Petrography and isotope-geochemistry of the Bayandor Formation dolomites at the type section, south-west of the Zanjan [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2019 The Late Precambrian Bayandor Formation has a thickness of 402 m and consists of shale and sandstone with dolomite interlayers (with a thickness of about 2 to 8 m) in the type section of the south-west of Zanjan. Based on fieldwork studies lithofacies of

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction
Geophysical Monograph Series, Page 325-340., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

40Ar ∕ 39Ar age constraints on the formation of fluid-rich quartz veins from the NW Rhenohercynian zone (Rursee area, Germany) [PDF]
GeochronologyA substantial part of the subsurface geology in northwestern and central Europe is defined by the late Palaeozoic Variscan Orogeny (∼ 350 Ma). Our focus is mainly on veining in anchimetamorphic sedimentary rocks affected by this orogeny.
