Typical grain size analysis data sheet. Slide 1 most sediments contain particles that have a range of sizes, so the mean or average grain size is used in description. Features 6 color chips, 4 grain sizes & tables for classifying particle size.

Moreover, a typical grain size distribution curve of a medium sand is shown in figure 2. Use these grain size cards in your observations of sedimentary rocks. You can use them for hand specimens at home or in the classroom, or on rock outcrops outdoors.

The sand grain size chart is one of the products that shows the size, shape, color, and density. The chart is used for describing soil samples and initial site evaluations, and is classified according to the wentworth scale. You have no items in your shopping cart.

Based on the grain size of the particle, sand is classified as fine sand (0.075 to 0.425mm), medium sand (0.425 to. The gauge covers grain size, colors, soil classification systems, a ruler, and even more ways to identify soil and rock in the field. Followings are the classification of sand:

A typical grain size analysis data sheet is presented below (table 3). Consists of sphericity/roundness measuring chart; These charts are normally centered on the arenitic grain sizes, since sand grains are difficult to measure, whereas for gravels we can use rulers or measuring tapes.
