Particle Size Distribution Curve
D60 sized particle can be of any size and 60 percent of the soil is made up of particles of size smaller than that D60 sized particle. In other words 60 percent of the soil mass has particles which all have size less than this D60 size.

Pebble vs. Gravel
Pebble. A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules (2–4 mm (0.079–0.157 in) in diameter) and smaller than cobbles (64–256 mm (2.5–10.1 in) in diameter).

What Are the Different Gravel Sizes? (with pictures)
Gravel is often made from crushed rock. There are a number of other mid-range sizes available in many places, too, most of which are designed with specific projects or uses in mind. Size #3, for instance, is usually 1.5 to 2 inches (about 3.8 to 5 cm) in diameter, and is often best for residential draining projects; #8, which is usually 3/8 to 1/2 an inch (1 to 1.2 cm)

Gravel sand refers to a sand which content of gravel grain in sand stone that account for 25% to – 50% in total quality (particle size > 2 mm). The standard of sand used in architecture: refers to rock fragments that its particle sizes < 5 mm , form and accumulate in natural waters such as lakes, seas, and rivers.

Grain size
Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks. The term may also be applied to other granular materials . This is different from the crystallite size, which refers to the size of a single crystal inside a particle or grain.

Image Analysis Techniques on Evaluation of Particle Size Distribution
Particle size distribution of granular materials is usually evaluated by sieve analysis test. In this research, an image analysis technique using ImageJ is proposed to evaluate particle size distribution of gravels. On particular conditions, some differences of gradation curves determined by sieve analysis and image analysis were observed.

Sedimentary Rocks
Mudrocks are made of fine grained clasts (silt and clay sized) . A siltstone is one variety that consists of silt-sized fragments. A shale is composed of clay sized particles and is a rock that tends to break into thin flat fragments (See figure 7.6e in your text). A mudstone is similar to a shale, but does not break into thin flat fragments.
