Pebblesized

Pebblesized is an informal, descriptive term used to describe material composed of or transitioning into pebble-sized particles. It is often written as pebble-sized, but some texts use pebblesized as a single word.

Size range: Pebble size is commonly defined in geology as roughly 4 to 64 millimeters in diameter; therefore pebblesized material typically refers to particles within that range. Some sources may broaden the lower or upper bounds.

Contexts: In geology and sedimentology, pebblesized material occurs in river gravels, alluvial deposits, beaches, and in some sedimentary rocks. In construction and landscaping, pebblesized aggregates are used for concrete, drainage layers, or decorative features.

Measurement and terminology: Particle size distribution for pebblesized material is usually determined by sieve analysis for the coarser fractions, with additional methods such as image analysis, hydrometer, or laser diffraction for finer fractions. Because the term is informal, it is important to specify the exact size range when precision is required.
