资源简介:

This dataset contains the results of 11 individual (U-Th)/He analyses using zircons extracted from bedrock samples collected from medium-high grade metamorphic rocks along the Api transect in the far western Nepal Himalaya. Bedrock samples were collected for thermochronologic cooling ages to better constrain the exhumation history of the Nepal Himalaya. Analytical methods followed the general procedures outlined in Reiners (2005) and Reiners et al. (2004). The ZHe Data Summary includes the mean age for each samples, calculated from three zircon grains, and an error that spans the range in measured ages and includes a 2σ analytical error.

本数据集包含11次独立的(铀-钍/氦)[(U-Th)/He]锆石定年分析结果,所用锆石采自尼泊尔喜马拉雅西部远端Api剖面沿线的中高级变质岩基岩样品。本次采集基岩样品旨在获取热年代学冷却年龄,以更精准地约束尼泊尔喜马拉雅的剥露历史。分析方法遵循Reiners(2005)及Reiners等(2004)所概述的通用实验流程。本次锆石(U-Th/He)定年(ZHe)数据汇总包含每个样品的平均年龄(由3颗锆石颗粒计算得到),以及覆盖实测年龄区间、包含2σ分析误差的误差范围。
