mineralization associated with granitic intrusions and predominance of quartz vein-hosted molybdenum mineralization. It is the largest Mo deposit in North China Craton (404,000 t). There is an intimate spatial/temporal association between all stages of mineralization and Early Jurassic granitic intrusions at Lanjiagou. Most of the molybdenum was emplaced during the principal hydrothermal (PH) stage (184.6 ± 1.3 – 185.6 ± 1.4 Ma), contemporaneously with intrusion of fine-grained porphyritic granite (188.9 ± 1.2 Ma) into a granite batholith (193 ± 3 Ma). The PH mineralization stage is mainly hosted by a quartz-dominated stockwork associated with phyllic alteration in the fine-grained porphyritic granite. This stage was followed by the late hydrothermal (LH) activity. Thick Mo-rich quartz veins were emplaced during the LH stage and cut the porphyry ore bodies. A ring breccia zone formed during the last hydrothermal stage and apparently cuts both the porphyry and the quartz vein ore bodies. The main hydrothermal vein stages have predominantly concentric and radial vein orientations centred on the ring breccia zone. Most of the concentric veins have shallow dips, whereas the radial veins are subvertical. The LH veins have predominantly NEE and NW orientations in the deposit and are moderately inclined. We surmise that the veining was controlled by the local stress regime generated by the intrusion of a large, deep pluton that we interpreted to be the source of the granites, the breccia zone, and the molybdenum mineralization. Resurgence within the magma chamber reactivated the steep concentric structures in a reverse sense, and accumulation of magmatic and/or fluid pressure resulted in explosive brecciation, producing the ring breccia zone. A predominantly late set of NW-trending, post-ore felsic dikes, associated with the regional structures, are a consequence of far-field stresses exceeding local stresses in the deposit.
