lapilli

lapilli
Noun

This term is used primarily in volcanology and geology to describe a specific size class of tephra. It is distinguished from volcanic ash, which is smaller than 2 millimeters, and volcanic bombs, which are larger than 64 millimeters. The term carries a technical, scientific register and is rarely used in casual conversation unless describing a geological site.

Grammatically, lapilli is the plural form of the Latin word lapillus. In English scientific writing, it is treated as a plural noun. While some writers may attempt to use it as a collective mass noun, it traditionally refers to the individual fragments of rock.
