Not in glittering nuggets or chunky veins, but in forms so small and hidden that you can\u2019t see them with your eyes\u2014or even with a regular microscope.<span class=\"id-r-component br\" data-pos=\"4\"\/>Japanese researchers have been studying this submerged volcanic crater, known as the Higashi\u2011Aogashima caldera, and what they\u2019ve found sounds like something out of a science fiction story: \u201cblack smoker\u201d chimneys and hydrothermal mounds that are actively forging vast quantities of gold, much of it locked away inside other minerals on the seafloor.<span class=\"id-r-component br\" data-pos=\"6\"\/>This is a story about invisible treasure, restless geology, and a difficult question: how do we treat places that are rich in resources, but still largely unknown to science and untouched by industry?<span class=\"id-r-component br\" data-pos=\"8\"\/><\/p>\n<p><h2>A volcano under the waves, and chimneys that smoke black<br \/><\/h2>\n<\/p>\n<p>Hydrothermal vents are places where super\u2011hot, mineral\u2011rich water gushes out of the seafloor, usually around volcanic activity. <!-- -->At Higashi\u2011Aogashima, these vents form towering structures called \u201cblack smoker\u201d chimneys. They look like underwater stacks belching dark, plume\u2011like clouds\u2014but the \u201csmoke\u201d is actually tiny particles of metals and minerals, blasted into cold ocean water.<span class=\"id-r-component br\" data-pos=\"14\"\/>Here, that mineral mix includes gold.<span class=\"id-r-component br\" data-pos=\"16\"\/>Over time, these vents build mounds and chimneys, layer upon layer, as hot fluid keeps depositing material. Japanese researchers from Shizuoka University, Waseda University and the University of Tokyo have been collecting rocks from this underwater field, around 350 kilometres south of Tokyo, to understand exactly what\u2019s being formed down there.<span class=\"id-r-component br\" data-pos=\"19\"\/>What they found changed the way we think about gold in the deep sea.<span class=\"id-r-component br\" data-pos=\"21\"\/> <\/p>\n<div data-pos=\"0\" class=\"id-r-component iIpbx undefined  &#10;        \">\n<div><img decoding=\"async\" alt=\"Representative image\" msid=\"132468667\" width=\"\" title=\"\" placeholdersrc=\"https:\/\/static.toiimg.com\/photo\/83033472.cms\" imgsize=\"\" resizemode=\"4\" offsetvertical=\"0\" placeholdermsid=\"47529300\" type=\"thumb\" class=\"\" src=\"https:\/\/static.toiimg.com\/photo\/msid-132468667\/representative-image.jpg\" data-api-prerender=\"true\"\/><\/div>\n<\/div>\n<p><span class=\"id-r-component br\" data-pos=\"24\"\/><\/p>\n<p><h2>Not all gold shines<\/h2>\n<\/p>\n<p>When most of us imagine gold, we think of something shiny: jewellery, coins, or at least small flakes catching the light. The gold at Higashi\u2011Aogashima is very different.<span class=\"id-r-component br\" data-pos=\"27\"\/>Using an extremely sensitive technique called secondary\u2011ion mass spectrometry (SIMS), the scientists discovered that the seafloor chimneys and mounds contain \u201cinvisible gold\u201d\u2014gold that\u2019s present in quantities far too small to reflect light in a way we can see.<span class=\"id-r-component br\" data-pos=\"30\"\/>This hidden gold is wrapped inside a mineral called pyrite.<span class=\"id-r-component br\" data-pos=\"32\"\/>Pyrite is a sulfide mineral with a metallic, yellowish sheen. Because it looks a bit like gold at a glance but isn\u2019t, it\u2019s nicknamed \u201cfool\u2019s gold.\u201d In these hydrothermal vents, pyrite forms when hot, metal\u2011rich fluids erupt from the seafloor and meet colder seawater. As the fluid cools, minerals crystallise and grow.<span class=\"id-r-component br\" data-pos=\"34\"\/>Inside those crystals, the team found real gold in two main forms:<span class=\"id-r-component br\" data-pos=\"36\"\/>As tiny nanoparticles embedded within the pyrite.