FILTRATION SAND
Typically sand is clean, immature sand, dominated by fresh transparent to translucent very light feldspar, but also containing dark pyroxene and other components.
Microscopic examination reveals subhedral and angular broken crystals of fresh plagioclase, fresh to slightly iron-stained pyroxene, fresh opaque oxides, unstrained quartz, fresh green hornblende and fresh to lightly iron-stained brown biotite. There are also cuspate shards of colourless isotropic fresh glass. Less commonly the same type of glass occurs as equant massive fragments or as porous pumiceous fragments. Minor other components comprise small lithic clasts of fresh to lightly weathered finely crystalline intermediate and acid volcanic rock.
The sand is typically regarded as clean, texturally and mineralogically immature sand, dominated by Piagiociase feldspar but also carrying other crystals, volcanic rock fragments and siliceous glass shards. Go back
Filter / Pool sand is available in 25kg bags or metric tonne bulk bags (by arragement).
