Proton Precession Magnetometer vs Proton Magnetometer
TIPS：In geophysical exploration and archaeological research, Proton Precession Magnetometer (PPM) and Proton Magnetometer represent two distinct technical approaches. This article thoroughly analyzes their operational principles: PPM achieves high-precision absolute measurements (±0.1nT accuracy) by detecting the Larmor precession frequency of protons…
Geomagnetic Surveying: Unlocking the Earth’s Magnetic Field
In the vast field of geophysical exploration, geomagnetic surveying is emerging as a powerful tool for unlocking the mysteries of the Earth’s magnetic field. This article delves into the principles, applications, and latest developments of geomagnetic surveying. I. Principles and…
Electrical Resistivity Tomography: A Powerful Tool for Geophysical Exploration
What is Electrical Resistivity Tomography? Electrical Resistivity Tomography (ERT), a cutting-edge geophysical technique, has revolutionized subsurface imaging. It measures how well subsurface materials resist electrical currents, creating detailed 2D and 3D images of geological structures. These images help scientists and…