<span class=\"id-r-component br\" data-pos=\"39\"\/>As individual gold atoms incorporated into the mineral\u2019s crystal structure itself.<span class=\"id-r-component br\" data-pos=\"41\"\/>Under normal conditions, you\u2019d never know it was there. But with the right tools, the researchers could see that these pyrite grains aren\u2019t just imposters\u2014they\u2019re carrying some of the richest gold concentrations ever recorded anywhere in the world.<span class=\"id-r-component br\" data-pos=\"43\"\/><\/p>\n<p><h2>The richest invisible gold yet<\/h2>\n<\/p>\n<div data-pos=\"0\" class=\"id-r-component iIpbx undefined  &#10;        \">\n<div><img decoding=\"async\" alt=\"Representative image\" msid=\"132468648\" width=\"\" title=\"\" placeholdersrc=\"https:\/\/static.toiimg.com\/photo\/83033472.cms\" imgsize=\"\" resizemode=\"4\" offsetvertical=\"0\" placeholdermsid=\"47529300\" type=\"thumb\" class=\"\" src=\"https:\/\/static.toiimg.com\/photo\/msid-132468648\/representative-image.jpg\" data-api-prerender=\"true\"\/><\/div>\n<\/div>\n<p><span class=\"id-r-component br\" data-pos=\"47\"\/>When the scientists measured the amount of gold hidden in the pyrite from Higashi\u2011Aogashima, they realised they were looking at something extraordinary. <!-- -->The concentration of this invisible gold is higher than any previously documented site on Earth.<span class=\"id-r-component br\" data-pos=\"51\"\/>Add to that the fact that this underwater crater is relatively shallow compared to many other deep\u2011sea vent systems, and it becomes clear why the area has caught the attention of more than just geologists. In practical terms, shallower depths make potential mining or resource extraction easier and cheaper to access than vents located in the deep ocean.<span class=\"id-r-component br\" data-pos=\"54\"\/>So you have:<span class=\"id-r-component br\" data-pos=\"56\"\/>&#8211; A site within Japan\u2019s exclusive economic zone.<span class=\"id-r-component br\" data-pos=\"58\"\/>&#8211; Exceptionally high concentrations of gold in seafloor minerals.<span class=\"id-r-component br\" data-pos=\"60\"\/>&#8211; A vent system that is relatively accessible compared to many others.<span class=\"id-r-component br\" data-pos=\"62\"\/>From an industrial perspective, that sounds like the beginnings of a future gold mine.<span class=\"id-r-component br\" data-pos=\"64\"\/>But the scientists studying Higashi\u2011Aogashima are also sounding a cautious note.<span class=\"id-r-component br\" data-pos=\"66\"\/><\/p>\n<p><h2>Treasure vs. life: A complicated balance<\/h2>\n<\/p>\n<p>Right now, there is no commercial gold mine operating on the ocean floor anywhere in the world. <!-- -->However, sites like Higashi\u2011Aogashima are increasingly being discussed as future candidates for seabed mining, especially as countries explore new ways to secure mineral resources.<span class=\"id-r-component br\" data-pos=\"71\"\/>The problem is: we barely know what lives there.<span class=\"id-r-component br\" data-pos=\"73\"\/>Hydrothermal vent fields often host unique ecosystems. Many are home to specialised animals\u2014tube worms, shrimp, crabs, and microbes\u2014that thrive in hot, mineral\u2011rich waters and may not survive anywhere else. <!-- -->The Higashi\u2011Aogashima vents were first discovered in 2015, and scientists still don\u2019t have a clear picture of how much and what kind of marine life these fields support.<span class=\"id-r-component br\" data-pos=\"77\"\/>That\u2019s why, alongside the excitement of finding record\u2011breaking concentrations of invisible gold, researchers and international experts are urging caution. An international team has already warned that active seafloor mounds like these need protection from commercial mining interests, at least until we understand the ecosystems they support and the long\u2011term consequences of disturbing them.