While these can be toxic, the dose required to induce a toxic reaction is exceptionally high. Figure 5.4 above shows a microscope view of a thin section that contains several minerals Another kind of twinning, called penetration twinning, appears as crystals that seem to have grown through each other. Presented by the Mineralogical Society of America Crystal twinning occurs when two or more adjacent crystals of the same mineral are oriented so that they share some of the same crystal lattice points in a symmetrical manner. It has a bright silver luster and is reasonably stable in air.

The result is an intergrowth of two separate crystals that are tightly bonded to each other. On the other hand, rubies do have double refraction. The liquidus curves, that make up the bottom of the red field, separate the region where all is melted, from fields of partial melt. Zeolites therefore have both ionic crystal and covalent crystal (ANA): analcime, leucite, pollucite, wairakite; Laumontite (LAU), yugawaralite (YUG), goosecreekite (GOO), montesommaite (MON) 09.GC. e.g., phase transitions in quartz, cristobalite and leucite; structural views (cages, chains), etc. Diopside and hedenbergite are important endmembers in augite, but augite can also contain significant aluminium, titanium, and sodium and other elements.
