The main of them are following: 1) The texture and mineral composition of the majority of the macrochondrules does not differ from those of ordinary chondrules, thus indicating a similarity in formation conditions, 2) It is shown for the first time that the SiO2/MgO and FeO/(FeO+MgO) ratios of the fine-grained rims of the macrochondrules and one`s of chondrules in the Krymka meteorite are well correlated. This indicates to their coexistence in the same dusty environment of the protoplanetary nebula, 3) The unique characteristics of the two firstly found macrochondrules allowed us to detail conditions of their formation and existence in the protoplanetary nebula. A polyzonal graphite-bearing macrochondrule from the Krymka meteorite formed by accretional growth in a mineralogically variable dusty environment. Its complex evolutional history involved remelting and selective evaporation of the macrochondrule surface layer, accretion of an environmental dust, late formation of a fine-grained rim and migratory intrusion of an organic protomaterial and finally a metamorphic event that produced graphite. The melted surface of a macrochondrule from the Allende chondrite was notably affected by high-energy processes and instantaneous cooling in the protoplanetary nebula, 4) The rarity of macrochondrules in chondrites compared to typical chondrules is probably related to their priority destruction. This was caused by permanent movement and collision between them and other solid objects in the pre-agglomeration period of meteorite development.","PeriodicalId":53834,"journal":{"name":"Mineralogical Journal-Ukraine","volume":"12 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126162","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}

Proskurka","doi":"10.15407/mineraljournal.43.04.063","DOIUrl":"https://doi.org/10.15407/mineraljournal.43.04.063","url":null,"abstract":"In the Saltych anticlinorium of the West Azov, small intrusions of rocks of basic and ultrabasic composition are known in the middle reaches of the Obitochna, Kiltychiya and Burtychiya rivers and in the upper reaches of the Obitochna river. They are composed from amphibolized peridotites, pyroxenites, actinolithites, tremolithites, hornblendites, amphibole and other shales. These intrusions are considered \"fractured intrusions\", which are rooted in the already deployed rocks of the Archean age. In the stratigraphic scheme they are referred to the Novoselytske association. Intrusions break through the veins of syenites, pegmatites and aplite-like granites. Metaultrabasites, according to I.S. Usenko and G.L. Kravchenko, these are ultrabasic rocks of the normal series, which were formed, probably, because of differentiation of basaltic magma. The main and ultrabasic rocks of these intrusions have not been studied enough yet — their age, geodynamic conditions of formation have not been determined, the potential for minerals has not been fully revealed. For this purpose, we determined the microelement composition of meta-ultrabasites, metabasites and acid rocks by the ICP MS method and determined the age of monazite from veins of aplite-like granites that break through the metapyroxenites of the Kamyshuvatka intrusion. According to the obtained geochemical and mineralogical data, the vein rocks of medium and acid composition, which break through the intrusions of the ultrabasite-basite composition at the Saltych anticlinorium, have a core genesis. Zircon in them is relict, and syngenetic monazite was found only in the veins of aplite-like granites that break through the metapyroxenites of the Kamyshuvatka intrusion. According to the dating of this monazite, it has been determined that the upper age limit for the formation of intrusions of the ultrabasite-basite composition of the Novoselytske association is 2051.8±3.8 Ma. Peridotites and pyroxenites of these intrusions could be formed from melts of the depleted upper mantle, which were fractionated in intermediate magmatic chambers. In peridotites (#mg = 0.74-0.86) of the Kamyshuvatka intrusion and intrusion near the Reva farm, the Ni content (510-826 ppm) is lower than that of Clark for ultrabasic rocks, and the chromium content at the level of Clark and below it is Cr — 1250-2260 ppm. Positive anomalies of Ti and Eu indicate the processes of fractionation of the original magma of pyroxenites. The formation of intrusions of the ultrabasite-basite composition of the Saltych anticlinorium of the Azov megablock is probably connected with the activation of the Earth’s mantle about 2050 million years ago.","PeriodicalId":53834,"journal":{"name":"Mineralogical Journal-Ukraine","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126842","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 applied methods include sampling coal from mine workings and from core-samples duplicates of wells from 1981 to 2014; identification of the inorganic part of the coal seam, macroscopically diagnosed by standard mineralogical methods as sulfide, silicate and carbonate fractions. According to textural and structural features, they are divided into groups of syngenetic and epigenetic origin; the mineral composition of these two groups was determined by optical microscopy using MIN-8 and MBS-9 microscopes and by X-ray diffraction analysis. Fractional analysis of the density of coal from duplicates of the original samples was carried out to identify the substance of the inorganic part of the coal seam; Arsenic and Hg contents were determined by atomic absorption analysis in the substance of all initial and final samples; normalization of all values of Hg and As concentrations and technological parameters of coal; statistical processing of all geochemical information using Excel 2016 and Statistica 11.0, which included correlation and regression analysis; calculation of the coefficients of affinity of Hg and As with organic matter, the coefficients of the reduced concentration of the investigated elements, the coefficients of the reduced extraction of these elements in the fraction of different densities; construction of maps of normalized isoconcentrates; changes in the regional component of normalized content and gradient of normalized content were performed using the program Surfer 11. We found a genetic link between high concentrations of As and Hg in the coal seam k5 of the minefield Kapitalna with tectonic features, the Central overthrust and associated zones of increased fracturing. The accumulation of As and Hg in the coal seam k5 of the minefield Kapitalna, bound to the organic component of the coal seam, is epigenetic. The practical significance of the work is that their high concentration in the high-density fractions of coal will lead to their gravitational accumulation in the waste.","PeriodicalId":53834,"journal":{"name":"Mineralogical Journal-Ukraine","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67126853","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}
