An optical material encountered during ongoing field collection activities displays tenebrescence, fluorescence
and photo-refractive properties. The material is an uncommon variety of sodalite called hackmanite. It is part of the
tectosilicate family, a type of silca-based polymer structure, which was discovered to accommodate two separate dopant
sites within close proximity to each for fast carrier mobility. The dopants serve to either create vacancies or donors of
electrons within the material, thus providing the carriers to be manipulated. Variations of these materials can be found
in either an isometric (hackmanite) or asymmetric (marialite) forms providing for application in the development of
nonlinear optical devices, i.e. frequency mixers or harmonic sum or difference generation. Also discovered were results
that indicated a lack of sulphur being present, contrary to previous publications.
