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 ...

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.

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.

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.

The White Stone Band of the Kimmeridge Clay Formation, an integrated high resolution approach to understanding environmental change

, 2004
The Kimmeridge Clay is a Jurassic mudrock succession that shows Milankovitch Band climatic cyclicity. A key issue is to determine how the subtle changes that define this cyclicity result from climatic change.
