A METHOD FOR THE PLANAR ILLUSTRATION OF CRYSTAL FORMS

摘要:

Abstract:

The drafting of the stereogram to present precisely a crystal form was accompanied with the use of a duoble ring reflection goniometer. The stereographic presentation methods of mineral crystals, however, have not been adopted widely by the heavy mineral researchers yet even over a hundred years later which caused some incorrect illustrations of Crystal forms and crystallograp ic indices in the publications. In addition to the stereographic methods illustrating crystal forms, the methods for the planar illu...
