The three-dimensional model they created revealed a gigantic geological structure beneath the surface of the northern territory of the continent, whose contours surprisingly resemble the outlines of the continent itself.<\/p>\n\n\n<p class=\"wp-block-paragraph\">This discovery, informally called the Australian Magnetic Anomaly, was made possible thanks to an innovative algorithm for reprocessing archival data. Specialists from the national scientific agency CSIRO re-analyzed the results of a large-scale <a data-id=\"https:\/\/geoconversation.org\/gravitacziya-vertolety-i-gory-ili-chto-my-delali-na-yukone-etim-letom\/\" data-type=\"link\" href=\"https:\/\/geoconversation.org\/gravitacziya-vertolety-i-gory-ili-chto-my-delali-na-yukone-etim-letom\/\" rel=\"noopener\" target=\"_blank\">aeromagnetic survey<\/a>conducted more than twenty years ago.<\/p>\n\n\n<p class=\"wp-block-paragraph\">A new computational approach made it possible to eliminate interference and \u201creveal\u201d previously hidden details. As the researchers explain, rocks have a kind of mineral memory, recording the direction and strength of the planet\u2019s magnetic field at the time of their formation. Deciphering these records opens a window into Earth&#8217;s deep past.<\/p>\n\n\n<p class=\"wp-block-paragraph\">The improved model for the first time clearly showed the complex internal architecture of the region: previously indistinguishable strata, deep faults and folded structures. It has been established that the western edge of this large-scale anomaly is exposed on the surface in the area of \u200b\u200b\u200b\u200bthe ancient Hatches Creek Formation, whose age is estimated at 1.6\u20132.5 billion years.<\/p>\n\n\n<p class=\"wp-block-paragraph\">This research not only reveals new chapters in Australia&#8217;s geological history, but also demonstrates the power of modern <a data-id=\"https:\/\/geoconversation.org\/kak-najti-litijsoderzhashhie-pegmatity-nazemnoj-gravirazvedkoj\/\" data-type=\"link\" href=\"https:\/\/geoconversation.org\/kak-najti-litijsoderzhashhie-pegmatity-nazemnoj-gravirazvedkoj\/\" rel=\"noopener\" target=\"_blank\">geodata interpretation methods<\/a>.
