1西天山艾肯达坂组火山岩系的元素地球化学特征和构造环境显示文摘 西天山二叠纪艾肯达坂组红色陆相火山岩建造不整合在下石炭统大哈拉军山组之上,未经变形和变质。主要岩石类型有粗面玄武岩、玄武粗安岩、粗安岩、粗面岩和粗面英安岩,w(SiO2)介于41.69%~65.99%,低于上陆壳平均成分(66%)。w(Na2O+K2O)随SiO2增加而增加;SI随SiO2增高而变小;w(TiO2)一般小于1.3%;w(Al2O3)较高(12.82%~18.37%),由此显示艾肯达坂组属于典型的橄榄安粗岩系。其中,玄武岩和玄武粗安岩的w(SiO2)低于54.4%(下陆壳平均值),表明它们应源于地幔,而非陆壳;相反,w(SiO2)>54.4%的粗安岩、粗面岩和粗面英安岩可能来自陆壳或经历了壳内分异作用。玄武岩类和玄武粗安岩类ΣREE,LREE,Zr,Hf,Nb,Ta,Ba,Sr,Pb,Y等的质量分数和LaN/YbN均高于世界同类岩石平均值,而Cr,Co,Ni等的质量分数低于同类岩石,指示源区地幔富集大离子亲石元素(LILE)和不相容元素;玄武岩类和玄武粗安岩类的Eu/Eu*<0.94,Sr由亏损变化到正异常,显示地幔源区成分不均一,此不均一性可能由上壳物质返回地幔所致。粗面岩和粗面英安岩Eu/Eu*平均0.59,低于上陆壳平均值0.65;Sr亏损显著;但ΣEEE,LREE,LREE/HREE,LaN/YbN,Ce/Ce*反而低于粗安岩;Sm/Nd平均值为0.25,与下陆壳(Sm/Nd=0.25)相一致;La,Ce,Nd,Sm等相对于Y和Yb富集;Ba正异常,Nb,Ta,Hf等?陈衍景 鲍景新 张增杰 刘玉琳 陈华勇 蔡文俊 Herb Helmstaedt 2004矿物岩石2004,24,3:27
2西天山艾肯达坂组火山岩系同位素定年及其构造意义显示文摘 西天山艾肯达坂地区较好发育了艾肯达坂组红色陆相火山岩建造,它不整合在下石炭统大哈拉军山组之上,未经变形和变质,属于陆陆碰撞晚期的橄榄安粗岩系,其年龄确定是厘定从碰撞造山向陆内构造演化的关键。因此,通过16件新获得的钾氩年龄测值,确定艾肯达坂组火山岩系形成在260Ma~270Ma之间,属早二叠世,而不是过去认为的石炭纪;西天山的陆陆碰撞应在二叠纪末结束,此后进入陆内造山阶段。陈衍景 刘玉琳 鲍景新 张增杰 陈华勇 蔡文俊 Herb Helmstaedt 2004矿物岩石2004,24,1:11
3Screening of Epstein-Barr Virus Early Antigen Expression Inducers from Chinese Medicinal Herbs and Plants显示文摘Ether extrilcls of 1693 Chinesc medicinal herbs and plilnts from 268 families werestudied for the induction of Epstcin-Barr viral (EBV ) early antigcn (EA ) expression in theRaji cell line. Fifty-two from 18 families were found to have inducing activity. Twenty-fiveand seven of them were from Euphorbiaccae and Thymclaeaceae, respectively. Some ofthem, such as Croton tiglium, Euphorbia kansui, Daphnc genkwa, Wikstrocmia chamacdaphen, Wikstroemia indica, Prunus mandshurica Koehne and Achyranthes bidentata arecommonly used drugs. The significance of these herbs in the activation of EBV in vivo andtheir relation to the development of nasopharyngeal carcinoma were discussed.ZENG YI ZHONG JI AN-MING YE SHU-QING NI ZHI-Yu MIAO XUL-QIAN MO YONU-KUN AND LI ZE-LIN(Institute of Virology, Chinese Academy ’ of ’Preventive Medicine, Beijing,)(Nasopharyngeal Control and Treatmenl Institute of Cangwu, Guangxi,Guangxi Herbs Bitany 1994Biomedical and Environmental Sciences1994,7,1:3
