Financialization and an emerging “green investor state”: Examining China's use of state‐backed funds for green transition

Regulation &Governance, Volume 19, Issue 2, Page 349-369, April 2025.
Abstract China is simultaneously enacting a state‐led financialization of governance and a prioritization of environmental objectives. Resultingly, dedicated state‐backed green funds have grown in scale beyond US$70 billion. Drawing on interviews, policies, and financial databases, we examine these funds through policy document analysis, descriptive ...

Hydrous Asthenosphere Underneath the Northern Pannonian Basin

Terra Nova, Volume 37, Issue 3, Page 164-174, June 2025.
ABSTRACT This study reveals the structural hydroxyl content in clinopyroxenes of three cumulate xenoliths from the Nógrád‐Gömör/Novohrad‐Gemer Volcanic Field (northern Pannonian Basin), with values ranging from 275 to 384 ppm. Based on these data, the water content of the equilibrium parental alkali basaltic melt was estimated to be between 1.5 and 2.1

Schist Belts of the Benin‐Nigeria Shield Reveal a Neoproterozoic History

Terra Nova, EarlyView.
ABSTRACT Belts of metasedimentary rocks (schist belts) in the Benin‐Nigeria Shield (BNS) are investigated for the first time using U–Pb dating and Lu‐Hf isotope analysis of detrital zircons. We report maximum depositional ages that place their deposition firmly in the Neoproterozoic and link them with strata in the Dahomey Belt, the central African ...
