Paragraph 1 The main structure mentioned in the article will be FePO4. The article analyses and discusses on a quartz-type compound‚ the Iron phosphate FePO4 and its structural evolution. In this assignment‚ the quartz will be referred to as SiO2. Under an experiment conducted‚ the temperature was ranged within 294K to 1073K. At high temperature‚ the structural parameter of FePO4 would converges to a β-quartz whereas it will converges to a α-quartz at lower temperature. As for the phase transition

Porphyritic granite Porphyritic granite is an igneous rock‚ which consists of orthoclase feldspar‚ quartz and orthoclase. This type of rock is made up of two different grain sizes‚ larger crystals referred to as phenocrysts‚ and smaller granite sized grains. The name for porophyritic originated from the Latin word porphyry which is defined as purple‚ and is known as a color royalty. This rock has been used as early as 18 AD and was discovered by a Roman legionnaire named Cauius Cominius.

The ancient Egyptians used it as makeup and today we use it in many ways‚ “it” is the element antimony. Discovered by the ancients‚ this element serves many purposes (it is no longer used as eyeliner‚ like it was for them)‚ but also has many negative effects on people and the environment. Antimony is a metalloid found in group 15. It is a silvery lustrous rock‚ and its standard state is a solid. It is a poor conductor of heat and electricity. Antimony has many universal applications that

Jessica Guerrero Geology 110 November 30‚ 2009 Chapter 6. Weathering Describe the role of external processes in the rock cycle. External processes include weathering which is the disintegration and decomposition of rock at or near earth’s surface. Mass wasting which is the transfer of rock material downslope under the influence of gravity. And erosion‚ which is the removal of material by a mobile agent‚ usually water‚ wind or ice.. These are all called external processes because

Curriculum Resource Kit: Rocks Rocks are everywhere‚ they cover the whole earth. It is the foundation of the surface we live in. So‚ we basically live on rocks. They can be a part of a 5000 old year old ancient pyramid to the cement we walk on under our feet as we take a stroll on the street or in the park.
