The studied mafic granulites are located at Xiwangshan,Xuanhua region in the north of the Trans-North China Orogen(TNCO),occurring as lens within tonalite-trondhjemite-granodiorite(TTG)gneisses in the eastern part of the Xiwangshan *** rocks contain the representative granulite-facies minerals such as garnet,clinopyroxene,orthopyroxene,plagioclase,amphibolite,rutile and quartz,and also well-developed melt pseudomorph and *** the prograde metamorphic stage(M1)cannot be retrieved due to rare preservation of pre-peak-stage mineral associations,three distinct mineral assemblages that formed in different metamorphic stages can be identified,based on petrography and mineralogy *** peak stage(M2)is characterized by Grt2+Cpx2+Amp2+Pl2+Rt+melt pseudomorphs,and a post-peak decompression stage(M3)contains a mineral assemblage of Grt3+Opx3+Cpx3+Amp3+Pl3,while a later-retrogression stage(M4)is featured by coronas of Amp4+Pl4 surrounding *** calculating metamorphic P-T conditions using THERMOCALC,stage M2 was constrained to be 13.2–14.8 kbar and 1050–1080℃,and M3 recorded P-T conditions of 5.7–7.3 kbar and 825–875℃,while M4 yielded P of^5 kbar and T of^660℃,consistent with amphibolite facies *** into account of all these petrological data,we propose that the mafic granulite experienced a high-pressure(HP)and ultra-high temperature(UHT)granulite-facies metamorphism during the peak metamorphism,which was accompanied with a clockwise P-T path.U-Pb dating of metamorphic zircons in the granulites yields two groups of ages at 1853±14 and 1744±44 Ma,*** suggest that the older age corresponded to the HP-UHT metamorphism,while the younger age represented an retrograde metamorphic event during cooling.

钴作为当今社会必需的一种关键矿产资源,岩浆铜镍矿床是我国钴资源供应的重要矿床种类之一,该类矿床中钴元素通常赋存于镁铁质硅酸盐矿物、硫化物、类硫化物和铁氧化物中,然而镁铁质硅酸盐和铁氧化物中的钴难以分选利用,因此钴赋存状态的厘定是铜镍矿床中钴资源评价和利用的重要前提。新疆东天山-北山地区发育大量晚古生代、普遍伴生钴的岩浆铜镍矿床,其中位于北山地区的坡一镍矿床以赋含高镍硫化物为特色,是研究岩浆铜镍矿床中钴元素的赋存状态、分布特征以及钴与镍相互关系的理想对象。坡一镍矿的含矿岩相主要为单辉橄榄岩、纯橄岩和橄长岩,以稀疏浸染状矿化为主,钴主要以类质同象形式赋存于镍黄铁矿,其次为铬尖晶石、橄榄石和磁黄铁矿,少见独立钴矿物。矿物微区原位分析结果显示原生矿物中钴含量由高到低依次为镍黄铁矿(~8404×10^(-6))>>铬尖晶石(~475×10^(-6))>磁黄铁矿(高Ni含量)(~299×10^(-6))>橄榄石(~137×10^(-6))>黄铜矿(~13.0×10^(-6))>磁黄铁矿(低Ni含量)(~8.35×10^(-6))。坡一岩体的蚀变橄榄岩中发育三种产状的次生磁铁矿:蚀变橄榄石裂理中细脉状磁铁矿、铬尖晶石边部环状磁铁矿边、硫化物矿边部和裂隙中次生磁铁矿边。元素面扫描结果显示次生磁铁矿中Co含量明显高于原生硫化物、氧化物和硅酸盐矿物,且显示富Co贫Ni特征。坡一矿床中硫化物和硅酸盐矿物表现出明显的Co-Ni正相关,而铬尖晶石中Co和Ni显示负相关,表明Co^(2+)主要以类质同象形式替代Fe^(2+)进入硫化物和硅酸盐矿物晶格,以替代Fe^(2+)、Ni^(2+)的形式进入铬尖晶石。坡一矿床中Ni和Co的共生行为,主要归因于岩浆演化过程硫化物熔离和硅酸盐矿物分离结晶过程中相近的配分行为,而Ni和Co的离散特征主要受控于铬尖晶石的分离结晶和R值(岩浆和硫化物质量比)的变化、热液蚀变过程中次生磁铁矿Co富集作用。由于铬尖晶石与硅酸盐矿物中的钴难以分选利用,北山地区的钴矿资源勘查应关注贫铬尖晶石、橄榄石镍亏损的富硫化物超镁铁质岩体。

