Were you able to ascertain from their talk what methods and methodologies they used to search, collect, and identify their meteorites? If they were looking for dark metallic chunks with a bit of surface melting, or using a metal detector or dragging magnets behind them, then we can quickly guess that their results are so low for that reason alone. | |
