The UNEXMIN (Horizon 2020) and UNEXUP (EIT RawMaterials)projects developed a novel technology to send robots and even autonomouslydeliver optical images, 3D maps and other georeferenced scientific data fromflooded underground environments, like abandoned mines, caves or wells.

Late to postmagmatic metasomatic processes involve the enrichment of volatile components such as boron and halogens as well as several metallic elements. The purpose of this study is to reveal the main metasomatic effects and paragenetic sequences of the related mineralizations in Highiş granitoids, Romania. In a natural outcrop, more than 30 samples were collected from granitoids, felsic veins, and country rocks. We carried out a detailed mineralogical and petrological characterization of carefully selected samples using X-ray powder diffractometry, electron microprobe analysis, and microscopic methods together with K–Ar ages of whole rocks and K-bearing minerals. Several characteristic features of albitization, sericitization, tourmalinization, epidotization, and hematitization were recognized in the studied samples. Crystallization of quartz, K-feldspar, and magnetite represents the first stage during the magmatic-hydrothermal transition. The mineral assemblage of albite, sericite, schorl, and quartz originates from the early and main stages of greisenization. While the subsequent mineral assemblages, which predominantly include dravite, specular hematite, and epidote, are closely related to the late vein-depositing stage. We propose that the study area could belong to a boron-rich open greisen system in the apical portion of Guadalupian A-type granite. Based on a new hypothesis, the previously published Permian crystallization ages (between ~272 Ma and ~259 Ma) could be homogenized and/or partially rejuvenated during the hydrothermal mineralization processes due to uraniferous vein minerals. Additionally, the Highiș granite-related system suffered a Cretaceous thermal overprint (between ~100 Ma and ~96 Ma). The results may help to understand the evolution of highly evolved granite intrusions worldwide and improve our knowledge of the effect of hydrothermal mineralization processes on the emplacement ages.}, year = {2023}, eissn = {2075-163X}, orcid-numbers = {Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482; Topa, Boglárka Anna/0000-0003-1996-2261; Pál-Molnár, Elemér/0000-0002-9606-0133; Raucsik, Béla/0000-0002-1951-5974} } @article{MTMT:33821788, title = {Uranium isotope evidence for extensive seafloor anoxia after the end-Triassic mass extinction}, url = {https://m2.mtmt.hu/api/publication/33821788}, author = {Somlyay, Anna and Palcsu, László and Kiss, Gabriella Ilona and Clarkson, Matthew O. and Kovács, Emma Blanka and Vallner, Zsolt and Zajzon, Norbert and Pálfy, József}, doi = {10.1016/j.epsl.2023.118190}, journal-iso = {EARTH PLANET SC LETT}, journal = {EARTH AND PLANETARY SCIENCE LETTERS}, volume = {614}, unique-id = {33821788}, issn = {0012-821X}, year = {2023}, eissn = {1385-013X}, orcid-numbers = {Somlyay, Anna/0000-0002-7567-5251; Kovács, Emma Blanka/0000-0003-0854-4347; Zajzon, Norbert/0000-0003-4664-8091; Pálfy, József/0000-0001-9686-1849} }
