Labradorite which is a crystalline feldspar of the triclinic class is well known for the striking iridescence or play of colours which it exhibits. The phenomenon is displayed not only by specimens from the locality which gave its name to the substance, namely the coast of Labrador, but also by those from other parts of the world. This fact and the highly distinctive character of the effects observed suggest that they are in some way connected with the nature of the feldspar itself. Hintze…

Intimate Feldspar Intergrowths
Intimate intergrowths of two or more feldspars have great genetic significance. They may have formed by more than one process, so that the microstructures may record several stages of formation. Some
Rendering the effect of labradoescence
This work provides a reflectance model for labradorescence that is directly derived from the physical characteristics of such materials, which can be used for predictive rendering purposes, but also for generic rendering applications.
A Review of Microcolorimetry for Textile, Food, Dental and Optoelectronic Industries
A microscope spectrophotometer may be used for colorimetry with transmitted, reflected or emitted light. Optical fibers may be used to link the microscope to remote samples, which may be commercial
Real-time rocks: shader-based labradorite
Mining ideas for learning graphics, representing something visually complex such as labradorite can be unearthed as a gem of an assignment, and one can learn a fragment of shading while procedurally chipping away at the assignment.


Studies of iridescent colour, and the structure producing it. III.—The colours of labrador felspar
The brilliant colours displayed by reflexion at certain angles from a polished surface of labradorite, or Labrador felspar, have long been known, and specimens of the material are to be seen in most

The structures of some typical members of the felspar group were determined by Taylor, Darbyshire and Strunz (1934), and an attempt was made to explain the characteristic twinnings and the nature of

From X-ray oscillation and rotation photographs of a limited number of plagioclase felspars it seems probable that the structure type depends upon the chemical composition in the following way. From
The nature and properties of aluminosilicate framework structures
In recent years it has been shown by X-ray methods that the structures of a large number of crystals are based on frameworks of linked tetrahedral groups of oxygen atoms. The individual tetrahedra
