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
Ground magnetic surveys are beneficial in identifying magnets below rocks. In many cases, they try to find general rocks that have magnet-attraction-ability like magnetite and iron sulfide. An iron ore is a location where the two metals are identified in huge quantities and clean form. It is important being aware that there are specific iron sulfides with a high probability of having gold. Thus, identification of these substances will help in finding a huge amount of gold. This is something that is quite valuable.
These ground magnetic surveys are also used in the comprehension of the underlying rock structures as well as in the identification of folds and faults hidden under rocks and checking out the demagnetized areas linked to hydrothermal activity.
Hydrothermal activities have been found to be destructive to rocks that are capable to attract magnet. Over time, the heat demagnetizes natural rocks hat are capable to attract magnet. When this occurs, such rocks in the demagnetized zones cannot be identified through a local magnet-attraction survey. It calls for the aeromagnetic survey at a regional level. This technique is more advanced and has the merit of identifying possible gold deposits.
Two operators usually carry out the magnetic survey. On the study area, these operators will walk on it. This is a reason why one should be physically fit. The plan is walking on the landscape on a straight line despite having several obstacles. Thick vegetation can cause major obstructions. Also, chances are high to find scorpions and snakes. This type of landscape will limit the speed of the operator. This is because the individual has to concentrate and be attentive. This job will be easy on a leveled ground. It is worth noting that operators can in one day walk for fifteen kilometers.
Technology is also a great part of this process since the operators have to have a GPS and a magnetometer. Any minute change in the earths magnet-attraction-ability field gets recorded along the line length of each side where the operator walks on. The GPS readings should be done accurately and the plotted section marked as correctly as possible. The small barriers are insignificant and cannot affect the final results.
Different colors are used by the operator to mark the paths they have walked on. The magnet-attraction-ability field changes which are recorded on the paths of the individual operator will aid in the accurate analysis of the field. If there are considerable changes in the landscape and elevation is identified by GPS. The unrefined data is captured in computer software. This will help in developing a three dimensions model of the surveyed area. Operation station is developed for each survey which helps in recording changes of the magnet-attraction-abled field.
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.