<span class=\"id-r-component br\" data-pos=\"80\"\/>Tearing apart vent structures to extract minerals wouldn\u2019t just remove gold. It would disrupt habitats built up over years, possibly wiping out species that we haven\u2019t even documented yet.<span class=\"id-r-component br\" data-pos=\"82\"\/><\/p>\n<p><h2>The technical challenge: How do you extract what you can\u2019t see?<br \/><\/h2>\n<\/p>\n<p>Even if we put the ecological questions aside for a moment, there\u2019s a practical challenge: recovering \u201cinvisible gold\u201d is not straightforward.<span class=\"id-r-component br\" data-pos=\"85\"\/>Unlike traditional mining, where gold can be physically separated from rock once crushed and processed, here the gold is either:<span class=\"id-r-component br\" data-pos=\"87\"\/>Locked inside microscopic particles of pyrite.<span class=\"id-r-component br\" data-pos=\"90\"\/>Present as individual atoms inside the crystal lattice of the mineral.<span class=\"id-r-component br\" data-pos=\"92\"\/>To get it out would require methods that can efficiently concentrate and extract gold at very fine scales from huge volumes of seafloor material\u2014and do so economically. At present, scientists are still working out how this could be done in a way that makes financial sense, let alone environmental sense.<span class=\"id-r-component br\" data-pos=\"94\"\/>In other words, the gold is there\u2014but turning it into something you can hold or sell is a non\u2011trivial problem.<span class=\"id-r-component br\" data-pos=\"97\"\/><\/p>\n<p><h2>A reminder about the unseen world beneath the waves<\/h2>\n<\/p>\n<p><span class=\"id-r-component br\" data-pos=\"99\"\/>What makes this discovery feel so human, beyond the technical details, is what it says about our relationship with the deep sea.<span class=\"id-r-component br\" data-pos=\"101\"\/>For most of us, the ocean floor is invisible and abstract\u2014a map on a screen, a depth number, an idea. Yet down there, volcanoes are still active, minerals are still forming, and life is quietly adapting to conditions we can hardly imagine. In the glow of a hydrothermal vent, \u201cfool\u2019s gold\u201d becomes a hiding place for some of the purest gold known. <!-- -->In the shadow of mining plans, scientists are trying to understand ecosystems that may depend on those chimneys to exist at all.<span class=\"id-r-component br\" data-pos=\"105\"\/>The story of Higashi\u2011Aogashima is not just about hidden wealth. It\u2019s about perspective. It asks us to consider:<span class=\"id-r-component br\" data-pos=\"108\"\/>&#8211; How much we\u2019re willing to disrupt in order to gain access to new resources.<span class=\"id-r-component br\" data-pos=\"110\"\/>&#8211; How little we still know about the living communities tied to these strange, beautiful places.<span class=\"id-r-component br\" data-pos=\"112\"\/>&#8211; How our technological reach is racing ahead of our understanding.<span class=\"id-r-component br\" data-pos=\"115\"\/>Somewhere off Japan\u2019s coast, black smoker chimneys are quietly forging gold no one can see. The question isn\u2019t just whether we can get to it\u2014it\u2019s whether, and how, we should.<span class=\"id-r-component br\" data-pos=\"117\"\/>When you think about this underwater \u201cgold factory,\u201d what feels more striking to you\u2014the idea of so much hidden value locked inside fool\u2019s gold, or the uncertainty about what might be lost if we rush to claim it?<span class=\"id-r-component br\" data-pos=\"119\"\/><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/timesofindia.indiatimes.com\/science\/scientists-discover-record-breaking-invisible-gold-forming-inside-underwater-volcano-off-japan\/articleshow\/132468595.cms\" target=\"_blank\" rel=\"noopener\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Far below the surface of the Pacific, off the southeastern coast of Japan, there\u2019s a place where the Earth is quietly minting gold.
