Resumo
Transpressão representa a deformação por uma combinação entre contração e cisalhamento simples direcional e ao longo do mergulho (empurrão) de zonas de cisalhamento, em diferentes proporções. A deformação transpressiva é uma característica comum em diferentes orógenos, ao longo de margens convergentes de placas, e também em outros ambientes tectônicos. São revisados conceitos fundamentais para a compreensão da deformação transpressiva, em uma perspectiva histórica da evolução do conhecimento, a partir do acúmulo de observações de exemplos naturais e sofisticação dos modelos teórico-matemáticos. Além disso, a relação entre transpressão com alguns aspectos orogênicos importantes, como o magmatismo sintectônico, a partição da deformação e a exumação, também são abordados. Um estudo de caso, no limite entre ante-país e além-país no setor norte do Cinturão Dom Feliciano (Santa Catarina, Brasil), onde a deformação transpressiva regional culminou na partição da deformação em domínios estruturais, é apresentado como forma de ilustrar estes conceitos e relações.
