MINERALOGICAL ANALYSIS OF SOILS

ANALYSE MINERALOGIQUE DES SOLS

THE EXAMINATION OF THIN FILMS WITH A POLARIZING MICROSCOPE AND THE USE OF A POINT COUNTER FOR IDENTIFYING FELDSPARS GIVE A SEMI-QUANTITATIVE APPROXIMATION INSUFFICIENT TO CARRY OUT A COMPLETE MINERALOGICAL ANALYSIS OF GRANITE OR SAND. IT IS PROPOSED TO USE X-RAY DIFFRACTION ON THE MOST COMMONLY ENCOUNTERED FELDSPARS. IN 1976, CALIBRATION CURVES WILL BE DRAWN FOR ORTHOSE, ALBITE AND OLIGOCLASE. THE METHOD WILL ALSO BE APPLIED TO THE DETERMINATION OF THE PROPORTION OF FELDSPAR IN GRANITE AND SAND.
