Prospectivity mapping, also known as mineral prospectivity mapping or mineral potential mapping, defines a process used to make better use of mineral exploration data. . Geological and geophysical datasets, such as lithological, structural and topographical maps, aeromagnetic, gravity and radiometric imagery are the typical datasets used in the construction of prospectivit
The plus–minus method, also known as CRM (conventional reciprocal method), is a geophysical method to analyze seismic refraction data developed by J. G. Hagedoorn.It can be used to calculate the depth and velocity variations of an undulating layer boundary for slope angles less than ~10°.
Traditionally prospecting relied on direct observation of mineralization in rock outcrops or in sediments. Modern prospecting also includes the use of geologic, geophysical, and geochemical tools to search for anomalies which can narrow the search area. Once an anomaly has been identified and interpreted to be a potential prospect direct ...
Geobotanical prospecting refers to prospecting based on the composition and health of surrounding botanical life to identify potential resource deposits. [1] Using a variety of techniques, including indicator plant identification, [2] remote sensing [3] and determining the physical and chemical condition of the botanical life in the area, [4] [5] geobotanical prospecting can be used to ...
In archaeology, geophysical survey is ground-based physical sensing techniques used for archaeological imaging or mapping. Remote sensing and marine surveys are also used in archaeology, but are generally considered separate disciplines. Other terms, such as "geophysical prospection" and "archaeological geophysics" are generally synonymous.

Transient electromagnetics, (also time-domain electromagnetics / TDEM), is a geophysical exploration technique in which electric and magnetic fields are induced by transient pulses of electric current and the subsequent decay response measured.
Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.
