| Projections are defined according to their size: higher than 64 mm for the blocks, of 2mm to 64 mm for the lapilli, and less than 2 mm for ashes. |
| Mount Vesuvius' eruption buried the ancient Roman city of Pompeii in volcanic ash and lapilli, preserving it in its current ghost-town-like state. |
| Some matrix ash samples were also analysed to ensure that the complete geochemical range could be assessed, and where lapilli were not available. |
| We infer that the framework through which transport took place consists of lapilli lodged within elutriation networks similar to those observed in the field. |
| The Longcroft Tuffs, a poorly exposed succession at least 140 m thick, are dominated by lapilli tuffs of andesitic composition. |
| The solid matter thrown out by volcanoes consists of lapilli, scoriae, dust and bombs. |
