LA-ICP-MS U-Pb geochronology on monazite: Geologic “date” and geologic event duration. Comment on the paper by H.-J. Massonne, European Journal of Mineralogy, DOI:10.1127/ejm/2016/0028-2575

We comment here a paper that is entirely built on a single sample of metapelites belonging to the Lukovitsa Formation in the Pirin-Pangaion unit. Some discrepancies in the interpretations of the author in respect of the facts established by himself as well as to long-known geological information for the same rocks and locality are pointed at. We emphasize that the “monazite formation event” corresponds to the interval of ca. 62–24 Ma, i.e., to the whole time of Paleogene uplift of the unit and the intrusion and exhumation of the Spanchevo (ca. 57 Ma) and Teshovo (ca. 32 Ma) plutons. The pretended HP metamorphic event cannot be inscribed in this time span.

Bubnovaite, (IMA 2014-108), ideally K2Na8Ca(SO4)6, is a new mineral found in fumaroles of the 2012–2013 Tolbachik fissure eruption, Kamchatka peninsula, on the new cinder Naboko cone. The samples of bubnovaite were found in a cavity on the NNE flank of the cone at the depth of 30 cm. The temperature of gases at the sampling location was more than 500 °C. The mineral forms fine-grained, light blue, dendritic aggregates, consisting of colorless, transparent, tabular crystals of maximum dimension 0.14 mm, that were recovered with the aid of a long stick and metallic cap to grab samples from the fumarole vent. Bubnovaite is associated with aphthitalite, (K,Na)3Na(SO4)2, and thenardite, Na2SO4. Crystals of bubnovaite are brittle with a white streak and a vitreous luster. Hardness and density were not measured due to the lack of suitable material. The expected Mohs hardness is 2–3; D calc = 2.656 g/cm3. The mineral is unstable in air and becomes white and non-transparent …

Alpine corundum-bearing veins from the Etirol-Levaz Austroalpine continental slice (Valtournenche, Aosta, Italy)

This short manuscript presents a detailed investigation into the metamorphic evolution of a unique corundum-bearing chloritite from the layered metagabbro body within the Etirol-Levaz continental slice in Valtournenche, Aosta, Italy. This sample represents the first occurrence of corundum and hogbomite-bearing mafic rocks in the Western Italian Alps. The data presented here mostly summarizes the content of the article Regis et al. (submitted to European Journal of Mineralogy).

From the Fortschritte der Mineralogie to the European Journal of Mineralogy: a case history

Fortschritte der Mineralogie , the journal of the Deutsche Mineralogische Gesellschaft (DMG), was founded in 1911. Until 1988, a total of 66 volumes appeared, although with some interruptions due to World Wars I and II. In contrast to other mineralogical periodicals the Fortschritte published predominantly review articles in all fields of mineralogy. From 1960 on part of the contributions were written in English, thus conforming to the trend towards English as a lingua franca in natural sciences, including geosciences. On August 1, 1988, the Deutsche Mineralogische Gesellschaft, the Societe francaise de Mineralogie and the Societa Italiana di Mineralogia e Petrologia founded the European Journal of Mineralogy (EJM) and, at the same time, decided to discontinue their own traditional journals; the same holds true for the Sociedad Espanola de Mineralogia who joined in editing the EJM in 2004. During the two decades of existence, nearly 1900 paper have been published by the EJM in the fields of crystallography (18 %), systematic, regional and applied mineralogy (39 %) and petrology (43 %). The overwhelming majority of the papers (more than 80 %) was written by European authors, i.e. 22 % from Italy, 20 % from Germany, 11 % from France, 5 % from the United Kingdom, 3% from Spain, Switzerland, and Austria, resp., and 5 % from Russia. The USA contributed 5 % of the papers, Canada 3 % and Japan 2.5 %. The EJM has established itself as an internationally respected, high rank European periodical in all fields of mineralogy with an impact factor ranging from 1.1 to 1.45.

The historical corner

The following paper by Martin Okrusch and Hans-Ulrich Bambauer does not fit the strict template of a publication in the European Journal of Mineralogy . It is not a report on scientific results in the mineralogical sciences as normally demanded by the EJM . Rather, it reports on the conception as an idea in 1974, the birth in 1989 and the growth to maturity of the actual vehicle used to disseminate such information, namely the EJM itself. As such, it is a historical account and of necessity may reflect personal views. On the other hand, it is a fascinating narrative written by authors personally involved in making decisions for the future against a back-drop of the usual inertia of many rank-and-file members of national societies. In many ways, the EJM story mirrors the trials, tribulations and pitfalls experienced by Europe in drawing closer together in the post-war era. It was with the above background in mind that the members of the managing committee voted to include the following essay by Martin Okrusch and Hans-Ulrich Bambauer in …

Twenty years of EJM, or, a successful journal on a new track

The year 2007 has witnessed many changes for the European Journal of Mineralogy. With the retirement of Michele Canaple, the EJM founding editorial secretary who was supported by the Centre national de la recherche scientifique (CNRS), the entire production process had to be reorganized, a process involving many thorough discussions between the owner Societies (DMG, SEM, SFMC and SIMP) and our Publisher, Schweizerbart. As a result, we now have a new printer and a new type-setter, specialized in electronic scientific literature, who have ensured such a smooth transition that it may have remained unnoticed by most readers. Nonetheless, authors will certainly have perceived the change, because they now receive electronic proofs and see …

The editorial secretary addresses the authors

You, who have chosen to publish your results in the European Journal of Mineralogy and thus had many contacts with me, you will think “Why is the editorial secretary addressing us now, through the Journal? She never did so before! What is going on? What does she want to say to us?” Before knowing so … you will have to be patient!!! I have ensured, for several years, the publication of the French journal «Bulletin de Mineralogie» (formerly Bulletin de la Societe francaise de Mineralogie et de Cristallographie ), which some of you are familiar …

The Turiy Massif, Kola Peninsula, Russia: Isotopic and Geochemical Evidence for Multi-source Evolution

The Turiy Massif, lying within the Kandalaksha Graben, and on the southern coast of the Kola Peninsula, contains carbonatites, phoscorites, melilitolites, ijolites and pyroxenites within one central and four surrounding satellite complexes. Sr–Nd isotopic data from the central complex phoscorites and carbonatites, and the nearby Terskii Coast kimberlites, combined with other recently published data on the Devonian Kola Alkaline Province, allow us to redefine the position of the Kola Carbonatite Line (KCL) of Kramm (European Journal of Mineralogy 5, 985–989, 1993). We propose that the revised-KCL mantle sources include a lower-mantle plume, and a second enriched source, which also contributed to the Terskii Coast and Archangelsk kimberlites. The Turiy Massif silicate rocks and northern complex carbonatites have more enriched isotopic signatures than the distinct, and depleted signatures of the central complex phoscorites and carbonatites, particularly with respect to εSr. This is probably due to the contamination of parental magmas, originally derived from the KCL end-members, by crustal material. The phoscorites and carbonatites show unusually enriched stable isotope δ13CPDB values with respect to their conjugate δ18OSMOW values. The trace element signatures of the silicate rocks are generally consistent with derivation from the magma sources proposed above.
