Fossil fuels, ore and industrial minerals

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">First occurrence of xenotime-(Y) veins in the Neoproterozoic metamudstone, NW margin of the Małopolska Block, is reported here. The veins are &lt;5 μm thick, inhomogeneous and of varied morphology. Their textural characteristics, exhibiting very low U and Th contents (&lt;1 wt%) and relatively high heavy rare earth elements (REE) contents (12-24 REE2O3 wt%), suggest hydrothermal genesis, though diagenetic precursors of the veins are not excluded. The veins provide good evidence of the mobility of Y, REE, U and Th in low-temperature conditions (anchimetamorphic to greenschist facies). The observed differences in the chemical composition of the veins may indicate multiple stages of formation, possibly during several hydrothermal events that affected the area.</abstract>

Xenotime-(Y) veins in a Neoproterozoic metamudstone (Małopolska Block, S Poland)

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">An unusual association of Se minerals was studied. Se enters into the structures of sulphosalts - into bournonite, jamesonite and tintinaite at concentrations up to 0.10, 0.38 and 1.11 apfu, respectively. However, Se and Te, together with Bi, also form discrete minerals such as tetradymite, laitakarite, ikunolite and hedleyite. Members of the laitakarite-ikunolite solid solution display a wide range of anion substitution from the nearly Se-free (0.10 apfu) end member to the S-poor (0.42 apfu) end member. Their contents of Te are low. Accompanying tetrahedrite does not contain Se or Te.</abstract>

Bi-Se-Te mineralization from Úhorná (Spišsko Gemerské Rudohorie Mts., Słovakia): A preliminary report

<abstract xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">In 1802, Leopold von Buch described some outcrops of orbicular granite in the Karkonosze granite, Lower Silesia, Poland. In that publication, Abraham Gottlieb Werner wrote a foreword dated 1800. The Silesian discovery predates that of the well-known orbicular diorite (Napoleonite) in outcrop on Corsica and, thus, may be the first ever record of this distinctive rock type in its geological context. The characterizing, closely-packed, simple orbs comprise K-feldspar cores surrounded by rims of radiating K-feldspar and quartz. Rapid growth from a hydrous, pegmatitic melt is indicated. The Karkonosze outcrop, in the timing of its discovery, is a unique part of the geological heritage.</abstract>

Mineralogia

 Mineralogia (ISSN: 1899-8291, e-ISSN: 1899-8526), a free open access journal, publishes original research and review papers from broad fields of geochemistry, mineralogy, petrology, technical, experimental and applied mineralogy, and environmental sciences. Mineralogia (formerly Mineralogia Polonica) is an English language journal with 50 years long tradition. The journal’s subtitle, Geochemical, Mineralogical and Petrological Research, indicates the open character of the journal. The regular series Mineralogia is accompanied by the irregular series, including Mineralogia - Special Papers (containing conference abstracts) and Thematic Collections.    Publications in the scope of widely understood mineralogical sciences (mineralogy, petrology, geochemistry, environmental sciences, applied mineralogy, etc.)   Original research and review papers, letters (a short research paper), short notes (a brief communication), book reviews, and letters to editors with comments on papers published in Mineralogia    First issue of Mineralogia Polonica, the official Journal of the Mineralogical Society of Poland, was published in 1970 soon after foundation of the Society in 1969. Mineralogia Polonica, publishing in English from its beginning, has been very important for development of mineralogical sciences in Poland, exchange of scientific journals and international collaboration. Based on a long discussion with our colleagues from abroad we have noticed that the title suggests that the journal is focused on local mineralogical problems from Poland. To avoid this misunderstanding we have decided to modify the title and accordingly the journal cover. The new and simple title Mineralogia (with subtitle Geochemical, Mineralogical and Petrological Research) indicates an open character of the journal. We intend to publish original papers, review papers and short notes from broad fields of geochemistry, mineralogy, petrology, technical, experimental and applied mineralogy, environmental geochemistry and mineralogy. We have also decided to introduce changes in the organization of our Editorial Board to ensure high scientific level of journal and relatively short time-span between paper submission and publication.   The journal facilitates communication and promotes scientific research in the scope of:    descriptive mineralogy   experimental mineralogy   igneous petrology   metamorphic petrology   sedimentary petrology   hard rock geochemistry   geochronology and petrochronology   environmental mineralogy and geochemistry    Why subscribe and read    excellent source of outstanding interdisciplinary research papers in mineralogy, petrology, geochemistry and related disciplines;   over fifty years of publishing;   offers high-quality electronic publications (eISSN 1899-8526);   special issues publishing reviewed abstracts from conferences co-organized by the Mineralogical Society of Poland;    Why submit    fast, fair, and constructive single-blind peer review and editing;   no processing and no publication charges;   language-correction services for authors from non-English speaking regions;      Archiving   Sciendo archives the contents of this journal in Portico - digital long-term preservation service of scholarly books, journals and collections.   Plagiarism Policy   The editorial board is participating in a growing community of Similarity Check System's users in order to ensure that the content published is original and trustworthy. Similarity Check is a medium that allows for comprehensive manuscripts screening, aimed to eliminate plagiarism and provide a high standard and quality peer-review process.   Funding   Authors should list all funding sources in the Acknowledgments section.   ORCID   Mineralogia journal requires ORCID.   Ethical considerations   This journal follows the basic principles of the publishing process as documented by the Committee on Publication Ethics (COPE). The COPE’s guidelines focus mainly on issues related to publication in the medical literature; thus, not all the points are relevant to the Mineralogia journal. Although the essential ethical concerns considered while publishing in Mineralogia align with the COPE guidelines, Mineralogia is not bound by their defined processes.   Mineralogia otrzymała dofinansowanie z MNiE na lata 2022-2024 w ramach programu Rozwój czasopism naukowych (RCN/SN/0190/2021/1).   Ministry of Science and Higher Education co-financed Mineralogia in 2022-2024 as part of the Development of Scientific Journals call (Rozwój czasopism naukowych; RCN/SN/0190/2021/1).
