IGNEOUS ROCKS 1. Igneous rocks have crystallized from solidified magma. Igneous rocks can be classified in a number of ways and one of them is based on mode of occurrence. They occur either as intrusive (below the surface) bodies or as extrusive masses solidified at the Earth’s surface. The terms “intrusive” and “extrusive” refer to the place where rocks solidified.
11
2. The grain size of igneous rocks depends on their occurrence. The intrusive rocks generally cool more slowly than the extrusive rocks and crystallize to a larger grain size. The coarser-grained intrusive rocks with grain size of more than 0.5 mm called plutonic or abyssal are referred to as intrusive igneous rocks because they are intruded into older pre-existing rocks. Extrusive or volcanic rocks have even finer grains, less than 0.05 mm and are glassy. 3. Exposed igneous rocks are most numerous in mountain zones for two reasons. First, the mountain belts have been zones of major deformation. Second, uplifts in mountain belts have permitted plutonic masses to be formed. 4. The largest bodies of igneous rocks are called batholiths. Batholiths cooled very slowly. This slow cooling permitted large mineral grains to form. It is not surprising that batholiths are composed mainly of granitic rocks with large crystals called plutons. As is known, granites and diorites belong to the group of intrusive or plutonic rocks formed by solidification of igneous mass under the Earth’s crust. Granites sometimes form smaller masses called stocks, when the occurrence has an irregular shape but smaller dimensions than the batholiths. 5. Laccoliths and sills, which are very similar, are intruded between sedimentary rocks. Sills are thin and they may be horizontal, inclined or vertical. Laccoliths are thicker bodies and in some cases they form mountains. 6. Dykes are also intrusive bodies. They range in thickness from a few inches to several thousand feet. Dykes are generally much longer than they are wide. Most dykes occupy cracks and have straight parallel walls. These bodies cool much more rapidly and are commonly fine-grained. For example, granite may occur in dykes that cut older rocks. 7. Pegmatites (quartz, orthoclase and mica) also belong to the group of plutonic or intrusive rocks. They occur in numerous veins which usually cut through other plutonites, most often granite, or adjacent rocks. 8. Extrusive igneous rocks have been formed from lava flows which come from fissures to the surface and form fields of volcanic rocks such as rhyolite, andesite, basalt, as well as volcanic ashes and dust, tuff, etc. As a rule, these rocks of volcanic
12
origin cool rapidly and are fine-grained. It is interesting to note that basalt is the most abundant of all lava types. It is the principal rock type of the ocean floor. 9. Igneous rocks are rich in minerals that are important economically or have great scientific value. Igneous rocks and their veins are rich in iron, gold, zinc, nickel and other ferrous metals.
1. Igneous rocks have been formed by sedimentation. 2. Intrusive rocks have been formed by the cooling of rocks of the Earth’s crust. 3. Extrusive rocks have been formed in the same way. 4. The grain size of igneous rocks depends on mode of occurrence. 5. Exposed igneous rocks are numerous in mountain zones. 6. Granites and diorites belong to the group of extrusive rocks. 7. As a rule, granite may occur in dykes. 8. Pegmatites do not belong to the group of plutonic or intrusive rocks ЗАД АН И Е № 14 П е ре пиш ите в опросы и письме нноотв е тьте наних . 1.

