Geotechnical properties of some kaolinite-rich Brazilian Vertisols
(Sociedade Brasileira de Ciência do Solo, 2022)
Spatial correlation between the composition of the clay fraction and contents of available phosphorus of an Oxisol at hillslope scale
(2013-01-01)
Relief is regarded as the abiotic factor most strongly influencing pedogenic processes at a local scale. The spatial correlations between the composition of the clay fraction (iron - Fe and aluminum - Al oxides, kaolinite ...
Deciphering the weathering processes using environmental mineralogy and geochemistry: Towards an integrated model of laterite and podzol genesis in the Upper Amazon Basin
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-02-01)
This article reports major results from collaborative research between France and Brazil on soil and water systems, carried out in the Upper Amazon Basin. It reveals the weathering processes acting in the partly inundated, ...
Viabilidade de aplicação das coberturas argilosas da região de Alfenas na indústra cerâmica
(2010-07-06)
The region of Alfenas, in the state of Minas Gerais, Brazil, is predominantly constituted of Pre-Cambrian rocks with well developed alteration profiles in association with colluvial and alluvial sediments. No study to date ...
Mineralogy of the clay fraction of Alfisols in two slope curvatures: III - spatial variability
(Sociedade Brasileira de Ciência do Solo, 2013-04-01)
O conhecimento da distribuição dos minerais da fração argila na paisagem permite o entendimento da influência do relevo no teor e nos atributos dos minerais como goethita, hematita, caulinita e gibbsita. Buscando entender ...
Caracterização química e mineralógica de azulejos portugueses do centro histórico de São Luís-MA (Brasil): Uma aproximação à mineralogia e à temperatura de queima das matérias-primas
(2013-01-01)
This work involved the first-ever characterization of antique Portuguese ceramic wall tiles in the Historic Center of São Luis do Maranhão, Brazil. The tiles were characterized by optical microscopy, X-ray diffraction (XRD) ...
Mineralogy, micromorphology, and genesis of soils with varying drainage along a hillslope on granitic rocks of the atlantic forest biome, Brazil
(Revista Brasileira de Ciência do Solo, 2019)
Minerals in the clay fraction of Brazilian Latosols (Oxisols): a review
(Clay Minerals, 2018)
Nucleation kinetics of crystalline phases from a kaolinitic body used in the processing of red ceramics
(Elsevier B.V., 2011-04-01)
The crystallization kinetics of red ceramic raw material from the western part of São Paulo State, Brazil, was examined by differential thermal analysis (DTA) and X-ray diffraction (XRD). The chemical composition of the ...
Physical attributes of kaolinitic and oxidic oxisols resulting from different usage systems
(Brazilian Archives of Biology and Technology, 2004-09-01)
A mineralogia da fração argila e os sistemas de uso exercem fundamental importância na estrutura do solo. Assim, objetivou-se avaliar atributos físicos de um Latossolo Vermelho Distrófico, caulinítico (LVd), e, de um ...
