If a rock is full of amygdules, then it is not a meteorite.

These rocks are not meteorites, they are amygdalar terrestrial volcanic rocks. The vesicles have been filled in by secondary minerals (quartz, calcite, others) after the magma solidified.

Amygdules have been found in meteorites from hot deserts. They formed after the meteorite landed on Earth from the meteorite being exposed to salt-rich fluids. Because vesicles are not prevalent in meteorites, neither are amygdules.
