Pallasite, Main group
Find 1868, 159.2 kg, weathered
The Mount Vernon Pallasite was found about 7 miles (11 km) NE of Hopkinsville in 1868, but was not recognized as a meteorite until 1902. Like all Pallasites its two principal constituents are olivine (78 vol%) and Fe-Ni metal (18 vol%). As a βmain groupβ Pallasite its Fe-Ni metal is ~11.5 % Ni and its olivine is forsteritic (Fa12). A few additional more or less expected constituents have also been recognized (e.g., schreibersite, troilite, chromite). Unfortunately, lawrencite and limonite due to terrestrial weathering [exacerbated by a couple of decades use of the exposed mass as a rubbing post] complicates interpretation of the original form.
Mount Vernon is the second most massive of 25 meteorites recovered and is β along with Eagle Station β one of the two Pallasites recovered in the state. The main mass is with the United States National Museum in Washington, D.C.
