“…However, the use of B as a paleosalinity indicator remains controversial (Eskenazy et al 1994;Lyons et al 1989). For example, an elevated concentration of B in coal may also be derived from hydrothermal activity (Lyons et al 1989), volcanic activity (Bouska andPesek 1983, Karayigit et al 2000), and climatic variations (Bouska and Pesek 1983).…”

Enrichment of U–Se–Mo–Re–V in coals preserved within marine carbonate successions: geochemical and mineralogical data from the Late Permian Guiding Coalfield, Guizhou, China

We present multi-element data on the super-highorganic-sulfur (SHOS; 5.19 % on average) coals of Late Permian age from Guiding, in Guizhou Province, China. The coals, formed on restricted carbonate platforms, are all highly enriched in S, U, Se, Mo, Re, V, and Cr, and, to a lesser extent, Ni and Cd. Although the Guiding coals were subjected to seawater influence, boron is very low and mainly occurs in tourmaline and mixed-layer illite/smectite. Uranium, Mo, and V in the coal are mainly associated with the organic matter. In addition, a small proportion of the U occurs in coffinite and brannerite. The major carrier of Se is pyrite rather than marcasite. Rhenium probably occurs in secondary sulfate and carbonate minerals. The U-bearing coal deposits have the following characteristics: the formation age is limited to Late Permian; concentrations of sulfur and rare metals (U, Se, Mo, Re, V, and in some cases, rare earth elements and Y) are highly elevated; the U-bearing coal beds are intercalated with marine carbonate rocks; organic sulfur and rare metals are uniformly distributed within the coal seams; and the combustion products (e.g., fly and bottom ash) derived from the coal deposits may have potential economic significance for rare metals: U, Se, Mo, Re, V, rare earth elements, and Y.

“…These two remarkable characteristics mean that REEs always occur in groups rather than as single elements (Henderson, 1984), and also enable REEs to act as a record of geochemical processes in natural systems (Taylor and McLennan, 1988). In coals, REEs are predominantly reported to occur in association with minerals (Lyons et al, 1989;Swaine, 1990). However, some studies have reported that REEs can be associated with both organic and inorganic matter in coals (Gluskoter et al, 1977;Van Der Flier-Keller, 1993).…”

The precise concentrations of rare earth elements (REEs) in Japanese Ashibetsu and Taiheiyo coals, in Indonesian Ambalut coal, and in Australian boghead coal have been determined, in order to compare the REE contents of the coals with those of plants and also to obtain further knowledge of the original plants from which these coals were formed. By leaching the coals after ashing using a 10% acetic acid solution, each coal sample was separated into two fractions: an acetic acid soluble fraction, and an acetic acid insoluble fraction. Our results show that three different types of chondritenormalized REE patterns are observed in the acetic acid soluble fraction of these coals. The acetic acid soluble fractions of the Ashibetsu, the Taiheiyo, and some of the Ambalut coals showed REE patterns identical to those of peat vegetation. Those of other Ambalut coals showed an REE pattern that was similar to that of tree trunks. The boghead coal showed a different REE pattern that was similar to algae, an origin that is also suggested from a maceral study. The REE patterns of the acetic acid soluble fraction can therefore be a useful proxy for determining the original plants that formed the coals.

“…Due to their chemical properties, REE are often studied as an entire group and rarely as single elements. REE in coal mostly occur in compounds with minerals (Lyons et al, 1989;Swaine, 1990). In hard coal, phosphate minerals, clay minerals and certain sulfides may act as potential REE carriers (Finkelman, 1982;Vassilev & Vasileva, 1996, 1997Ward et al, 1999;Ward, 2002;Willet et al, 2000;Worrall & Pearson, 2001;Yang & Zhou, 2001;Zhang et al, 2002).…”

PIERWIASTKI ZIEM RZADKICH Z POKŁADÓW WĘGLA WARSTW ORZESKICH POŁUDNIOWO-ZACHODNIEJ CZĘŚCI GZW (POLSKA)The subject of the research concerned the coal samples from 360/1, 361 and 362/1 seams of the Orzesze beds in the "Pniówek" coal mine. The obtained samples were characterized by low ash content -2.22-6.27% of the mass. The chemical composition of the ash indicates the presence of aluminosilicate minerals in the analyzed coal samples -most likely clay minerals, the presence of which has been confirmed in microscopic tests of the petrographic composition of channel samples of coal.The content of rare earth elements (REE sum) in the ash of the tested coal seams ranged from 364 to 1429 ppm. Variation of the REE content has been observed within a single seam.The fraction of REE indicates a relation with a mineral substance. No relation of the REE fraction and the presence of red beds has been found based on the tested samples.The content of REE found in ash, normalized to chondrites, is characterized by LREE enrichment in relation to HREE. The Eu anomaly is most likely related to tuff and tonstein levels occurring in Orzesze beds, which accompany the coal seams in the Upper Silesian Coal Basin (i.a., south of the studied area).The research has indicated that LREE in the tested samples are more related to the mineral substance, while HREE have a stronger affinity with organic substances.Keywords: rare earth elements (REE), coal, Orzesze beds, USCB Przedmiotem badań były próbki węgla z pokładów 360/1, 361 i 362/1 warstw orzeskich KWK Pniówek. Próbki te charakteryzują się niewielką zawartością popiołu 2,22-6,27% mas. Skład chemiczny popiołów wskazuje na obecność w analizowanych próbkach węgla minerałów z grupy glinokrzemianów najprawdopodobniej minerałów ilastych, których obecność była stwierdzona w badaniach mikroskopowych składu petrograficznego próbek bruzdowych węgla.Zawartości pierwiastków ziem rzadkich (suma REE) w popiołach badanych pokładów węgla wahają się od 364 do 1429 ppm. Obserwuje się zróżnicowanie zawartości REE w obrębie jednego pokładu. 158Udział REE wykazuje związek z substancją mineralną. Nie stwierdzono związku udziału REE, w badanych próbkach, z obecnością utworów pstrych w stropie karbonu.Zawartości REE oznaczone w popiołach, znormalizowane do chondrytów, charakteryzują się wzbogaceniem LREE wobec HREE. Anomalia Eu związana jest prawdopodobnie z występującymi w warstwach orzeskich (m.in. na północ od obszaru badań) Górnośląskiego Zagłębia Węglowego poziomami tufów i tonsteinów, które towarzyszą pokładom węgla.Badania wykazały, że LREE w badanych próbkach związane są raczej z substancją mineralną, natomiast HREE posiadają silniejsze powinowactwo z substancją organiczną.Słowa kluczowe: pierwiastki ziem rzadkich (REE), węgiel kamienny, warstwy orzeskie, GZW
