Effects of low‐tech, process‐based restoration on riparian plant communities and soil moisture of streams in the Northern Great Plains (NGP) of the United States

Restoration Ecology, EarlyView.
Abstract Introduction Process‐based restoration is novel in livestock production systems of the Northern Great Plains (NGP), and limited region‐specific evidence can impede adoption. We investigated the effects of methods such as beaver dam analogs (BDAs) on NGP plant communities.

Business Participation in Regulation: A Multifocal Perspective on Management Studies

Regulation &Governance, EarlyView.
ABSTRACT This paper conceptualizes how regulation is viewed in management studies in the context of business participation in regulation and explores its implications. We theorize six lenses through which management studies understand regulation: as competitive advantages, boundaries, forums, principles, systems, and cognitive frames.

Evolution Model for the Paleoproterozoic Talvivaara Mudstone‐Hosted Ni‐Zn‐Cu‐Co Deposit in Fennoscandia

Terra Nova, EarlyView.
ABSTRACT The Paleoproterozoic Talvivaara mudstone is a very large sulfidic Ni‐Co deposit that records enhanced organic matter accumulation during the global Shunga Event. Here, rock geochemistry and microscale S and Fe isotope composition of in situ pyrrhotites and pyrites are studied in well‐characterised, well‐preserved drill core samples.

Organic matter characteristics in black shales of the southwestern paleogene N'kapa formation, Douala Sub-basin Cameroon: Evidence from stable isotopes and rock-eval pyrolysis

Evolving Earth
Shallow marine black shales from outcrops, river channels, drilled and dug wells in Dibombari-Kompina-Mian (Stage-1) and Pendanboko (Stage-2) of the Paleogene N'kapa Formation in Douala Sub-basin were studied.

From Siliciclastics to Carbonates and Black shales: Deciphering Sedimentary Continuity and Discontinuity in the Devonian Landscapes of the Volga-Ural Petroleum Province

Georesursy
Analyses of the three predominant types of sedimentation – siliciclastic, carbonate and black shale – revealed their discontinuity/continuity across various facies environments within the Middle and Late Devonian of the central part of the Volga-Urals ...

Paleoenvironmental reconstruction and carbon and sulfur isotopes perturbation in black shales of the Paleocene Bolander member in the N’kapa Formation, Douala Sub-basin Cameroon

Geosystems and Geoenvironment
Black shales deposited across the Paleocene Bolander member of the N’kapa Formation are considered important source rock and shale gas reservoirs in the Douala sub-basin.

Mineralogy and geochemistry of the Cambrain Shuijingtuo Formation black shales from Western Hubei, China: implications on enrichment of critical metals and paleoenvironment

Frontiers in Marine Science
Black shales have attracted the attention of numerous researchers not only due to their high potential as hydrocarbon source rocks and shale gas reservoirs, but also to the enrichment of critical metal elements in black shale series.

Black shales – an unconventional source of noble metals and rhenium

Записки Горного института
The content of noble metals and rhenium in the Lower Paleozoic black shales of the eastern Baltic paleobasin in Russia was estimated. Shales are enriched in platinoids (PGM to 0.12 g/t) and rhenium (to 1.54 g/t).
