Metallogenic Series Related to Permian Mafic Complex in North Xinjiang:Post-collisional Stage or Mantle Plume Result?

引用

Acta Geologica Sinica(English Edition) 2008年第4期82卷 788-795页

作者： WANG Yuwang WANG Jingbin WANG Lijuan long lingli School of the Earth Sciences and Resources China University ofGeosciences Beijing 100083 China Beijing Institute of Geology for Mineral Resources Beijing 100012 China

There are four deposit types related to a Permian mafic complex in northern Xinjiang, i.e., copper-nickel sulfide deposit, vanadic titanomagnetite deposit, magnetite （-cobalt） deposit and Cu-Ni- VTiFe composite deposit. The deposits are distributed spanning tectonic units with close and consecutive metallogenic ages. A transitional deposit type can occur among the end-member deposits. Trace elements of host rocks show that they can derive from similar source area. Hence, they constitute a particular metallogenic series related to a mafic-ultramafic complex that is also a symbol series of the post-collisional stage of the Central Asia Metallogenic Province （CAMP）. The metallogenic ages of the series are between 260 Ma and 300 Ma throughout the Permian. Unlike mineralization from a mantle plume, the metallogenic period of this series spans at least 40 Ma. Compared with related deposits of the Emeishan mantle plume, the North Xinjiang series has a similar ore-forming element assemblage but has preferably developed Cu-Ni sulfide deposits rather than vanadic titanomagnetite deposits. In concomitance with this series, North Xinjiang area has developed a set of syntectonic Au-Cu-Mo metallogenic series related to a felsic volcanic-intrusive complex, which might indicate that there is no direct relationship with mantle plume activity. From early to late, i.e., the sequence of copper-nickel sulfide to magnetite （-cobalt） to vanadic titanomagnetite deposit, the host rock series evolves from mafic-ultramafic and tholeiite series to mafic and alkalic series, the ~REE content tends to increase with increasing of REE fractionation, and some of the trace elements （particularly LIL） also show an increasing tendency. The above evolutionary regularity possibly reflects a course where the magma source deepens and thermal interface moves down, energy gradually exhausts, and neo-continental crust forming in the postcollision stage tends to stabilize.

Physicochemical Control of the Early Permian Xiangshan Fe-Ti Oxide Deposit in Eastern Tianshan(Xinjiang),NW China

引用

Journal of Earth Science 2018年第3期29卷 520-536页

作者： Yu Shi Yuwang Wang Jingbin Wang Lutong Zhao Hongjing Xie lingli long Tao Zou Dedong Li Guochao Zhou Beijing Institute of Geology for Mineral Resources Beoing 100012China School of Earth Sciences and Resources China University of GeosciencesBeijing 100083China Faculty of Land Resource Engineering Kunming University of Science and TechnologyKunming 650093China

The Xiangshan mafic-ultramafic complex is one of the major Early Permian maficultramafic intrusions in eastern Tianshan （Xinjiang, NW China）, and consists of two major intrusive phases. The first intrusive phase is mainly gabbroic rocks hosting ilmenite mineralization, while the second intrusive phase is mainly lherzoilite associated with Ni-Cu sulfide mineralization. The Xiangshan ilmenite orebodies hosted in the Fe-Ti oxide-bearing gabbro occur along the contact between hornblende gabbros and leucogabbros. The hornblende gabbros and Fe-Ti oxide rich gabbros at Xiangshan are newly dated to be Early Permian （280.1 and 279.2 Ma, respectively）. Major and trace element compositions of zircons and whole rocks from Xiangshan hornblende gabbro and Fe-Ti oxide gabbro have been measured by in situ excimer laser ablation ICP-MS. Zircon Ce^4＋/Ce^3＋ ratios based on lattice-strain model and Ti-in-zircon temperatures of hornblende gabbro and Fe-Ti oxide gabbro of the Xiangshan complex are calculated to evaluate the physicochemical variations during the ilmenite mineralization. Whole-rock geochemistry and zircon trace element geochemistry suggest that Fe-Ti oxide gabbros were formed from a basaltic parent magma which had undergone a transfromation from being H2O-rich to H2O-poor. During the magmatic evolution, primitive, HEO-poor basaltic melts may have been replenished into the system, increasing its solidus temperature and decreasing its oxygen fugacity and H2O contents. This may have supperessed the Ti-rich poikilitic hornblende fractionation and promoted the plagioclase fractionation, which consequently concentrated the ore-forming components in the residual melts and generated the ilmenite mineralization.

