The 3rd iron meteorite in Gale - Egg Rock

We have found an iron meteorite - called Egg Rock.  Curiosity was close enough to determine that it is composed of iron, with some nickel.The textureson the urface shows regmaglypts wher the atmosphere ablated the iron. It seems to have s fresh, unweathered surface suggesting it fell relatively recently in the Mars past, long after the underlying sediments were exposed and eroded.

This is the 3rd iron meteorite we have found in Gale - the others were analysed (without ChemCam LIBS) on sol 640 - Lebanon and Littleton.
