Caledonian metamorphism of metasediments from Franz Josef Land
Gff, 2019 The petrography, detrital zircon age distribution and 40Ar–39Ar ages of three samples from the Nagurskaya drill core of westernmost Franz Josef Land have been analyzed and are compared to similar rocks from the Lomonosov Ridge.

REE patterns for apatites from Proterozoic phosphatic metasediments, Finland [PDF]
Bulletin of the Geological Society of Finland, 1983 Several occurrences of uranium- and apatite-bearing metasediments are known in the Precambrian of Finland. The characteristic rock types in the occurrences: metaphosphorite, apatite-bearing carbonate and calc-silicate rocks and apatite-quartz-feldspar ...

Geophysical Research Letters, 2021 The in situ state and properties of sediments entrained along subduction megathrusts exert key controls on their mechanics and slip behavior. Low seismic velocity and high Vp/Vs are hypothesized to indicate highly elevated fluid pressure, and are invoked

Microfossils in metasediments from Prins Karls Forland, western Svalbard
Polar Research, 1988 The stratigraphic importance of fossils is never more apparent than in attempts to unravel the complexities of metamorphic terrains. The age and stratigraphic relationships of the thick metasedimentary and metavolcanic succession of Prins Karls Forland ...

Metamorphic evolution of Verrucano metasediments in northern Apennines: new petrological constraints
European Journal of Mineralogy, 1998 The Triassic Verrucano metasediments largely crop out along the mid Tuscan ridge, in the northern Apennines. The metasediments mainly consist of ferriferous quartzites and Al-rich metapelites and contain a specific mineralogy which lead to the ...

Uranium Minerals in the Radlovac Series Metasediments at Mt. Papuk, Croatia
Geologia Croatica, 2007 Applying a combination of different methods – X-ray diffraction, scanning electron microscopy, gamma-spectroscopy and X-ray spectroscopy, a suite of uranium minerals, meta-torbernite, meta-uranospinite and meta-zeunerite was identified in metasediments ...
