His seeds are fragments of calcium chloride, and his soil is a solution of the alkaline carbonates, phosphates, or silicates.
silicates, carbonates, sulphides, and sulphates are the most abundant salts.
In limestone much of the mass may be replaced by garnet and other silicates in a matrix of quartz.
They are silicates of lime and magnesia usually with aluminum and iron.
Agalite and talc, which are silicates of magnesia, are also used.
This well-known substance is essentially a mixture of silicates with an excess of silica or silicic acid.
It may be pure quartz; but oftener it is mixed with silicates from the rock containing the mineral.
This is especially true of the limestone, which may be changed completely to solid masses of quartz and silicates.
Should borates or silicates be present it is possible to express in terms of these.
The sands and sandstones become highly crystalline quartzites, spotted with porphyritic developments of silicates.
silicate sil·i·cate (sĭl'ĭ-kāt', -kĭt)
Any of numerous compounds containing silicon, oxygen, and one or more metals; a salt of silicic acid.
The main minerals found in many rocks. Silicates are composed of atoms of silicon, oxygen, and elements such as potassium, sodium, or calcium, under great heat and pressure. Silicates make up about one-quarter of the crust of the Earth.
Note: Mica and quartz are silicates.
