Geology
Geology is divided into several fields that can be grouped under the main headings of physical and historical geology.
Applied Geology
Applied Geology is geologic knowledge to solving geologic problem. In other words, application of various fields of geology to economic, engineering, water-supply, or environmental problems; geology related to the human activity.
METHODS OF GEOLOGY
Geologists use primary data associated with petrology (the study of rocks), stratigraphy (the observe of sedimentary layers), and structural geology (the have a look at of positions of rock devices and their deformation). In many cases, geologists additionally take a look at contemporary soils, rivers, landscapes, and glaciers; inspect past and contemporary life and biogeochemical pathways, and use geophysical techniques to investigate the subsurface.
Electromagnetic (EM) Methods
Electromagnetic methods in geophysics involve the use of electromagnetic fields to study the subsurface properties of the Earth. These methods exploit the interaction between...
Ground-Penetrating Radar (GPR)
Ground-Penetrating Radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-destructive technique that allows the visualization...
Electrical Resistivity Surveys
Electrical resistivity surveys are geophysical techniques used to measure the subsurface electrical resistivity of soils and rocks. The method involves injecting an electrical current...
Magnetic Surveys
Magnetic surveys are a geophysical exploration technique used to measure and map variations in the Earth's magnetic field. The Earth's magnetic field is not...
The Seismic Method
The seismic method is a crucial technique in geophysics that plays a significant role in understanding the subsurface structure of the Earth. It is...
