Goldschmidt Conference}, unique-id = {3014225}, abstract = {The internal part of the CPR is a young extensional basin, which was formed during the Miocene. The central part of the area went through considerable thinning during this extension, when the crust was thinned from its original 50-60 km thickness to the present 25-30 km. The lower crust was sampled by alkaline basaltic volcanoes after the Miocene extension. The granulite xenoliths entrained in these basalts may bear imprints of this preceding extension event. The studied lower crustal xenoliths are metapelites and metabasic rocks having most commonly granoblastic texture. The rock-forming minerals (garnet, pyroxenes, feldspar, sillimanite, rutile) were measured by micro-FTIR spectrometry to determine their ‘water’ content and its substitution mechanism. The NAMs in granulites have usually very low ‘water’ content with bulk water contents typically below 100 ppm. In particular garnet is absolutely dry in all but four xenoliths. Feldspar and orthopyroxene show water contents typically below 100 ppm. The most ‘water’ rich minerals are clinopyroxene and sillimanite containing usually more than 100 ppm water. These concentrations are generally much lower than those have been reported for other lower crustal granulites from China [1] [2]. The very low ‘water’ content of NAMs in lower crustal granulite xenoliths from the central part of the CPR may be the consequence of the Miocene thinning. The accompanying localized fluid infiltration and potential increase in temperature may have resulted in heterogeneous melting and melt extraction from the lower crust having left behind a generally very dry residue. In summary the studied granulite xenoliths highlight that the lower crust in young extensional settings may be generally much depleted in ‘water’.}, keywords = {petrology; geodynamics; környezetgeokémia; földtan}, year = {2015}, pages = {1675-1675}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716; Németh, Bianka/0000-0001-9079-9773} } @article{MTMT:3004642, title = {Orthopyroxene-enrichment in the Iherzolite-websterite xenolith suite from Paleogene alkali basalts of the Poiana Rusca Mountains (Romania)}, url = {https://m2.mtmt.hu/api/publication/3004642}, author = {Nédli, Zsuzsanna and Szabó, Csaba and Dégi, Júlia}, doi = {10.1515/geoca-2015-0041}, journal-iso = {GEOL CARPATH}, journal = {GEOLOGICA CARPATHICA}, volume = {66}, unique-id = {3004642}, issn = {1335-0552}, abstract = {In this paper we present the petrography and geochemistry of a recently collected lherzolite-websterite xenolith series and of clinopyroxene xenocrysts, hosted in Upper Cretaceous-Paleogene basanites of Poiana Rusca (Romania), whose xenoliths show notable orthopyroxene-enrichment. In the series a slightly deformed porphyroclastic-equigranular textured series could represent the early mantle characteristics, and in many cases notable orthopyroxene growth and poikilitic texture formation was observed. The most abundant mantle lithology, Type A xenoliths have high Al- and Na-contents but low mg# of the pyroxenes and low cr# of spinel suggesting a low degree (< 10 %) of mafic melt removal. They are also generally poor in overall REE-s (rare earth elements) and have flat REY (rare earth elements + Y) patterns with slight LREE-depletion. The geochemistry of the Type A xenoliths and calculated melt composition in equilibrium with the xenolith clinopyroxenes suggests that the percolating melt causing the poikilitization can be linked to a mafic, Al-Na-rich, volatile-poor melt and show similarity with the Late Cretaceous-Paleogene (66-72 Ma) subduction-related andesitic magmatism of Poiana Rusca. Type B xenoliths, with their slightly different chemistry, suggest that, after the ancient depletion, the mantle went through a slight metasomatic event. A subsequent passage of mafic melts in the mantle, with similar compositions to the older andesitic magmatism of Poiana Rusca, is recorded in the pyroxenites (Fe-rich xenoliths), whereas the megacrysts seem to be cogenetic with the host basanite. The Poiana Rusca xenoliths differ from the orthopyroxene-enriched mantle xenoliths described previously from the Carpathian-Pannonian Region and from the Dacia block.}, keywords = {TRACE-ELEMENTS; CANARY-ISLANDS; Alkali basalt; Geochemistry; Paleogene; Peridotite xenoliths; Central-Europe; CENTRAL PANNONIAN BASIN; South Carpathians; METASOMATIC AGENT; SILICA ENRICHMENT; EAST SERBIA; LITHOSPHERIC MANTLE BENEATH; mantle xenolith petrology; S Carpathians}, year = {2015}, eissn = {1336-8052}, pages = {499-514}, orcid-numbers = {Szabó, Csaba/0000-0002-1580-6344} } @{MTMT:2943619, title = {Distinction of Variscan, Permo-Triassic and Alpine events in andalusite-biotite-sillimanite schists from Sopron area, W-Hungary}, url = {https://m2.mtmt.hu/api/publication/2943619}, author = {Dégi, Júlia and Török, Kálmán and Schuster, R}, booktitle = {CETEG 2015}, unique-id = {2943619}, year = {2015}, pages = {12-12} }