The Tuerkubantao ophiolite melange in Xinjiang,NW China:New evidence for the Erqis suture zone

引用

Geoscience Frontiers 2012年第5期3卷 587-602页

作者： Yuwang Wang Jingbin Wang Lijuan Wang lingli long Pingzhi Tang Zhen Liao Huiqiong Zhang Yu Shi Beijing Institute of Geology for Mineral Resources Beijing 100012China KeyLaboratoryofMineralResources InstituteofGeoiog and Geophysics CASBeijing 100029China SinoTechMetalsExplorationCo. Ltd.Beijing100012China ChinaUniversityofGeosciences(Beijing) Beijing100083China

The extension of the suture zone between the Siberian and Kazakhstan continents in China has been a matter of debate because few outcrops of ophiolitic melange have been found so far. The recently found Tuerkubantao ophiolitic melange, which is located east of the Kekesentao Mt. in the Buer- jin County of the Chinese Altay, provides an important clue for this problem. This paper presents the results of field investigation, petrology, U-Pb isotope dating of zircons and bulk-rock geochemistry of the Tuerkubantao melange rocks. The melange consists of fault-contacted ultramafic rocks, gabbro, diabase, basalt, flysch and granitoids. The ultramafic-mafic rocks are Mg-rich （Mg#= 4.25-6.35） and w（SiO2） spans 38.8%--46.8%. Basalt and gabbro are geochemically similar and are characterized by low w（FeOt）（10.9%）, total alkali w（Na20 ＋ K20） = 2.58%） and w（TiO2）（1.17%） and affinity to the Mg-rich tholeiite series. The flat REE and trace-element patterns of the ultramafic-mafic rocks are indic- ative of their ophiolite origin, i.e., formation in a mid-oceanic ridge setting. The fragments of low-K gneissic granite formed in suprasubduction or syn-collisional setting. Zircons from gabbro and gneissic granite yielded U-Pb ages of 363 and 355 Ma, respectively, suggesting Late Devonian mid-oceanic spreading and oceanic subduction accompanied by suprasubduction magmatism. The Tuerkubantao ophiolite together with the Qiaoxiahala and Buergen ophiolites of the Kekesentao belt define an ophiolitic melange belt extending along the Erqis fault. This belt probably belongs to the Ural- Zaisan-South Mongolian suture-shear zone formed during the subduction of the Paleo-Asian Ocean and subsequent collision of the Siberian and Kazakhstan continents.

Petrogenesis and Metallogenesis of the Niumaoquan Gabbroic Intrusion Associated with Fe-Ti Oxide Ores in the Eastern Tianshan, NW China

引用

Acta Geologica Sinica(English Edition) 2018年第5期92卷 1862-1878页

作者： SHI Yu WANG Yuwang WANG Jingbin XIE Hongjing MAO Qigui ZHAO Lutong long lingli LI Dedong ZHOU Guochao Beijing Institute of Geology for Mineral Resources Beijing 100012 China School of Earth Sciences and Resources China University of Geosciences Beijing 100083 China

