A meteorite mystery from Mercury?St. Louis, MO (SPX) Apr 06, 2013 Early in 2012, someone in Southern Morocco picked up 35 greenish stones, including the one shown above. Purchased by a dealer in Erfoud, Morocco, it was then resold to Stefan Ralew, a meteorite collector from Berlin. The dealer was demanding a high price, and Ralew may have hesitated. But the wrinkled glassy coating on one face of the rock was clearly a fusion crust, a kind of glaze that forms when a meteorite is heated as it passes through the atmosphere. Looking at other faces he would hav ... read more |
