L chondrite meteorite phosphate microscopy and U-Pb analyses (NERC Grant NE/L002507/1)

Microscopy (Scanning Electron Microscopy, Cathodoluminescence Imaging) and U-Pb isotopic (Secondary Ionisation Mass Spectrometry) analyses of phosphate minerals in a suite of nine L chondrite meteorites (and one reference analysis of an LL chondrite). The dataset includes multiple SIMS spot analyses of phosphates in each meteorite, as well as images at multiple scales of all grains analysed. The data is reported and analysed in Walton et al., 2022 GCA.

对九块L型球粒陨石（及一块LL型球粒陨石的参考分析）中的磷灰石矿物进行显微镜（扫描电子显微镜、阴极发光成像）及U-Pb同位素（二次离子质谱仪）分析。数据集包含每块陨石中磷灰石的多次SIMS点分析，以及所有分析颗粒的多尺度图像。数据及分析结果在Walton等人2022年的GCA论文中予以报道。
