Petrography deals with the examination and analysis of the rocks. It is a branch of petrology, which encompasses various different aspects of geology. It provides detailed and comprehensive descriptions on rocks and minerals. The person who studies this branch of petrology is called a petrographer. In this study, the mineral content and the textural relationship are discussed and represented in an extensive manner. These descriptions initiate with field observations and they are concluded in petrographic laboratories. To analyze the specimens, thin-sections and minerals, the best tool to use is the photomicrograph microscope. This tool offers in-depth and quality review of the overall target. The detailed and well-researched descriptions of the minerals via optical mineralogy are vital for gaining the information about the original composition of the rock. Owing to the progress in technology and availability of modern technical tools, it has become possible to focus on the individual grains as well as the entire rock. To do this, the methods like atomic absorption are employed. They small grains can also be examined with the aid of the X-ray diffraction. These methods are crucial and could provide the desired information detail. In laboratory, petrologists have the opportunity of analyzing the minerals and rocks in detail. They use the synthesizing methods to maneuver the conditions in lab to study the formation. In this lab experimentation, the researchers employ different modern methods and tools to come up with the detailed analysis. They test them in different conditions based on the hypothesis, in order to learn the procedure of rock formation in nature. Such laboratories are fully equipped with different high class equipment such as mass spectrometer to study the rock samples, and present the comparison between different samples. The field of petrography is divided amongst different subfields and areas of interest. You may use the terms like sedimentary petrology, and metamorphic petrology to describe the different fields within this vast area of study. However, sometimes, there is a significant overlap between different researchers in this field as the rock does not often contain itself to one specific niche considering the convenience of the scientists. Based on each one’s area or field, the applications could encompass different aspects and seemingly irrelevant features. For example, in petrology, the opportunities for the scientists could range from the volcanoes to the deserts. There are various applications and implications of this field in the industry as it has been made use of, by different vendors, oil and mining companies. Moreover, experts of this field may also get themselves associated with the vendors who intend to learn about these materials in detail. They are helpful for providing the engineers necessary aid to complete their research projects. Petrologists could become curators providing services in places that store rock samples for their historic worth and importance. All in all, this area of study is highly extensive and holds crucial importance for numerous applications and purposes.
