在过去的十年中，U-Pb地质年代学的精度和准确性的重大进步，这源于改进的样品预处理和完善的测量技术，揭示了以前无法解决的差异之间的分析从不同的实验室。评估和解决这些差异的一个解决方案是采用一个通用的软件平台，该平台可以简化数据处理协议，从而实现强大的实验室间比较。我们提出了合作的结果，开发网络基础设施的高精度U-Pb地质年代学的基础上分析辅助矿物同位素稀释-热电离质谱。这一网络基础设施实施了一种架构，具体规定了数据采集、统计过滤、分析和解释、出版、社区存档以及汇编和比较来自不同实验室的数据的工作流程。网络基础设施的骨干由两个开源软件程序组成：Tripoli和U-Pb_Redux。Tripoli使用标准化协议、统计过滤和交互式可视化功能与商用质谱仪连接，帮助分析人员准备原始数据，以便在U-Pb_Redux中进行分析。U-Pb_Redux通过使用交互式可视化编排分析师的工作流程来实现该架构，并提供支持数据解释的数据减少和不确定性传播。最后，U-Pb_Redux可以生成可供出版的图形和数据表，将结果存档，并对存档结果进行比较汇编，以支持合作科学。
In the past decade, major advancements in precision and accuracy of U-Pb geochronology, which stem from improved sample pretreatment and refined measurement techniques, have revealed previously unresolvable discrepancies among analyses from different laboratories. One solution to evaluating and resolving many of these discrepancies is the adoption of a common software platform that standardizes data-processing protocols, enabling robust interlaboratory comparisons. We present the results of a collaboration to develop cyber infrastructure for high-precision U-Pb geochronology based on analyzing accessory minerals by isotope dilution-thermal ionization mass spectrometry. This cyber infrastructure implements an architecture specifying the workflows of data acquisition, statistical filtering, analysis and interpretation, publication, community-based archiving, and the compilation and comparison of data fromdifferent laboratories. The backbone of the cyber infrastructure consists of two open-source software programs: Tripoli and U-Pb_Redux. Tripoli interfaces with commercially available mass spectrometers using standardized protocols, statistical filtering, and interactive visualizations to aid the analyst in preparing raw data for analysis in U-Pb_Redux. U-Pb_Redux implements the architecture by orchestrating the analyst's workflow with interactive visualizations and provides data reduction and uncertainty propagation that support data interpretations. Finally, U-Pb_Redux enables production of publication-ready graphics and data tables, the archiving of results, and the comparative compilation of archived results to support cooperative science.
