geophysical instruments developed utilizes unique technology to achieve its aim. There are instruments that are available in the market. To begin with, there is the electrical resistivity method. It uses electrical resistivity of the ground to get information about an area. The device used has probes that are inserted into the ground before electric current is connected to them. Usually four probes are inserted. The data on resistivity of the area obtained will then be used to determine the kind of mineral present in the region as each mineral has certain amount of resistivity. Electromagnetic conductivity method is also in use. The method has a lot of similarity to the resistivity method as conductivity is the opposite of resistivity. However, this method does not give very accurate data as the resistivity process. Its main advantage is that its use does not require that the equipment comes into contact with the ground making the process faster. Another technology that is used in mineral exploration is the Ground penetrating radar. This technology uses the radar technology that has been for a very long time been used to track air-crafts that are airborne in an area. The machine used for this process sends electromagnetic pulse to the ground. The reflected pulse from the ground is then picked by the machine and used to determine the type of rocks beneath the ground. The time the wave takes helps to establish the depth of the rocks. Lastly for any data collected to be analyzed so that they can be understood and used, very powerful computers using specialized software are used to analyze the data the methods collected. For each method, the kind of software used is unique to it. Since 1930s, several methods have been developed by scientist to enable mineral exploration to do their work easily and cheaply.
