The magnetism of rocks, ores and geological structures in nature is uneven. Under the geomagnetic field, the magnetic inhomogeneity will cause the spatial distribution of the geomagnetic field to change. The magnetic field of magnetic bodies is superimposed on the normal geomagnetic field, and this superimposed magnetic field is called magnetic anomaly. By detecting magnetic anomalies with proton precession magnetometer, the distribution of magnetic ore bodies and geological structures can be inferred.
After compaired with other proton magnetometers, Geomative has spent two years developing a new generation proton magnetometer. It’s light and portable. It uses a thermostatic crystal oscillator(OCXO) with high accuracy and stability to make it more stable.
Standard GPS supports GNSS, GPS, Beidou and GLONASS systems, which provides location and accurate time synchronzation. The time synchronization accuracy reachs 30 ms, which is more convenient to use.
It supports mobile, walk or base station mode. It is mainly applied in minerals exploration (such as iron ore, lead-zinc ore,copper ore, etc.), geophysical exploration in geological structures, archaeology, earthquake, volcanic activity research and long-term geomagnetic measurement stations.
Light and portable, the whole system uses a backpack strap, and one person can complete all measurement tasks
With USB flash disk transmission and RS-232 transmission, two data transmission mode
Professional geological software can draw contour maps, profiles maps, etc.
32MB memory,support modifying
1.It can measure the total field of the geomagnetic field or the gradient measurement (horizontal gradient or vertical gradient, need to add probe and probe holder)
2.Using walking MAG acquisition mode can collect mag netic field data while walking in the field, so as to obtain continuous observation profiles
3.External GNSS, no need to configure baudrate. It can be used to store the coordinate values of the measuring points, and at the same time, the proton magnetometer is time synchronized, and the time synchronization accur acy reaches 30 microseconds
4.Built-in high-precision constant temperature crystal oscillator not only ensures measurement accuracy, but also ensures measurement stability
5.It can display the magnetic field strength curve, easy to operate and intuitive data
6.Can move single point measurement and move continuous measurement
