FOV 1.3 x 1.7 mm. Via Jean-Pierre Beckerich This specimen has a checkered past as far as ID is concerned. Suffice it to say that it has now been positively IDat the ROM as tundrite-(Ce) using long exposure XRD and EDS comparison with other known MSH tundrite specimens The terminations on these xls look different from the "dagger" shape shown in Min Rec May/June 2007 p. 236. (This is what set off the circle of angst and confusion.) That said, this is an old and not very good photo - only partly beciause the crystals are so small.
