They are the procedures and processes which are applied in measuring rock magnetism. This is their major function although they can assist in finding non-magnetic minerals such as gold. In many years, they have been applied in locations that are likely to have iron ore existence. It was a coincidence finding gold using the procedures. Here is what you need to know about a ground magnetic survey company
Based on the principle of magnetism, the ground magnetic surveys are functional when mapping the magnetism of the underlying rocks. In most instances, it is used in the identification of magnet-attraction-ability rocks like magnetite and iron sulfide. Once these particular metals are found in pure form, and in large amounts the area is marked as an iron ore zone. There are particular iron sulfides that have very high chances of having gold. Therefore identifying them positively can show unexpected amounts of gold which will be more valuable than the magnet-attraction-ability materials.
Ground magnetic surveys are also utilized to understand the underlying rocks general structure, identifying faults as well as folds otherwise hidden underside cover rocks as well for identifying demagnetized zones that are associated with hydrothermal activity.
Hydrothermal activities are harmful or destructive to the rocks that have ability to attract a magnet. Over some time, the heat will demagnetize the natural magnet-attraction-ability rocks. After this happens, these rocks in the demagnetized areas cannot be identified via a local magnet-attraction-ability inspection. This requires an aeromagnetic survey since the technique is advanced and has the advantage of getting some gold deposits.
The magnetic survey is conducted by two operators. The operators practically walk across the area of study. For this reason, fitness is a key factor. The aim is to walk across the landscape following a straight line as much as possible amidst certain obstacles. Greater obstruction may occur in areas with thick vegetation save for the risk of snakes and scorpions. Such a landscape also demands that the operator will be limited in speed and has to pay key attention and keep concentration at its peak. The task is, however, simpler on level ground, and the operators may walk up to fifteen kilometers in a day.
Technology is also beneficial in the activity. This is because the operator uses a GPS and magnetometer while walking in the region. The magnet-attraction-ability region may have changes which will be recorded on the length that the operator is walking on. It is important recording the readings on the GPS carefully. The plotted region should be marked keenly. Minor obstructions will not change the results.
Every operator should mark the walked on paths with a dissimilar color. The recorded variations in the magnetic field deviations in the paths of the operators will aid analyze the field correctly. The landscapes that are significantly elevating and changing are recorded by the GPS. The raw data is ultimately fed into the computer software to come up with a 3D model of the surveyed land. In each survey, operation stations are created from where the days variations of the magnet-attraction-ability fields get recorded.
When the fieldwork has been completed, a geophysicist will interpret the information. The specialist will segregate artifacts from human processes and natural phenomenon studies. The data will be scientific and artistic.
