The whole thing has become terribly opaque and dishonest and it's a way of hiding obligations. PFI has now largely broken down and we are in the ludicrous situation where the government is having to provide the funds for the private finance initiative.
It is formed in the way that all minerals generally are. formedâthrough crystallization, the process by which atoms are. arranged to form a material with a crystal structure. One of the two ways minerals form is by: 1. crystallization of magma (cools inside the crust) or lava (cools. & hardens on the surface) 2. crystallization of materials dissolved in water. When these liquids cool to a solid state, they form crystals.
Minerals can be formed from the intense heat and pressure found far beneath the earth's crust in the mantle, where molten rock flows as liquid magma. Silicates in the magma can form minerals such as hornblende and other igneous rocks as the magma cools. This process can take millions of years.Ninety-five percent of the earth's crust is formed from nine minerals, all of which are silicates, formed in this manner.inerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
