Transmission Electron Microscopy (TEM) data for fine-grained matrix in the unequilibrated ordrinary chondrites (UOCs) Bishunpur (LL3.15) and Ngawi (LL3.1-3.7). Included in the parent folder are:

  • Amorphous EDS.xlsx - data file containing energy dispersive spectra (EDS) determined element compositions of regions of amorphous silicates, identified by TEM.
  • EDS Data all.xlsx - data file containing element compositions of all the regions which underwent EDS collection.
  • Plots - Folder containing (where available) interactive plots.
  • Ngawi (folder)
  • Bishunpur (folder)

The Ngawi and Bishunpur folders contain the following sub-folders and documents:

  • [NAME] Gatan files - Folder containing the raw .dm4 files which can be opened and analysed using the GATAN micrograph software
  • [NAME] tiff files - Folder containing .tiff images of both annular bright-field (ABF) and annular dark-field (ADF) images.
  • Data - Folder containing raw .dat files of elemental compositions, determined using X-ray maps and EDS.
  • Processed data - Folder containing X-ray maps and numerical EDS data for different regions of the focused ion beam (FIB) sections.
  • ABF [NAME].png - Compiled image of the whole FIB section in Annular Bright Field (ABF).
  • ADF [NAME].xcf - Compiled image of the whole FIB section in Annular Dark Field (ADF).
  • ADF [NAME].xcf - GIMP file of the individual ADF images combined to make the whole FIB section image, as well as aligned and overlaid X-ray maps onto the section.
