Comparisons of the Paleo-Mesoproterozoic large igneous provinces and black shales in the North China and North Australian cratons [PDF]
Fundamental Research, 2022 Comparisons of large igneous provinces (LIPs) and black shales from different cratons can provide important constraints on Precambrian paleogeographic reconstructions and a better understanding of the environmental effects of large-scale volcanic events.

Cu isotopes in marine black shales record the Great Oxidation Event. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance Redox-sensitive transition metals and their isotopes provide some of the best lines of evidence for reconstructing early Earth’s oxygenation history, including permanent atmospheric oxygenation following the Great Oxidation Event (GOE), ∼2 ...

Experimental Investigation of Mechanical Properties of Black Shales after CO₂-Water-Rock Interaction. [PDF]
Materials (Basel), 2016 The effects of CO2-water-rock interactions on the mechanical properties of shale are essential for estimating the possibility of sequestrating CO2 in shale reservoirs.

Environmental impact of mineralised black shales
Earth-Science Reviews, 2019 Black shales are sedimentary rocks containing >0.5% of organic carbon. They host polymetallic deposits which have been mined for Cu, Ni, Zn, Mn, P, Mo, V, U, Au and PGE (platinum group elements). Even sub-economic occurrences provide potential risk of acid rock drainage when exposed to oxic surface environment. The natural acid neutralisation potential

The origin of Cretaceous black shales: a change in the surface ocean ecosystem and its triggers. [PDF]
Proc Jpn Acad Ser B Phys Biol Sci, 2015 Black shale is dark-colored, organic-rich sediment, and there have been many episodes of black shale deposition over the history of the Earth. Black shales are source rocks for petroleum and natural gas, and thus are both geologically and economically ...

Lower Wenlock black shales in the northern Holy Cross Mountains, Poland: Sedimentary and geochemical controls on the Ireviken Event in a deep marine setting [PDF]
Geological Magazine, 2016 The stratigraphic variability and geochemistry of Llandovery/Wenlock (L/W) Series boundary sediments in Poland reveals that hemipelagic sedimentation under an anoxic/euxinic water column was interrupted by low density bottom currents or detached diluted ...
