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 ：
作为研究洋壳俯冲和壳幔相互作用理想对象的新生代玄武岩在福建省从沿海至内陆均有分布，根据地理位置这些新生代玄武岩可分成闽西、闽中与闽东沿海三个区域。本文对这些玄武岩进行了系统的全岩主、微量元素以及Sr、Nd、Pb、Hf同位素研究。结果表明，这些新生代玄武岩主要为碱性玄武岩、碧玄岩和粗面玄武岩，结合前人研究资料，可见这些玄武岩自闽东向闽西具有年龄逐渐变小、碱性逐渐增加的趋势。Sr、Nd、Pb、Hf同位素揭示这些玄武岩具有亏损地幔(DMM)与EMⅡ型富集地幔组分混合的特征。闽东沿海玄武岩相较于闽西、闽中玄武岩具有更高的Sr、Pb含量，更低的~(143)Nd/~(144)Nd值和~(176)Hf/~(177)Hf值，更趋近于EMⅡ特征。从西至东富集组分EMⅡ的逐渐增多暗示陆源沉积物与俯冲效应有关，这些陆源沉积物极可能是由俯冲洋壳带入软流圈地幔的。整个新生代玄武岩的Zr、Hf、Ti负异常与Pb同位素组成特征指示俯冲沉积物中可能含有碳酸盐组分。闽中柳城地区玄武岩的喷发年龄与闽东沿海地区玄武岩的喷发年龄较为接近；闽中柳城地区玄武岩Sr、Nd、Pb、Hf同位素特征与闽中其他玄武岩的一致，这可能与太平洋板块俯冲导致的大陆边缘上地幔发生补偿性的隆起有关；柳城地区玄武岩具有较低的SiO_2含量及最高的CaO/Al_2O_3值，可能是源区受到俯冲再循环碳酸盐组分影响的结果。

Abstract ：
<正>福建省位于华夏块体东部,是中生代受太平洋西向俯冲作用影响最为明显的区域,在中生代经历了强烈的岩浆和构造活动,是研究中生代壳幔相互作用的理想区域。而基性侵入岩作为地幔部分熔融作用的直接产物,其地球化学特征可以直接反映地幔源区的性质,能为我们研究地幔源区组成及构造演化特征提供进一步的证据。本文分别在福建漳平、厦门、泉州、漳浦、福州以及南平等地区,采集了11件白垩世中-基性辉长岩、辉长闪长岩及闪长岩样品,进行了全岩主量和微量元素的分析,并对其中6件代表性样品进行Sr-Nd-Pb-Hf同位素测试。

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 ：
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 ：
The Cretaceous igneous rocks experienced a strong crust-mantle interaction and widely developed along the coast of Fujian Province, but the details of this tectonic-magmatic event are still controversial. We report detailed petrography, geochronology, and geochemistry of the Changanshan diorite and rhyolite in Fuzhou University, which provided new evidence for the correlation between crust-mantle interaction. Zircon U-Pb geochronology of diorites and rhyolites yield ages of 107. 2 +/- 0. 3Ma and ca 98. 6Ma, respectively. It indicated that they were formed in the late Early Cretaceous to early Late Cretaceous. The zircon epsilon(Hf) (t) values in the diorites and rhyolites are -2. 1 similar to + 0. 5 and -2. 7 similar to + 1. 1 , respectively. The rhyolites are characterized by rich silicon and alkali, poor calcium and magnesium, high fractionation indexes, and thus belonging to weakly peraluminous rocks. The rhyolites samples show prominent pattern of relative enrichment in LREE, and strong negative Eu anomalies, similar chemically to typical A-type rhyolite. The magma source of the rhyolites was likely produced by interaction of asthenosphere melts with subduction-influenced enriched mantle wedge, and experienced fractional crystallization in the crust. The petrogenesis of diorite may be the mixing of water rich mantle magma and felsic crust magma produced by mantle magma underplating. In combination with the regional tectonic setting, these rocks were probablely formed in continental arc setting related to the subduction of oceanic crust.

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.
