Metamorphic Rocks The most common names are derived from the metamorphism of shale. At low grades of metamorphism (typically around 300 o C), one of the first chemical reactions to take place place converts clay minerals that formed during weathering, into micas such as muscovite (white mica) and chlorite (green mica).

STONE FACTS;should answer the most basic questions . . . However, instead of forming from a pre-existing limestone (like marble), slate is formed from the low-grade metamorphism of the sedimentary rock shale. Slate, like shale (mudstone), is a very fined-grained rock of mostly microscopic clay minerals with some microscopic quartz and calcite. Slate can also contain some of the same minerals found in granite, which make some slates iridescent and/or hard. The alteration of shale by heat and pressure produces the pronounced partings (slaty cleavage) that give slate its characteristics. Like limestone and marble, the color comes from trace metals.

Shale Shale is a sedimentary rock composed of very fine clay particles. Clay forms from the decomposition of the mineral feldspar. Other minerals present in shale are quartz, mica, pyrite, and organic matter. Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor. Geologists estimate that shale represents almost ¾ of the sedimentary rock on the Earth’s crust. Geologists are specific about the definition of the rock called “shale.” Shale is composed of clay particles that are less than 0.004 mm in size. Relation to Mining Typically, common clays and shales are dug from open pits, and these pits must be near the processing plants to minimize production costs.

Pictures of Sedimentary Rocks Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris.hemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution. Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.

Sedimentary rock Sedimentary rocks include common types such as chalk, limestone, sandstone, clay and shale. Sedimentary rocks cover 75% of the Earth's surface. Four basic processes are involved in the formation of a clastic sedimentary rock: weathering (erosion)caused mainly by friction of waves, transportation where the sediment is carried along by a current, deposition and compaction where the sediment is squashed together to form a rock of this kind.

- Feldspar often combines with quartz to make a much harder igneous rock called granite. Feldspar and pyroxene combine to make basalt. When feldspar is in contact with wind or water, the wind and water gradually grind the feldspar down into tiny grains that become one kind of clay called kaolin.

- Shale is usually found in thin layers. The silt or clay that composes shale is made of very small pieces of weathered rock. The pieces are from 1/16 to 1/256 of a millimeter in diameter. The color of a sample of shale is that of the clay or silt that it was formed from.

Facts About Soil: What It is Made of and How It Forms Mechanical weathering does the same thing to all rocks: breaks them down into small pieces, which eventually become the size of sand, silt, and clay. Sand, silt, and clay are primarily measures of grain size. Sand grains have a diameter from 1/16th to 2 mm.Silt is between 1/256th and 1/16th mm, and clay is anything less than 1/256th mm. Sand looks like individual grains and feels gritty to the fingers.echanical weathering does the same thing to all rocks: breaks them down into small pieces, which eventually become the size of sand, silt, and clay.

- Examples of sedimentary rocks include limestone, sandstone, mudstone, greywacke, chalk, coal, claystone and flint. Limestone forms the metamorphic rock marble when subjected to extreme heat and pressure over time (metamorphism). Sandstone forms the metamorphic rock quartzite. Mudstone forms the metamorphic rock slate. Chalk is a soft, white form of limestone. Flint is a hard, sedimentary form of the mineral quartz.

- Clastic sedimentary rocks form when individual grains (the sediment), made by fragments of rocks, minerals, or shells, are cemented together (the clastic sediemntary rock).These are the only type of rock that is NOT made simply of crystals, but rather fragments of other materials, broken and then reassembled together.he most common clastic sedimentary rocks are breccia and conglomerate (formed from gravel), sandstone (from sand), siltstone (from silt), and shale (from clay). B. CHEMICAL SEDIMENTARY ROCKS. Chemical sedimentary rocks are crystalline, that is made of crystals interlocked with each other.

Plz explain me what is 3dB frequency means.And its importance? I assume you are asking about the 3dB point with respect to filters? The 3dB point, or 3dB frequency, is the point at which the signal has been attenuated by 3dB (in a bandpass filter).This is generally considered the point for determining the filter's bandwidth. The bandwidth is defined as the difference between the upper and lower 3dB points.For example, if you have a filter which has a lower 3dB point of 720 MHz, and an upper 3dB point of 730 MHz, you have a bandwidth of 10 MHz. assume you are asking about the 3dB point with respect to filters? The 3dB point, or 3dB frequency, is the point at which the signal has been attenuated by 3dB (in a bandpass filter).

- Soils are chemically different from the rocks and minerals from which they are formed in that soils contain less of the water soluble weathering products, calcium, magnesium, sodium, and potassium, and more of the relatively insoluble elements such as iron and aluminum.olloidal particles are so small (2:1 clays, while kaolinite is a 1:1 clay mineral. Clays having a layer of aluminum oxide (octahedral sheet) sandwiched between two layers of silicon oxide (tetrahedral sheets) are called 2:1 clays.

Human skeleton Movement is powered by skeletal muscles, which are attached to the skeleton at various sites on bones. Muscles, bones, and joints provide the principal mechanics for movement, all coordinated by the nervous system. It is believed that the reduction of human bone density in prehistoric times reduced the agility and dexterity of human movement.

- Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call mud.This composition places shale in a category of sedimentary rocks known as mudstones.hese tiny grains are usually clay minerals such as illite, kaolinite and smectite. Shale usually contain other clay-size mineral particles such as quartz, chert and feldspar. Other constituents might include organic particles, carbonate minerals, iron oxide minerals, sulfide minerals and heavy mineral grains.

Mudstone Mudstones form when very fine-grained clay particles are deposited in water. They tiny particles settle to the bottom of oceans, lake floors or lagoons or even in quiet stretches of rivers. As the mud is buried and compacted by overlying sediment, the water is squeezed out and it turns into mudstone.

3 Types of Rock for Climbing: Granite, Sandstone & Limestone Limestone, another type of sedimentary rock, forms under different circumstances than sandstones. Limestone, forming about 10% of the world’s sedimentary rocks, are formed underwater in ancient coral reefs and from shells and skeletal fragments of living organisms.

- Clay is imagination-inspiring, malleable, healing, abundant, accessible--and messy. That’s the glory of clay. What Clay is. The earth’s crust is made up of largely igneous rock, which, as nature breaks it down, becomes clay. It has been being formed for millions of years, since the time of the glaciers. The main ingredients in clay are alumina, silica and water.

Rocks and soil Rocks are made of one or more minerals. There are three main classifications of rock, based on the way the rock was formed: sedimentary, metamorphic and igneous. Soil is formed of fine rock particles mixed with air, water and particles from dead plant and animal matter.There are three main types of soil which are classified according to the amount of sand and clay in them.ther rocks are made from two or more minerals – for example, granite is made from feldspar, mica and quartz. Common minerals that form rocks include: feldspars, mica, quartz, calcite, dolomite, amphiboles, pyroxene and olivine. Rocks are used for a range of purposes depending on their properties.

- The talc is formed by the alteration of sedimentary magnesium carbonate rocks (dolomite and magnesite) at elevated temperature and pressure below the earth's surface. While the magnesium is fixed in situ, the silica is transported by silica-containing hot fluids to react with the Magnesium- bearing carbonates to form talc. These altered rocks are then talc-rich dolomites or magnesites. This type of deposits usually deliver the massive talcs accompanied by carbonates, chlorite and some quartz.
