Elemental Analysis of Some Rock Samples from Namakkal, Tamil Nadu, India

The Earth is the third planet in the solar family from the sun. The more that we know about our planet, especially its environment and resources, the better we can understand, use, and appreciate it. To us the Earth is the most important body in the universe. In the broader view, however, the importance of the earth shrinks. At least a half dozen stars are know to have faint, unseen companious. But it's not know whether these companions are very faint stars or massive Planets revolving about the observed star. Thus the earth appears to be an average planet. However, at least in the solar system, the earth is unique. In having abundant water, exemplified by the oceans, and an atmosphere that can support life. Solid crust of the earth is made up of various types of rocks, which are very useful to man in his day-to-day activities. The rocks are aggregate of mineral substances. Minerals are natural inorganic substances, with a definite chemical composition or range of composition. When they are perfectly grown, they assume certain geometrical shapes by which they can be easily identified. Mineral study holds an important key role in nation's economy, in the sense, that the ores may profitably be extracted. The different properties of minerals can be studied in detail based on the chemical composition. The elements of the earth's crust rarely occur individually in nature, but they are generally found in chemical composition with some other elements in the form of compounds.
