Geophysical Consultants Geophysical consultants are capable of evaluating extensive geophysical surveys which are used by mining companies, individuals in need of geoscientific information, and by governments for map development and understanding the concentration levels of various minable resources in certain regions.
There are many benefits of conducting a geophysical survey using the experience and knowledge of a qualified geophysical consultant. Companies such as these have access to sophisticated tools, aircrafts, and data acquisition systems that will ensure that the highest quality of data is obtained.
A capable geophysical consultant will not only be useful in attaining necessary data, but will also conduct assessment and analytics of the geophysical data gathered during a survey.
A geophysical survey can be a costly procedure therefore, it is of utmost importance that it is conducted as accurately as possible. The data that is acquired during a geophysical survey is commonly an instigating factor in an expensive mineral exploration. As such, the value of the resources uncovered during a mining expedition will ideally surpass the cost of the geophysical survey, in order to render profit.
Geophysical consultants specialize in both ground and airborne geophysical surveys, mainly magnetic, electromagnetic and gamma spectrometric.
Data acquisition systems used in these geophysical surveys are well-advanced technological devices that are capable of attaining the most accurate information available. Characteristics of the data acquisition systems used by experienced geophysical consultants are:
  • Multiple magnetometer inputs
  • Real time graphical display
  • Multiple analog inputs
  • Immediate quality control
  • Navigation interface for the majority of GPS instrumentations
  • Flight path planning
On top of using sophisticated data acquisition systems, geophysical consultants have access to specialized aircrafts that have been developed specifically for geophysical surveys. Using fixed wing horizontal gradiometers, surveyors can measure the earth's horizontal magnetic gradient. This is a key factor for detecting magnetic sources that are close to the Earth's surface.
By using fixed wing horizontal gradiometers, it is also possible to detect the following:
  • Magnetic axis within magnetic units
  • Small anomalies and their precise location between flight lines
  • Capable of discriminating between small geological sources and cultural sources
  • Can indicate the dip of magnetic units
Gradiometer data is used in the exploration of kimberlite and it is useful during detailed surveys that involve flying the aircraft close to the ground.
When it comes to map development, geophysical consultant companies use structural multi-view systems as a means of a cost-effective and efficient detailed structural mapping tool.
Structural multi-view systems combine the use of electromagnetics, radiometrics and magnetics and can conduct low speed flight surveys at low altitudes in order to attain precise terrain details.
When conducting geophysical surveys, accurate data is extremely important, as well as sufficient capabilities of analyzing and applying the data acquired. As such, professional geophysical consultants ensure that each survey is conducted as cost-efficiently as possible, and can aid in analyzing the results so that they may be used accordingly.
