Statement

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.
