Podemos dividir a foliação em dois grupos, as foliações contínuas e as descontínuas. Nas foliações contínuas, todos os minerais seguem a mesma orientação na rocha, já na descontínua, ocorre mais de uma orientação preferencial dos minerais. #MicrotectonicSeries #SimoesCollection

Foliation can be divided into two groups: continuous and discontinuous foliation. In continuous foliation, all minerals align in the same direction within the rock, whereas in discontinuous foliation, there is more than one preferred orientation of the minerals.

EN| Did you know that rocks have their own stories written in their structures? 🪨 Foliation is one of these stories, divided into two main categories:

Durante esse processo, novos minerais podem se cristalizar seguindo a foliação estabelecida. A classificação da foliação é baseada na granulação e na geometria do arranjo dos minerais na rocha.

Alguns exemplos de foliações incluem: Clivagem Disjuntiva, Clivagem Ardosiana, Clivagem de Crenulação, Xistosidade e Xistosidade de Crenulação. Cada uma delas conta uma parte da história geológica da nossa Terra! 🌍✨ #SimoesCollection #MicrotectonicsSeries #Unesp
