Country-shaped magnetic anomaly reveals buried geology beneath Northern Territory

Advanced modeling of magnetic data from Australia’s Northern Territory has uncovered a large magnetic anomaly shaped like the country, revealing buried geological boundaries and structures (faults, folds, basins) that conventional maps missed. Led by CSIRO researchers, the work refines the 1999 Bonney Well Survey data with a new gridding algorithm, producing clearer imagery and offering clues about Australia’s geological history and potential mineral resources, including hidden features exposed at the surface in the Hatches Creek Formation dating to 2.5–1.6 billion years ago.

"Uncovering a Magnetic Anomaly Beneath New Zealand's Lake Rotorua"

Detailed maps of Lake Rotorua in New Zealand have uncovered hidden subsurface features, including hydrothermal explosion craters, traces of an old river, and a significant magnetic anomaly in the lake's southern section. GNS Science researchers used various measurement techniques to probe beneath the lake's surface, revealing the presence of hydrothermal activity and pinpointing active regions.

"Uncovering a Magnetic Anomaly Beneath Lake Rotorua in New Zealand"

New maps have revealed a hidden hydrothermal system beneath New Zealand's Lake Rotorua, located in the crater of a dormant volcano. The maps, created by researchers at GNS Science, show eruption craters, an ancient river, and a large magnetic anomaly in the lake's southern part, indicating that the mainland hydrothermal systems extend into the lake's depths. The anomaly is likely due to hydrothermal fluids transforming highly magnetic minerals into fool's gold, severely diminishing the magnetic signal. Despite this activity, water temperatures near the lake's bottom remain cool due to the large size of the lake.

Mysterious Magnetic Anomaly Found in Mesopotamian Bricks

Scientists studying Mesopotamian bricks have discovered traces of a magnetic anomaly from the Levantine Iron Age, shedding light on the strength of Earth's magnetic field 3,000 years ago. By subjecting the bricks to extreme heat and comparing the original magnetic field with a recreated one, researchers were able to date the bricks and develop a new technique for dating ancient artifacts. This innovative method may revolutionize the field of archeology and provide insights into the periodic peaks of Earth's magnetic field throughout history.

NASA Investigates Mysterious Lunar Magnetic Anomaly with Advanced Spectrometer

NASA is investigating an unexplained magnetic anomaly on the Moon's nearest-facing side using a next-generation plasma spectrometer called the Magnetic Anomaly Plasma Spectrometer (MAPS). Developed by Southwest Research Institute (SwRI), MAPS will be incorporated into NASA's Lunar Vertex lander for the upcoming Lunar Vertex investigation. The spectrometer will study the interaction between the solar wind and the Moon's surface materials, particularly in the Reiner Gamma region, which produces a localized magnetic field. MAPS aims to understand the influence of the magnetic anomaly on the solar wind and provide insights into the Moon's formation and evolution.
