Massive Sulphide Deposits Related to the Volcano-Passive Continental Margin in the Altay Region

Acta Geologica Sinica(English Edition) 1999年第3期73卷 253-263页

The Devonian volcano-passive continental margin in southern Altay is a significant volcanogenic massive sulphide metallogenic belt. Acidic volcanism has been dominant on the inner side of the volcano-passive continental margin, i.e., near the old land, resulting in a Pb-Zn metallogenic sub-belt, in which the ore deposits are hosted by sedimentary rocks in volcanic series, as represented by the large Koktal Pb-Zn deposits. In the central part of the margin far away from the old land, bimodal volcanic formations are well developed, forming volcanics-hosted Cu-Zn metallogenic sub-belts, e.g., the large-scale Ashele Cu-Zn deposit. The Qiaoxiahala sub-belt on the outer side of the margin near the ocean ridge is located at the spreading central trough, where ophiolite suites are developed. This type of deposits is rich in gold and copper, similar to the Cyprus-type Fe-Cu-Au metallogenic sub-belt in metallogenic environment (represented by the Qiaoxiahala medium-scale Fe-Cu-Au deposit). From the old land to the ocean, the mineralizing age becomes younger, i.e., from Early Devonian→Early and Middle Devonian→Middle Devonian, forming a complete metallogenic zoning series on the volcano-passive continental margin. Comparative studies show that the massive sulphide deposits distributed on the volcano-passive continental margin are different from those formed under a plate subduction regime and oceanic ridge environment; the former have their unique features and wide distributions, representing a new type of volcanogenic massive sulphide deposits—the Altay type.

Types, Metallogenic Environments and Characteristics of Temporal and Spatial Distribution of Copper Deposits in China

Acta Geologica Sinica(English Edition) 1989年第1期63卷 79-92页

Based upon a comprehensive study of 123 copper deposits in China. this paper reaches the following conclusions: 1. The crust in China was solidified pretty late; with the accretion of the plate, the copper mineralization moved towards its margin in space and became successively younger in age. 2. The major copper ore types ever found in the world have mostly been discovered in China, in which the porphyry type seems to be the most important and the massive sulfide type in the transitional bed between marine clastic and carbonate rocks is clearly defined. 3. Carbonate strata are widespread in China and their deposition lasted for a long geological period, so the proportion of copper deposits occurring in them is large as compared with other parts of the world. 4. Seven metallogenic epochs can be recognized, in which the Mesozoic one plays the leading role and the middle(late) Palaeozoic and Cenozoic ones are next in importance. Mineralization was comparatively simple in the early geological period. and became diversified later on. In the early epochs copper deposits related to basaltic magmatism and metamorphosed marine sediments predominated, whereas in the later epochs those related to granitic magmatism and continental sedimentation were dominant. 5. There exist in China thirteen metallogenic provinces, of which the Lower Yangtze downwarping belt, Sanjiang fold system, Jiangnan axis and Xikang-Yunnan axis are of greater significance. 6. The crustal mobility in China was rather pronounced, the polycyclic evolution of the crust has resulted in such obvious phenomena as the inheritance of mineralization, the coexistence of various types and the superposition of different genetic types.

Rare Earth Element Behaviour in theWunugetushan Copper - Molybdenum Deposit,Inner Mongolia, and Its Implications

引用

Acta Geologica Sinica(English Edition) 1994年第2期68卷 153-167页

作者： qin kezhang and Wang ZhitianBeijing Institute of Geology for M ineral Resources, CNNC, Beijing Beijing Institute of Geology for Mineral Resources CNNC Beijing

Considering porphyry and wall rocks as a whole system, the behaviour of rare earth elements (REE) in hydrothermal alteration and mineralization of the exceedingly large Wunugetushan porphyry Cu-Mo deposit of Inner Mongolia has been studied. It has been found for the first time that there exists complementary REE variation in hydrothermal alteration between porphyry and wall rocks, and Eu depletion has certain significance in indicating mineralization. Based on an analysis of the variation in REE contents of relevant minerals during the hydrothermal alteration, the ore-forming fluids are inferred to be depleted in ∑REE, comparatively enriched in ∑Y and strongly depleted in Eu. In the intermediate-strong alteration zones, porphyry and wall rock took part in hydrothermal metasomatism and alteration almost in equal ratio mass. Furthermore, studies of REE and hydrogen and oxygen isotopes and fluid inclusions confirm the existence of hydrothermal convection and the possibility of supplying part of ore materials by the wall rock and indicate that the application of REE geochemistry in mineral prospecting is promising.

