Airborne magnetic acquisition
Method of measuring the geomagnetic field strength using an aircraft
Example: The Geological survey of Norway has more than 60 years of experience with airborne magnetic acquisition and together with TGS has acquired aeromagnetic data over Norway and almost the entire Norwegian shelf.

Basement lithology
Description of basement rocks based on color, structure, mineral composition and grain size
Example: The data contribute to characterize the underlying basement lithology on the Norwegian shelf, understanding better the tectonic processes of the sedimentary basins and the crustal heat flow.

Geological reconnaissance
A complex of various special geological and other works carried out for the purpose of searching, detecting and preparing for the industrial development of mineral deposits
Example: The application of magnetometry ranges from very local, detailed mapping to basin and crystal scale regional geological-tectonic reconnaissance.

Geological settings
Characteristics set of of the components of the geological environment for the studied area
Example: The methodology records variations in the ambient earth magnetic field, which relates to different magnetic susceptibilities caused by variations in the crust mineral composition and therefore can distinguish between different geological and tectonic settings.

Geological survey
A systematic examination of an area to determine the character, relations, distribution, and origin or mode of formation of its rock masses and mineral resources.
Example: The Geological survey of Norway has more than 60 years of experience with airborne magnetic acquisition and together with TGS has acquired aeromagnetic data over Norway and almost the entire Norwegian shelf.

Instrumentation
noun
It is a term for measuring instruments that are used for indicating, measuring and recording physical quantities.
Example: Significant technologically achievements in instrumentation and positioning made the application a fast and effective method to map geological and tectonic settings over large areas.

Magnetic susceptibilities
In electromagnetism, the magnetic susceptibility (Latin: susceptibilis, "receptive"; denoted χ) is a measure of how much a material will become magnetized in an applied magnetic field.
Example: The methodology records variations in the ambient earth magnetic field, which relates to different magnetic susceptibilities caused by variations in the crust mineral composition and therefore can distinguish between different geological and tectonic settings.

Mainland
The continental (i.e. non-insular) part of any polity or the main island within an island nation.
Example: Further development of magnetometers and especially the establishment of global positioning systems initiated an ongoing programme to update the magnetic maps with new state-ofthe- art aeromagnetic data for both the Norwegian continental shelf and the mainland of Norway.

Onshore shelf
Mainland shoal
Example: The Geological Survey of Norway (NGU) has acquired aeromagnetic data for almost 60 years and has initially covered onshore Norway and the Norwegian continental shelf during 1959 and 1975.

Positioning
noun
Ensuring synchronization of location, speed and time.
Example: Significant technologically achievements in instrumentation and positioning made the application a fast and effective method to map geological and tectonic settings over large areas.
ru: Позиционирование
Potential field measurements
Conducting a geophysical survey
Example: Gradient data for both the gravity and magnetic field became more and more common during the last decade and represents the next generation of potential field measurements, providing much higher resolution data and a set of independent data for the tensor field of the potential.
ru: Измерение значений потенциального поля
Remote sensing
The acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation
Example: The fast development of instruments which measure magnetic field variations with very high sensitivity makes it today possible to also map small changes from remote sensing platforms like aircraft and even satellites.
ru: Дистанционное зондирование
Seafloor spreading
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other.
Example: In the oceanic domain, seafloor spreading anomalies are predominant to identify the limit of the oceanic crust and allow plate reconstruction to better understand the opening of the North Atlantic.

Sensitivity
The ability of the measuring device to measure small signals
Example: The fast development of instruments which measure magnetic field variations with very high sensitivity makes it today possible to also map small changes from remote sensing platforms like aircraft and even satellites.
ru: Чувствительность
To map
verb
A visual description of the process by generating maps of the current and target state of the process
Example: Significant technologically achievements in instrumentation and positioning made the application a fast and effective method to map geological and tectonic settings over large areas.
