Structural Data from La Serena Massif

The dataset includes individual measurements of structural planes and lines that were collected in the vicinity of Zalamea de la Serena (Extremadura, Spain) in 2021 and 2022. Measurements were taken both from the Precambrian and Paleozoic metamorphic basement. This structural dataset was collected during fieldwork campaigns aimed at mapping major structures developed during the Cadomian and Variscan orogenies in the region.
The dataset is divided into separate spreadsheets, which included the following measurements:
• S0: bedding or primary planar anisotropies related to sedimentation. The dataset includes a specific spreadsheet for data obtained from within the Central Iberian Zone (CIZ), and is divided by the age of the strata (Cambrian, Ordovician, and Devonian).
• SC3: foliation formed during the third phase of Cadomian deformation in the region.
• LsC3: stretching lineation related to the foliation formed during the third phase of Cadomian deformation in the region.
• LmC3: mineral lineation related to the foliation formed during the third phase of Cadomian deformation in the region.
• SV1: foliation formed during the first phase of Variscan deformation in the region.
• DV1 fold axes: axes of folds formed during the first phase of Variscan deformation in the region.
• Li_S0-SV1: intersection lineation between bedding (S0) and SV1 foliation, which indicates the local orientation of the DV1 fold axes.
• SV2: foliation formed during the second phase of Variscan deformation recognized in the region, which is usually a crenulation cleavage.
• DV2 fold axes: axes of folds formed during the second phase of Variscan deformation in the region.
• SV3: foliation formed during the third phase of Variscan deformation in the region.
• LsV3: stretching lineation related to the foliation formed during the third phase of Variscan deformation in the region.
• LmV3: mineral lineation related to the foliation formed during the third phase of Variscan deformation in the region.
• DV3 fold axes: axes of folds formed during the third phase of Variscan deformation in the region.
• DV3 fold axes: axes of folds formed during the third phase of Variscan deformation in the region.
• LcV3: crenulation lineation related to the development of SV3. It represents the axes of folds formed during the third phase of Variscan deformation in the region.

Plane orientations are reported by their dip direction and dip, whereas line orientations are described by their trend and plunge.
The location of each individual measurement is provided using the ETRS89 Datum (UTM Zone 30) and expressed in UTM coordinates (in meters), including Northing and Easting.

本数据集收录了2021年至2022年在西班牙埃斯特雷马杜拉大区萨拉梅亚德塞雷纳附近区域采集的关于结构面及线的个体测量数据。测量工作涉及前寒武纪和古生代变质基底。该结构数据集系在旨在绘制该区域加多姆和瓦尔登海造山运动期间形成的重大结构的地调活动中收集而成。

数据集被划分为独立的电子表格，具体包括以下测量内容：
• S0：与沉积作用相关的层理或初级平面各向异性。数据集中包含一个专门针对中伊比利亚区（CIZ）获取的数据的电子表格，并根据地层年代（寒武纪、奥陶纪和泥盆纪）进行划分。
• SC3：区域加多姆变形第三阶段形成的片理。
• LsC3：与区域加多姆变形第三阶段形成的片理相关的拉伸线理。
• LmC3：与区域加多姆变形第三阶段形成的片理相关的矿物线理。
• SV1：区域瓦尔登海变形第一阶段形成的片理。
• DV1褶皱轴线：区域瓦尔登海变形第一阶段形成的褶皱轴线。
• Li_S0-SV1：层理（S0）与SV1片理之间的交线，指示了DV1褶皱轴线的局部方向。
• SV2：在区域识别出的瓦尔登海变形第二阶段形成的片理，通常为皱褶劈理。
• DV2褶皱轴线：区域瓦尔登海变形第二阶段形成的褶皱轴线。
• SV3：区域瓦尔登海变形第三阶段形成的片理。
• LsV3：与区域瓦尔登海变形第三阶段形成的片理相关的拉伸线理。
• LmV3：与区域瓦尔登海变形第三阶段形成的片理相关的矿物线理。
• DV3褶皱轴线：区域瓦尔登海变形第三阶段形成的褶皱轴线。
• LcV3：与SV3发展相关的皱褶线理，代表区域瓦尔登海变形第三阶段形成的褶皱轴线。

平面的方向通过倾伏方向和倾角进行报告，而线的方向则通过走向和倾伏进行描述。
每个个体测量的位置均采用ETRS89大地基准（UTM区域30）提供，并以米为单位表达UTM坐标（北向和东向）。
