Moroccan meteorite might have come from Mercury but more study needed
An achondrite meteorite found in southern Morocco has some features that hint at a Mercury origin but has other features that argue against it. So it’s origin remains uncertain: A meteorite mystery: Could this stone be the first meteorite from Mercury ever found? WUSTL’s meteorite expert sifts the evidence – Washington University in St. Louis
Most meteorites are stony, he explains, and of the stony meteorites, almost all (90 percent) are what are called ordinary chondrites. These are pieces of small, unmelted asteroids that are uniform in composition throughout.
The achondrites, on the other hand are pieces of large asteroids or planets, ones at least 200 kilometers in diameter. These produced enough internal heat early in their history to partially melt and segregate into a metal core surrounded by a rocky exterior. Achondrites, which come from the crust or mantle of these differentiated bodies make up only 5 percent of the stony meteorites that have been found.