中亚造山带南缘东天山地区是我国战略资源Ni的重要产区,图拉尔根矿床是该地区众多铜镍矿床中以岩体高矿化比例为特色的矿床。图拉尔根杂岩体由晚石炭世基性岩体(辉长岩、角闪辉长岩)和早二叠世超基性岩体(二辉橄榄岩、角闪橄榄岩)组成,矿体呈透镜状、“悬浮”状产出于超镁铁岩体的中部和中上部,矿化类型为块状/半块状、海绵陨铁状、稠密/稀疏浸染状、星点状、斑杂状以及少量珠滴状矿化。不同类型矿石∑PGE变化较大(10.8×10^(-9)~208×10^(-9)),除块状矿石样品外,其他类型矿石(S<15%)S与PGE、IPGE与PGE元素之间均显示良好正相关,表明PGE含量变化主要受控于R因子(100~5000)变化;块状矿石的上述元素间呈现离散现象,亦反映单硫化物固溶体分异的影响。母岩浆中Pt和Pd的显著亏损以及矿石中Cu和Pd的强烈解耦,表明图拉尔根母岩浆经历了深部硫化物的熔离。Pd/Ir比值揭示的高镁玄武质岩浆性质和含水地幔源区可能的低程度部分熔融,表明源区硫化物残留也可能造成PGE的亏损。图拉尔根矿床的^(187)Os/^(188)Os比值和γ_(Os)值显著高于造山带橄榄岩地幔和全球典型岩浆铜镍矿床,反映其成矿母岩浆受到地壳物质强烈混染;Os-Nd同位素端元混合模拟显示有限的硅铝质地壳混染难以解释高^(187)Os/^(188)Os比值,图拉尔根矿床的Os同位素信息主要受到地壳硫化物改造,因此外源硫加入是图拉尔根铜镍成矿的关键因素之一。

汇聚板块边缘的俯冲带是壳幔相互作用最为强烈的区域,其重要特征是俯冲板片将地表物质带入地球内部并在上覆板块产生强烈的岩浆活动,同时孕育铜、钼、金和其他具有重要经济价值的金属矿床。现有研究显示,俯冲带弧岩浆的氧逸度总体高于洋中脊玄武岩,但对于弧岩浆的高氧逸度的成因存在争议。目前有关弧岩浆高氧逸度的来源存在如下认识:(1)板片俯冲过程中释放的高氧化性流体对地幔楔持续氧化,该流体可能来源于蚀变基性洋壳、上覆沉积物和/或下伏的蛇纹岩化地幔;(2)地幔部分熔融形成的含水熔体与周围地幔反应过程中,还原组分(例如H_(2))的丢失促使氧化性弧岩浆的形成;(3)上升熔体在深部岩浆房演化过程中,富Fe^(2+)矿物相(石榴子石、角闪石等)的分离结晶和/或去气作用致使残余熔体氧逸度升高。本文系统梳理了弧岩浆高氧逸度成因的最新进展,从俯冲带不同来源流体(俯冲沉积物、基性洋壳、岩石圈地幔)的氧化性、地幔尺度内熔岩反应、地壳尺度内弧岩浆分离结晶和去气作用三方面进行系统总结,评述研究现状和争议存在的原因,并对未来研究进行了展望。

In this paper, we suggest one compound chaos image encryption method with time- varying multilevel initial parameters. This algorithm combines Subsection-linearity mapping, Chebyshev mapping with Logistic mapping in order to disturbing values of each image point and the array of original images based on chaotic second-scrambling way. The chaotic system uses time-varying system clock to change the first chaotic mapping initial parameter, and takes those chaotic sequences which generated by the first chaotic mapping as the initial parameters for the second chaotic mapping, then generate two-dimensional image pixel position scrambling matrix, and uses the same system clock to lock Chebyshev mapping initial parameter, then generate two-dimensional image pixel value transforming matrix. By this way for using the time-varying system clock, The encryption system can randomly changes many initial parameters of chaotic image encryption system to enhance image transmission security, has the capability of “one time one secret”. The simulation results show that this algorithm is simple, safe, easy to achieve with software and has huge secret key space.
