This is a micro. The “eudialyte” pseudo-octahedra are <= 0.6 mm on edge. You will need 15-30X to see them clearly. But under the scope, they are very pretty. The hand held color is bright pink. The color in the last three micro close-up photos is somewhat too saturated because my camera sensor loves red and because the snow-white pectolite tricked the auto-exposure into underexposing the eudialyte. The color in the first close-up photo and the macro photo is more accurate. FOV in the close-up photos is, resp., 3.3 x 2.1, 2.4 x 3.7 mm, 5.8 x 4.4 mm and 6.7 x 4.1 mm. The label claims makatite rather than pectolite, and it is easy to see why. But igneous breccia is the wrong environment for makatite, whereas this type of pectolite is common there. In any case, the UV responses of pectolite and makatite are very different. Note: These crystals look similar to verified manganoeudialyte. But it is impossible to visually distinguish the various eudialyte group members at MSH. In general, even semi-quantitative EDS does not suffice. Many xls are zoned. At a minimum, WDS is required – expensive! In any case, I don’t think that manganoeudialyte has been reported from breccia. You’re on your own if you want to go beyond “eudialyte group”.
