Identify originated and how the rocks
Identify physical properties of the rocksThe ability to distinguish between optical rocksPetrology Petrology a Almaljiuloggio branches which is the science that studies the rocks in terms of its inception and the method of their formation and knowledge of content and influencing factors. Also interested in science rocks to study how their formation and growth and stability of its field associated with the magnetic field of the Earth's magneticRock typesIgneous rocks: - It is divided into two main categories: volcanic rocks AlblutunipSedimentary rocks: - formed (Sedimentary rocks) by deposition Alklastaih substances (clastic), or organic materials, or chemical sediments (evaporites)Metamorphic rocks: - formed (Metamorphic rocks) after exposure of any type of rock (including those metamorphic rocks formed earlier) to temperature and pressure different turn from the original rock problemRocks differ from each other in terms of: -1 - mineral makeup Mineralogical classification: - each installation of a special metal rock. If it is possible to distinguish we determine the proportion of each metal in the rock.2 - Textile Texture: - a description of the rock granules in terms of: -Size sizeShape shapeThe orientation directionDistribution of metals grained distribution of mineral grains3 - structural composition: -Structure reflect the appearance of a piece of rock as a whole, and determine the relationship parts together. In dense structure be rock adjacent granules and homogeneous so that it does not appear any particular direction to حبيباته agglutination. And class structure indicate the presence of certain trends for metals agglutination. If the rock is rich Palmsamat be window structure.4 - dominant color: mostly intended color on the rockIgneous· Arise igneous rocks of the freeze molten materials from within the earth's crust at different temperatures, and freezes magma either in the ground or on the surface of the earth.· Definition magma:-Magma is a metal material in a liquid state by heat.

· Above basal with less than 45% silica. (Examplespicriteandkomatiite)· Alkaline alkalic igneous rocks with 5 - 15% alkali (K2O + Na2O) content or with a molarratio of alkali to silica greater than 1:6. (Examplesphonoliteandtrachyte)The natural properties of igneous· On فالصخور motorcycle characterized by several features specific to all other types of other rocks, and these properties are:· Show igneous rocks in the form of blocks and do not appear in the form of layers.· Very solid, useless pores, and therefore more resistant rock types of weathering processes and erosion.· Impermeable rocks does not implement water which only every difficulty, and zero-porosity in most cases, and therefore prefer sites available when the construction of dams and reservoirs.· Do not contain fossils because of the impossibility of living organisms because of the intense temperature it was before hardening.· Contain dense systems of cracks and joints that arise as a result of hardening of the and Almajma cooler contraction Bloradtha.· Colors vary from one type to another as some are light-colored and others have been characterized by dark colors, however, does not take color as standard or classification basis when the groups are similar properties.· Specific gravity ranges of igneous between 3 t 2 to 3 t 3, and there are a few of igneous rocks than qualitative weight for 3 t 3. In general it was observed that heavy rocks weight characterized colors dark, while characterized most rocks lightweight colors light, but does not apply this rule to certain types of igneous rocks such as rock glass natural features colors dark despite the lack of weight qualitative, as well as rock pumice that enters in a high percentage composition of the gases within Vjuath which works to decrease weight qualitative although I color.· Characterized by igneous rock different tissues depending on where or depth at which cooled and solidified it, characterized by plutonic rocks (ie hardened underground) sizeable particle sizes, and less grain sizes gradually closer place cooler rock and intransigence of the earth's surface.

Sedimentary rocksConsists of sedimentary rocks result was rock phenomenon on the surface of the earth to physical factors and chemical reactions by natural factors external winds and running water, etc., and as a result disintegrate rocks and then move in gestures rocky or materials dissolved even deposited in the depositional environments different then consolidated sediments dismantled depositing materials carnivorous between particle such as silica and iron oxides or by the pressure of the upper sediments.Classification of sedimentary rocks· First: Mechanical sedimentary rocks (debris).· Second: chemical sedimentary rocks.· Third: organic sedimentary rocks.· First: sedimentary rock mechanical Mechanical sedimentary rocksIt rocks formed by the deposition crumbs rock and sediment resulting from weathering and the disintegration of rocks older one, and then transmitted by water current and wind, refrigerators, and deposited in certain environments without being any chemical change, so you may dubbed sedimentary rocks detrital Detricalsedimentary rock,· Among the most prominent examples of detrital sediments, which changed to clastic rocks after particle cohesion:· Gravel Gravel changed to the reg Gravelstone stone· Sand Sand changed to Sandstone Sandstone· Mud Clay changed to Claystone mud stone
· Vary the different types of sedimentary rocks mechanical in size, depending on the different so it can be classified into the following types:· Alkoonjlomirat Conglomerates:· A sedimentary rock mechanical consisting of Slater spherical diameter of 2 mm, and be edges Foreign circular or Mbria edges due to transfer distances by water currents such as rivers, and granules Alkoonjlomirat consist of quartz, the different shapes and sizes, coalesce by calcium carbonate or silica , or iron oxides, and consists Alkoonjlomirat in valleys, streams and rivers.· Alabaster Breccia:· A rock composed of Slater is Mbria edges, any show sharp edges, which indicates that it did not transfer over long distances by water currents river, any deposited in the place I grew up in, or close to it, and there are usually near springs or rivers at the foothills of the mountains , or on the sides of hills. Particle size:> 2 mm· Sandstone Sandstone:· A sedimentary rock mechanical composed of clastic mineral granules, consisting of metals, quartz, feldspar, mica, fuse together by lime (calcium carbonate) or silica, or iron oxides, and particle size ranges between 1/16 - 2 mm.· Stone clay Claystone:· Consist of deposits soft minutes no more than a diameter of 0.05 mm, deposition rivers in deep water or accumulate on the bottoms freshwater lakes, has been consolidating particle after due to dry and lose all their attendant water, and returns the drying process to pressure which is located on the sediment due accumulation of layers of sediment newer above, there may be pure mud-rock free from impurities such as kaolin. If you entered into a mud-rock formation some lime compounds learn then Balmarl to or clay limestone marl, containing a high percentage of the mineral calcium carbonate. If mixed clay with sand comprise what is known as the child Loam, and mud-rock of the so-called mud shale, which is a thin sheets stacked on top of each other,
Second: chemical sedimentary rocks Chemical sedimentary rocks:Forming this type of rock as a result of deposition crystals to mineral material was dissolved in aqueous solutions saturated, then evaporated, including the amount of water to reach after that to a degree above saturation, Vtaatersb a result dissolved minerals which on the surface of the earth, and called for this type of rock name rocks evaporite Evaporites. May consist of sedimentary rocks chemical in some cases as a result of chemical reactions between minerals contained in water in nature, composed as a result new minerals are deposited on the bottoms of water basins made up sediments, and the most important sedimentary rocks chemical origination rock salt halite, gypsum Gypsum, Altova Tufa, Travertine Travertine, Dolomite Dolomite and some types of inorganic limestone.
Third: organic sedimentary rocks Organic sedimentary rocks:Consists of this type of sedimentary rocks of the remains of living organisms, whether animal or vegetable, and sometimes called sedimentary rocks biochemical Biochemical sedimentary rocks, the most important examples limestone reefs Reefallimestone consisting of cohesion remains coral reefs dead saturated calcium carbonate extracted from sea water, and contribute to these metals in the cohesion of residues reefs, stone chalk Chalk which consists of cohesion remains of microscopic animal and vegetable, and stone coal Coal, which consists of decomposing plants after burying roasted and exposed to the impact of global temperature and pressure (Mohammed Ghani Musharraf, 2002).
