VOLCANIC LAPILLO, VOLCANIC LAVA 10/16 mm (c.ca 29 Kg - 33 lt).

Pumice and lapilli are the product of explosive volcanic eruptions formed following a violent expansion of the gases dissolved in lavas of acidic chemical composition: the rapid cooling of the rock prevented its crystallization, trapping the gases inside and generating minerals alveolar expanded more or less accentuated.

In fact, during the solidification phase, the vapors present in the magma, suddenly released, caused the swelling of the entire mass of the magma and during this rapid cooling phase the differences in the physical structure of the various volcanic aggregates were determined: the volcanic lapillus formed from a magma with lower silica content.

The lower viscosity and the slower cooling of the lava facilitated the escape of a certain quantity of the gases present in the magma.

Minerals were formed characterized by vacuums with an average diameter greater than those of the pumice but with a much smaller number.