SEDIMENTARY ROCKS 1.The rocks of the Earth’s crust are divided into three main groups: sedimentary rocks, which consist of fragments or particles of pre-existing rocks; igneous rocks which have solidified from magma and metamorphic rocks. Metamorphic rocks have been derived from either igneous or sedimentary rocks. 2. Sedimentary rocks represent one of the three major groups of rocks that make up the crust of the Earth. Most sedimentary rocks have originated by sedimentation. They are layered or stratified. Thus, stratification is the most important characteristic of sediments and sedimentary rocks. It is necessary to note that the processes which lead to the formation of sedimentary rocks are going on around us. 3. Sediments are formed at or very near the surface of the Earth by the action of heat, water (rivers, glaciers, seas and lakes) and organisms. It should be noted that 95 per cent of the Earth’s crust is made up of igneous rocks and that only 5 per cent is sedimentary. In contrast, the amount of sedimentary rocks on the Earth’s surface is three times that of igneous rocks. 4. Strictly speaking, sedimentary rocks form a very small proportion by volume of the rocks of the Earth’s crust. On the contrary, about three quarters of the Earth’s surface
14
is occupied by sedimentary rocks. It means that most of sedimentary rocks are formed by sediments, accumulations of solid material on the Earth’s surface. 5. The thickness of the layers of sedimentary rocks can vary greatly from place to place. They can be formed by the mechanical action of water, wind, frost and organic decay. Such sediments as gravel, sand and clay can be transformed into conglomerates, sandstones and clay schists as a result of the accumulation of materials achieved by the destructive mechanical action of water and wind. 6. Mechanical sediments can by unconsolidated and consolidated. For example, gravel, sand and clay form the group of unconsolidated mechanical sediments, because they consist of loose uncemented particles (grains). 7. On the Earth’s surface we also find consolidated rocks, which are very similar to the loose sediments whose particles are firmly cemented to one another by some substance. The usual cementing substances are sand, clay, calcium carbonate and others. Thus sandstones are consolidated rocks composed of round or angular sand grains, more or less consolidated. Like sand, sandstones can be divided into finegrained, medium-grained and coarse-grained. 8. On the other hand, chemical sediments are the result of deposits of accumulations of substances achieved by the destructive chemical action of water. The minerals such as rock salt, gypsum and others are formed through sedimentation of mineral substances that are dissolved in water. 9. Sediments can also be formed by the decay of the remains of organisms, by the accumulation of plant relics. They are called organic sediments. Limestones, peat, coal, mineral oil and other sediments may serve as an example of organic sediments. 10. The most principal kinds of sedimentary rocks are conglomerate, sandstone, siltstone, shale, limestone and dolomite. Many other kinds with large practical value include common salt, gypsum, phosphate, iron oxide and coal. 11. As is known, water, wind and organisms are called external forces, because their action depends on the energy which our planet receives from the Sun.
1. The rocks of the Earth’s crust are divided into two main groups.
15
2. Igneous rocks are composed of particles of pre-existing rocks. 3. Sedimentary rocks are stratified. 4. Sediments are formed by the action of glaciers. 5. Igneous rocks make up 75 per cent of exposed rocks. 6. Conglomerates are formed as a result of the accumulation of materials caused by the destructive mechanical action of water. 7. Sandstones are consolidated rocks. 8. Clays are unconsolidated mechanical sediments. 9. Chemical sediments are formed by the destructive chemical action of water. 10. Peat and coal are organic sediments which are of great practical value. 11. Clay schist was formed at the beginning of the sedimentation period and clay was formed later.

METAMORPHIC ROCKS 1. The problem discussed concerns metamorphic rocks which compose the third large family of rocks. “Metamorphic” means “changed from”. It shows that the original rock has been changed from its primary form to a new one. Being subjected to pressure, heat and chemically active fluids beneath the Earth’s surface, various rocks in the Earth’s crust undergo changes in texture, in mineral composition and structure and are transformed into metamorphic rocks. The process described is called metamorphism.

