Granule (geology)

A granule is a clast of rock with a particle size of 2 to 4 millimetres based on the Krumbein phi scale of sedimentology. Granules are generally considered to be larger than sand (0.0625 to 2 millimetres diameter) and smaller than pebbles (4 to 64 millimetres diameter). A rock made predominantly of granules is termed a granule conglomerate.[1]

Granule (cell biology), any of several submicroscopic structures, some with explicable origins, others noted only as cell type-specific features of unknown function

Azurophil granule, a structure characteristic of the azurophil eukarytotic cell type

Chromaffin granule, a structure characteristic of the chromophil eukaryotic cell type

Martian spherules, spherical granules of material found on the surface of the planet Mars

Granule (geology), a specified particle size of 2–4 millimetres (-1 to -2 on the φ scale)

Granule, in pharmaceutical terms, small particles gathered into a larger, permanent aggregate in which the original particles can still be identified
