Abstract: 普朗铜矿床是格咱岛弧产出的超大型斑岩型铜矿床,以往较多关注于含矿的石英二长斑岩,而对矿区出露的闪长岩、花岗闪长斑岩研究相对薄弱.对普朗矿区的闪长岩和花岗闪长斑岩开展了地球化学和锆石年代学分析,结果显示,闪长岩SiO2 含量为61.02%~61.23%,K2 O含量为5.40%~6.13%,MgO含量为3.50%~3.61%,(Na2O+K2 O) 总碱含量为7.79%~8.47%,K2 O/Na2 O>2,属中性超钾质碱性岩;花岗闪长斑岩SiO2 含量为65.50%~66.14%,K2O含量为4.03%~4.14%,MgO含量为2.01%~2.15%,(Na2 O+K2 O) 总碱含量为7.54%~7.72%,K2 O/Na2 O>1,属酸性钾质碱性岩.花岗闪长斑岩与中甸地区火山岩具有一致的Sr-Nd同位素特征,而闪长岩εNd ( t )值变化范围大,二阶段模式年龄分散(369 Ma、913 Ma、1 138 Ma),指示有富集组分的混入.闪长岩LAICPMS锆石U-Pb年龄为227.0±2.9 Ma;花岗闪长斑岩LAICPMS锆石U-Pb年龄为211.5±3.7 Ma.结合岩石主量、微量元素、全岩SrNd同位素及锆石U-Pb年龄,提出甘孜-理塘洋在长时期的西向俯冲(约25 Ma)过程中,普朗矿区(局部)可能发生过由挤压向伸展构造体制的转换,激发幔源的岩浆活动,导致钾质碱性小岩体侵位,该过程对该超大型斑岩铜多金属矿的形成具有重要意义.
The Pulang copper deposit is a super-large porphyry deposit located in Geza island arc in Yunnan Province.Previous studies were mostly concentrated on the ore-bearing quartz-monzonite porphyry,while the research on the diorite and granodiorite porphyry was relatively weak.In this paper,we present geochemistry and zircon chronology analysis on the diorite and granodiorite porphyry in Pulang mine,northwest of Yunnan Province.The diorite is characterized by low SiO2 (61.02%- 61.23% ), high K2O (5.40%-6.13%) and total alkali(K2 O+Na2 O=7.79%-8.47%),K2 O (5.40%-6.13%),MgO ( 3.50%- 3.61%),and K2O/Na2O is bigger than 2.Likewise,the granodioriteporphyry is characterized by medium SiO2 ( 65.50%- 66.14%) and high total alkali (7.54%-7.72%),with MgO (2.01%- 2.15%),and the K2O/Na2O is bigger than 1.They are enriched in large-ion lithophile and light earth elements,but depleted in high fieldstrength and heavy rare earth elements,and with weak to negative Eu anomalies.Furthermore,diorite yields lower (87Sr/ 86Sr)i ratios ( 0.705 24- 0.705 31) than granodiorite-porphyry ((87Sr/ 86Sr) i 0.705 58-0.705 62), and the granodiorite-porphyry yields negative εNd( t )values from -3.34 to -1.01,while the diorite yields variable εNd( t )values from -1.65 to 7.78.New U-Pb dating of zircons of diorite and granodiorite-porphyry are 227.0±2.9 Ma and 211.5±3.7 Ma respectively.Comprehensively,we propose that a transformation from compression to extension process may have occurred in the Pulang area during the long period of westward subduction of Garze-litang ocean (about 25 Ma),which has triggered the mantle source magmatic activity,and has resulted in the emplacement of deep source (ultra)potassium alkaline.And the transformation process is crucial to the formation of super-large porphyry deposit

Abstract: The Pulang complex in Yunnan Province is divided into three stages of intrusions based on their contacting relationship and petrological characteristics. The lithologies of the intrusions include quartz dioritic porphyry formed in the first stage, quartz monzonitic porphyry in the second stage, and granodioritic porphyry in the third stage. The crystallization ages of the intrusions were determined by using the single-grain zircon U-Pb method. The single-grain zircon U-Pb isotopic ages are defined as 221.0±1.0Ma, 211.8±0.5Ma and 206.3±0.7Ma for the first, second and third stages of intrusions, respectively. These data combined with the results of petrochemical and Sr isotopic analyses support the formation of the Pulang complex in the Indo-Chinese epoch by multi-stages of gushing emplacement of the magmas derived from mixing source of mantle with crust.

