Abstract ：
福建新生代玄武岩广泛发育且携带了大量地幔包体,其矿物元素特征能够反演岩石圈地幔性质.本文对福建沿海的厦门及内陆地区的明溪、闽清等地新生代玄武岩及其橄榄岩包体中的矿物进行了电子探针、单斜辉石LA-ICP-MS微量元素和原位Sr同位素分析,探究福建地区岩石圈地幔属性特征及演化历史.结果表明:玄武岩及其橄榄岩包体中单斜辉石主要为透辉石,橄榄岩包体根据矿物学特征分为A、B两组,A组(Mg#＞90)代表了古老难熔岩石圈地幔,B组(Mg#＜90)代表了经改造后年轻饱满岩石圈地幔.A组橄榄岩包体中的单斜辉石高场强元素Nb、Ti轻微负异常,Hf、Zr、Ta强烈负异常.B组橄榄岩包体中的单斜辉石有所不同,高场强元素Zr、Hf轻微负异常,大离子亲石元素Ba强烈负异常.玄武岩斑晶和基质中的单斜辉石均呈现LREE富集、HREE亏损的特征,且单斜辉石斑晶边部比核部亏损高场强元素Th、Nb,富集大离子亲石元素Sr、Eu.橄榄岩包体中大部分A组和B组单斜辉石都经历了硅酸盐熔体交代,少数A组单斜辉石介于硅酸盐熔体交代和碳酸盐熔体交代之间.单斜辉石原位Sr同位素范围在0.702 57～0.703 67之间,大多单斜辉石边部的87Sr/86Sr值比核部要高,可能受到了高87Sr/86Sr值物质交代作用.福建橄榄岩包体很可能代表的是太平洋板块俯冲软流圈地幔经历减压上升后新改造的岩石圈地幔.

Abstract ：
Fluvial detrital zircons provide crucial insights into crustal evolution in the early Precambrian. We used U-Pb geochronology and the Hf-O isotopic compositions of detrital zircons from the Tingjiang River to determine the provenance and continental crustal evolution of the NE Cathaysia Block. The zircon U-Pb ages show seven major populations at 177-105, 262-200 and 520-376 Ma, with striking peaks at c. 422, 775-606, 1457-836, 2042-1710 and 2661-2300 Ma, corresponding to documented tectono-thermal events in the South China Block. Episodic magmatism was the response to the formation and break-up of the Columbia and Rodinia supercontinents. The episode at 422 Ma matches with the ages of widespread early Paleozoic intraplate orogenic events in the South China Block. The isotopic signatures of Hf and O in the detrital zircons indicate that the majority of the Precambrian zircons likely originated from remelted ancient continental crust, with contributions from juvenile mantle-derived magmas. The Phanerozoic zircons, by contrast, were formed through the partial melting of recycled crustal material. Analysis of crustal growth rates, based on the two-stage Hf model ages, suggests a significant presence of juvenile crustal growth during the Paleoproterozoic era. Specifically, it is estimated that c. 40 and 90% of the present crust within the NE Cathaysia Block was formed at c. 2.3 and 1.6 Ga, respectively.

Abstract ：
对福建省沿海至内陆出露的4件新生代玄武岩进行40 Ar/39 Ar年龄测试,对玄武岩中橄榄石斑晶进行电子探针测试;其中洋底和柳城玄武岩首次获得精确的40 Ar/39 Ar年龄数据.结果显示,闽西明溪40 Ar/39 Ar年龄数据为(1.44±0.11)Ma,柳城为(17.35±0.93)Ma;闽中洋底玄武岩年龄为(11.71±0.44)Ma;闽东厦门玄武岩年龄为(17.0±0.36)Ma.结合前人年龄数据,福建省新生代玄武岩整体表现出从闽东至闽西年龄逐渐减小的趋势.橄榄石斑晶电子探针数据显示闽东至闽西玄武岩碱性程度逐渐增加,可能指示岩浆熔融程度由沿海至内陆逐渐减少,岩石圈厚度由东向西逐渐增厚.最新获得的闽西柳城玄武岩40Ar-39Ar年龄为(17.35±0.93)Ma,与东部沿海玄武岩相似,推测可能是太平洋板块北西向俯冲时引起的岩浆扰动作用形成的.

Abstract ：
This study presents zircon U-Pb geochronology and Hf and O isotope data for granitic rocks in the Zijinshan ore field, southwestern Fujian Province, China. The intrusive rocks comprise monzogranite, granite and granodiorite. The magmatic zircon U-Pb ages from these granitic rocks can be divided into four episodes: episodes 1 (157.9-159.9 Ma) and 2 (141 Ma) in the Late Jurassic and episodes 3 (108.1-103.2 Ma) and 4 (97.5-99.7 Ma) in the Middle and Late Cretaceous, respectively. Patterns of rare-earth elements (REE) show enrichment in light REE and obvious negative Eu anomalies. These rocks are also enriched in Rb, Th, U, La, Ce, Nd and Hf, and depleted in Ba, Nb, Sr, P and Ti. The increasing La/Yb ratio and decreasing heavy REE content with decreasing age may imply an increasing contribution of mantle-derived materials from the Late Jurassic to Cretaceous. The zircon epsilon (Hf)(t) and delta O-18 values, ranging from -37.7 to -2.8 and 12.0 parts per thousand to 6.3 parts per thousand, respectively, indicate that the lower crust is an important source of granitic rocks. There was a significant increase in epsilon (Hf)(t) values and a decrease in delta O-18 values in the younger magmatic episodes (3 and 4), which ranged from -11.4 to -0.6 and 10.7 to 6.3 parts per thousand, respectively. This suggests an increasing contribution of mantle-derived magma to the crustal melts from the Late Jurassic to late Early Cretaceous in response to the changing regional tectonic setting from compression to extension and an increasing interaction between the crust and mantle.

