Wentworth grain size chart from United States Geological Survey Open-File Report 2006-1195: Note size typos; 33.1mm is 38.1 & .545mm is .594 Beach cobbles at Nash Point, South Wales. Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.
In geology, a boulder (or rarely bowlder) [1] is a rock fragment with size greater than 25.6 cm (10.1 in) in diameter. [2] Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. [3] In common usage, a boulder is too large for a person to move.
Weight is disputed; a 2006 analysis estimated the depth of this stone at only 1.8–2.5 m, for a weight of 250–300 t. [32] Weight formerly said to be 550 to 600 t. [34] [35] 230 t [36] Mausoleum of Theodoric: Roof slab Ravenna, Italy: Ostrogothic Kingdom: 220 t [37] Menkaure's Pyramid: Giza, Egypt: Largest stones in mortuary temple 200 t [38 ...
Therefore, a correlation between the iceberg size and the boulder size can be established. For example, a 1.5-metre-diameter (5 ft) boulder can be carried by a 3-metre-high (10 ft) iceberg and could be found stranded at higher elevations than a 2-metre (7 ft) boulder, which requires a 4-metre-high (13 ft) iceberg. [9]
The boulder is a huge granite rock measuring 83 feet (25 m) in length, 23 feet (7.0 m) in height above the ground, and 37 feet (11 m) in width. It weighs upwards of 5,000 short tons (4,500,000 kg). It weighs upwards of 5,000 short tons (4,500,000 kg).

The Zayit Stone is a 38-pound (17 kg) limestone boulder dating to the 10th century BCE, discovered on 15 July 2005 at Tel Zayit (Zeitah) in the Guvrin Valley, about 50 kilometres (31 mi) southwest of Jerusalem. [1] The boulder measures 37.5 by 27 by 15.7 centimetres (14.8 in × 10.6 in × 6.2 in) and was embedded in the stone wall of a building.
