What is rock geology?

Rock geology is a science that studies the land of the earth. It analyzes different physical properties between different types of rocks, which are rocks composition and how the rocks are in their position. This study is essential to understand the history of the planet and how it has been created in its current state. In industry, rock geology is necessary to determine safety in mechanical engineering and alleviating problems associated with building on new surfaces. In the third century BC, he published the book on Stones . He held his authoritative attitudes until the early Middle Ages. Abu Al-Rayhan Al-Biruni in the 11th century introduced new concepts on rock geology. He did the case that India was once part of the ocean to explain the diverse rock formations and the fossils he found. Through his work he influenced a number of natural philosophers who would become the principles of geology in the Renaissance.

In 1785, James Hutton introduced modern theory of rock geology in paper for Royal Society EDInburgh. He created the theory that the mountains had disrupted over time and turned into sediments. These sediments then formed into new rocks in the sea and eventually returned to the dry country. Hutton has determined that the rocks can inform humanity about the real age of the country.

According to rock geologists, the rocks are organized in three types: sedimentary, igneous and metamorphic. The type is designed according to how the rock originally created. Igneous rock is crystallized from magma or lava. When this rock is eroded or otherwise weathered, it is considered to be a sedimentary rock. The sedimentary rock in turn becomes metamorphic rock when it is subjected to intensive pressure or heat. All three can be melted again and start the cycle.

Rock geology relies strongly on field work. Because the rocks are found in nature, geologists usually have to travel where rock deposits are located. For mapping and identifying mountainsNin and their structures are performed by various practices. Geological mapping allows the geologist to formulate the theory of full structure and location of various rock formations. This helps to determine the level and process of erosion as well as the location of possible archaeological remains. Different methods of rocks identification, including seismic tests and physical analysis, are performed.

While the geology of rock in the field is important, laboratory work is also very important. Petrologists use two main methods to identify rocks in the laboratory, both highly reliable. Scientists use either electron micro -project or via optical microscopy. The process of using an electron micro -project includes the extraction of chemical composition to determine the development of rocks. In optical microscopy, thin parts of the rock are analyzed by polarized light to identify the different properties of the sample.
