What is a geochemical survey?
(b) Geochemical surveys are surveys of the chemistry of mineral deposits. They are done by, among other things, sampling soils, waters, and bedrock to identify areas of anomalous mineral values and quantities that may in turn identify mineral deposits.
How is geochemical survey done?
Geochemical Exploration Such surveys are normally done by sampling stream sediments. Detailed surveys use closely spaced samples over an area of a few square kilometers, and individual samples may be as close as few meters apart.
What is a geochemical sample?
Geochemical sampling involves collecting and analyzing various earth materials such as rocks, soils, sediments, water, vegetation, and gasses. Various geochemical sampling methods have traditionally been some of the most efficient of any methods used in mineral ex- ploration.
What is a geophysics survey?
Archaeological geophysics Geophysical survey is a broad term covering the suite of detection methods used to map contrasts between the physical properties of buried archaeological remains and the surrounding soil.

What are geochemical methods?
Geochemical exploration is any method of mineral or petroleum exploration that utilizes systematic measurements of one or more chemical properties of a naturally occurring material. The materials analyzed most commonly are rock, soil, stream and lake sediment, natural waters, vegetation and soil air.
What are geochemical haloes?
A primary geochemical halo is an area of rocks surrounding mineral deposits (orebodies) enriched in ore-forming elements [2. N. I. Safronov, “Dispersion haloes of ore deposits and their use in exploration,” Problemy Sovetskoy Geologii, vol. 4, pp.

How does a geophysical survey work?
Geophysical surveys are ground-based physical sensing techniques that produce a detail image or map of an area. Ground-based surveys may include: Seismic surveys – vibrations from weights or explosives are recorded with geophones to provide information about the properties of rocks.
What is Halo geology?
A pleochroic halo, or radiohalo, is a microscopic, spherical shell of discolouration (pleochroism) within minerals such as biotite that occurs in granite and other igneous rocks. The halo is a zone of radiation damage caused by the inclusion of minute radioactive crystals within the host crystal structure.
