Intrusive and Extrusive Igneous Rocks. Igneous rocks are called intrusive when they cool and solidify beneath the surface. Intrusive rocks form plutons and so are also called plutonic. A pluton is an igneous intrusive rock body that has cooled in the crust. When magma cools within the Earth, the cooling proceeds slowly.

Sand Media. Silica sand is the oldest and most trusted media for sand filters. All sand is different, so don't trust just any old bag of sand. Silica is definitely the way to go. If you get number 20 silica sand, that means it will filter up to 20 micron particles (much much smaller than the human eye can see).

About Silica Sand. Silica Sand contains at least 95% SiO2 and less than 0.6% iron oxide. The most common form of SiO2 is quartz, which is mined from hard rock deposits. It is chemically inert and is often white/colorless. However, the color of each sand deposit depends on the variety of minerals and rock detritus that make up the deposit.

In this process a plasma heat source is used to "burn" chemical precursors and deposit a thin glass layer on a rotating target. The target can be a tube or a solid rod, it is not necessarily round. Because of the high temperature of the plasma, this process is best suited to produce fluorine doped fused silica.

The most common form of silica sand is quartz-a chemically inert and relatively hard mineral. Silica sand grades at a 7 out of 10 on "Mohs hardness scale", making it ideal for use as filtration media and for many other applications as stated above. Silica sand can come in a wide range of shades, most of them a shade of white.

Clastic Sedimentary Rocks (Detrital) Clastic sedimentary rock (also called 'detrital' sedimentary rock) consists of sediment pieces (clasts/rock detritus) that come from weathered bedrock, cemented together to make a new rock. The clastic sediment is often referred to as "siliciclastic" because it is derived from the rocks of the crust which, …
