H2O, LdS2 case) or latiumite ( (Ca,K)8 (Si,Al)10O22 (SO4,CO3), LdS7 case). Many references describe cancrinite as consisting of silica "cages" enclosing other anions and cations, but that's a poor description of the structure. Colour and Pleochroism. The cover slip is very thin and delicate, so make sure you are very careful not to crack the slip.

Type Material: Vernadsky Geological Museum, Moscow; A.E. Faceted gems even as small as 1 carat are considered great rarities. Cancrinite loses water continuously until about 625 C; thereafter an anhydrous cancrinite phase exists. It is classed as a member of the feldspathoid group of minerals; the alkali feldspars that are poor in silica. Use a pencil eraser to gently slide around and remove bubbles.

Anorthoclase: The feldspar mineral Anorthoclase information and pictur Cancrinite --MIROFOSS-- In thin section andalusite sometimes shows a pale pink pleochroism and if seen is fairly diagnostic. Judge birefringence by the highest color you see for that mineral, and check minerals with somewhat higher birefringence if you can't find an exact match. From 25 to 952 C, a minimal amount of CO 2 is lost from the structure. 2H 2 O, a zeolite-like mineral, is the parent of homonymous mineral group which includes 25 minerals with 13 types of frameworks [1], [2], [3]. The epoxy ideally has an index of refraction of 1.54, although . In thin section, calcite can be distinguished by its parallel extinction. Point Group: 6: Rarely as prismatic crystals, terminated by a low pyramid, to 2 cm; commonly massive.
