Resumo: | Soil evolves in landscapes in a natural process in which soil properties are gradually transformed. However, the transformation of argic to ferralic horizons in basic rock-derived soils under tropical conditions is poorly understood. Depending on the position of the soil profiles in landscape, evidence of pedogenetic transformation between different horizons might indicate the formation and destruction of aggregates with shiny faces. This study aimed to determine pedogenetic changes in basic rock-derived profiles in a toposequence, because soils derived from mafic rocks are not abundant in the study region (Pinheiral, Rio de Janeiro State, Brazil). Trenches were dug at the summit (P1), upper (P2), middle (P3), and lower (P4) thirds along the toposequence. The morphological, physical, chemical, mineralogical, and micromorphological properties of the profiles were characterized, and a weathering index was calculated from X-ray fluorescence element values. All profiles had chemical and physical properties indicating an advanced degree of weathering resulting from the parent material and tropical climate conditions. In P1 and P4 that were classified as Nitossolos, the most evident pedogenetic processes were ferralitization and nitidization, due to the advanced degree of weathering, accumulation of oxyhydroxides and kaolinite in the horizons, and formation of textural pedofeatures by mechanical-hydric stress and evidence of the illuviation process. Profiles P2 and P3 revealed a ferralitization process and were classified as Latossolos. Absence of shiny macromorphological ped faces in some Bw horizons, and their micromorphological coexistence in Bt and Bw horizons within the same profile were associated with the transformation of the blocky into a granular microstructure, suggesting argic-ferralic horizon transformation. |

No entanto, a transformação de horizontes argicos em ferrálicos em solos derivados de rochas básicas sob condições tropicais é pouco compreendida. Dependendo da posição dos perfis de solo na paisagem, evidências de transformação pedogenética entre diferentes horizontes podem indicar a formação e destruição de agregados com faces brilhantes. Este estudo teve como objetivo determinar alterações pedogenéticas em perfis derivados de rochas básicas em uma topossequência, pois solos derivados de rochas máficas não são abundantes na região de estudo (Pinheiral, Estado do Rio de Janeiro, Brasil). Trincheiras foram cavadas no cume (P1), terços superior (P2), médio (P3) e inferior (P4) ao longo da topossequência. As propriedades morfológicas, físicas, químicas, mineralógicas e micromorfológicas dos perfis foram caracterizadas e um índice de intemperismo foi calculado a partir dos valores dos elementos de fluorescência de raios X. Todos os perfis apresentavam propriedades químicas e físicas indicando um avançado grau de intemperismo resultante do material original e das condições climáticas tropicais. Nos P1 e P4 classificados como Nitossolos, os processos pedogenéticos mais evidentes foram a ferralitização e a nitidização, devido ao grau avançado de intemperismo, acúmulo de oxihidróxidos e caulinita nos horizontes, e formação de pedocaracterísticas texturais por estresse mecânico-hídrico e evidências de o processo de iluviação. Os perfis P2 e P3 revelaram processo de ferralitização e foram classificados como Latossolos. A ausência de faces ped macromorfológicas brilhantes em alguns horizontes Bw, e sua coexistência micromorfológica nos horizontes Bt e Bw dentro do mesmo perfil foram associadas à transformação da microestrutura em bloco em granular, sugerindo transformação do horizonte árgico-ferrálico.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOGRAFIARevista Brasileira de Ciência do SoloSolos - formaçãoSolos - classificaçãoPedogenesisSoil classificationFerralitizationNitidizationTextural pedofeaturesGenesis and transformation of basic rock-derived soils with shiny ped faces under tropical conditionsGênese e transformação de solos básicos derivados de rochas com faces planas brilhantes em condições tropicaisinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.rbcsjournal.org/article/genesis-and-transformation-of-basic-rock-derived-soils-with-shiny-ped-faces-under-tropical-conditions/Marcos Gervasio PereiraRafael Cipriano da SilvaMiguel CooperLúcia Helena Cunha Dos AnjosDeyvid Diego Carvalho MaranhãoFábio Soares de Oliveiraapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;

Soil evolves in landscapes in a natural process in which soil properties are gradually transformed. However, the transformation of argic to ferralic horizons in basic rock-derived soils under tropical conditions is poorly understood. Depending on the position of the soil profiles in landscape, evidence of pedogenetic transformation between different horizons might indicate the formation and destruction of aggregates with shiny faces. This study aimed to determine pedogenetic changes in basic rock-derived profiles in a toposequence, because soils derived from mafic rocks are not abundant in the study region (Pinheiral, Rio de Janeiro State, Brazil). Trenches were dug at the summit (P1), upper (P2), middle (P3), and lower (P4) thirds along the toposequence. The morphological, physical, chemical, mineralogical, and micromorphological properties of the profiles were characterized, and a weathering index was calculated from X-ray fluorescence element values. All profiles had chemical and physical properties indicating an advanced degree of weathering resulting from the parent material and tropical climate conditions. In P1 and P4 that were classified as Nitossolos, the most evident pedogenetic processes were ferralitization and nitidization, due to the advanced degree of weathering, accumulation of oxyhydroxides and kaolinite in the horizons, and formation of textural pedofeatures by mechanical-hydric stress and evidence of the illuviation process. Profiles P2 and P3 revealed a ferralitization process and were classified as Latossolos. Absence of shiny macromorphological ped faces in some Bw horizons, and their micromorphological coexistence in Bt and Bw horizons within the same profile were associated with the transformation of the blocky into a granular microstructure, suggesting argic-ferralic horizon transformation. |
