    摘要

  • 光明萤石矿产出于湘东锡田岩体北部，为探究矿区内黑云母花岗岩与萤石成矿的关联，对岩体和萤石矿体进行了系统的地球化学研究，并利用LA-（MC）-ICP-MS对黑云母花岗岩中锆石开展了U-Pb年代学、微量元素及Hf同位素地球化学研究。结果显示，黑云母花岗岩具有高硅（SiO2=72.62%~77.34%）、高碱（Na2O+K2O=6.03%~8.66%）、富铝（Al2O3=12.02%~13.83%）特征，A/CNK值介于1.07~1.14之间，为过铝质花岗岩。3个样品低U锆石的206Pb/238U年龄加权平均值在215~218 Ma之间，指示花岗岩侵位于印支期。矿区黑云母花岗岩印支期—燕山期锆石年龄为237~133 Ma，在230~210 Ma、190~170 Ma、150~130 Ma存在3个较集中的年龄峰期，暗示岩浆侵位后受到热事件影响，推测矿区岩浆活动具有多阶段性。黑云母花岗岩岩体有较强的负Eu异常，且富集大离子亲石元素Rb、Th、U，亏损Ba、Nb等元素；萤石具有中等程度的负Eu异常，Rb、Ba、Nb、Hf相对亏损，U、La、Nd、Zr、Y相对富集。按照燕山期成矿岩浆活动时间（133 Ma）估算，岩体εNd（t）=-11.2~-10.6，二阶段模式年龄为1793~1837 Ma；萤石εNd（t）=-11.3~-10.0，二阶段模式年龄为1741~1848 Ma，二者具有较一致的Nd同位素组成。岩体锆石Hf同位素测定值具有较大的变化范围，176Hf/177Hf=0.282234~0.282420，εHf（t）=-16.7~-8.5，TDM2=1756~2214 Ma，显示古—中元古代地壳模式年龄。综合研究发现，光明萤石矿多阶段岩浆活动起源于成熟地壳白云母的脱水熔融，经历了印支期—燕山期多期次的岩浆补给和较强的结晶分异。萤石矿石与矿区内燕山期花岗岩具有相似的稀土与微量元素特征，与黑云母花岗岩不同，暗示光明矿床萤石成矿与区内燕山期岩浆活动有关，成矿流体主要为岩浆热液，并有少量大气降水加入。

    Guangming fluorite deposit is located in the north of Xitian granite pluton in the eastern Hunan.Aiming to investigate the correlationship between the biotite granite and fluorite mineralization in the mining district, systematic geochemical studies of the rock mass and the orebody, as well as zircon LA-(MC) -ICP-MS U-Pb age, trace element and Hf isotopic characteristics of the biotite granite have been carried out.Biotite granite in the Guangming deposit is characterized by elevated SiO2, Al2O3 and total alkali contents, with A/CNK ratios of 1.07~1.14, showing peraluminous.Low-U zircons from three samples yield weighted average 206Pb/238U ages from 215 Ma to 218 Ma, indicative of Indosinian emplacement.The granite has zircon ages ranging from 237 Ma to 133 Ma, yielding three relatively concentrated age peaks at 230~210 Ma, 190~170 Ma and 150~130 Ma, indicating the influence of multi-stage magmatic activity.The biotite granite has strong Eu negative anomaly with weak positive Ce anomaly, being enriched in LILE(Rb, Th, U) and depleted in Ba, Nb, etc.The fluorite has moderate negative Eu anomaly with relatively depletion of Rb, Ba, Nb, Sm, Hf, Eu and enrichment of U, La, Nd, Zr, Y.The granite has εNd(t) values of -11.2 to -10.6 and the corresponding TDM2=1793~1837 Ma, while the fluorite has εNd(133 Ma) values of -11.3 to -10.0 and the corresponding TDM2=1741~1848 Ma.Hafnium isotope compositions showing a large variation, 176Hf/177Hf=0.282234~0.282420, εHf(133 Ma)=-16.70~-8.45, TDM2=1756~2214 Ma, indicating the crustal model age of Paleo-Mesoproterozoic.The comprehensive analysis suggests that the biotite granite in the Guangming deposit originated from the dehydration melting of muscovite in the mature crust, experienced multiple magmatic activities from Indosinian to Yanshanian.The biotite granite experienced strong differentiation and finally formed in an environment with low oxygen fugacity.The Yanshanian granite and the fluorite have similar characteristics of rare earth and trace elements, as well as the identical Nd isotopic compositions, different from Indosinian biotite granite, suggesting that fluorite mineralization in the Guangming deposit is related to the Yanshanian magmatism in the area.The ore-forming fluid is dominated by magmatic hydrothermal with minor addition of meteoric water.
