Mineralogy and chemistry of a new halloysite deposit from the Rio de Janeiro pegmatite province, south-eastern Brazil

Autor: Julio Cezar Mendes, Francisco José da Silva, Reiner Neumann, Luiz Carlos Bertolino, Victor Matheus Joaquim Salgado-Campos

Publikováno v: Clay Minerals. 56:1-15

Halloysite is a 1:1 dioctahedral clay mineral that has been studied widely for applications in nanotechnology and as a mineral exploration guide for recognizing regolith-hosted heavy rare earth element (HREE) deposits. In Brazil, pegmatites from the

Publikováno v: Journal of South American Earth Sciences. 111:103490

The presence of the fern Weichselia in a restricted sedimentary interval of a drilling core in the Parnaiba Basin (Brazil) was used as a lead for paleoenvironmental interpretation integrating paleobotanical, palynofacies, palynological, organic petro

Publikováno v: Journal of South American Earth Sciences. 110:103329

The Aptian Crato Member of the Araripe Basin is a 50-m-thick succession of laminated limestones alternated with siliciclastic rocks. This unit has been receiving attention worldwide mainly because it is one of the most famous fossil Konservat-Lagerst