2. As is known, metamorphic rocks have been developed from earlier igneous and sedimentary rocks by the action of heat and pressure. 3. Gneisses, mica schists, phyllites, marbles, slate, quartz, etc. belong to the same group of rocks. Having the same mineral composition as granite, gneisses consist chiefly of quartz, orthoclase and mica. However unlike granite, they have a schistose structure. It means that their constituents are disturbed in bands or layers and run parallel to each other in one direction. If disturbed the rock cleaves easily into separate plates. 4. The role of water in metamorphism is determined by at least four variable geologically related parameters: rock pressure, temperature, water pressure, and the amount of water present. 5. During a normal progressive metamorphism rock pressure and temperature are interdependent, and the amount of water and the pressure of water are related to the sediments and to the degree of metamorphism in such a way that, generally speaking, the low-grade metamorphic rocks are characterized by the excess of water. The medium-grade rocks defined by some deficiency of water and the high-grade metamorphic rocks are characterized by the absence of water. 6. Many of the metamorphic rocks mentioned above consist of flaky materials such as mica and chlorite. These minerals cause the rock to split into thin sheets, and rocks become foliated. 7. Slate, phyllite, schist and gneiss belong to the group of foliated metamorphic rocks. Marble and quartzite are non-foliated metamorphic rocks. 8. The structure of metamorphic rocks is of importance because it shows the nature of pre-existing rocks and the mechanism of metamorphic deformation. Every trace of original structure is of great importance to geologists. It gives an opportunity of analysing the causes of its metamorphism. 9.Being often called crystalline schists, metamorphic rocks such as gneisses and mica have a schistose structure. Metamorphic rocks represent the oldest portion of the Earth’s crust. They are mostly found in the regions of mountain belts where great dislocations on the Earth once took place.

PROSPECTING 1. Mining activities include prospecting and exploration for a mineral deposit through finding, proving, developing, extracting and processing the ore. That is why it is possible to divide the mining activity into three major phases: 1) before mining which involves prospecting and exploration required to locate, characterize and prove a potential ore body; 2) mining which refers to actual coal or ore extraction. Extraction processes include underground or surface mining and dredging; 3) after mining which involves processing and preparing the raw ore for the end product. 2. As has already been said, before a mineral deposit can be worked, that is, before it can be extracted form the Earth for use by man, it must first be found. The search for economically useful mineral deposits is called prospecting. To establish the quality and quantity of a mineral deposit, the type of country rock, etc. means to prove it and this process is called proving. Prospecting and proving are only two different stages of mining geological exploration, the latter included drilling and driving of openings. 3. Last century prospectors looked for visible evidence of mineralization on the surface of the Earth. To recognize valuable minerals it was necessary to know their various distinctive physical properties. For example, gold occurs in nature as a heavy malleable yellow metal. Galena, the most important mineral containing lead, is dark grey, heavy and lustrous. The first ores of iron to be mined were deposits of magnetite, a black heavy mineral capable of attracting a piece of iron. 4. As the deposits of mineral that cropped out at the surface were mined, the search for additional supplies of minerals took place. The science of geology was used to explain the occurrence of ore deposits.

5. The aim of geological prospecting is to provide information on a preliminary estimation of the deposit and the costs of the geological investigations to be made. It also indicates whether it is available to continue the exploration or not. Prospecting work includes three stages: a) finding signs of the mineral; b) finding the deposit; c) exploring the deposit. 6. General indication of the possibility of exposing this or that mineral in a locality can be obtained by studying its general topographical relief, the type of ground and its general natural conditions. Thus, in mountainous regions where fissures were formed during the process of mountain formation, ore minerals could be expected in the fissure fillings. In hilly regions, sedimentary deposits would be expected. 7. Certain deposits are found only in a particular type of ground. Coal seams, for example, are found in sedimentary formations mainly consisting of sandstones and shales. Veins, on the other hand, are found in crystalline (igneous) rocks, and the type of country rock usually determines the type of minerals. 8. At present, prospecting methods to be used are as follows: 1. Surface geological and mineralogical prospecting such as panning. 2. Geophysical, geochemical, geobotanical prospecting. 3. Aerial photography with geological interpretation of the data to be obtained is highly effective from aircraft or helicopter. Besides, successful development of space research has made it possible to explore the Earth’s resources from space satellites. 9.In modern prospecting the methods mentioned above are used together with the study of geological maps. The search for economically useful mineral deposits is called proving.
