The Hirnantian carbon isotopic excursion (HICE) was characterized by a positive δ 13 C
excursion (up to~+ 7‰) of oceanic dissolved inorganic carbon (DIC). However its …

Fractured rocks of impact craters may be suitable hosts for deep microbial communities on
Earth and potentially other terrestrial planets, yet direct evidence remains elusive. Here, we …

In central parts of the Scandinavian Caledonides, detrital zircon signatures provide evidence
of the change in character of the Baltoscandian crystalline basement, from the characteristic …

Nappes of continental outer and outermost margin affinities (Middle Allochthon) were
transported from locations west of the present Norwegian coast and thrust eastwards onto …

Abstract The Late Ordovician Period witnessed the second largest mass extinction in the
Phanerozoic Eon and the Hirnantian glaciation. To infer ocean redox conditions across the …

Based on δ13C data from two drillcores recovered from the Siljan district, we present a first
continuous carbon isotope record of the upper Tremadocian lower Katian limestone …

The Scandian mountains in northwestern Sweden are dominated by the eastern part of the
Scandinavian Caledonides, an orogen that terminated during the middle Paleozoic with …

Recent discoveries of extant and fossilized communities indicate that eukaryotes, including
fungi, inhabit energy-poor and anoxic environments deep within the fractured igneous crust …

Abstract The Middle Ordovician conodont genera that are suitable for palaeoenvironmental
interpretations from the epicontinental Baltoscandian platform have been identified and …

Different parts of a Tonian–Early Devonian sedimentary succession, covering Proterozoic
crystalline basement, occur along the erosional front to the Caledonide orogen, as outliers …
