These are processes and procedures that are meant to measure rock magnetism. Although this is their primary functions, they can aid find minerals that are not magnetic in nature notably gold. Over the years, they have been used in areas prospected to have iron ore thus bumping into gold was initially a mere coincidence. This 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.
The ground magnetic surveys are applied in looking at the arrangement of the primary rock. They will find folds and faults that may be concealed by the cover rock. They will also find out demagnetized areas which are related to hydrothermal actions.
Magnetic rocks are destroyed by hydrothermal activities. As time passes by, ordinary rocks that are capable to attract magnet are demagnetized by heat. In case of this occurrence, rocks in demagnetized regions are not recognized using the ordinary magnet-attraction-ability survey. This will require a regional level aeromagnetic survey. The good thing about this procedure is that it is sophisticated which enables it to recognize deposits of gold.
The survey using magnetism is usually done by two operators. They virtually walk across the study area. Therefore, for this task fitness is paramount. The objective is walking across the landscape in a straight line amidst some obstacles. Bigger obstructions can happen in areas having big vegetation and other risks like scorpions and snakes. In these landscapes, the operators should walk slowly and pay close attention and concentrate more. This job gets easier in the level grounds since the operators can even walk to fifteen kilometers per day.
Technology plays its part as each operator walks across the area of interest armed with a magnetometer and GPS. Any changes on the earths field that able to attract magnet are recorded along the extended side of each line that an operator has walked along. The GPS readings are also recorded keenly and the plotted area marked as accurately as possible. The few obstructions are negligible and do not affect 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.
After the fieldwork, the collected data will be interpreted by a geophysicist. This expert separates artifacts brought by past human activities and studies the natural phenomenon. This interpretation is both artistic and scientific for there are certain filters to identify the various aspects of magnetic gradients to reveal structures associated with the mineral occurrence.