The Niumaoquan layered gabbroic intrusion is in the southern margin of the Central Asian Orogenic Belt in North Xinjiang, China, and hosts a Fe-Ti oxide deposit in its evolved gabbroic phases. In this paper, we report zircon U-Pb age, Sr-Nd-Hf isotopes, plagioclase chemistry, and whole-rock geochemistry of the Niumaoquan layered gabbroic intrusion. Zircon grains separated from an anorthosite sample analyzed by laser ablation inductively coupled plasma mass spectrometry yielded a concordia age of 314.7±0.74 Ma, indicating that the Niumaoquan ore-bearing gabbroic intrusion was emplaced during the Late Carboniferous. The olivine gabbro texture and plagioclase chemistry suggest that plagioclase was an early crystallized silicate phase that crystallized prior to olivine. Fractional crystallization and accumulation of plagioclase significantly controlled the evolution of the Niumaoquan gabbroic intrusion and contributed to the formation of anorthosite layers, causing metallogenic elements to become enriched in the residual melt. The Niumaoquan gabbroic intrusion is characterized by the enrichment of large ion lithophile elements and depletion of high field strength elements, positive zircon εHf（t） values（＋2.1 to ＋12.2）, positive εNd（t） values（＋3.3 to ＋5.2）, and low initial ^（87）Sr/^（86）Sr ratios（0.7039 to 0.7047）, suggesting that the parental magma was produced by interactions between metasomatized lithospheric mantle and depleted asthenospheric melts at an early post-collision stage. The Fe-Ti oxide mineralization of the Niumaoquan intrusion benefited from interactions between depleted asthenospheric melts and lithospheric mantle, and fractional crystallization of abundant plagioclase and magnesian minerals.

The Heiyingshan granite and the Laohutai granite plutons exposed in the Southwest Tianshan resemble A-type granites geochemically. Analysis shows that the both are ferron calc-alkalic peraluminous or ferron alkali-calcic peraluminous with a relatively high concentration of SiO2 （〉70%）, high alkali contents （Na20 ＋ K20 = 7.14%-8.56%; K20〉N20; A/CNK = 0.99-1.20）, and pronounced negative anomales in Eu, Ba, St, P and Ti. A SHRIMP zircon U-Pb age of 285±4 Ma was obtained for the Heiyingshan hornblende biotite granite intrusion. The geochemical and age dating data reported in this paper indicate that these granites were formed during the post-collisional crustal extension of the Southwest Tianshan orogenic belt, in agreement with the published data for the granites in the South Tianshan.

Problems of PGE metallogenesis related to mafic-ultramafic complexes in North Xinjiang,China

引用

Geoscience Frontiers 2011年第2期2卷 187-198页

作者： Yuwang Wang Jingbin Wang Lijuan Wang lingli long Zhen Liao Huiqiong Zhang Pingzhi Tang Beijing Institute of Geology for Mineral Resources Beijing 100012 China Key Laboratory of Mineral Resources Institute of Geology and Geophysics Chinese Academy of Sciences Beijing 100029 China

Platinum group element （PGE） mineralization is mostly related to mafc--ultramafic complexes of the dominant magmatic deposit type. Mineralization of this type mainly relies on two conditions： the abundance of PGE in magma, and the presence of mechanisms favorable to PGE enrich- ment and separation from sulfur-saturated magma during magmatic evolution. Mafic-ultramafic complexes are widely developed in North Xinjiang, including （1） the large-scale copper-nickel deposits of Kelatongke, Huangshan, Huangshan East, and Tulargen, （2） numerous small to medium-sized copper- nickel deposits such as Xiangshan, Tudun, Hulu, Baishiquan, and （3） the Xiangshan West and Weiya medium-sized V--Ti magnetite deposits. However, mafic-ultramafic complexes in North Xinjiang rarely form PGE deposits. Therefore, questions about PGE metallogenesis in North Xinjiang are discussed in this paper from the standpoint of the ore-forming mechanism of PGE deposits and the characteristics of the North Xinjiang magma sources. The rock types of the post-collisional mafic--ultramafic complexes in North Xinjiang are of a ferrous rock series formed by fractional crystallization, a rock type generally favorable for hosting PGE. For the Cu-Ni sulfde deposits of North Xingjiang, the assimilation of crustal material causes sulfide liquation during processes of magmatic evolution and mineralization. This can be shown petrogeochemically, including the characteristics of Sr, Nd, Pb, O, Os, and S isotopes, which indi- cate a magmatic ore-forming mechanism for the Xingjiang PGE deposits. The principal reason for weak PGE mineralization in North Xinjiang may be ascribed to a widely-developed depleted mantle source （with positive end values） that underlies it. The North Xinjiang lithosphere is not of typical Precambrian cratonal type, but has more affinities with modified oceanic lithosphere or immature continental lithosphere that would constitute PGE-poor original magma sources unfavorable to PGE mineralization.
