MacKay Glacier, Ordinary Chondrite

This specimen was one of three meteorites found on MacKay Glacier (Victoria Land, Antarctica) by the crew of an environmental organization in the summer season of 1990-1991.  Robert Elliott  purchased this stone from the finder around the year 2000. It exhibits unusual weathering, with a well-preserved fusion crust, but some oxidation related to salts, common for Antarctic specimens.

The Protocol for Environmental Protection of Antarctica was passed in 1991, which prohibits any commercial or national activity related to mineral resources on the continent for any purpose other than scientific research.  That said, the United States did not pass any related laws until 2003.  The details are visible here, and pertain to meteorites found after June 2003.

This fusion crusted individual weighs 59.9g and it appears to be an ordinary chondrite.
