SOME INTERDICIPLINARY ASPECTS OF MINERALOGY
This paper gives a brief discussion of three problems related to the inter disciplinary aspects of mineralogy: (1) The relationship between the external forms and internal microscopic structures of crystals is traced historically, with special emphasis on calaverite whose indexing difficulty leads to incommensurately modulated structure, a kind of quasiperiodic structure. (2) The real structure (including imperfections and heterogeneous phase) of mineral crystals has been found to be a fertile field and of immense potential for mineralogy. (3) The study of internal periodic structure of opals in the scale of microns gave a first instance of mesoscopic periodic structure, and influenced materials science of the fabrication of photonic crystals and nanostrctures.
