Hi Charlie and Mike, hello List, ... which makes it just as interesting, meteoritically speaking, as that new olivine diogenite NWA 1459 and I am glad I own a thin but beautiful 0.5-gram partslice with a large viewing area of the NWA 1109. My little specimen looks like the "Bunte Brekzie" (colored breccia) you find in the Otting Quarry (Ries Crater, Germany). Now, what makes it so very interesting, apart from its visual appeal, is the fact that it must have originated somewhere on its parent body - that somewhere being a "spot" where basaltic flows (eucrites) were close to plutonic rocks (diogenites) - not far away from either of these (boundary layer ? ... a word we usually associate with the K-T extinction event).
