A TECHNIQUE FOR THE RAPID DETERMINATION OF THE LIGHT MINERALS OF DETRITAL SANDS

DETERMINATION OF LIGHT MINERALS OF DETRITAL SANDS BY ETCHING AND STAINING PROCEDURES IS GREATLY FACILITATED WITH THE USE OF A BLACK ROOFING TAR MOUNTING MEDIUM. THIS MEDIUM IS UNAFFECTED BY HYDROFLUORIC ACID ETCHING AND PROVIDES A CONVENIENT DARK BACKGROUND FOR COUNTING STAINED GRAINS WITH REFLECTED LIGHT. THE TECHNIQUE IS PARTICULARLY SUITED FOR THE DETERMINATION OF QUARTZ, CHERT, AND FELDSPAR PERCENTAGES OF LARGE NUMBERS OF SAMPLES. /AUTHOR/
