Geophysical methods of subsurface investigation involve using techniques such as seismic surveys, ground-penetrating radar (GPR), electrical resistivity, and magnetometry to study the properties of the subsurface without invasive digging. These methods can help identify underground structures, geologic features, water tables, and potential hazards. Geophysical investigations are commonly used in construction, environmental assessments, and resource exploration.

What are the geophysical methods for soil exploration techniques?

Geophysical methods for soil exploration include techniques like electrical resistivity, ground-penetrating radar (GPR), seismic refraction, and electromagnetic surveys. These methods are used to investigate the subsurface characteristics of soil and rock layers, map the depth and extent of geological features, and identify anomalies associated with potential hazards or resources. Geophysical surveys can help in environmental studies, engineering projects, and natural resource exploration.

Which of the following scientists build subsurface descriptions of discovered oilfields?

Petroleum geologists typically build subsurface descriptions of discovered oilfields by analyzing data such as rock samples, well logs, seismic surveys, and other geophysical data. They use this information to create detailed models of the underground formations and structures that contain oil and gas reserves.


How is surface mining similar to subsurface mining?

Surface mining and subsurface mining are both methods used to extract minerals from the Earth's crust. However, surface mining involves removing the overlying rock and soil to access the mineral resources, while subsurface mining involves digging tunnels or shafts underground to access the mineral deposits. Both methods can have environmental impacts and require careful planning and management to minimize these impacts.


What is geoelectric sounding for predicting aquifer properties?

Geoelectric sounding is a geophysical survey method that involves measuring the electrical resistivity of subsurface materials to infer properties such as water content and permeability. By analyzing variations in resistivity, geoscientists can infer the presence of aquifers, their extent, and potential water-bearing properties. This technique helps in understanding the subsurface characteristics and aids in groundwater exploration and management.

What Geophysical method for subsurface marble exploration?

Seismic reflection surveying is a commonly used geophysical method for subsurface marble exploration. By sending sound waves into the ground and recording their reflections, this method can help identify different rock layers, including marble, based on their acoustic properties. Other methods like ground-penetrating radar can also be used to locate marble deposits by detecting variations in subsurface materials.


What is an anomaly in geophysical exploration?

In geophysical exploration, an "anomaly" is simply a deviation from an expected geophysical background measurement. "Anomalies" can result either from a real, physical change in the subsurface, or can be the meaningless result from various kinds of "noise" internal to the geophysical equipment, or noise from external sources. When you're fortunate, an "anomaly" indicates the existence of, and some physical characteristics of, the thing or feature that you are actually attempting to detect.


Subsurface discontinuities can be detected by?

Subsurface discontinuities can be detected using various geophysical methods, such as ground-penetrating radar (GPR), seismic reflection and refraction, and electrical resistivity tomography. These techniques utilize the differences in physical properties between materials to identify changes in subsurface structures. Additionally, drilling and sampling may be employed to verify the presence and characteristics of these discontinuities.

How do geologists find out what's below earth's surface?

Geologists use several methods to explore what lies beneath the Earth's surface, including seismic surveys, which involve sending shock waves into the ground and analyzing their reflections to map subsurface structures. They also employ drilling techniques to extract rock and soil samples for analysis. Additionally, geophysical methods, such as magnetic and gravitational surveys, help identify the composition and density of underground materials. These techniques, combined with geological mapping and remote sensing, provide a comprehensive understanding of subsurface geology.
