New maps of Australia have helped scientists identify a previously unknown magnetic anomaly beneath the country's Northern Territory. This discovery will allow us to better understand the geological history of the continent, especially the formation of different rock layers.
Magnetic anomalies are localized changes in the Earth's magnetic field due to the properties of certain minerals and rocks. Research has shown that the Australian site has faults, folds and depressions that cannot be detected by traditional mapping methods.
The team of scientists used advanced modeling techniques. The planes, equipped with magnetometers, flew over the Northern Territory on flat routes about 400 meters apart.
By analyzing the data collected, scientists identified thin magnetic layers, as well as hidden geological boundaries and structures that had not been discovered in previous maps. The work of interpreting the data is not yet complete. But it is known that the western limit of the magnetic anomaly occurs at the surface in the Hatches Creek Formation in the Northern Territory. This geological feature consists of sandstone and volcanic rocks that are 2.5-1.6 billion years old. Scientists note that mapping magnetic anomalies could lead to important discoveries, such as new mineral deposits, Live Science reported.
Previously, scientists offered a new explanation for the mystery of the Bermuda Triangle. The disappearance of ships and planes may be linked to methane emissions. But now that they have stopped, there are significantly fewer reports of mysterious disappearances in this area.
