The Umeshwar Prasad Economic Geology Pdf 456 is a resource written for geologists and teachers who want to learn about mineral deposits and economic geology. The main idea behind Economic Geology is the exploitation of subsurface resources, such as minerals and fossil fuels, in order to produce wealth. This document will introduce the relevance of mineral deposits and the relevance of economic geology. It will also outline some aspects that need to be considered before economic development can take place. Finally, it will conclude by summarising the components that compose an economy as well as their role in providing access to natural resources such as mineral deposit or fossil fuel extraction activities. Economic geology is the study of the mineral deposits in a given area and how they are extracted. It aims to identify profitable mineral deposits and to determine how they may be developed. There are two main components of economic geology, which are geological mapping and geochemistry. Geological mapping involves the drawing of a map showing the location of all mines in an area. It also collects data on how much rock has been mined, from when it was mined, the amount produced from each mine, from where it was mined from and so forth. Geological mapping also helps predict future mining in the area by collecting data on any new discoveries in a mine that has been in operation for a long time. Geochemical analysis involves the analysis of rock in order to determine its mineral composition. A geologist will use these chemical analyses to identify the type of mineral it contains. The physical, chemical and geographic relationships between deposits are also studied. One example of economic geology is the exploitation of fossil fuels. First, the exploration phase takes place in order to search for an appropriate location for drilling. Once a location has been found, drilling may begin. There are many methods used when searching for fossil fuel deposits although they all have the same purpose- to explore for coal, oil or natural gas in a geological environment that makes its extraction feasible . There are several tools that can be used to determine a suitable location for a drilling site. One of the most common is geochemical analysis. By examining the composition of rocks, geologists can determine whether or not they will contain any fossil fuels. This method is also very useful because many mining sites have been abandoned once the fossil fuel has been exhausted. Geochemical analysis can be used to determine if there are any other valuable minerals left in these abandoned mines, such as copper or silver . Once a drilling rig has been assembled and all regulatory approvals have been acquired, drilling may begin. This process consists of drilling down into the Earth's crust and then horizontally into the coal seam or oil-bearing rock formation that needs to be accessed . Drilling is done in different ways. One is the rotary drilling method used for conventional oil and gas. This consists of using a top-drive drilling rig to drill vertically through the ground, usually between 6500 ft and 10000 ft. The drilling rig can rotate 360 degrees, which is very convenient since no one will need to climb inside the rig. Another method of drilling consists of using a directional drilling rig. This involves inserting holes around different sides of the wellbore every 50 feet, towards each end of it . There are many types of hardware that are used in the process. cfa1e77820
