 实验室简介  

⁴⁰Ar/³⁹Ar和(U-Th)/He年代学实验室拥有多台先进的稀有气体质谱仪和激光探针系统，是国内重要的年代学和热年代学研究平台。⁴⁰Ar/³⁹Ar法是年代学中的重要手段，测年范围从46亿年的陨石到数千年的火山岩，研究领域从行星演化到地球动力学，从古环境与气候到考古研究，从岩浆活动到板块运动，从元素运移到成矿机制等，涉及到地球与行星科学的各个方面；测年物质广泛，几乎涵盖了所有的的含钾矿物；测年精度高，是确定地质年表及地磁极性年表时标的主要手段。  (U-Th)/He是近二十年来快速发展起来的低温（热）年代学方法，其成功应用大大延伸了中低温热年代学（如⁴⁰Ar/³⁹Ar，裂变径迹）的温度下限，使其在新构造地质、地貌演化、环境变迁等重大地质问题的研究中具有广阔的应用前景。

    长期以来，我们始终把提高定年精度作为主线，加强优势领域的研究，发挥⁴⁰Ar/³⁹Ar法的独特优势，拓展新的应用方向，建立新的国际标准样品，建设高水平的实验室平台。目前实验室超低的本底水平使得我们能进行微量样品的定年及（超）年轻样品的⁴⁰Ar/³⁹Ar定年，成为实验室的重要特色之一；同时秉承理论-实验-模拟的理念，发挥⁴⁰Ar/³⁹Ar热年代学定量的优势，为地质过程热历史的恢复提供最佳模拟手段，进而为深部动力学机制研究提供定量制约。近期结合特提斯演化这一综合科学问题，实验室培育了造山带演化、成矿机制、新生代地貌地形演化历史研究等重要发展方向。

实验室自建立伊始，一直坚持开放共享的理念，成为全球开放的年代学和热年代学知名研究平台，为国内外的地质学家提供了广泛的实验研究；鼓励学生和研究人员到实验室开展研究工作，实地参与样品分析、数据处理和结果解释；广泛参与国际交流，2013年成功举办了Ar-Ar和(U-Th)/He国际研讨会，主持了由澳大利亚Curtin大学、法国国家科研中心、台湾大学、法国蒙彼利埃大学等Ar-Ar实验室参与的国际实验室对比标定计划。

 工作内容 　　

　　本实验室主要进行如下方面的分析测试工作：

　　实验室建立了完整的Ar-Ar和(U-Th)/He年代学技术体系。其中Ar-Ar定年包括常规阶段升温技术，激光阶段升温技术，单颗粒矿物的激光全熔或阶段升温测定，激光微区原位（通常10-50微米）定年，定年矿物涵盖碱性长石、斜长石、云母，角闪石等常见造岩矿物及火山岩基质，为满足不同地质研究的需求有针对性的设计了相应的实验流程。(U-Th)/He定年方法目前主要包括磷灰石和锆石的单颗粒溶液法定年，锆石的激光原位(U-Th)/He和U-Pb双定年。

　　主要应用领域：

　　（1）火山岩及火山沉积地层定年：快速冷却的火山岩是40Ar/39Ar法定年的良好对象,为地层划分和地磁极性确定以及火山活动提供有效的研究手段

　　（2）构造－热年代学：利用不同矿物的封闭温度及封闭时间和同一矿物中多重扩散域特征，建立中上地壳侵入岩及变质岩的冷却历史，进而探索岩体的抬升过程。发挥Ar-Ar和(U-Th)/He的优势，恢复地质体的抬升和冷却历史、地形的演化过程

　　（3）微区年代学：结合聚焦<10μm的紫外激光探针测定单颗粒矿物中气体同位素浓度分布，进而探索年龄分布，为反推地质体热历史和变质变形过程提供有力的微区研究手段

　　（4）稀有气体（如He、Ar）扩散机制的研究，探索气体扩散和温度的关系、矿物封闭机制，架起实验和地质过程的桥梁

送样要求及联系人：

　　Ar-Ar定年送样要求：

　　新鲜含钾矿物（如碱性长石、斜长石、云母、角闪石、火山岩基质等），粒度40-60目或60-80目，样品纯净，重量100mg以上，特殊矿物定年、原位微区定年和超年轻地质体定年请联系实验室工作人员。

　　联系人：师文贝，shiwenbei@mail.iggcas.ac.cn， 010-82998560

　　（U-Th）/He定年送样要求：

　　样品分析采用单颗粒熔融法，每个样品分析3-5个颗粒，   测试矿物主要为磷灰石和锆石。要求矿物晶体新鲜、自形好，磷灰石和锆石宽度通常不少于70微米，长度大于100微米。每个样品要求20-50个自形晶体颗粒。如需进行锆石(U-Th)/He和U-Pb双定年，用户需自行制靶（Teflon靶，环氧树脂锆石靶在提取4He时会影响系统的真空度以及本底）并拍摄阴极发光图像，并且自行选取激光剥蚀位置。为获得颗粒完整的磷灰石或锆石，鼓励用户亲自碎样、选矿。
