[/ˈkɒmpɪtənt ˈstrætəm/]
nounpl: competent strata
estrato competente
1. In geology and structural geology, a layer of rock or sediment that is strong and rigid enough to transmit stress without deforming significantly, often forming the core of fold structures
The limestone layer acts as a competent stratum that controls the folding pattern of the overlying sediments.
A camada de calcário atua como um estrato competente que controla o padrão de dobramento dos sedimentos sobrejacentes.
2. A rock unit capable of supporting its own weight and resisting deformation under tectonic stress, as opposed to incompetent strata which deform plastically
During mountain building, the competent stratum remained largely unbroken while the incompetent layers folded around it.
Durante a formação de montanhas, o estrato competente permaneceu largamente intacto enquanto as camadas incompetentes se dobravam ao seu redor.
This is highly specialized technical terminology used primarily in geology, petroleum engineering, and structural geology. It is equally used in Brazil, Portugal, and English-speaking countries in academic and professional geological surveys. The term reflects the international nature of geological science and is rarely encountered outside professional and academic contexts.
