Northwest Africa 1827
Type C Mesosiderite
Found 2003
Morocco

I did a bit of looking into the differences in Meso Types A, B, C with Dr Ted Bunch at NAU and DR. Alex Ruzicka with Cascadia Meteorite Lab The difference lies in pyroxene differences:

TYPE A plagioclase>Ca-pyroxene> orthopyroxene
TYPE B clinopyroxene>plagioclase>orthopyroxene
TYPE C abundant orthopyroxene with traces of Ca-pyroxene and plagioclase

and the implication suggests a NEAR-SURFACE ORIGIN in Type A toward A DEEPER ORIGIN FOR Type B and C (going deeper) though the differences are not yet fully studied.

NWA 1827 and a few paired stones represent the only available Type C Mesosiderite available in the world

Much went to science, much was lost in preparation. If you think you've seen them all then look again, a busy brown, green, yellow crystalline matrix, and a whole lot of metal.
