PUMICE  -  Scoria  - Basaltic Pumice 

Description: Basaltic Pumice 

Basic pumice is called as Scoria in literature, it is a kind of pumice that the specific gravity is around **2gr/cm3 and it is mined out in the nature brown, black, reddish colors. The old name for scoria is cinder or volcanic cinder. When it is used for landscaping it is mostly called as lava rock.

Basaltic pumice or with the other name lava rock is a highly vesicular volcanic rock that basaltic or andesitic in composition. Basaltic pumice is low in mass as a result of its numerous holes or vesicles, but consider to pumice, all scoria has a specific gravity greater than 1, and because of that sinks in water. 

Basalt is the most basic rock of Gabro subgroup and one of the black color, homogenius, highy density and heavy volcanic rocks. The reserves are mostly massive, core and effluence  
Its mostly used as paving, construction rock, bridge construction rock, railway ballast material, stabilisation and protection of offshore pipelines, cables and other kind installations.
