| Abstract: | A systematical measurement has been made to the feldspar phenocrysts in granodiorite massif from Fangshan, Beijing. The average number of measurements-4.37 per km2. The elements of the measurement are the length and linear content of feldspar phenocrysts. The data processing on distribution statistics, the best division of ordering samples and the variation of trend have been conducted, which have revealed the distribution rule and mathematical characteristics of feldspar phenocrysts. Based on these analyses, a reasonable principle of defining lithofacies zones is proposed, and the trend-lithofacies zones are delineated. |
