Picture below (Figure 1): Properties of soil ternary phase diagram (CHEMIX School screen shot)
Axis consisting of three sedimentary elements : A = clay , B= sand and C= silt .
Example from property of soils ternary phase diagram: (20% Clay , 40% Sand , 40% Silt ) = Loam
Sand : A sedimentary material with grains between
0.06 and 2.0 millimeters in diameter.
Silt : A sedimentary material consisting of very fine
particles between 0.002 - 0.06 millimeters in diameter.
Clay : A sedimentary material with grains smaller than 0.002
millimeters in diameter
Loam: Soil composed of a mixture of sand, clay, silt, and organic
matter
