Impact Melt Breccia IMB

El Kachla , NWA 722 

Found in April 2000

  TKW :1,280 kg + 2.8Kg in 4 individuals recently discover

 

Impact melt breccias are the result of a major shock between asteroids and parent bodies. They can be of a chondritic or an achondritic source, they range from simple shock veins up to complete melting of the rock source (over 20 GPa).
NWA 722 presents all these stages and sometimes in the same individual, this meteorite is of interest because it's one of the best-preserved IMB chondrites available. What makes it spectacular is that in most case, metal flows are visible
within the melted part surrounding the partially melted islands...
NWA 722 00

Wonderful half stone with crust showing the original chondrite, fully melted matrix...
