Dangerous hair products In recent years, many people are choosing natural products for hair and skin care. The main reason for that is the fact these products are full of chemicals and harmful toxins that may have a negative impact on the health. Many researches and studies have shown that nutrition is very important, but it is not the only way how the toxins and chemicals can get into the bodies. Another option that is often completely disregarded, is by regularly using and applying certain products

amounts. Mineralogy in hand sample is k-feldspar, plagioclase, quartz, biotite, magnetite, with trace amounts of hornblende. Texture (hand sample): Overall grain size is coarse grained, with a porphyritic texture, non-foliated. The hand sample has a porphyritic texture with pebble sized, euhedral k-feldspar grains and the remaining minerals are generally coarse grained. The overall grain sizes are coarse with an average around 1 mm in size. The k-feldspar grains have rapakivi texture, with the plagioclase

It is heterogenous as it is massive but also has areas which show relict igneous textures. The ophitic texture between pyroxene and plagioclase feldspar ( the former enclosing the latter) shows that the pyroxene crystallised from the magma before the plagoclase feldspar. The presence of hornblende in the rock shows retrogression from granulite facies to amphibolite facies The hornblende retrogresses from the pyroxene* . Pegmatite Pegmatite is quartzo-feldspathic

the way the colors were captured in the light. While rainbow moonstone caught my eye, moonstone comes in so many beautiful colors and types making it a powerful and diverse stone. Geologically speaking moonstone is a mix of two feldspar species, being itself a feldspar. Orthoclase is the first and is a main “ingredient” in granite. It is also used to make several types of porcelain and ceramic. Albite the other mineral isn’t as widely used but is found in some metamorphic mineral deposits. Moonstone

below the crust that is composed of silicate rocks that are richer in iron and magnesium. The boundary between the Crust and the Mantle is the Moho (Mohorovicic discontinuity). Above the Moho are rocks containing plagioclase feldspar, below it are rocks containing no feldspars. Outer Core: see above Inner Core: see above Plates - Tectonic plates are the pieces of the Earth's crust that "float" on the asthenosphere and make up the

rock is Gneiss Idaho springs and it doesn't have a grain size. Some of the minerals in the rock were K-feldspar, quartz, Biotite, and Hematite. The environment of deposition would

North Carolina is an important part of the United States for three major reasons which revolve around economy. North Carolina is important because of its manufactured goods, resources and power, and agricultural products. North Carolina is one of the top manufacturing states in the country. They produce computers, electronic communications equipment, chemicals, and machinery. North Carolina has been at the top, as one of the most successful manufacturing state in the US for almost a century.

cools down in a deeply buried body (or pluton) and forms then hardens into a rock without reaching the surface. Due to the slow cooling process, granite has large mineral grain that fit together. Granite always consist of the minerals quartz and feldspar which gives granite a light color. They say, “It is not granite without quartz.”

consist on a broad scale quartz, feldspar, plagioclase, calcite, dolomite, pyrite, chlorite, kaolinite, and illite. Marcellus shale has long been known as a major source rock, while Pottsville shale is potential caprock for CO2 storage. X-ray diffraction (XRD) experiments were conducted on both shale samples by Olabode and Radonjic for the compositional data. Comparing the source rock and caprock, both rocks has similar tectosilicates content (quartz and feldspar) around 50%. The main differences

commissioned by Gudea himself. The statues were placed in each of the temples that he rebuilt. This statue is dark and serious. The statue is carved from Diorite; an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar, biotite, hornblende, and/or pyroxene. https://en.wikipedia.org/wiki/Diorite. The Statue of Gudea has a smooth shiny finish to it. The detail carved into the statue shows this figure to be one of wealth and status. The shape of the hat and the

The Disappearing Spoon Summary Veronica Sanchez Chemistry 9/3/14 The Disappearing Spoon Summary In the beginning of the first chapter Sam Kean shows the periodic table without the elements. The periodic table has 18 columns, 7 rows and 2 extra rows hovering on the bottom. There are 112 elements with more pending. All of these elements are placed specifically, and cannot be moved or else the whole structure would collapse. Where the elements are determine almost everything scientifically

The rocks are pebble to cobble sized basalt fragments. The samples collected ranged from 50mm to 120 mm. The rocks are angular. They have a gray, very fine ground mass. Fine plagioclase feldspars are visible throughout the ground mass and sparkle in the sunlight. The rocks do not show signs of heavy weathering. There is some white staining visible, but there is very little red or brown staining. The rocks have abundant vesicles. There is

eroded over time (SERF, 2012).This creek system and its water flow seeps into the surrounding rock and slowly weathers this creating deeper runs of water and wider bends etc. Chemical weathering also affects this creek system with different minerals (feldspar in this case) in the granodiorite being broken down causing different chemical compositions. Porous weathered rocks are important in the sense that they store nutrients that can be passed onto invertebrates and plants within the creek system. Before

1.1. Locations for Mining 1.1.1. Mining the Moon The Moon’s deep gravity well requires a high escape velocity to launch materials from its surface and, similarly, a high amount of thrust to enable a soft landing from lunar orbit [112]. However, this heavy gravity also means that the design of structures and materials handling processes on the Moon could be comparable to that of Earth, making it possible to apply the civil and mechanical engineering principles as applied on Earth [113]. As a result

Should Nuclear waste be stored in Underground salt mines and Sinkholes ? Some scientist think that we should send some nuclear waste into sinkholes and Salt mines because they think that it is a safe place and can't damage anything. But they are wrong because Nuclear waste can be very deadly when it is left unattended deep underground or in a Salt mine. The most common rock in the United States is Limestone. Limestone is a Sedimentary rock which covers about 85% of the United States , and 10% of

OBSERVATIONS 1. Igneous Rocks The only igneous rock we observed during the Baraboo trip was the Baraboo Rhyolite. Located by the highway, we took note the rock’s red color and lack of cleavage (see Appendix 1.1), signifying that it was made of potassium feldspar and quartz. It had no obvious bedding, and we quickly concluded it was the Baraboo Rhyolite due to its color and lack of prominent features (e.g. fossils). However, we did notice that the rock had the faintest

GRANITE RAILWAY (MASSACHUSETTS) Your Name Professor’s Name Course Number Date GRANITE RAILWAY (MASSACHUSETTS) Railroads are the strangest way of transportation in the 19the century and it is the unprecedented way to think it to use the railroad (the wheeled vehicles run on the rail) for commercial perspective. In the United States, Granite railway is viewed as the first commercial railroad in the country. It was started constructing on 4th March, 1826 and began operating on 7the October

THE ELEMENT SILICON. The element silicon was named after the latin word for hard stone or flint (silex). It is considered to be the seventh most abundant element in the universe and the second most abundant on the earth, (27.7%) after oxygen. Being a stable tetrahedral, the element is chemically considered to be highly versatile or reactive. Silicon is a tetravelant metalloid of atomic number 14, the element posses the properties of both metals and non-metals. Its chemical symbol is Si and it has

“Moe” Berg was a man of mystery. He played in Major League Baseball(MLB) for fifteen seasons and never started; he was good, just not good enough. Moe Berg had a strong arm, nimble reflexes and soft hands, but most importantly he had the brains. Franklin Delano Roosevelt once said to the head of the spy agency, “Give my regards to the catcher”(Buchard et. al.). He most likely said that because Moe Berg was about to go on a mission. An average MLB catcher, Moe Berg, greatly informed the US military
