Description

This dataset includes a collection of individual measurements of bedding, foliations and lineations from the so-called Central Unit and its surrounding bedrock, located in southwest Iberia (Portugal). Data were collected in 2023 and 2024. Planar and linear data are divided into several groups, depending on the type, time of formation, and ascription to tectonostratigraphic units. Bedding is referred to as S0. Foliation and lineation measurements refer to the orientation of the local main foliation (Sn) and specific type of lineation observed in the field (fold axis / crenulation, stretching, and mineral). Plane measurements are given as dip direction and dip, while line measurements are given as plunge and trend. The structural dataset includes UTM coordinates (Zone 29N, European Datum 1950) indicating the location of individual measurements.

Steps to reproduce

Structural measurements were carried out with a geological compass and annotated on a 1:25,000 scale and assisted by a rugged tablet with GPS and GIS technologies. Base maps (topographic and orthophotos) were obtained from the Centro de Informação Geoespacial do Exército (CIGeoE), Portugal.