Abstract: 云开地块中生代构造演化是华南地区的研究热点之一.通过对云开地块变质基底中的混合岩、片麻岩(5个样品)和花岗岩(1个样品)开展锆石LA-ICP-MS U-Pb定年,获得440.3±3.3 Ma、230.2±2.9 Ma、230.7±1.3 Ma、459.5±2.7 Ma、431.5± 4.3 Ma、229.2±5.4 Ma、229.7±2.7 Ma 7组变质(深熔)或岩浆年龄和2组(样品1432-1和ID7-3)碎屑锆石年龄,碎屑锆石年龄范围均为太古代-新元古代,且具有~1.0 Ga年龄主峰,与天堂山岩群和云开群碎屑锆石年龄谱相似.区域资料表明云开地块天堂山岩群和云开群具有相似的物质组成,均形成于早古生代-新元古代,存在变质程度和物质面貌的差异;在加里东期构造-热事件的基础上,广泛叠加了印支期区域变质(深熔)-构造-流体作用影响.4个样品中(1431-1、1432-1、D116-3和ID7-3)锆石原位Lu-Hf同位素组成显示,加里东期变质和深熔锆石Lu/Hf同位素组成基本一致,应继承了原岩的同位素组成特征.印支期变质和深熔锆石Lu/Hf同位素组成不同,可能主要由变质作用和深熔作用的差异所致.以古-中元古代为主的地壳物质参与了加里东期和印支期变质-深熔作用,在加里东期和印支期深熔作用过程中,均有少量幔源物质的加入,印支期幔源物质的贡献相对显著.
The Mesozoic tectonic evolution in Yunkai massif have always been one of hot topics in South China. Zircons from five metamorphic rocks including migmatite and gneiss and one granite from the metamorphic basement in Yunkai massif were measured by the LA-ICP-MS U-Pb dating method, yielding 7 metamorphic (anatectic) or granitic ages (440.3±3.3 Ma、 230.2±2.9 Ma 、230.7±1.3 Ma、459.5±2.7 Ma、431.5±4.3 Ma、229.2±5.4 Ma、229.7±2.7 Ma) and 2 groups of detrital ages. Both the detrital zircons showed Archaean-Neoproterozoic age range with ~1.0Ga age peaks, which were similar with those of the Tiantangshan Group complex and the Yunkai Group. Together with the regional data, it was concluded that the Tiantangshan Group complex and the Yunkai Group, which were analogous in provenance and formed in Early Palaeozoic-Neoproterozoic, were broadly overprinted by the Indosinian metamorphism (anatexis)-deformation-fluid activity after the Caledonian tectonicthermal events,resulting in differences in metamorphic grade and appearance. In situ zircon Lu-Hf isotopic analysis from four samples showed that both the isotopic compositions of Caledonian metamorphic and anatectic zircons were similar with each other, which was ascribe to inheriting the compositions of provenance rocks, whereas the different isotopic compositions of Indosinian metamorphic and anatectic zircons could be caused by individual mechanism of metamorphic and anatectic processe. It was inferred that the dominant Paleo-Mesoproterozoic crustal material played important role in the metamorphism and anatexis processe in Caledonian and Indosinian, and a few mantle-derived material was added in the anatectic processe in Caledonian and Indosinian with relatively remarkable contribution of mantle-derived material in Indosinian

Abstract: Geophysical study based on parts large, super large and polymetallic deposits discover, substance and energy intense exchanges in depths of Earth under the affect of heat power. When hydrothernal (magma) upwelling along channel (shatter belt, weak formation or faults), the mineral elements are congregated in deep suitable position of rock stratum. It is necessary that there are formed large and relatively large in acidity,intermediate acidity and basic-ultrabasic magmatic rock mass at the same time. There these types magmatic rock are carried thermal energy and actuated the deep matter divergence,regulate again replacement, alteration and metamorphism with effect of wall rocks. In this deep process and under environment of medium and structure, mineral elements are congregated nearby the large or relatively large magmatic rock mass and coupling. Thus there are formated large, superlarge and polymetallic deposits.

Superlarge ore deposits and development of China’s mineral resources
Zhenhua Zhao
Chinese Science Bulletin , 1999, DOI: 10.1007/BF02886000
Abstract: The ever increasing demand of mineral resources in China was assessed and it is suggested that the development of superlarge ore deposits was the best way to meet such demand. Research and exploitation of superlarge ore deposits can bring great economic and social benefits to the society. It is also the best way to a better integration of resource industry development and environmental protection and therefore provides a basis of sustainable development of China. China has made important advancements in the research of superlarge ore deposits and especially in classification, selectivity and confinement of deposit types and temporal and spatial distributions. It is suggested that the metallodynamics and the interaction between the crust and the mantle and the core should be studied. At the same time, a new concept of resources should be established in order to build a new integrated system for research, and resource development and environmental protection.

Abstract: The Miaoershan-Yuechengling complex pluton is the largest granitoid complex in the western Nanling metallogenic belt with a surface exposure of >3000 km2. The complex pluton is composed of an early stage granitoid batholith and late stage small intrusions. The early stage batholith contains mainly medium-grained porphyritic mica granite and porphyritic monzonite granite, whereas the late stage intrusions are composed of muscovite granite porphyry and muscovite monzonitic granite. There are many W-Sn-Mo-Pb-Zn-Cu ores in the contact zone between the batholith and strata, forming an ore-rich belt around the batholith. Based on zircon LA-ICP-MS U-Pb ages, the southwestern part of the early stage batholith formed at 228.7 ± 4.1 Ma (MSWD = 2.49), with slightly earlier magmatic activity at 243.0 ± 5.8 Ma (MSWD = 2.62). The Yuntoujie muscovite granite was associated with W-Mo mineralization and has a zircon LA-ICP-MS U-Pb age of 216.8 ± 4.9 Ma (MSWD = 1.44). The Re-Os isochron age of molybdenite from the Yuntoujie W-Mo ore was 216.8 ± 7.5 Ma (MSWD = 11.3). Our new isotope data suggest that the late stage intrusive stocks from the southwestern Miaoershan-Yuechengling batholith were closely associated with W-Mo mineralization from the Indosinian period. These new results together with previous isotope data, suggest that South China underwent not only the well-known Yanshanian mineralization event, but also a widespread Indosinian metallogenic event during the Mesozoic period. Therefore, South China has a greater potential for Indosinian mineralization than previously thought such that more attention should be given to the Indosinian ore prospecting in South China.
