The history of soil classification and description has been described by Child 1986. Early attempts to divide soil into different categories used laboratory testing, typically particle size distribution. Casagrande 1947 considered that much of this textural soil classification was unreliable, because it

Nature rarely has sharp boundaries and the classification and naming of rocks often impose what appears to be sharp boundary names onto a continuous spectrum.size categories Table B.3, and in that case, the ternary classification system shown in Fig. B.2 is prescribed. Because pyroclastic rocks are composed of various proportions of vitric, crystal, and lithic constituents of juvenile, cognate, or accidental origin, the classification should also be made according to the proportion of these constituents in a sample, as is illustrated in Fig. B.3.

Simplified Rock Classification This table gives you an idea of how various rocks are classified.1 Size The important size classifications are boulders, cobbles, gravel, sand, silt, and clay. Numerous grade scales have been developed to establish the limits of size for each of these classifications. Table 31 shows some of the commonly used grade scales for compari-son. Note that the range in size for a particular class

Rock Classification Appalachian State University

Rock Classification Appalachian State University CLASSIFICATION The classification of rocks is based on two criteria, TEXTURE and COMPOSITION. The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. Such factors are controlled by the process which formed the rock.CLASSIFICATION The classification of rocks is based on two criteria, TEXTURE and COMPOSITION. The texture has to do with the sizes and shapes of mineral grains and other constituents in a rock, and how these sizes and shapes relate to each other. Such factors are controlled by the process which formed the rock.Mineral size, or grain size in sedimentary rocks, is a noticeable textural feature. The classification in Table 1 is been based on visual identification using a hand lens. For metamorphic and igneous rocks the same reasoning is applicable, with a grain size qualification only being necessary in the coarser grained rocks.
