A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of 64–256 millimeters (2.5–10.1 in), larger than a pebble and smaller than a boulder.Other scales define a cobble's size in slightly different terms. A rock made predominantly of cobbles is termed a conglomerate. Cobblestone is a building material based on cobbles.

What is the difference between a pebble and a cobble?

Blocks are angular to subangular clasts > 64 millimeters (mm); bombs are rounded to subrounded clasts > 64 mm. Determine percent of each size present (ash, lapilli, blocks, and bombs) and list in decreasing order after rock name. Preceed rock name with the term "welded" for pyroclastic rocks which retained enough heat to fuse after deposition.

Sieve mesh sizes are based on dimensions of the mesh size opening, or on the number of openings per linear inch. The two major standards governing test sieves and appropriate sizes are ASTM E11 and ISO 565/3310-1, both of which specify parameters for aperture dimensions, mesh size, and statistical variations. Opening sizes and mesh diameters for test sieves are often duplicated between these ...

A cobble is a clast of rock with a particle size of ~2.5 to 10 inches or 6-25 cm, based on the Krumbein phi scale of sedimentology. Cobbles are generally considered to be larger than pebbles (4 to 64 millimetres diameter) and smaller than boulders (greater than 256 millimetres diameter, or generally, 30 cm/1 foot [1 meter is 3 feet]).

Cobble (geology)

The grain size distribution of a sediment sample is determined by any one of a number of techniques or combination of techniques depending on the range of sizes present in a sample. For this procedure, "fines" are any particle smaller than 63.5 microns. Sand is 63.5 microns to 2 mm in diameter. Gravel is larger than 2 mm.
