The natural vibrations of the crystal lattice of these minerals are predominantly inactive in the infrared spectrum, which complicates their identification. Rutile is proposed to be determined by the absorption band ~ 1062 cm-1; and cassiterite, by the lines 1059–1065, ~ 1130, 1217–1220, and 1366–1373 cm-1. The characteristic absorption bands in the region of 3200–3400 cm-1, associated with vibrations of OH defects in the crystal lattice of these minerals, have been shown to be of particular importance for the diagnosis of rutile and cassiterite. Structural hydroxyl groups in the spectra are manifested in rutile by a line at about 3279–3283 cm-1; and in cassiterite, by lines at about 3254–3259 cm-1, ~ 3343 and ~ 3377 cm-1.","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":" September","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141669666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A peculiarity of this object is the presence of rare-earth mineralization in the ores. The main REE concentrator minerals include monazite, allanite, apatite, and epidote. One of the main concentrators of REE is apatite, where the content of REE sum reaches 2.6 wt. %. The REE are mainly represented by light lanthanides, with La up to 1.8 wt. % and Ce up to 2.08 wt. % predominating. Monazite- (Ce) is formed in the process of apatite refining, leading to the monazite fine-grained dissemination and veinlets occurring. Epidote is found in nests and vein-like formations of skarn aggregates. The mineral mainly contains light lanthanides (La up to 5.11 wt. %, Ce up to 2.47 wt. %) and forms gradual transitions to allanite that, in its turn, is also found in the form of isolated segregations or as a part of aggregates of epidote-allanite composition. Light lanthanides with Ce up to 14.35 wt. % and La up to 9.16 wt. % pre-dominate in the allanite composition. The study of the mineral composition and distribution of REE in ores and minerals allows us to conclude that rare-earth mineralization in the ores of the Gurvunur apatite-magnetite deposit was formed as a result of skarning of the carbonate-bearing volcanogenic-sedimentary rocks, and the source of rare-earth mineralization was granodiorites of the Vitimkan intrusive suite.","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":"124 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141667694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ore mineralization is assigned to the gold-sulfide-quartz vein and gold-sulfide types. We determined a wide range of ore-forming elements, associated with gold in pyrite. These elements correspond to geochemical features of the late galena-chalcopyrite-sphalerite mineral assemblage of the ore process, as well as to its final stage expressed in the appearance of elements reflecting the mineralogy of gray ores and bismuth sulfosalts. Pyrites from the vein and mineralized zones, from the ores of the deposit and from the secondary lithochemical anomalies, were found to contain the same set of the gold satellite elements: Ag, Cu, Zn, Pb, As. In pyrite of the gold-sulfide-quartz veins, Au has close correlations with the main elements of the ore association. In pyrite of the mineralized zones, all the correlations between Au and the ore-forming elements are absent. The pair-wise correlation between the ore-forming elements in these zones also changes completely. It is demonstrated that the identified differences in correlations between Au and the ore-forming elements in pyrite are a criterion for assessment of the lithochemical anomalies and allow one to propose a strategy of prospecting for new ore objects in the Manitanyrd region.","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":" 833","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141669223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The porphyry-type mineralization is associated with the Priokhotsky plutonic belt of Albian-Cenomanian granitoids of the Magadan suite of the calcareous-alkaline series (K/Na <1). The granitoids are dominated by porphyritic tonalites and quartz diorites of type I magnetite series, often adakitic in composition. The mineralization is accommodated by the Jurassic-Lower Cretaceous island-arc sedimentary-volcanic formations. Relationship between the mineralization and granitoids is substantiated by the U-Pb SIMS SHRIMP and Re-Os TIMS dating. In potential ore clusters, the mineralization is manifested by extensive fi lds of hydrothermal-metasomatic alterations (propylites and quartz-sericite-pyrite metasomatites). Recommendations are given for follow-up large-scale geological survey and prospecting in the area of the potential ore clusters.","PeriodicalId":19636,"journal":{"name":"Ores and metals","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141668410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
