- Concept maps for mineralogy. This visual method can be used as a way to organize and link information. (See Dyar et al. (2004) JGE, 52, 23-30 for details.)
- The following two examples are videos recorded for the NSF-Teaching Mineralogy workshop at Smith College. They both use the spindle stage to show correlations of optical properties in plane- and cross-polarized light as well as conoscopic illumination.
uniaxial crystal A crystal of eudialyte with perfect (001) cleavage with its c-axis mounted perpendicular to the spindle axis.
biaxial crystal A crystal of gypsum with perfect (010) cleavage and b=Y, with its b axis mounted parallel to the spindle axis.
- Crystal structure movie of ice, showing two different types of bonding. A movie of a zeolite undergoing dehydration . The movies were made with CrystalMaker, a Mac application for representing crystal structures of materials. I'm in the process of making 300-400 of these for an intro mineralogy book written jointly with Darby Dyar; I'll demo some of them at the workshop.
