The Correction Notice in the Swiss Journal of Geosciences addresses an error in Fig. 9 of an article by Mählmann et al. The corrected figure displays the stability ranges of clay minerals and facies indicative minerals correlating with the Kübler-Index. The authors have made the necessary corrections to the original article, ensuring accuracy in their research. [Extracted from the article]

Analysis of offshore seismic lines suggests that a strong relationship exists between tectonic structures and fluid migration in accretionary prisms. However, only few field analogues of plumbing systems and their tectonic frameworks have been investigated in detail until now. The uplifted accretionary prism of the Hikurangi Margin (North Island, New Zealand) exposes early to late Miocene mudrocks in coastal cliffs of Cape Turnagain and in the Akitio syncline, south-east of the Pongaroa city. These outcrops display tubular carbonate concretions corresponding to complex subsurface plumbing networks of paleo-seeps within Miocene trench slope basins. We present here, new results on the spatial distribution of these tubular carbonate concretions, with particular attention to their relation to tectonic structures. In the Pongaroa area, tubular carbonate concretions in lower Miocene mudrocks occur along a N-S trend, while in middle Miocene strata they occur along a NNE-SSW direction. The N-S trend parallels a major fault zone (i.e. the Breakdown fault zone), which separates two wide synclines, the Waihoki and the Akitio synclines. During the Early-Middle Miocene, the Breakdown fault zone controlled the evolution of the Akitio trench slope basin constituting its western edge. The NNE-SSW strike parallels the axis of the Akitio syncline and is also parallel to the present-day subduction front. Our results therefore show that tubular concretions are parallel to post-Middle Miocene second order folding and thrusting in the northeastern limb of the Akitio syncline. In the Cape Turnagain area, tubular concretions occur in the western limb of the Cape Turnagain syncline, in the footwall of the major seaward-verging Cape Turnagain fault. This suggests that fluid migrations may occur not only in the crests of anticlines, as observed offshore for present-day plumbing system of cold seeps, but also in the footwalls of thrust faults. All these observations show that the spatial distribution of tubular concretions is controlled by regional tectonic structures with paleo-fluid migrations related to major deformation episodes of the accretionary prism. Thus, we distinguish three episodes events that likely triggered fluid migration leading to the formation of the tubular concretions: (1) In the Early Miocene, shortly after the onset of development of the Akitio trench slope basin, on its inner (western) edge; (2) During the late Middle Miocene, during an extensional deformation episode on the western limb of the Akitio trench slope basin; (3) At the end of the Late Miocene, during a second major shortening period at the footwall of major thrust fault, such as in the Cape Turnagain area.

High-grade metamorphic soles in NE Bosnia and Herzegovina make part of the Krivaja-Konjuh ophiolite complex (KKOC), which is one of the most important constituents of the Jurassic ophiolite mélange of the Central Dinarides. Several rock types were distinguished within the investigated metamorphic suite - sapphirine and corundum amphibolites, garnet-clinopyroxene±orthopyroxene amphibolites, clinopyroxene±garnet amphibolites, amphibolites per se and clinopyroxene+plagoclase±garnet gneisses. Peak temperature and pressure conditions calculated from different mineral pairs were estimated to range between 850 and 1100°C at 1.1 to 1.3 GPa. A prograde multi-stage metamorphic history of analyzed rocks was followed by the post-peak relaxation witnessed in decomposing porphyroblasts of garnet and ubiquitous formation of amphibole and orthopyroxene rims around clinopyroxene. The whole-rock chemical composition of magmatic protoliths largely defines it as cumulates from supra-subduction zones and scarcely as MORB-like tholeiitic mafic extrusives. Their origin is linked to near-ridge crust generation of a back-arc basin. Following the Middle Jurassic contraction of Neotethyan a portion of these rocks was likely entrained in an incipient subduction/thrusting system characteristic for the formation of metamorphic soles. According to geological evidences, and most notably, the age of radiolarians taken from KKOC basalts, the formation of metamorphic sole rocks must have followed a rapid transition in the Dinaridic Neotethys geotectonic setting before its final obduction onto the Adria margins in the next 15 Ma before the end of Jurassic.

Excavations of Hellenistic necropolises in ancient Issa located on the island of Vis in coastal Croatia revealed significant amounts of pottery, mostly tableware, dated from the second half of the 4th to the 1st c. BCE. Recovered pottery contained different stylistic forms thought to have been produced locally or imported. The goal of this study was to report on technological and compositional aspects of pottery economics embedded in the frame of social development of Issaean society. For this purpose, a set of 42 samples was analysed by X-ray diffractometry, polarization and electron microscopy, X-ray fluorescence, and automated electron microscopy. The results of archeometric inquiry combined with stylistic traits showed most of the vessels were produced locally whereby the procurement of raw material was dependent on the local occurrences of Terra Rossa. This required a high level of manufacture organisation, defining Issa as a presumably wellestablished Hellenistic city already in the second half of the 4th c. BCE. At the time the city maintained a strong exchange with the Italian South as suggested by excavated red figure and Gnathia pottery characterized by the superior production technologically compared to local imitations. A rare example of recovered amphoriskoi and their distinct material characteristics provided a strong indication of the presence of Levantine pottery in Issaean graves which, until now, has not been attested in the Eastern Adriatic. Such a finding speaks of the involvement of Issa in the Late Hellenistic networks of economic and cultural seaborne connectivity between the Adriatic and the Eastern Mediterranean and introduces Issa as a far-flung market of, at the time popular Levantine luxury products.
