Transmission Electron Microscope Investigations of the Microstructures of Microclines

  • Chapter

Part of the book series: NATO ASI Series ((ASIC,volume 137))

Abstract

(001) thin sections of microcline almost invariably exhibit a cross-hatched microstructure when examined between crossedpolarizers in the optical microscope. Since 1972, transmission electron microscopy (TEM) and electron diffraction have been used to study the microstructures in specimens of microcline from a wide range of geological conditions. It is the purpose of this paper to review these studies and to discuss them in the light of previous ideas regarding the nature and origin of the cross-hatching which have been developed from optical microscope and X-ray diffraction observations.
