This mineral, called chloritoid-3T, has a unique crystalline structure and can become an accurate \u201cgeothermometer.\u201d\u00a0<\/p>\n\n\n<p class=\"wp-block-paragraph\">A group of scientists from St. Petersburg State University, the Institute of Volcanology and Seismology, Far Eastern Branch of the Russian Academy of Sciences, and the Kola Science Center of the Russian Academy of Sciences studied chloritoid samples from the Urals. Using X-ray diffraction analysis, they identified a new type of crystal structure &#8211; chloritoid-3T.\u00a0<\/p>\n\n\n<p class=\"wp-block-paragraph\">This mineral differs from previously known varieties in its more ordered structure and high symmetry. Interestingly, it was found on the same <a data-id=\"https:\/\/geoconversation.org\/chto-meshaet-otkryvat-novye-mestorozhdeniya\/\" data-type=\"link\" href=\"https:\/\/geoconversation.org\/chto-meshaet-otkryvat-novye-mestorozhdeniya\/\">field<\/a>, where chloritoid was first discovered almost 200 years ago.\u00a0<\/p>\n\n\n<p class=\"wp-block-paragraph\">Chloritoids play a key role in geology:\u00a0<\/p>\n\n\n<ul class=\"wp-block-list\">\n<li>Allows you to determine the temperature (300-550\u00b0C) and pressure (2-10 atmospheres) of rock formation\u00a0<\/li>\n\n\n<li>Indicate the depth of occurrence (up to 30 km)\u00a0<\/li>\n\n\n<li>Help in <a data-id=\"https:\/\/geoconversation.org\/geohimiya-poisk\/\" data-type=\"link\" href=\"https:\/\/geoconversation.org\/geohimiya-poisk\/\">intelligence<\/a> minerals\u00a0<\/li>\n<\/ul>\n\n\n<p class=\"wp-block-paragraph\">The new 3T polytype will make these measurements more accurate. As Professor Andrey Zolotarev from St. Petersburg State University noted, the mineral is probably widespread, but previously went unnoticed due to diagnostic difficulties.\u00a0<\/p>\n\n\n<p class=\"wp-block-paragraph\">The research, supported by the Russian Science Foundation and published in American Mineralogist, opens up new possibilities for geologists.
