Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, …

On the Chemical Identification and Classification of Minerals

To univocally identify mineral species on the basis of their formula, the IMA-CNMNC recommends the use of the dominant-valency rule and/or the site-total-charge approach, which can be considered two procedures complementary to each other for mineral identification. In this regard, several worked examples are provided in this study …
