简介：统计、典型年的作文方法被用来与ElNino和LaNifia事件在关系学习西北太平洋台风活动。结果显示台风趋于在ElNifio年里不活跃并且在拉·尼娜年和它里活跃也依赖于事件的发作和台风的开始的区域。与在频率和海面温度(SST)之间的ElNifio和拉·尼娜年和时间落后关联里的台风活动的频率的统计特征。有用信息被为台风出现的预言提供。另外，单个价值拆卸(SVD)方法被使用学习在重力势领域和SST地之间的关联。结果证明在ElNino年里的由空至海的联合是相反的让台风发展，它与一个更小的数字发生。相反的状况与拉·尼娜年被发现。

简介：典型地，Indosiniangraniticplutons产出的三的LA-ICPMS锆石U-Pb地球年代学为从在湖南的Xiema和Xiangzikouplutons的黑云母monzomitic花岗石的214.1+-5.9妈和210.3+-4.7妈的加权平均值~(206)Pb/~(238)U年龄省，并且为从Napengpluton的黑云母花岗石的205.3+-1.6Ma，，西方的Guandong省分别地，显示出结晶化的类似的迟了的Indosinian年龄。在有在华南块(SCB)以内的另外的geochronological数据fromIndosinian花岗石的联合，有约210妈和早Indosinian花岗石(230-245妈)的年龄的那些迟了的Indosiniangranites在相同构造背景有类似的岩石成因论，这被建议。在SCB以内的Indosinian花岗石可能是在压缩政体的变厚的外壳的深溶酌的产品。这些数据为Indosinian花岗石的时间、空间的分发和SCB的动态进化提供进一步的理解。

简介：对新疆和静县乔霍特铜矿一带巴音布鲁克组火山岩岩石学、岩石化学、岩石地球化学进行了研究总结,认为该火山岩为钙碱性系列的玄武安山岩-安山岩-英安岩-流纹岩组合,具低TiO2、MgO、高Al2O3,高Fe2O3/FeO比值及富钠贫钾的特点,形成于大洋岛弧环境;在流纹岩中获得（430.33±0.99）Ma的LA-ICP-MS锆石年龄,指示巴音布鲁克组时代为志留纪。

简介：斯弄多铅锌矿床位于南冈底斯-念青唐古拉成矿带北缘铅锌银多金属矿带上,该矿床铅锌矿化与矿区花岗斑岩密切相关,为典型的热液脉型-矽卡岩型铅锌矿床。为厘定其成岩成矿时代,本文对矿区花岗斑岩进行了锆石LA-ICP-MSU-Pb年龄测定。结果得到2组年龄,一组年龄介于(75.1±1.8)~(77.7±1.8)Ma之间,加权平均年龄为(75.7±0.9)Ma(MSWD=0.27,n=11),可能反映岩浆在岩浆房演化过程中结晶的锆石年龄;另一组年龄为(67.5±1.4)~(69.4±1.4)Ma,加权平均年龄为(68.8±1.2)Ma(MSWD=0.31,n=6),代表花岗斑岩真实的结晶年龄,这一花岗斑岩的年龄(68.8±1.2)Ma明显早于冈底斯带内主碰撞期形成的矽卡岩型矿床。结合该成矿带其他矿床的成岩、成矿年龄,本文认为南冈底斯-念青唐古拉成矿带在印-亚大陆碰撞早期或新特提斯洋壳俯冲晚期,也伴有较强的铅锌多金属成矿作用。

简介：天山东段古生代火山-沉积地层时代特别是变质事件的厘定对探讨天山古生代洋盆演化具有重要意义。本文首次对出露于哈密沁城地区的红柳沟组中的流纹岩进行了LA-ICP-MS锆石U-Pb测年,获得了锆石（U-Pb）年龄为（426±12）Ma（MSWD=0.31）,该年龄可以代表红柳沟组的沉积年龄。同时,获得变质锆石的加权平均年龄为（372±28）Ma（MSWD=0.021）,该期变质事件在天山普遍发育,可能与天山古生代洋盆碰撞有关。

简介：西准噶尔东部哈拉阿拉特山南麓乌尔禾地区新发现大量中基性岩墙群。岩墙群侵位于下二叠统佳木河组磨拉石建造中,展布方向与达尔布特大断裂延伸方向一致。岩墙群中采集的3个锆石U-Pb年龄样品测年结果分别为（286.3±4）Ma（n=18,MSWD=0.32,95%置信度）,（286.5±5.6）Ma（n=10,MSWD=0.3,95%置信度）和（283.6±2）Ma（n=6,MSWD=0.57,95%置信度）,误差范围内基本一致,据此确定该岩墙群形成于早二叠乌拉尔世（Cisuralian）亚丁斯克期（Artinskian）。中基性岩墙群具鲜明的与岛弧俯冲作用有关的地化特征,做为西准东部俯冲造山的地质记录,测年结果表明,西准东部的俯冲造山作用明显滞后于西部,整个西准地区俯冲造山作用结束的最终时限为早二叠世晚期。
