What are the geophysical instruments for detecting geological structures?

Geophysical instruments for detecting geological structures include the following:

Instrument: An instrument used to measure waves, which can understand the structure and geological structure of the earth's crust.

Gravimeter**: Measure changes in the Earth's gravity to help determine the location of geological formations and mineral resources.

Magnetometer**: Measure changes in the Earth's magnetic field to help find magnetic minerals and geological formations.

Resistance Meter**: Measure the resistivity of formations, which is helpful in determining the location of groundwater and oil and gas reservoirs.

Sonograph**: Measure the velocity of sound waves in a formation to understand the physical properties and geological structure of the formation.

Radiometers**: Measure radioactive elements in formations and rocks to help find radioactive minerals such as uranium.

These geophysical instruments can be used in combination to more accurately determine the location of geological formations and mineral resources.

This is usually the specific method first.

Small-scale area structure mapping generally uses gravity and magnetic methods (gravimeter and magnetometer), and sometimes **.

Large-scale methods such as gravity, magnetism, electricity, and ** (corresponding to gravimeter, magnetometer, electric method and ** instrument). Among them, there are many branches of electrical method, such as high-density electric method, transient electromagnetic method, electromagnetic sounding, IP sounding, etc., and there are many corresponding instruments. Even the same method, such as magnetic instruments, can be used in many varieties (both domestic and imported).

1. Measuring instruments, such as GPS satellite positioning instruments, are fixed.

2. Instruments for exploration and collection, such as ** collection instrument vehicles, cables and small wires for collecting ** waves.

3. The collection and receiving station, the small line and the receiving station are connected to the cable, Xu Hutong multi-cable is connected to the instrument car with a connecting line, and the explosives are used to go down to the underground cannon to produce the first wave, and the computer receiving system of the instrument car can receive the first wave.

Geological radar, or GPR for short, is a geophysical survey technology that uses the principle that high-frequency electromagnetic waves are sensitive to the electrical difference between the target material and the surrounding material to detect underground objects. Ground penetrating radar technology is a high-precision, high-resolution, and high-efficiency nondestructive testing technology that has developed rapidly in recent years, and is one of the most active technologies in the fields of engineering inspection, geotechnical engineering, and survey and design [3]. Its main applications are as follows:

1. Application in the field of water conservancy and hydropower: used for site selection investigation of dam projects and exploration of engineering hidden dangers, and successfully applied to river bank slope collapse investigation, dam crack investigation, animal burrow exploration, dam foundation investigation, leakage investigation, etc.

2. Application in the field of geological engineering geotechnical investigation: mainly used for building foundation treatment, foundation investigation, slope stability investigation, bedrock surface detection, karst cave goaf investigation, foundation tamping detection, geological structure disaster, groundwater detection, etc.

3. Application in the field of mining engineering: used to detect goaf, collapse area, fault fragmentation zone, seepage area, surrounding rock loosening and stope filling investigation, etc.

4. Application in the field of airport highway tunnels: quality inspection and disease diagnosis of airport highway tunnels, 5. Application in scientific research fields such as archaeological glacial environment: mainly used for underground tomb exploration, glacier thickness investigation, garbage burial body investigation, etc.

1.Archaeology, prospecting, and the discovery of gold and silver treasures and metal artifacts buried underground. It is equipped with a ground balance line, which can eliminate the influence of "mineralization reaction", and greatly improve the depth and accuracy of effective blind leakage detection; 2.It has the function of grinding bridge to distinguish ferrous metals from non-ferrous metals;

3.Adopt an intelligent operating system;

4.It is packaged with high-strength ABC material, which is light in weight and has a long life.

5.Metallic sounds can be recognized by headphones.

Instruments used in geological work to collect, store, identify, and process geological information, and to explain and infer geological phenomena.

It is an instrument used to collect, store, identify, and process geological information, and to explain and infer geological phenomena in geological work. The scope of geological information is extremely wide-ranging. The macro aspects include tectonics, topography, landforms, strata, geophysical fields, various physical parameters of rocks and minerals, and the content and distribution of chemical elements in soil and water. The microscopic aspect includes the material composition, structure and evolution characteristics of the light sheets and thin sections of rocks and minerals under the microscope, and the fission tracks of elements.