Over the last ten years China has made dramatic progress in exploration and ore discoveries in the Tibetan Plateau(Fig.1).These mineral deposits are associated with Mesozoic Tethys oceanic subduction and Cenozoic India—Eurasia continental collision. Because of this distinctive tectonic evolution,the geology and mineralization are complex and diverse. However,the metallogenesis under two different settings is poorly understood so far,due to short exploration history and lack of systematic *** framework includes four principal mineralization

Olivine Compositional Mapping of Mafic-Ultramafic Complexes in Eastern Xinjiang(NW China):Implications for Cu-Ni Mineralization and Tectonic Dynamics

引用

Journal of Earth Science 2012年第1期23卷 41-53页

作者： Benxun Su kezhang qin He Sun Dongmei Tang qinghua Xiao Pingping Liu Patrick Asamoah Sakyi Key Laboratory of Mineral Resources Institute of Geology and GeophysicsChinese Academy of SciencesBeijing 100029China Department of Geology University of GhanaLegon-AccraGhana

Early Permian mafic-ultramafic complexes in eastern Xinjiang （新疆） are mainly distributed in the Beishan （北山） area, Mid-Tianshan （天山） massif and Jueluotage （觉罗塔塔） belt. Systematic compositional mapping of olivines from these Early Permian mafic-ultramafic complexes demonstrates that an apparently spatial distribution and heterogeneous partial melting in the mantle source exists from the Beishan area, across the Mid-Tianshan massif, to the Jueluotage belt from the south to the north. This is probably consistent with the spatial evolutional differences and tectonic features of these three belts. The decreasing degree of partial melting, as revealed by decreasing Fo contents of olivines, from south to north and from east to west reflects the southward subduction of the Paleo-Asian Ocean and the south location of the indistinct mantle plume in the Permian. Simultan ously, NiO and Fo-mapping in olivine also indicates that sulfide segregation before olivine crystallization played an important role in Ni-Cu mineralization in the mafic-ultramafic complexes. Olivines with the compositional range of Fo （77-86） and NiO （less than 0.22 wt.%） are more favorable for Ni-Cu sulfide mineralization.

了解并利用行星矿产资源、可持续永久开发太空成为行星科学与深空探测的一项重要研究任务。而行星矿产资源的开发利用,需要运用行星科学与地质学特别是矿床学的基础理论,利用行星观测、探测及开发技术方法,研究行星矿产资源形成演化规律,查明行星矿产资源的类型、特征、储量和分布规律;进行行星矿产资源的地质调查、岩石-矿石成分、结构与性能、元素赋存状态、开发利用条件评价与预测,为行星矿产资源开发与太空的可持续永久开发建设提供基础理论与关键技术方法。因此,行星矿产资源学是研究行星矿产资源的品种、类型与分布规律、行星矿产资源成因演化与比较行星成矿学、行星矿产资源勘查评价技术与开采利用工程学的交叉学科。笔者从行星资源地质学的视角,从地球与月球的层圈结构、演化历史、岩石组成与表生环境,研判月球可能产出的矿产资源类型。认为与月海玄武岩、月幔(柱)和陨石撞击成因的层状岩体与镁铁-超镁铁质小岩体有关的铬铁矿-铜镍钴硫化物-铂族元素-钒钛磁铁矿-金刚石矿产,KREEP岩以及月幔柱熔融上覆岩石圈所产生碱性岩相伴的铌-钽-铍-铀等稀有-稀土矿产,具有形成条件与产出可能,从而拓展可能的矿产类型、品种,从更宽广的视角研究月球矿产并规划月球基地建设资源供给。火星上由于水(以及可能存在的板块构造)的存在,除岩浆矿床之外,火星可能具备发育与化学风化沉积、次生富集作用以及变质作用有关矿产的形成条件,具有形成金属与非金属资源的禀赋,可与地球矿产相媲美。未来行星资源地质学应加强地质学、行星化学、行星地质学、行星物理学、矿业工程、冶金工程和材料学的交叉融合及理论应用,发展行星地质勘探方法与智能机器人工程技术,发展高/低温、高/低压、高辐照、低/微重力环境条件下样品采集、加工、多尺度测试分析理论与方法,培养行星资源地质资源与开发工程学科人才。

新疆北山地区的旋窝岭岩体侵位于下石炭统红柳园组变质砂岩中,辉长岩的锆石SIMSU-Pb定年结果为260.7±2.0Ma,晚于区域上其它岩体的成岩年龄。该岩体由橄榄岩、橄长岩、橄榄辉长岩和辉长岩组成,岩石较新鲜,具有典型的包橄结构和辉长结构,各岩性中均可见斜长石,而斜方辉石仅在辉长岩中出现。橄榄石的Fo值在80～85之间,NiO含量介于0.1%～0.2%之间;单斜辉石主要为普通辉石和透辉石,斜方辉石为古铜辉石。这些镁铁质矿物和斜长石成分与全岩的地球化学特征具有很好的相关性,说明该岩体母岩浆的演化过程主要受控于结晶分异作用。全岩的MgO含量在9.5%～21.8%之间,具有平坦的稀土配分型式和正Eu异常以及微量元素Nb、Zr、Hf的负异常等。因此,旋窝岭岩体可能是在北山裂谷形成过程中由于岩石圈地幔高程度部分熔融形成的高镁玄武质岩浆分异演化的产物,具有一定的铜镍硫化物矿床的成矿潜力。
