Abstract The origins of magnetite-apatite deposits are controversial, and the crux debate is what types fluids form these rocks. We present evidence from 20 worldwide showing ubiquitous involvement molten salts. studied distributed globally, various tectonic settings, Precambrian to Quaternary in age. In every case, water-poor polycrystalline melt inclusions ore-stage minerals dominated by sulfate, chloride, carbonate components plus variable proportions calc-silicates, phosphates, iron ±...
Granitic pegmatite deposits, which are usually products of orogenic processes during plate convergence, can be used to demonstrate regional tectonic evolution processes. In the eastern Tibetan Plateau in China, Jiajika, Dahongliutan, Xuebaoding, Zhawulong, and Ke’eryin rare metal deposits located southern, western, northern, midwestern, central areas Songpan–Ganzê belt, respectively. this study, we dated two muscovite Ar–Ar ages 189.4 ± 1.1 Ma 187.0 from spodumene pegmatites Dahongliutan...
The Heishishan skarn Cu-Pb-Zn deposit is located in the Wulonggou area, middle part of East Kunlun Orogenic Belt. ore body occurs at contact between monzogranite and marble Paleoproterozoic Jinshuikou Group. U-Pb analysis zircon grains shows that granodiorite were formed 241.7±1.0 Ma 243.1±0.9 Ma, respectively. Bulk-rock analyses show has similar chemistry characteristics to those adakitic rocks, being rich silicon, aluminum, potassium, sodium, poor iron magnesium, with high Mg# values...
With the explosive growth in demand for lithium (Li) resources, Mufushan area has been a hotspot Li deposit exploration China recent years. Geochemical maps and geochemical anomaly are basic of mineral resources. A fixed-value method to contour map is presented here, which concentrations divided into 19 levels on 18 fixed values, ranging from 5 μg/g (corresponding detection limit) 1858 cut-off grade hard-rock type) illustrated six color tones corresponding areas low background, high anomaly,...
Abstract The Lhasa terrane, forming one of the main tectonic components Himalayan–Tibetan orogen, has received a lot attention as it records multiple episodes plate spreading, subduction and collision within realm Paleo-Tethys Ocean. A review mineralogical, petrological, geochemical geochronological data eclogites, associated blueschists garnet-bearing mica schists from Sumdo high- ultrahigh-pressure metamorphic (HP/UHP) complex in central/southern part is present here so that origin...
The West Qinling Orogen is an important Au-W ore belt; however, the spatio-temporal and genetic relationships of W Au ores remain unclear. This study takes Zhaishang deposit, one largest deposits in Orogen, to trace their connections. geological observation reveals that high-grade are commonly characterized by extensional hydrothermal veins. In contrast, hosted breccia zones, which cut ore-controlling structures, even though overlap locally. mineral assemblages associated with...
The No. 5 pegmatite vein is the most evolved and well mineralized in Renli deposit, with beryl being important beryllium mineral. represents one of gem-quality aquamarine mines at Renli. In this study, crystals from were examined by EMPA (electron microprobe analysis), ICP-MS (inductively coupled plasma-mass spectrometry), XRD (diffraction X-rays), FTIR (fourier transform infrared spectrometer), Raman analyses. Field petrographic observations showed that are euhedral to subhedral light...
甲基卡位于松潘-甘孜造山带内,为特大型花岗伟晶岩型锂-铍矿床。前人以锂辉石中发育的富子晶包裹体为研究对象,着重剖析了甲基卡锂成矿的物理化学条件。然而,就伟晶岩熔(流)体的演化过程,特别是稀有金属成矿的富集机制和物理化学条件,仍缺乏有效制约。308号脉作为甲基卡出露最大的钠长石型锂-铍伟晶岩脉,具有良好的内部分带,较完整地记录了甲基卡伟晶岩结晶演化过程。本文以308号伟晶岩脉为研究对象,开展了系统的流体包裹体研究工作。308号脉较早阶段的结晶介质以外带绿柱石中富子晶流体包裹体为代表,为高温(492~592℃)、低盐度(0.8%~8.5% NaCleqv)、弱碱性(CO<sub>3</sub><sup>2-</sup>和HCO<sub>3</sub><sup>-</sup>)、富挥发分(F、P、B、Li)的硅酸盐水体系,估算成矿压力平均值为400MPa。308脉较晚阶段的结晶介质以内带锂辉石中富子晶流体包裹体为代表,为高温(482~565℃)、低盐度(1.6%~8.5%...
Abstract As one of the major components Himalayan–Tibetan Orogeny, Lhasa terrane plays a key role in understanding origin and evolution this giant orogenic belt opening closure Tethys oceans. The eclogite-bearing Sumdo Complex central was recognized as main suture Palaeo-Tethys Ocean between north south sub-terranes. Despite eclogite having been studied for long time, no attempts have applied to studying country rocks, causing confusion relationship adjacent schist. Petrological...
The Jiajika rare-metal deposit located in western Sichuan Province (China) is renowned as the largest lithium Asia, and No. 134 pegmatite dike under mining conditions area. On basis of a detailed characterization textures minerals pegmatite, two zones (the barren Zone I spodumene II) three subzones (Zone II was subdivided into microcrystalline, medium-fine grained coarse-grained zones) have been identified. mineralogical characteristics other indicator from each zone were evaluated by EPMA...

锂辉石(Spd)和透锂长石(Ptl)是富锂花岗伟晶岩中重要的锂铝硅酸盐矿物,查明锂辉石和透锂长石的形成条件和演化过程对进一步揭示花岗伟晶岩型锂矿床形成机制具有重要意义。锂辉石和透锂辉石通常产于伟晶岩的中间带或者核部,但两者结晶温度压力条件存在差异:透锂长石形成于高温低压条件,锂辉石在相对低温高压条件下稳定,两者随温度压力条件改变可发生相互转换。当温度降低时,透锂长石可以转换为锂辉石和石英(Qtz)集合体(SQI),而当压力升高时,锂辉石和石英集合体又可以转换为透锂长石。精确厘定锂辉石和透锂长石的相互转换温度压力条件,可以揭示富锂伟晶岩形成演化的<i>P-T</i>轨迹。本文基于近年来关于锂辉石、透锂长石等相关研究成果,总结了其产出特征和形成条件,认为:(1)在富锂伟晶岩体系内,锂铝硅酸盐矿物的结晶主要受温压条件控制,与熔体成分关系较小,锂辉石和透锂长石稳定温压范围为400~680℃、160~400MPa;(2)锂辉石在岩浆出溶流体晚期演化而成的偏碱性流体叠加作用下,先后发生钠化/钾化、白云母化和锂绿泥石化等蚀变作用;(3)温度越高、铝饱和指数(ASI)越小,H<sub>2</su...