Abstract ：
The mafic enclaves from Mesozoic intermediate-acid magmatic rocks, widely developed along Fujian coast, are considered to be the results of large-scale crust-mantle interaction and magma mixing. In this paper, petrography, mineralogy, and geochemistry of granites and mafic microgranular enclaves (MMEs) in Langqi Island are studied to provide new information for tracing crust-mantle interaction. The zircon U-Pb dating results show that the Langqi rocks were formed at similar to 101 Ma, which are metaluminous, enriched in silica and high-K calc-alkaline I-type granites. The enclaves have a typical magmatic structure, which is characterized by magma mixing between high-temperature basic magma and low-temperature acidic magma through injecting. The enclaves and host granites show a tendency to mixed major and trace elements, displaying a clear-cut contact relationship, which is indicative of coeval magmatism. The genesis of Langqi rocks is related to the extensional setting caused by the subduction of Paleo-Pacific Plate, and they are the results of mixing of subduction-related metasomatized mantle-derived mafic and induced crustal-melted granitic magma originating from partial melting of the crustal material.

福建沿海广泛发育的白垩纪岩浆岩壳幔相互作用强烈,但对其构造-岩浆事件的细节过程仍存争议。本文对福州闽侯地区福州大学校园内的长安山闪长岩和流纹岩进行了岩石学、同位素年代学和地球化学研究。LA-ICP-MS锆石U-Pb定年结果表明长安山闪长岩年龄为107. 2±0. 3Ma,形成于早白垩世晚期;流纹岩的形成年龄为98. 6Ma左右,属晚白垩世早期的产物。闪长岩和流纹岩的锆石ε_(Hf)(t)值分别为-2. 1～+0. 5和-2. 7～+1. 1。流纹岩具有富硅、富碱、贫钙镁、高分异指数等特点,属弱过铝质岩石。轻稀土富集而重稀土亏损,具有明显的负Eu异常,部分样品具有A型流纹岩的亲缘性特点。流纹岩的...

Abstract ：
Mesozoic porphyritic rocks from the Zijinshan area, southwestern Fujian Province, China, are andesitic to rhyolitic in composition. The whole-rock SiO2 contents of these rocks are between 62.5% and 78.1%. Magmatic zircon from the Mesozoic porphyritic rocks was determined via secondary-ionization mass spectrometry (SIMS) for the U-Pb age and Hf and O isotopes. The zircon U-Pb ages could be mainly divided into three age groups: Group 1: similar to 138.8 Ma; Group 2: 109.2 similar to 107.4 Ma; and Group 3: 99.7 similar to 98.2 Ma. The epsilon Hf(t) and delta O-18 values of the porphyritic zircons showed that the porphyritic rocks in Group 2 were more affected by mantle-derived magma. Combined with previous research results, the medium-acidic magmatism in the southwestern Fujian Province can be divided into eight periods: Paleoproterozoic, Mesoproterozoic, Middle Neoproterozoic, Silurian to Lower Devonian, Permian to Triassic, Middle Jurassic to early Lower Cretaceous, late Lower Cretaceous, and late Lower Cretaceous to early Upper Cretaceous. The Paleoproterozoic crust was the predominant magmatic source for the subsequent Mesoproterozoic to Jurassic magmatism, but the only melts that were closely related to mineralization were derived from partial melting of the Mesoproterozoic crust and a more depleted upper mantle.

Abstract ：
通过对福建紫金山地区不同岩石样品中岩浆锆石的 SIMS U-Pb年龄和 Hf、O同位素研究，对该地区岩浆序列以及源区组成、壳幔相互作用等进行初步探讨。结果显示，岩石样品中岩浆锆石的年龄（151～1514Ma）较为分散，包含了从中元古代、震旦纪、早古生代晚期、晚三叠世到晚侏罗世的5个不同岩浆侵入时期。锆石的二阶段 Hf亏损地幔模式年龄（tDM2值）主要分布在古元古代，εHf（t）数据也显示主要沿基性地壳演化线分布，指示古元古代时期的新生基性地壳可能是研究区中元古代直至晚侏罗世侵入岩形成的主要源区。锆石δ18O 及εHf（t）值显示中元古代及震旦纪岩浆作用是幔源岩浆与古元古代基性地壳共同作用的结果；早古生代晚期和晚三叠世岩浆作用以壳源为主；至晚侏罗世，亏损地幔物质对岩浆作用的影响增加。
