Step Chronology Date Type Process Changes #1 before layer formation 2021-01-01 mechanical grinding bulk meteorite (20-30 mg) reduced to grains with size lower than 10 microns #2 before layer formation 2021-01-01 chemical chemical leaching to remove minerals related to terrestrial weathering bulk meteorite (10mg) cleaned from terrestrial weathering products - see Krämer Ruggiu et al. (2021) for details on the chemical protocol #3 before layer formation 2021-01-01 thermal 300 mg of commercial ultrapure KBr powder was heated under ambient air to 80°C overnight (~10h) removal of adsorbed/hydration water in KBr powder #4 before layer formation 2021-01-01 mixing homogeneous mixing 1.0 mg of grinded and leached meteorite was weighed and mixed with 300 mg of dried commercial ultrapure KBr powder #5 during layer formation 2021-01-01 pressure pressure formation of a pellet of 13mm diameter and 0.8 mm thick under 400 bars of pressure
