PETROGRAPHY AND THERMODYNAMIC REACTIONS OF SOME OF THE ROCKS IN THE BANKET SERIES OF THE TARKWAIAN SUPERGROUP

Autor: Matthew Coffie Wilson, Lydia Nnipaa Osei Opuni

Publikováno v: Geological Behavior, Vol 07, Iss 01, Pp 22-29 (2023)

The Banket Series, which is a paleoplacer deposit, is the third formation in the stratigraphy of Tarkwaian Supergroup. This project seeks to study petrographically; the lithologies in the banket series to confirm the rocks identity as already known

Locating hydrogen positions in the autunite mineral metatorbernite [Cu(UO2)2(PO4)2·8H2O]: a combined approach using neutron powder diffraction and computational modelling

Autor: Fiona M. MacIver-Jones, Polly Sutcliffe, Margaret C. Graham, Carole A. Morrison, Caroline A. Kirk

Publikováno v: IUCrJ, Vol 8, Iss 6, Pp 963-972 (2021)

Metatorbernite [Cu(UO2)2(PO4)2·8H2O] is a promising remediation material for environmental uranium contamination. Previous X-ray diffraction studies have been unable to definitively locate hydrogen positions within metatorbernite, which are key to d

Climatic controls on soil clay mineral distributions in humid volcanic regions of Sumatra and Java, Indonesia

Autor: Han Lyu, Tetsuhiro Watanabe, Yoriko Ota, Arief Hartono, Markus Anda, Randy A. Dahlgren, Shinya Funakawa

Climate and parent material are considered the primary factors determining the distributions of soil clay (secondary) minerals, but their influence has not been rigorously elucidated for tropical volcanic soils. Herein, we investigated soil secondary

A combination of neutron powder diffraction and ab initio random structure searching was used to locate hydrogen positions in the crystal structure of metatorbernite [Cu(UO2)2(PO4)2·8H2O], a common autunite mineral that shows promise for uranium rem

Aluminum hydroxy-interlayered minerals and chemical properties of a subtropical Brazilian Oxisol under no-tillage and conventional tillage Argilominerais 2:1 com hidróxi-Al e atributos químicos de um Latossolo Bruno subtropical sob sistemas de plantio direto e convencional

Autor: Alberto Vasconcellos Inda, José Torrent, Vidal Barrón, Cimélio Bayer

Publikováno v: Revista Brasileira de Ciência do Solo, Vol 34, Iss 1, Pp 33-41 (2010)

No tillage systems significantly influence the soil system, but knowledge about the effects on the mineralogy of tropical and subtropical soils is limited. This study evaluated the long-term effects (26 years) of no-tillage (NT) on aluminum hydroxy-i

Publikováno v: Journal of Hazardous Materials
Perez, J P H, Schiefler, A A, Rubio, S N, Reischer, M, Overheu, N D, Benning, L G & Tobler, D J 2021, ' Arsenic removal from natural groundwater using ‘green rust’ : Solid phase stability and contaminant fate ', Journal of Hazardous Materials, vol. 401, 123327 . https://doi.org/10.1016/j.jhazmat.2020.123327

Arsenic (As) contamination in groundwater remains a pressing global challenge. In this study, we evaluated the potential of green rust (GR), a redox-active iron phase frequently occurring in anoxic environments, to treat As contamination at a former
