Lunar crystalline matrix breccia

Lunar Crustal Material similar in composition to the surprising recovery of the Genesis Rock brought back by Apollo 15

4.27 billion years old!

- almost as old as Earth's Moon itself!

1 stone of  34,4g was found 11th of August 2001

Dhofar 489 is mineralogically different from other known Dhofar lunar meteorites: It is a feldspathic fragmental breccia consisting of clasts of various lithologies embedded into a fine-grained crystalline matrix. . Very low 10Beand 41Ca concentrations are similar to that of Dhofar 026 which was found 80 km apart. The ejection depth was more than 1100 g/cm2 on the Moon. The transition time was 6±2 kyr.
