No. 45: May-Jun 1986
The thousands of meteorites rescued from the Antarctic ice are markedly different from those collected elsewhere on our planet. First, the Antarctic collections contain rare types that seem to have come from the moon and perhaps Mars. Second, the trace elements in the Antarctic specimens differ substantially from those found elsewhere. Age is a third distinguishing parameter. The Antarctic specimens seem to have been residing on and in the ice for some 300,000 years. Almost all meteorites collected elsewhere are less than 200 years old, having been picked up soon after they fell. The implication is that those extraterrestrial projectiles that have accumulated in Antarctica had a different source.

Comment. A dedicated catastrophist would ask what extraterrestrial event occurred 300,000 years ago? Did it involve the moon? Was terrestrial life, including humans, affected?
