| 1 | 开鲁盆地砂岩型铀矿中黄铁矿与铀矿化成因关系探讨显示文摘开鲁盆地位于松辽盆地西南部,是中国北方砂岩型铀矿勘查的重点地区,自钱家店铀矿床发现以来,盆地内上白垩统姚家组目的层中相继发现了一些具有工业价值的铀矿床。为查明该层位中黄铁矿成因及其形成机制,探讨其与铀矿化之间的关系,本研究对含矿层砂岩中黄铁矿与铀矿物矿物学特征、黄铁矿S同位素开展细致研究。研究表明:(1)开鲁盆地姚家组砂岩中铀主要以独立铀矿物及吸附铀形式存在,独立铀矿物以沥青铀矿为主,含少量的钛铀矿及部分铀石,多数沿黄铁矿周边生长。吸附态的铀与黏土矿物密切相关。(2)姚家组砂岩中黄铁矿主要以草莓状、胶状及粒状产出,多与沥青铀矿共生,其中黄铁矿S同位素(d^(34)S=–55.6‰~23.2‰),平均值–20.87‰,变化范围很大,说明硫的分馏程度较高,硫的来源范围较广。(3)分析表明黄铁矿具有细菌硫酸盐还原作用及热化学硫酸盐还原作用两种成因,并探讨了这2种成因黄铁矿的形成机制。综合前人研究,结合研究区成矿地质背景,认为黄铁矿为铀成矿作用提供了发生还原反应所需要的还原剂,且黄铁矿及铀矿物的形成与区内热流体存在紧密联系。 | 陈梦雅 聂逢君 Mostafa FAYEK | 2021 | 地球学报2021，42，6： | 12 |
| 2 | 西准白杨河铍矿床萤石及流体包裹体特征显示文摘利用激光测温学和激光拉曼光谱方法,通过镜下观察,研究了白杨河铍矿床与铍成矿作用有关的脉石矿物(萤石),将萤石分为4 个期次,其中第三期萤石与铍成矿关系最密切.萤石流体包裹体具低盐(0.7%-7.0%)、低温(89.7℃-188.9℃)的特征,第三期萤石脉流体包裹体成矿温度99.4℃-120.5℃,成矿盐度3.5%-5.4%,与铍矿物属同-期,揭示出该矿床成矿流体为低温、低盐度热液. | 杨文龙 Mostafa Fayek 李彦龙 王谋 周剑 | 2014 | 新疆地质2014，32，1： | 11 |
| 3 | 蒙其古尔铀矿床砂岩型铀矿生物成矿作用探讨显示文摘蒙其古尔铀矿床是伊犁盆地南缘铀资源量最大的砂岩型铀矿床,关于该矿床的成因机理,也一直是铀矿地质学界关注的焦点。通过对该矿床含矿地层的地球化学特征、黏土矿物特征进行分析研究,以及对黄铁矿硫同位素的分析测试,认为在铀成矿过程中有还原物质的参与,而且该还原物质与生物作用有一定关系。生物作用参与成矿可能是蒙其古尔铀矿床矿体品位较高的重要原因。 | 刘俊平 邱余波 周剑 文战久 Fayek M 张虎军 | 2015 | 科学技术与工程2015，35，26： | 6 |
| 4 | Multistage mineralization in the Haoyaoerhudong gold deposit, Central Asian Orogenic Belt: Constraints from the sedimentary-diagenetic and hydrothermal sulfides and gold显示文摘The Central Asian Orogenic Belt,as one of world-class gold economic belts,preserves a number of giant,large black shale-hosted gold deposits,while it is still debated for origin of sulfides and gold mainly due to lack of identification for multiple stages of sulfides.The Haoyaoerhudong gold deposit is hosted in a sequence of Mesoproterozoic carbonaceous and pyritic slate,phyllite,and schist that form a tight syncline along the north margin of the North China Craton.Detailed petrography of the host rocks and mineralization have defined five stages of pyrites.The earliest form of pyrite(Py_(1))occurs as fine-grained dispersed pyrite in black carbonaceous slate and medium-to coarse-grained disseminated pyrite in pyrite-rich layers,contains relative low gold and high arsenic content,indicating a syn-sedimentary or diagenetic in origin.Stage Ⅱ pyrite(Py_(2))occurs with garnet and quartz inclusions and Py_(3) occurs as pyrite veins,contains higher gold and lower As content,and are interpreted to have formed from the dissolution-reprecipitation of Py_(1) during the peak metamorphism or post-peak metamorphism.Stage Ⅳ pyrite(Py_(4))from the pyrite-quartz veins crosscut the metamorphic garnet,contains the highest gold concentrations and other trace elements,and is considered to have formed post-peak metamorphism.Abundant native gold,electrum,and maldonite occur as inclusions within Py_(4) and monazite and in fractures that crosscut garnet.While,Py_(5) with typical remobilized feature is thought to be a product of melting of former pyrites(Py_(1) to Py_(4))triggered by the large-scale Hercynian magmatism.The sedimentary/diagenetic Py_(1) have δ^(34)S values that range from +12.4‰to +16.2‰.Later generations of sulfides,including Py_(2) to Py_(5),and Ccp_(2) to Ccp_(3),have δ^(34)S values from +9.5‰to +12.7‰.Monazite with maldonite inclusions from quartz-pyrite veins yielded an intercept age of 341.3±6.6 Ma,while coarse grained monazite associated biotite along fractures in the reefs yielded an intercept age of 254.6±8.2 Ma.The paragenetic,textural,chemical,and isotopic data suggest three distinct gold producing episodes at Haoyaoerhudong gold deposit.Gold and arsenic were clearly initially concentrated in organic muds,and enriched along the structures of diagenetic arsenic-rich pyrite.Subsequently,accompanying metamorphism and deformation,gold was liberated from the dissolution of diagenetic pyrites to form the pyrite veins.Finally,accompanying transformation of pyrite into pyrrhotite,gold was released into the metamorphic fluids to become concentrated as native gold,electrum,and maldonite in pyrite-quart veins.Monazite with age of 341 Ma from quartz-pyrite veins suggests that the third major gold mineralizing event in Haoyaoerhudong occurred before the Hercynian magmatism,suggesting that the Haoyaoerhudong deposit is a typical orogenic gold deposit rather than intrusion-related deposit. | Hai-Dong Zhang Jian-Chao Liu Mostafa Fayek | 2021 | Geoscience Frontiers2021，12，2： | 2 |
