Abstract: | Granulometric analysis of rudites on outcrop-photographs As it is impossible to determine the grain-size distribution of well-consolidated rudites by sieving, it has been attempted to use outcrop-photographs for their granulometric analysis. In order to assess the accuracy of this photo-method, nineteen samples of poorly consolidated rudites were subjected to analysis by both methods. It resulted that the two sets of data obtained could be correlated rather well, using a relatively simple formula. Although some broader experimental work would still seem advisable, it became quite clear that the photo-method is simpler as well as more accurate than the sieving method. It is therefore suggested to develop it as the standard method for granulometric studies of all rudites. |
