新疆西准噶尔造山带发育大量的晚古生代侵入岩,但它们的岩浆源区和形成的构造背景仍然存在较大争议。本文对西准噶尔造山带北部阿尔加提山石英二长岩进行了详细的岩石学、地球化学、锆石Hf-O同位素研究,旨在揭示其岩石成因和构造背景,探讨其与地壳生长的关系。两件样品的锆石U-Pb定年结果分别为3.1.8±1.4 Ma和3.3.7±3.1.Ma,形成于晚石炭世。阿尔加提山石英二长岩样品含有角闪石,高硅(SiO_(2)=67.8%~68.9%)、富碱(K_(2)O+Na_(2)O=9.3.%~9.89%)、具有低的铝饱和指数(A/CNK=0.96~1.00),伴有低的Ga/Al值(2.27~2.3.),Rb/Sr值(0.3.~0.50),显示出I型花岗岩的特征。同时,这些样品均富集大离子亲石元素和轻稀土,亏损高场强元素(如Nb、Ta和Ti等),和负的Eu异常(δEu=0.72~0.85),类似于典型俯冲相关的岛弧岩浆特征。这些I型花岗岩具有高的、正的锆石ε_(Hf)(t)值(+1..2~+1..5)和年轻的二阶段Hf模式年龄(t_(DM2)=604~3.2 Ma),以及比地幔值略高的锆石δ^(1.)O值(5.73.~6.51.)和高的锆石饱和封闭温度(T_(zr)=854~895℃),可能是新生下地壳在高温背景下部分熔融的产物。结合前人在西准噶尔造山带北部发现的晚石炭世早二叠世A1.A2型花岗岩和埃达克质岩墙,本文认为这些高温岩石组合的形成可能与晚石炭世的洋中脊俯冲及其相关板片窗作用有关。在洋脊俯冲背景下,软流圈地幔上涌加热新生下地壳,促使其发生部分熔融形成I和A_(1.和A_(2)型花岗岩。西准噶尔造山带大多数下地壳主要形成于早古生代,表明该地区在显生宙发生了显著的地壳增长。

全国第十三次光纤通信暨第十四届集成光学学术会议

作者： zhang bo(1., LIU {1.(1.2), chen long(1. (1. Accelink Technologies Co., Ltd, Wuhan Research institute of Post and Telecommunications, Wuhan, 43.074, china 2.Wuhan National Laboratory For Optoelectronics, Huazhong University of Science and Technology, Wuhan, 43.074, china )

The PDL and WDL of micro-optical components are analyzed in this paper. When the input light with different wavelength pass through an aperture, it will produce corresponding spot sizes which will bring different loss, so Insertion Loss (IL) and WDL are influenced. When the input light is split inside the components and the splitting ratio is polarization dependent, because of the drift and asymmetry between the aperture and spot centre, divisive optical pulses will have different loss and the PDL will be influenced.
