Title

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

Abstract

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.

Sections were characterized by Scanning Electron Microscopy (SEM) on a Quanta 650 at the University of Cambridge. Apatite and merrillite were distinguished on the basis of EDS measurements in point mode, with 10 s spectral acquisition times, based on the abundance of P, Ca, Na, Mg, and Cl. Panchromatic SEM-Cathodoluminescence (CL) images were collected on selected phosphate and plagioclase grains previously imaged in BSE, in order to obtain an initial view of crystal structure variability (crystallinity, evidence of recrystallisation, etc.) across the sample.U-Pb dating of apatite was carried out using CAMECA IMS 1280 ion microprobes at the Institute of Geology and Geophysics at the Chinese Academy of Sciences (IGGCAS) in Beijing and the NordSIMS facility at the Swedish Museum of Natural History.
