I. Прочитайте та усно перекладіть текст Minerals

1. Minerals that make up rocks are defined as inorganic sub­stances which occur naturally and have a definite chemical composi­tion and physical properties which vary within known limits.

2. The major properties are colour, crystal form, hardness, cleavage and others. Cleavage is one of the most diagnostically useful mineralogical properties which can be found throughout the mineral.

3. Minerals of use to man can be grouped into two broad catego­ries: 1) metals, such as aluminium, copper, gold, silver, iron, tin, platinum, chromium, nickel, lead and zinc, and 2) non-me­tallic minerals, such as diamonds, salt, limestone, cement, sul­phur, and asbestos. When minerals occur so that they can be worked at a profit they are called ore deposits. Mineral deposits are seldom equally rich throughout. Economic minerals are those which are of economic impor­tance and include both metallic and non-metallic minerals.

4. Most minerals consist of several elements. Such elements are oxygen, silicon, titanium, aluminium, iron, magnesium, calcium, sodium, potassium and hydrogen. They make up more than 99 per cent by weight of all the rock-forming minerals. Of these, alu­minium, iron and magnesium are industrial metals. The other metals are present in small quantities, mostly in igneous rocks.

5. For example, iron is one of the most abundant metals in the Earth's crust. There are three important classes of iron deposits: deposits associated with igneous rocks; residual deposits and sedi­mentary deposits. Iron deposits associated with igneous rocks are usually small but very rich bodies.

6. Residual deposits of iron minerals are formed wherever weather­ing occurs. Iron deposits formed this way are very widespread. It should be stressed that the residual deposits were among the first to be exploited by man.

7. As the essential component of every variety of steel, iron is the most important of all industrial metals. It has played a large part in the development of our modern civilization. Iron ores are mainly used for producing cast iron, steels and ferro-alloys. Iron fields are worked by surface mining which is more eco­nomical.
